Abstract:
Objective:To evaluate the effect of goal-directed hemodynamic management of muscle oxygen saturation (SmO 2) on the postoperative renal function in hypertensive patients undergoing laparoscopic radical gastrectomy for gastrointestinal tumors. Methods:Eighty-six essential hypertension patients, aged 18-64 yr, with body mass index ≤ 30 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, undergoing elective laparoscopic radical gastrectomy for gastrointestinal tumors under general anesthesia, were divided into 2 groups ( n=43 each) using a random number table method: routine group (group C) and SmO 2 goal-directed group (group S). The fluctuation of mean arterial pressure (MAP) and heart rate (HR) were maintained < 20% of the preoperative baseline value by adjusting infusion speed and vasoactive drugs in group C. SmO 2 was maintained not less than 70% or not less than the baseline value by evaluating cardiac output (CO), HR, stroke volume, stroke volume variation, systemic vascular resistance index and MAP and by adjusting infusion rate and vasoactive drugs in group S. SmO 2, HR, MAP, CO, cardiac index (CI), stroke volume variation and systemic vascular resistance index were recorded before anesthesia induction (T 0, baseline value), at the beginning of surgery (T 1), at 40 min after the start of pneumoperitoneum (T 2), at 5 min after the end of pneumoperitoneum (T 3), and at the end of surgery (T 4). The glomerular filtration rate was measured before surgery and at 24 h after surgery, and the occurrence of decline in postoperative acute renal function was recorded.Intraoperative hypotension, fluid input and output, postoperative tracheal extubation time, length of hospital stay, occurrence of acute kidney injury and transfer to ICU, and the Quality of Recovery-15 scale score at 24 h after operation were recorded. Results:Compared with group C, SmO 2 at T 1-3 and CO and CI at T 3 were significantly increased, SVRI at T 2-4 was decreased, the intraoperative infusion volume and urine volume were increased, the glomerular filtration rate and Quality of Recovery-15 scale score were increased at 24 h after surgery, the incidence of decline in acute renal function was decreased ( P<0.05), and no significant change was found in the incidence of intraoperative hypotension, blood loss, postoperative extubation time, length of hospital stay, incidence of acute kidney injury and rate of transfer to ICU in group S ( P>0.05). Conclusions:SmO 2 goal-directed hemodynamic management can reduce the development of decline in postoperative acute renal function and improve the quality of postoperative recovery of hypertensive patients undergoing laparoscopic radical gastrectomy for gastrointestinal tumors.
