Effect of acute hypervolemic fluid infusion during anesthesia induction on intraoperative hemodynamics in the patients undergoing Da Vinci robot-assisted pancreatic surgery / 上海交通大学学报（医学版）

ABSTRACT

Objective: To investigate the effect of acute hypervolemic fluid infusion (AHFI) during induction of general anesthesia on intraoperative hemodynamic fluctuation in the patients undergoing pancreatic robotic surgery. Methods: Sixty patients undergoing Da Vinci robot-assisted pancreatic surgery were randomly divided into routine infusion group (control group, n=30) and AHFI group (n=30). In AHFI group, the patients were infused with 12.5 mL/kg crystalloid solution before anesthesia induction, 12.5 mL/kg colloidal solution before pneumoperitoneum, and 8 mL/(kg•h) (crystalloid solutioncolloidal solution=11) continuously after pneumoperitoneum. The patients in control group were treated with routine liquid therapy. The mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP), cardiac index (CI), stroke volume variation (SVV), and the incidence of adverse events in both groups were recorded. After operation, the exhaust time, hospitalization time and 3-month mortality of the two groups were followed up. Results: Compared with control group, the consumption of crystalloid solution, colloidal solution and both solutions in AHFI group increased (P0.05). Compared with control group, CVP increased significantly and SVV decreased significantly in AHFI group before pneumoperitoneum, after pneumoperitoneum and after postural changes (P0.05). Conclusion: Compared with conventional fluid infusion, AHFI during anesthesia induction can reduce the occurrence of adverse events in the patients undergoing Da Vinci robot-assisted pancreatic surgery. There is no significant difference in the recovery of gastrointestinal function and prognosis between the two methods.
