"Duration of Preoperative Clear Fluids Fasting in Patients Undergoing Liver Transplant"

The goal of this prospective observational study is to report the duration of preoperative clear fluids fasting in patients undergoing liver transplant. It will also learn about the relationship between the duration of preoperative clear fluids fasting and changes in hemodynamic variables and metabolic profile at various anesthesia and transplant phases. The main questions it aims to answer are: * How long liver recipient fast from clear fluids before liver transplant? * Is there any relationship between the duration of preoperative clear fluids fasting and changes in blood pressure and hear rate after the induction of anesthesia? * Is there any relationship between the duration of preoperative clear fluids fasting and blood glucose concentration, blood lactate concentration and acid base balance during anesthesia for liver transplant?
