Abstract:
Objective: To investigate the changes of gastric intramucosal pH(pHi)and the association with hemody namics and oxygen utilization during cardiopulmonary bypass (CPB). Method: Adults (n=15)free of hepatic, pulmonary,and renal diseases undergoing nonemergent heart surgery,were selected. After induction of general anesthesia and endotracheal intubation,a tonometer nasogastric tube was positioned in the stomach to determine the intramucosal pH. Hemodynamics and oxygen utilization data and phi were measured at four times:30 minutes after induction of anesthesia; 15 minutes after termination of cardiopulmonary bypass; at the terminal of the surgery;and 1 day after the surgery. Result: Cardiac index significantly increased(P
