Application of Sodium Bicarbonate Ringer's Solution in Laparoscopic Hepatectomy

The study was a single-center prospective randomized controlled study. A total of 100 patients undergoing laparoscopic hepatectomy under general anesthesia were randomly divided into 2 groups: Group A, sodium bicarbonate Ringer's solution group(n=50); Group B, Lactate Ringer's solution group (intraoperative crystal fluid dilatation was lactate ringer's injection, n=50); Collect patients' arterial blood gas, blood pressure, heart rate, peripheral vascular resistance, heart rate, blood vessels, the active drug usage, 5% sodium bicarbonate injection usage, inflammation factors, transaminase, creatinine, etc. with the point of preoperative (T0), during liver specimens resected(T1), after liver specimens resected(T2), and the end of surgery (T3). Then statistical analysis and observe the application prospect of sodium bicarbonate Ringer's injection in Laparoscopic hepatectomy.
