Effects of PiCCO-guided fluid therapy on intraoperative tissue perfusion and postoperative recovery in elderly patients undergoing robot-assisted gastrointestinal surgery
Objective:To compare the effects of PiCCO-guided fluid therapy and conventional fluid therapy on intraoperative tissue perfusion and postoperative recovery of elderly patients undergoing robot-assisted gastrointestinal surgery.Methods:43 elderly patients who underwent robot-assisted gastrointestinal tumor resection under general anesthesia in Jiangsu Province Hospital of Chinese Medicine were selected and divided into two groups using random number table method.The observation group was received PiCCO-guided fluid therapy with the targeted intraoperative infusion.The control group was guided by routine strategy to maintain intraoperative infusion.The infusion rate was adjusted according to the intraoperative infusion target,and vasoactive drugs were used to maintain hemodynamic stability if necessary.The tissue perfusion indicators at different time points during surgery in the two groups of patients were compared.The time to first flatus and defecation after surgery,time to starting liquid diet,incidence of PONV,length of hospital stay,and postoperative QoR-15 score of the two groups of patients were recorded.Results:Compared with the control group,the intraoperative infusion volume in the observation group decreased,HR decreased and MAP increased 1 hour after pneumoperitoneum(T2),ELWI and aLac decreased 5 minutes after ending pneumoperitoneum to start open surgery(T3)(P<0.05).However,there was no statistically significant difference(P>0.05)between the two groups in terms of postoperative complications,postoperative flatus and defecation,postoperative diet,length of hospital stay,and QoR-15 scores.Conclusion:PiCCO-guided fluid therapy can effectively maintain hemodynamic stability during surgery,reduce intraoperative lung fluid,and facilitate tissue perfusion.
