Abstract:
Objective:To evaluate the effect of general anesthesia under the guidance of bispectral index (BIS) on postoperative fatigue syndrome (POFS) in elderly patients undergoing laparoscopic resection of gastrointestinal tumor.Methods:A total of 90 patients of both sexes, aged 65-80 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiology physical status Ⅰ-Ⅲ, undergoing elective laparoscopic resection of gastrointestinal tumor, were divided into 3 groups ( n=30 each) using a random number table method: control group (C group), BIS value 40-49 group (B1 group), and BIS value 50-60 group (B2 group). Combined intravenous-inhalational anesthesia was used.The intraoperative BIS value was maintained at 40-49 in group B1, the intraoperative BIS value was maintained at 50-60 in group B2, and the fluctuation range of heart rate and mean arterial pressure was maintained within 20% of the baseline value during operation, and vasoactive drugs were given when necessary in group C. Patient-controlled intravenous analgesia was performed with sufentanil plus dezocine plus palonosetron after surgery, when the VAS score > 3 points, oxycodone/acetaminophen tablets 5 mg were administered orally or flurbiprofen axetil 50 mg was intravenously injected for rescue analgesia.The Christensen′s Fatigue Scale (CFS) scores were recorded at 1 day before operation and 1, 3, 7 and 30 days after operation, and the development of POFS (CFS score ≥ 6) was recorded.The intraoperative consumption of propofol, remifentanil and sufentanil was recorded.The serum C-reactive protein concentration was determined by immunoturbidimetry at 1 day before operation and 1 day after operation.The requirement for rescue analgesia within 48 h after operation was recorded.The time to the first flatus, the first ambulation time, length of hospital stay, and occurrence of fever, vomiting and delirium within 3 days after operation were recorded.The Quality of Recovery-15 (QoR-15) scores were measured at 1, 3 and 7 days after operation. Results:Compared with group C, CFS scores were significantly decreased at 1, 3 and 7 days after surgery, the incidence of POFS was decreased at 7 days after surgery, QoR-15 scores were increased at each time point after operation, the length of hospital stay was shortened, and the intraoperative consumption of propofol was reduced in B1 and B2 groups ( P<0.05). Compared with group B1, the intraoperative consumption of propofol was significantly reduced, QoR-15 scores were increased at each time point after operation ( P<0.05), and no significant change was found in CFS scores, incidence of POFS at each time point after operation, or length of hospital stay in group B2 ( P>0.05). There were no significant differences in serum C-reactive protein concentration, postoperative requirement for rescue analgesia, time to first flatus, first ambulation time, and incidence of fever, vomiting and delirium at each time point among the three groups ( P>0.05). Conclusions:General anesthesia under BIS guidance can reduce POFS and promote early postoperative recovery in elderly patients undergoing laparoscopic resection of gastrointestinal tumor.
