Abstract: Objective To investigate the efficacy of fluid warming nursing in elderly patientsundergoing Da Vinci robotic-assisted laparoscopic radical cystectomy. Methods A total of 108 patients with bladder cancer scheduled to DaVinci robotic-assisted laparoscopic radical cystectomy were recruited and randomly divided into the control group （n=55） receiving a warming blanket （41℃） during intraoperative period and the warming group （n=53） in which all intraoperative fluids were administered via a fluid warmer （41℃）. The surgical data， body temperature， coagulation function indexes and postoperative complications were compared between the two groups. Results Compared to the control group， the warming group had significantly less intraoperative transfusion （P=0.028） and shorter hospitalization days （P<0.05）. During the entire intraoperative period （from 1 to 6 h）， body temperature was significantly higher in the warming group than in the control group. There were significant differences in preoperative fibrinogen， white blood cell， total bilirubin，intraoperative lactose， and postoperative thrombin time （TT） and platelet between the control and warming groups. Multivariate linear regression analysis demonstrated that TT was the only significant factor，suggesting that the warming group had lower TT level than the control group. Conclusion Fluid warming nursing can effectively reduce transfusion requirement and hospitalization days， maintain intraoperative normothermia and promote postoperative coagulation function.
