Abstract:
Objective:To evaluate the optimization efficacy of anterior quadratus lumborum block at supra-arcuate ligament (SA-AQLB) combined with general anesthesia for laparoscopic gynecological surgery.Methods:Eighty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 28-64 yr, weighing 52-78 kg, with height of 154-166 cm, scheduled for elective laparoscopic gynecological surgery, were divided into general anesthesia group (group G, n=40) and SA-AQLB combined with general anesthesia group (group SG, n=40) using a random number table method.In group SG, bilateral SA-AQLB was performed under ultrasound guidance before anesthesia induction, and 0.4% ropivacaine 25 ml plus dexamethasone 5 mg was injected into both sides.Combined intravenous-inhalational anesthesia was applied in both groups.Patient-controlled intravenous analgesia (PCIA) with sufentanil 2 μg/kg (in 150 ml of normal saline) was performed after surgery.The PCIA pump was set up to deliver a 2 ml bolus dose with a 15-min lockout interval and background infusion at 2 ml/h.Visual analogue scale (VAS) scores for abdomen, pelvis and shoulder pain were recorded at 1, 6, 12, 24 and 48 h after operation.Flurbiprofen was used for rescue analgesia when VAS score >4.The occurrence of intraoperative cardiovascular events and amount of sufentanil used during operation were recorded.The time to first pressing the analgesia pump, effective pressing times of PCA, requirement for rescue analgesia and consumption of sufentanil after operation were recorded.The extubation time, time to first flatus after operation, first ambulation time, length of hospital stay and development of postoperative adverse reactions such as nausea and vomiting, urinary retention and respiratory depression within 48 h after operation were recorded. Results:Compared with group G, the incidence of intraoperative hypertension and tachycardia was significantly decreased, the incidence of intraoperative hypotension and bradycardia was increased, the intraoperative consumption of sufentanil was reduced, the extubation time was shortened, the time to first pressing the analgesia pump was prolonged, the effective pressing times of PCA, requirement for rescue analgesia and postoperative consumption of sufentanil were reduced, the time to first flatus, first ambulation time and length of hospital stay were shortened, VAS scores for abdomen, pelvis and shoulder pain were decreased at each time point after operation, and the incidence of nausea and vomiting, urinary retention and respiratory depression after operation was decreased in group SG ( P<0.01). Conclusions:Compared with general anesthesia, the combination of SA-AQLB and general anesthesia can reduce the opioid consumption, inhibit intraoperative stress responses and postoperative hyperalgesia and promote early postoperative recovery when used for the patients undergoing laparoscopic gynecological surgery.
