Abstract:
Objective:To evaluate the effect of goal-directed fluid therapy (GDFT) on postoperative acute kidney injury (AKI) in elderly patients undergoing long-time abdominal surgery.Methods:The medical records from elderly patients of both sexes, aged ≥ 65 yr, with a duration of operation ≥ 8 h and American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective first abdominal surgery for gastrointestinal tumors at the Shanxi Provincial People′s Hospital from October 1, 2016 to June 30, 2022, were collected from the electronic medical record database. Patients were divided into conventional fluid therapy group (group C) and GDFT group (group G) according to whether GDFT was employed during operation. In group C, blood pressure was maintained ≥90/60 mmHg or mean arterial pressure≥65 mmHg, and urine output more than 30 ml/h. In group G, the stroke volume variation was maintained ≤13%, and cardiac index ≥2.5 L·min -1·m -2. The patient general characteristics, requirement for fluid, urine output, blood loss, requirement for vasoactive agents and abdominal hyperthermic perfusion, and operation time were recorded during operation. The development of AKI within 72 h after operation and development of other complications (pneumonia, anastomotic leakage, surgical site infection, septic shock, arrhythmia) after operation were recorded. The length of hospital stay and 30-day mortality after operation were recorded. Results:A total of 125 patients were included in this study, with 41 patients in group C and 84 patients in group G. Postoperative AKI occurred in 19 patients, with an incidence of 15.2%. Compared with group C, the requirement for colloid, total volume of fluid infused and urine volume were significantly decreased during operation, the requirement for vasoactive agents was increased during operation ( P<0.05), the risk of postoperative AKI was reduced ( OR=0.23, P<0.05), and no significant change was found in the incidence of other postoperative complications, 30-day mortality, and length of hospital stay in group G ( P>0.05). Conclusions:GDFT can reduce the risk of AKI in the elderly patients undergoing long-time abdominal surgery.
