Patients undergoing liver transplant frequently display considerable physiological changes during the procedures as a result of both the disease process and the surgery. Haemodynamic changes occurring during liver transplantation are severe and rapid. Transoesophageal echocardiography is a minimally invasive monitor that provides real-time visual information regarding dynamic function of heart, volume status, contractility, regional wall motion. Intraoperative transoesophageal echocardiography has been standard practice for cardiac surgical procedures for more than 2 decades but its use during liver transplant is gaining popularity in recent years. Society for advancement of transplant anesthesia suggests, that transoesophageal echocardiography use in liver transplant recipients is effective and safe.1 Vital information which can be gathered from standard transoesophageal echocardiography views includes biventricular function, valvular function, volume status, pericardial abnormalities, intra-cardiac thrombus, pulmonary embolism, ventricular outflow obstruction, cardiac tamponade. 

As per our literature search, intraoperative transesophageal echocardiographic parameters have never been studied to predict the post reperfusion syndrome during living donor liver transplantation. Hence, we are conducting this study to find the intraoperative transesophageal echocardiographic parameters which can predict the post reperfusion syndrome during living donor liver transplantation.
