Keynote: Our experiences in 7 years sealing veins-a follow- up study conducted on 2250 truncal saphenous veins in 1250 cases
Biography:
Ulf Thorsten Zierau is the Head of Vascular Surgery at the Charité. After specialist examination in surgery in 1994, he continued the training in the field of vascular surgery, first at the venous center Malente (Mühlenberg Clinic), then at the 2nd University Clinic Cologne. He passed the Vascular Surgery Examination in 1996 and beginning of independent clinical work as a Senior Physician and Head of the Department of Vascular Surgery at the Gransee Hospital. Later, he turned to cathederal medicine; study Stanford University, USA and in the Heart Center Berlin-Buch. He started working in private practice since 1997.
Abstract:
We report about 7-years results of a prospective comparative study of VenaSeal®-Closure in the treatment of 2250 saphenous veins in 1250 patients. The present research paper sheds light on the advantages and disadvantages and presents the 84-month results of a single-center ambulatory clinical study with prospective design. In the base, all varicose veins should be treated actively. This we can find in nearly all guidelines worldwide. Since 20 years by now, varicosis has been increasingly treated endovenously. Before this, the varicose veins were treated radically with the stripping-method, a 110 years old radical surgery method. At the start, the rather inconvenient VNUS® Closure Plus procedure and the more convenient linear laser procedure were used, and these were followed in 2006/2007 by the bipolar RFITT® catheter, the VNUS® ClosureFast system and the radial laser. Thus, in the course of the last few years, plenty of experience has been gathered with endoluminal therapy, quality criteria have been defined and standards for the different techniques have been developed. In addition, 16 years ago, far from the beaten tracks of radio wave and laser, the development of a fascinatingly simple, yet nevertheless highly effective method of sealing veins-the VenaSeal® closure technique - was initiated. After CE approval had been granted in the autumn of 2011, a number of vein centers in Germany and Europe started using the VenaSeal®-system. Today there is an approval in all countries, also in USA since 2 / 2015. The author has applied VenaSeal™ for the first time in a great saphenous vein on 1st August 2012.

Keynote: Effects of intraoperative magnesium sulphate administration on the incidence of chronic postsurgical pain in patients undergoing total knee arthroplasty
Time : 10:35- 11:10
Biography:
Sang-Hwan Do is specialized in Orthopaedic Anesthesia and has quite a few clinical experiences of using magnesium sulphate during surgeries of diverse kinds. Through his numerous publications on magnesium, he stresses the efficacies of this mineral in surgical patients, such as improvement of postoperative pain, potentiation of intraoperative neuromuscular blockade and so on. Now, he is working at Seoul National University Bundang Hospital.
Abstract:
Magnesium sulphate (MgSO4) is an effective analgesic adjuvant for acute postoperative pain. However, the effect of MgSO4 on chronic postsurgical pain (CPSP) remains unknown. We investigated this effect of MgSO4 in patients undergoing total knee arthroplasty (TKA) retrospectively. The operation was conducted by the same experienced surgeon under spinal anesthesia, unilaterally (n=355), staged bilaterally (n=489, at 1-week interval) or simultaneous bilaterally (n=31). The magnesium group received MgSO4 (50 mg/kg) over 15 min followed by a continuous infusion (15 mg/kg/h) during the operation. Medical records of a total of 875 patients [control group (n = 780) and the magnesium group (n = 95)] for 6 years (2012~2017) were reviewed retrospectively. In case of insufficient records, telephone interview was added. The incidences of CPSP at postoperative one year were compared between the two groups. The incidence of CPSP at one year after TKA in the magnesium group (7.4%) was significantly lower than that of the control group (16.4%) (P = 0.031). Intraoperative administration of MgSO4 was effective for preventing the occurrence of CPSP after TKA

Abstract:
Telemedicine is defined as the remote delivery of health care services and clinical information using telecommunications technology. As the internet evolves and high-speed cable or satellite technology becomes more available, healthcare providers are exploring new ways to accelerate care or reach patients in remote areas. Clinicians are now applying these techniques in the field of anesthesiology. The business market for telemedicine is growing in USA and the world with new devices or applications being released almost daily. In the anesthesia literature, there are published examples of using telemedicine in ICU and preoperative clinic settings, as well as intra-operative consultations between continents. Application of this technology does, however, create concerns over medical licensure, potential liability, and reimbursement challenges.

Abstract:
Introduction: Health care system is an extremely risky domain as the third leading cause of death in America is medical errors. The operating theatre (OT) is recognized as a high-risk, accident prone environment where consequences of failure can be catastrophic. OT is also regarded as a complex, dynamic and tightly coupling system that can spring nasty surprise.
Multiple Case Reports: We will describe multiple cases in which various factors have led to human errors which induced anesthetic crises. The problem of morbidity and mortality from adverse events in healthcare has undergone over 15 years of intensive scrutiny and research worldwide; despite of dramatically intensified efforts to increase safety of the healthcare system and reports have suggested that safety has not improved. The adverse event rate has remained the same suggesting that our current solution to the problem is not working. We will explain an approach to counteract this defect in anesthetic care system through a multi-dimensional protective vision (MDPV) which is composed of knowledge and is the catalogue of most common anesthetic errors. Their classification and types with over emphasis on correcting cognitive errors which are thought process errors that lead to incorrect diagnoses and/or treatment. We will define anesthetic non-technical skills (ANTS) which are cognitive, mental, behavioral and interpersonal abilities that are crucial to guarantee maximum safety and reduce the risk of errors. They are expressed as art of decision making, task management, situation awareness, communication, team work and stress management. We will explain the science of high reliability organizations (HROs) which are those organizations like aviation industry and nuclear power stations that are running high risk tasks with excellent safety records. We will show the behavioral markers by which HRO teams promote safety.
Conclusion: We strongly recommend adopting (MDPV) via pre and post graduate program composed of comprehensive training in human factors and understanding the key types of cognitive errors specific to anesthesia which can be the first step towards training in metacognition de-biasing strategies and continuous education on ANTS as well as the science of HROs in addition to coordination strategies used by Crisis Resource Management (CRM). We suggest implementing a white box (WB) which is an audio/video record in the operating room to detect good performance to learn from and correct poor performance.

Abstract:
Robotic surgery has revolutionised patient management and opened newer doors for the anaesthesiologists regarding patient safety. Patient positioning and operation theatre (OT) configuration assumes unique importance for robotic surgery due to multiple factors. First and fore-most, the position cannot be changed once the robot is docked. Further, adequate surgical exposure requires extreme positioning and revamping of the existing positioning devices. In addition, there is restricted access to the patient and its antecedent problems. Last, but not the least, space restriction and protection of patient from the clashing robotic arms requires special devices and several unfavourable position modifications. Position related nerve palsies, pressure ulcers, port site necrosis, venous thrombosis and other injuries are on the rise in the recent years and appropriate measures may make it largely preventable. Extreme positioning causes physiological changes necessitating changes in ventilatory strategies and anaesthetic techniques. Our experience of providing perioperative and anaesthetic care for more than 3000 robotic surgeries (various surgical disciplines) has helped us to highlight the major positioning associated deficiencies and anaesthetic and other problems during robotic surgeries. We have also attempted to find practical solutions for the same and to define the best practices for robotic positioning using a thorough review of literature.

Title: Review and update: robotic transanal surgery (RTAS)
Biography:
Steven S Tsoraides has completed his medical degree and MPH degree from the University of Illinois, College Of Medicine at Peoria (UICOMP). After completing his Residency at UICOMP where he was also an Administrative Chief, he went on to complete a fellowship in Colorectal Surgery at Southern Illinois University, School of Medicine. He is currently an Associate Professor in Clinical Surgery and a Residency Program Director
Abstract:
As the field of surgery advances, new approaches have allowed surgeons additional flexibility to perform further interventions with minimal or no external incisions. For many years, single site access (SSA) has been used for transanal procedure and platforms allowing modified endoscopic approaches have been available. These platforms have limitations related to access, visualization, dexterity, camera control and instrumentation. Recently, surgical robotics companies have developed and introduced new technologies and platforms, which may help address some of these limitations. Comprehensive internet, open access and medical and industry conference reviews of robotic surgery platforms and technology available for use in SSA surgery were conducted and 30 articles were found using keywords robotic surgery, transanal, single site and robotic transanal surgery. A PubMed, Medline, Journals @OVID and open access search for data related to these platforms and technologies was also performed yielding 11 articles. Abstracts were reviewed for those written in the English language, leaving 40 articles which were then filtered for those pertaining to robotic surgery, transanal. 58 abstracts were found, duplicates were eliminated and the remaining 35 articles were read in their entirety by two reviewers. Several new and existing platforms are identified for use in SSA surgery for transanal surgery as well as abdominal and transoral surgery. These are reviewed, including brand, features, approved and suggested uses and potential limitations. New robotic technologies serve to enhance the ability of surgeons to perform SSA surgery. This next generation of robotic surgery technology overcomes some of the limitations of preceding endoscopic SSA surgery technology and will enhance the advancement of robotic transanal surgery, but outcomes and performance data are still limited.

Abstract:
Fractures of the proximal humerus account for about 5-7% of all fractures. The incidence is approximately 70 per 100,000 per year, but rises to 400/100.000/ year in women over 70 years old. In women ≥80 years old, the incidence is third only to fractures of the proximal femur and of the distal radius. Despite the rapid development of surgical techniques and an increasingly perfect implant, the treatment of proximal humeral fractures is a serious challenge. Firstly, this is related to the extremely complex biomechanics of this anatomical region and the action of muscles attaching to tuberosity of the proximal humerus, which, by pulling, lead to the displacement of bone fragments. Secondly, it is due to anatomical factors such as blood supply and the morphology of the articular surface. Therefore, the following questions are still relevant: who needs surgery, when to operate, what technique to use, how to reduce the risk of complications. Imaging tests and the necessary use of available fracture classifications are certainly useful in making decisions, but is reliance on these criteria a guarantee of success? And finally, which patients need fixation with plates and who require alloplasty. The question is complex. Especially when the surgeon has at his disposal: anatomical shape and fully modular prostheses-the fourth generation

Title: Management of primary graft dysfunction after heart transplantation
Biography:
Nikola Bradic is working in Department of Cardiovascular Anesthesiology and Cardiac Intensive Medicine, University Hospital Dubrava, Zagreb, Croatia for the last twenty years. He is specialist of Anesthesiology and subspecialist of Intensive Medicine. He is also Senior Lecturer in University North, Varazdin, Croatia, Department of Biomedical Sciences and has lectures in topics of anesthesiology, resuscitation and intensive medicine. Currently, he is working on several scientific projects and multicenter trials from the field of cardiac anesthesiology and care of cardiac patients in intensive medicine. Primary interests are in patients' hemodynamics, pharmacotherapy, mechanical heart support and echocardiography
Abstract:
Introduction: Approximately, 4-15% heart transplants, recipients do not survive in initial months after transplantation. The leading cause of early mortality after HTx is primary graft dysfunction (PGD) in which pathophysiology remains unknown. Between years 2013 and 2015, we had 41 heart transplantations in our institution and three of them developed signs of PGD. All of them we treated with VA ECMO combined with levosimendan in continuous infusion in early phases.
Cases: First patient, 53 years old male, with previous valve replacement and CABG surgery, became hemodynamically unstable soon after HTx in ICU despite of inotropic and vasoactive medical support. Emergency Transesophageal echocardiography (TEE) has shown dilated right atrium and akinetic right ventricle. Extracorporeal membrane oxygenation (ECMO) established immediately supported with continuous levosimendan infusion of 0.1 mcg/kg/ min. After 24 hours, levosimendan discontinued and ECMO continued for the next 5 days. In that period, TEE has shown improvement of right and left heart function and decrease of heart dimensions. Fifth day, ECMO discontinued, and several days later patient transferred on ward. Second patient, 39 years old male could not be weaned from CPB and ECMO with levosimendan started in operating room (OR). He stabilized hemodynamically, but his postoperative course was complicated with surgical bleeding and subsequent multiple revisions. Patient received levosimendan (0.1 mcg/kg/min) for 32 hours and was on ECMO for 72 hours. TEE on the postoperative day 5 showed left ventricle with normal diastolic diameter with systolic collapse and akinetic right ventricle (EFRV 15%). Despite all measures, the patient did not survive. Third patient, 47 year old male could not be weaned from CPB. TEE has shown significant dilatation of both ventricles with global hypocontractility. ECMO and levosimendan (0.1 mcg/ kg/min) were established; levosimendan was discontinued after 24 hours and ECMO discontinued on day 3 after HTx. In this period, TEE has shown improvement of contractility with EFLV 60%. At day 6 after ECMO removal, patient was discharged to the ward.
Conclusion: In case of PGD after HTx, combination of emergency ECMO and levosimendan has shown positive effect on hemodynamic parameters and recovery of heart function. Encouraging number of survival patients could be explained with small number of patients, and possibly would reach the data from other world centers, as we will inevitably have more patients with PGD complications. According to the suggestions of ISHLT consensus, usage of ECMO reduces the amount and dose of other inotropic and vasoactive drugs and improves the overall outcome. Results of other centers, suggest usage of ECMO over the other mechanical devices for heart support in PGD. Combination of ECMO with levosimendan within first 24 hours after HTx with PGD may shorten the time of ECMO and improve survival, and therefore could become standard treatment for PGD after transplantation in the future.

Title: Thoracoscopic video-assisted sympathicotomy for the treatment of hyperhidrosis: 20 years’ experience with minimally invasive technique
Biography:
Lago G has completed his Graduation from University of Padova, Italy. During his medical school he has developed interest in Plastic Surgery and before graduation he has participated in several research projects, especially in the field of tissue bioengineering. After his graduation he moved to USA, where he worked as Research Fellow at Brigham and Women’s Hospital in Boston. Later he returned to his home country and started his Residency program in Plastic and Reconstructive Surgery at the University of Parma, Italy
Abstract:
Statement of the Problem: Hyperhidrosis is a frequent disorder with an estimated prevalence of 3% in the general population. This condition carries relevant impairments in social relationships for the patients. Hyperhidrosis can affect different anatomical areas with palmar region being the most disturbing for everyday activities and social relevance. Several conservative and topical treatments are available for the patients but their efficacy is often limited and temporary. Video-assisted thoracoscopic sympathicotomy of T2 and T3 ganglia with a minimally invasive technique might represent a definitive treatment for palmar and axillary hyperhidrosis.
Methodology & Theoretical Orientation: This minimally invasive approach for thoracoscopic sympathicotomy was first described by Raposio et al., two decades ago. This single-entry thoracoscopic procedure is carried out with a specifically modified endoscope equipped with optic fiber and a wire loop for electrocautery at its distal end. Since 1995, 760 patients have been treated in our department with this surgical technique.
Findings: Out of 1520 thoracoscopic video-assisted sympathicotomy performed in the last 20 years, 1428 resulted in complete resolution of palmar hyperhidrosis. In 46 subjects, the procedure could not be completed due to the presence of vascular structures overlying sympathetic ganglia. In 6 patients symptoms relapsed after the procedure, most likely due to accessory sympathetic pathways. Only 2 patients complained of generalized compensatory hyperhidrosis.
Conclusion & Significance: Video-assisted thoracoscopic sympathicotomy represents a definitive treatment for palmar and axillary hyperhidrosis and it should be considered when conservative options failed to relieve the symptoms. This minimally invasive approach provides effective resolution for this disorder with minimal postoperative complication rate

Title: 7 years’ experience in migraine surgery with minimally invasive and endoscopic technique
Biography:
Raposio E has completed his Graduation at the University of Genoa with specialization in Plastic and Reconstructive Surgery and Hand Surgery; PhD at the University of Tromso, Norway, and is currently the Director of the Chair and Residency Program in Plastic Surgery at the University of Parma, Italy. During his academic career, he has gained international experience as Visiting Professor in several Plastic Surgery Departments, both in Europe and USA. His clinical activities are mainly focused on the surgical treatment of migraine headache and primary hyperhidrosis with minimally invasive techniques.
Abstract:
Statement of the Problem: Migraine Headache (MH) is a very common disorder affecting 1.7-4% of the world’s adult population. The first line therapy for these patients is usually a combination of conservative treatments. Despite this large variety of options available, some patients remain refractory. For such group, migraine surgery might offer a definitive solution for their medical condition. In these patients, migraine is usually caused by extracranial nerve compression due vascular, fascial or muscular structures nearby. The aim of migraine surgery is to relieve such compression at specific trigger points located in the occipital, temporal and frontal regions.
Methodology & Theoretical Orientation: From 2011, in our plastic surgery unit at the University of Parma, Italy, we performed 235 surgical procedures for migraine in patients suffering from either frontal, occipital or temporal headache. In patients with occipital and temporal migraine, nerve decompression was achieved by occipital and superficial temporal artery ligation, respectively. Vessels were previously localized by mean of portable doppler device. In patients suffering from frontal headache, we performed nerve decompression with single-entry endoscopic myotomies of procerus, corrugator and depressor supercilii muscles.
Findings: Among patient suffering from occipital migraine, 95% of them observed significant improvement of their condition, with 86% reporting complete relief. In temporal migraine, positive outcome was achieved in 83% of the patient’s m50% complete elimination and 33% partial improvement. In patient treated with endoscopic frontal myotomies, positive results were observed in 94% of the patients 32% complete elimination and 62% partial improvement.
Conclusion & Significance: Migraine is a common and debilitating condition that can be treated successfully with minimally invasive surgical procedures. Our results suggest that vascular compression is the main causative agent in occipital and temporal migraine.

Title: Novel approaches to anesthesia in electroconvulsive therapy
Biography:
Mohsen Jahandideh has graduated from Medical School from Azad University and always been passionate about Anaesthesiology. Currently, he is pursuing his career as a resident of anaesthesiology from Univesity of Medical Science
Abstract:
Electroconvulsive therapy (ECT) is a treatment used in various kinds of psychiatric disorders including depression, catatonia and manic disorders. There are a number of methods used to apply in ECT and there may be some complications including bradycardia, tachycardia and ECG changes. The contraindications for ECT include; intracranial hypertension, presence of a mass lesion in the brain, brain aneurysms, recent MI, angina, CHF and retinal detachment. The chronic use of psychiatric medications and co-existing medical situations warrant special care prior to ECT. Anesthesia is used to prevent unpleasant memories, while providing a prompt recovery. It is also used to preclude injury to bones due to abrupt muscle contractions during ECT. There have traditionally been various methods for providing pre-oxygenation and anesthesia during ECT. Different kinds of anesthetic drugs and neuro muscular blocking agents have also been used in this regard. But recently there many researches has been done regarding newer methods of providing preoxygenation and also different kinds of anesthetics used alone or in combination with each other that challenge the traditional methods of pre-oxygenation and anesthesia and can create better clinical results with less complications. In addition, different combinations of neuromuscular blocking agents have been studied in ECT which have yielded promising results in ECT and can reduce unwanted complications of traditional neuromuscular blocking agents. It is important for anesthesiologists to be familiar with these new methods in order to provide the best possible options for patients who require ECT in order to increase clinical results and decrease adverse complications of this procedure. We have reviewed a number of most recent studies in this regard. Although, many studies have been undertaken to improve anesthetic care furring ECT and lower the incidence of complications, there are still many questions that need to be addressed and more studies should be done to answer such questions and provide a higher standard of care for anesthesia during ECT

Title: Surgical management and outcome of complex bile duct injury after laparoscopic cholecystectomy
Biography:
Karzan Seerwan Abdullah finished his medical school in 2001 in University of Sulaimani medical college. He completed his Doctoral degree and training in General Surgery in different surgical centers in Iraq as a candidate of Iraqi council for medical specialization in 2008. He completed his fellowship training in Hepatobiliary surgery and liver transplantation at Apollo transplant institute and CLBS in Delhi in 2012. Currently, he is a teacher in Sualimani medical school and Kurdistan Board of GI surgery. His area of interest is management of bile duct injury and pancreatic cystic lesions and he has many publications in local and international journals
Abstract:
Background: There are many causes of bile duct injury. Iatrogenic bile duct injury, being the most common cause; Bile duct injury is one of the complex situations produced by a surgeon in apparently healthy patients and is associated with a significant rate of morbidity and a low rate of mortality. It needs multidisciplinary team approach between surgeons, radiologist and endoscopist. It offers better chances for an initial diagnosis, treatment options, management and follow-up of complications for the patient. We considered complex injuries: 1) injuries that involve the confluence; 2) injuries in which repair attempts have failed; 3) any bile duct injury associated with a vascular injury; 4) or any biliary injury in association with portal hypertension or secondary biliary cirrhosis. The present review is an evaluation of our experience in the treatment of these complex biliary injuries.
Objectives: To review surgical management of complex bile duct injury, review morbidity and mortality following surgical repair.
Method: We retrospectively analyzed surgical management and outcome of complex biliary injuries following cholecystectomy in 29 patients diagnosed intraoperatively following cholecystectomy or referred post operatively to our center in Sulaymaniyah governorate from January 2013 to March 2018.
Result: During the study period we have managed 59 cases of bile duct injury which they have referred to our center or consulted during cholecystectomy. Twenty nine patients were selected according to our selection criteria. Nineteen patients were female (65.5%). 21 patients with confluence injury, 5 patients with previous attempt by general surgeon, 2 patients with vascular injury and one patient with portal hypertension. In 27 patients, we performed mucosa to mucosa anastomosis between hepatic ducts and Roux-en-Y loop of jejunum. In 2 patients we performed portojejunostomy as a salvage procedure. Six patients developed stricture within 6 months for which we performed re-do anastomosis. We referred 3 patients for liver transplantation. Two patients died within 10 days of surgery because of sepsis. Both patients of porto-eneterostomy developed stricture and subsequent biliary cirrhosis.
Conclusion: Complex bile duct injury has bad prognosis and affect quality and quantity of life of the patients. The proximal the injury worse the prognosis; Porto-enterostomy has very bad outcome.

Biography:
Yamin Zheng has completed his MD at Capital Mecial University, Beijing, China. Currently, he works as a Surgeon and a Professor. He has published more than eight papers in SCI journals as first author.
Abstract:
Nonmetal clip were applied to ligate cystic duct and gall bladder vessels as an alternation for metal clip in cholecystectomy (LC) and laparoscopic bile duct exploration (LCBDE). This study aims to explore nonmetal clip migration cases after LC or LCBDE and make literature review. This study reported seven cases of nonmetal clip migration into the gastrointestinal tract or bile duct. Combined with previous literature, it was discussed about the possible risk factors, clinical presentations, outcomes and treatment. Six cases of nonmetal clip migration after LC and LCBDE were found, including 3 cases of Hem-o-lock clips and 3 cases of absorbable clips. The incidence rate of nonmetal clip migration was 1.8% (6/326). Among all complications of 51 cases, the complication rate of clip migration was 11.8%. Four clips migration cases were found after LCBDE T-tube Drainage (66.7%) and two after Primary Closure (33.3%). Five patients with clip migration into CBD (83.3%) and two patients with clip migration into duodenum (16.7%). Five patients got clips removed one case was just observed. Literature review showed more cases about nonmetal clip migration. In conclusions, postoperative nonmetal clip migration was not rare after LC and LCBDE. Migrated clip in CBD may perform stone and lead to severe complication. We should pay more attention to correctly apply clips during LCBDE, make strict follow-up and timely treatment after clip migration.

Title: Pleth varibility index based intraoperative fluid management in head and neck free flap reconstructive surgeries
Biography:
Itee Chowdhury is Senior Consultant in the Department of Anaesthesiology at Rajiv Gandhi Cancer Institute and Research Centre New Delhi India, working as oncoanaesthetist for the last twenty years. She is also a Post Graduate guide for Diplomate of National Board (DNB) Government of India which takes keen interest in research activity. She has more than twenty publications in various anaesthesia journals. This project was conceived with the aim to find a cause of free flap failures involving Re-explorations. The results were very encouraging and benefited reconstructive surgeons at her institute.
Abstract:
Background: Head and neck reconstructive surgeries involving microvascular free tissue transfer (free flap) poses a major challenge in achieving a good cosmetic and functional outcome. Intraoperative fluid administration may be an important determining factor for a successful outcome. Static parameters like central venous pressure, mean arterial pressures, heart rate measurements for intraoperative fluid administration may not be reliable. Pleth varibility index (PVI) is a dynamic non invasive parameter for intraoperative fluid administration and can easily be obtained by pulse co-oximeter derived value. PVI enables goal directed tailor maid fluid administration preventing fluid overload thus preventing possible tissue oedema, thrombus formation and flap failure.
Purpose of this study: The purpose is to study PVI based goal directed fluid administration in these long duration specialized surgeries and compare the outcome with that of body mass index (BMI) based fluid therapy.
Methodology: A randomized prospective study on eighty patients of head and neck surgery involving free flap of four to five hour duration was conducted, one group of forty patients received fluid therapy based on body weight @ 6-8mL/ kg. Another study group of forty patients received intraoperative fluid therapy based on pulse oximetry derived PVI value ranging from 4-11. Data collected from mean arterial pressures, total crystalloid, colloids transfused urine output, thromboelastography parameters like R time, K time, alpha angle, maximum amplitude (MA) and LY3O and blood lactate levels in both groups. Results were analyzed and tested by appropriate statistical methods.
Findings: The PVI group data results showed significantly less total fluid administration, normal blood lactate levels and thromboelastography parameters within normal range compared to patients in group receiving intraoperative fluid based on body weight, which was statistically significant.
Conclusion & Significance: Pleth Variability Index may be a good alternative for goal directed intraoperative fluid management avoiding fluid overload which is non-invasive requiring minimum space in operating room. We also recommend routine thromboelastography in this group of patients at the end of surgical procedure as a guide to assess coagulation status. Adequate tissue perfusion and prevention of hypocoagulability and hypercoagulability in the study [PVI] group that may help in better microvascular free flap outcome.

Rhinoplasty is undoubtedly the most compromised of all cosmetic surgery interventions. Each patient has personal features and therefore requires a totally personalized nose, adapted to his face, and that shall be unique in all parameters. We review here a basic rhinoplasty, after we performed 4000 without pretending to exhaust possibilities: first visit, exploration, photographs, image digitalization, preoperative analytical study, hospital, operating room, anesthesia, assistants, immediate discharge, final discharge and following reviews. In brief, all things that can help all those who start in this difficult art will complement this by explaining the bases of the profiloplasty: how can we combine rhinoplasty with an elevation with a lip lift and chin reshaping with an autoimplant to obtain an excellent result.

Abstract:
Introduction & Aim: The shoulder joint is the most common dislocated joint in the human body. The aim of the study was to analyze late results of arthroscopic repair of Bankart lesions in patients with post-traumatic anterior shoulder instability.
Material & Methods: The study involved 92 patients (92 shoulders) after arthroscopic Bankart lesion repair, in patients with post-traumatic anterior shoulder instability and non-engaging Hill-Sachs lesion with a suture anchor. All patients were operated on in the lateral decubitus position using FASTak 2.8 mm, suture anchors (FASTak, Arthrex, Naples, Florida). The duration of follow-up ranged from 6 to 12.5 years (mean: 8.2 years). To assess the results of surgical treatment, the Rowe and University of California at Los Angeles rating system (UCLA) were used.
Results: Based on Rowe scores, there were 71(81.5%) excellent, 12 (12.6%) good, 5 (5.3%) satisfactory and 2 (2.1%) poor results. Rowe scores improved in a statistically significant manner (p=0.00) post-surgery, to a mean of 90 (range: 25-100). UCLA scores improved in a statistically significant manner (p=0.00), reaching post-operative levels of 12-35 (mean: 33.5). There were 9 recurrences, one case of axillary nerve praxia and one case of anchor loosening.
Conclusions: arthroscopic treatment of post-traumatic anterior shoulder instability gives good results and low recurrence rate irrespective of the number of previous dislocations, age or sex.

Title: Right heart dysfunction in cardiac surgery - prevention and management
Biography:
Nikola Bradic, MD is working on Department of Cardiovascular Anesthesiology and Cardiac Intensive Medicine, University Hospital Dubrava, Zagreb, Croatia for the last twenty years. He is specialist of anesthesiology and subspecialist of intensive medicine. He is also senior lecturer in University North, Varazdin, Croatia, Department of Biomedical Sciences, and has lectures in topics of anesthesiology, resuscitation and intensive medicine. Currently is working on several scientific projects and multicenter trials from the field of cardiac anesthesiology and care of cardiac patients in intensive medicine. Primary interests are in patients' hemodynamics, pharmacotherapy, mechanical heart support and echocardiography
Abstract:
Background: Left ventricular failure (LVF) has been established as the cause for circulatory shock for the long period of time. On the other side, the role of right ventricular failure (RVF) as the cause of circulatory shock is still insufficiently recognized in perioperative settings. Most of cases were investigated in cardiac surgery, but in non-cardiac surgery, this entity type is neglected, although, the reasons for RVF could be result from the same pathophysiology reasons. According to the newest investigations and Evaluation and Management of Right-Sided Heart Failure published in last Scientific Statement from the American Heart Association (1), this review would like to show potential causes, diagnoses and treatment for RVF.
Pathophysiology: Incidence of RVF appears in very high percentage of patients, depending of the cause. During cardiothoracic surgeries, RVF approximately in 1% after cardiotomy, 5-12% in patients undergoing heart transplantation (because of pulmonary hypertension or primary graft failure) and over the 30% in patients who need LV assist devices implantation. Further, RVF can be consequence of acute or chronic increases in pulmonary pressures, acute ischemia during surgery, disruption of left and right ventricular interdependence and cardiomyopathies as the consequence of myocarditis. In the postoperative period, acute RVF occurred in almost half of the patients, which are hemodynamically unstable. This is the result of myocardial depression after extracorporeal circulation (ECC), which is usually mild, but can exacerbate in vulnerable patients.
Clinical presentation and diagnose: Clinical presentation of acute RVF mainly varies depending on the primary cause, the occurrence of other diseases, and depends about reserve of the right heart. Right heart failure may occur suddenly during or immediately after surgery in, previously, unrecognized but compensated RHF. Diagnose is typically relies on echocardiography (transesophageal and/or transthoracic), and it is recommended to use both techniques and different views to estimate right ventricular structures and function. Pulmonary artery catheter (PAC) can give valuable information about functional status of both ventricles, pulmonary resistance, changing in trends of measured values. Usage of PAC in today practice should be reserved for the patients with previously known RVF but in combination with echocardiography is extremely useful for patients in postoperative period. Changes in electrocardiogram (ECG) in acute RVF are limited with very low sensitivity and specificity.
Treatment of RVF: The treatment of RVF can be directed on several ways. First, it is necessary to decrease RV afterload and optimization of preload. This can be accomplished with ventilation strategies, preventing of rhythm disturbances and keeping of atrioventricular synchronicity. If this measures stay without results, pharmacological treatment must be established. Inotropic support with phosphodiesterase III inhibitors and levosimendan are recommended due to their inotropic and vasodilatative (especially on pulmonary circulation), while beta agonists are recommended as the second line of inotropic support, due to their negative effects (increasing oxygen consumption and arrhythmogenic effect). If patients need support with vasoconstrictors (due to hypotension), vasopresin is recommended over norepinephrine because of its lesser vasoconstrictive on pulmonary circulation. Specific pulmonary vasodilators may be also useful to reduce RV afterload in acute RVF settings. Finally, in very difficult patients, it is recommended use of mechanical support. Extracorporeal membrane oxygenation (ECMO), both veno-venous and/or veno-arterial is recommended as the first type of mechanical support. In case of improvement lacking, long-term mechanical support with right ventricular assist device (RVAD) can be established as the temporary support, or as the bridging to transplantation.
Conclusion: Despite of much knowledge's about RVF, this complication still remains a huge problem in perioperative period in cardiac surgery patients. Recognition and treatment must be appropriate and as quick as possible, because prolonged RVF can be deleterious and increase mortality in these patients.

Abstract:
Statement of the Problem: Since no validated robotic surgical curriculum exists, a systematic approach to credentialing and training robotic surgeons using technical skills, evaluation, interventions aimed at the enhancing skill evaluation and standardizing assessment tools for certification needed to be created. Best practices include a preclinical training assessment, didactic sessions, online tutorial and hands on components utilizing simulators and dry labs and cadaveric labs. This pathway was chosen to limit a learning curve of transiting and adopting new skills. The clinical training is a deliberate practice module, focusing on a specific procedure. This allows the learning to acquire skills more efficiently by building on high volume surgeries within the learner’s clinical setting. In turn, the scalable curriculum provides additional insight to the credentialing board of an academic hospital when granting robotic privileges. To accomplish this goal, the research suggests a multi-phase iterative mixed-method design for validating a robotic surgery curriculum utilizing a proficiency-based progression of surgical skill training.
Methodology & Theoretical Orientation: A mixed-method approach is fundamental due to the available data points. A mixed-method study will provide both quantitative data points of reduction of operating room times, skill set acquirement, proficiency to mastery skill set advancement, while also obtaining expert observational data and learning cognitive load analysis. To obtain triangulation and ascertain validity, the study will employ three validated assessment tools, ranging from aerospace to medicine specific. Simulator data will provide quantitative data and cognitive load assessments will provide learner qualitative data points.
Conclusion & Significance: The evolution of a novel robotic surgical platform has been met with challenges regarding user proficiency, patient safety and emerging trends. Only by systematic reassessment of instructional methodologies, will robotics flourish for additional decades to come. Hospital systems, surgical residency programs and patients are now inquiring about surgical proficiency in robotics.

Abstract:
The excitement of the second wave of Artificial Intelligence (AI) changing our lives beyond recognition is both exciting and challenging. AI has been around for over three decades, and this new approach of artificial intelligence and due enhancements in technology, both software and hardware has resulted in the fact that human decision making is considered inferior and erratic in many fields no more in medicine. This AI technology has the potential to transform medicine to a level never seen before in terms of efficiency and accuracy but also creating insecurity and allowing the transfer of expert domain knowledge to machines. Machine learning algorithms with access to large data sets can be trained to out perform humans in many aspects. AI effectiveness in accurate diagnosis of various medical conditions and machine learning algorithms has the ability to predict patterns in medical imaging systems and has been well documented for many years. However, applying AI to all areas of medicine such as anaesthetics cannot automatically be assumed to achieve improvements beyond human experts. It is often forgotten that it is "Artificial" intelligence that is being considered. Dangers of blind assumptions and belief in AI algorithms to outperform in areas of finance and industrial sectors have lead to disastrous consequences. Examples of humans working with machine algorithms have resulted in far better performance then depending solely on AI methods by replacing human intelligence. Anaesthetics is a complex medical discipline involving much of cognitive and dexterity based work and assuming AI can easily replace experienced and knowledgeable medical practitioners is a very unreasonable expectation. This paper focuses on the complexity of both AI developments and opportunities of AI in anaesthetics for the future. It will review current advances in AI tools and hardware technologies as well as outlining how these can be used in the field of anaesthetics.
