Abstract:
Objective:To evaluate the effectiveness of opioid-free anesthesia on postoperative outcomes in elderly patients following laparoscopic cholecystectomy.Methods:In this randomized controlled trial, 90 patients of either sex, aged 65-75 yr, with a body mass index of 18.5-23.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective laparoscopic cholecystectomy, were divided into 2 groups ( n=45 each) using a table of random numbers: conventional general anesthesia group (GA group) and opioid-free anesthesia group (OFA group). Anesthesia was induced with intravenous etomidate, sufentanil and cisatracurium besylate and maintained with infusion of propofol and remifentanil combined with inhalation of sevoflurane in GA group. In OFA group, bilateral ultrasound-guided transversus abdominis plane block was performed via the posterior gluteal approach (injection of 0.25% ropivacaine 20 ml respectively) before anesthesia induction, anesthesia was induced with intravenous dexmedetomidine, esketamine, etomidate and cisatracurium besylate and maintained with infusion of dexmedetomidine, esketamine and propofol combined with inhalation of sevoflurane. In both groups, mechanical ventilation was performed with a laryngeal mask airway after anesthesia induction, and ketorolac tromethamine 30 mg (for postoperative analgesia) and metoclopramide 10 mg (to prevent postoperative nausea and vomiting) were intravenously injected at the end of surgery. The intraoperative adverse cardiovascular events, emergence time, laryngeal mask airway removal time, time of postanesthesia care unit stay, and postoperative rescue analgesia, nausea and vomiting and delirium were recorded. Results:No gallbladder cardiac reflex was found during operation in either group. Compared with GA group, the incidence of intraoperative bradycardia (11% versus 22%) was significantly increased ( P<0.05), the incidence of intraoperative hypotension and postoperative nausea, vomiting and delirium (17% versus 8%, 29% versus 16%, 16% versus 4% and 18% versus 4%), and requirements for rescue analgesia and antiemetics (31% versus 7% and 13% versus 4%) were decreased ( P<0.05), the postoperative emergence time, time of laryngeal mask airway removal and time of postanesthesia care unit stay were prolonged ( P<0.05), and no statistically significant difference was found in discharge time in OFA group ( P>0.05). Conclusions:The results of this study, as a single-center, small-sample randomized controlled trial, indicate that referenced to conventional general anesthesia, opioid-free anesthesia (esketamine-dexmedetomidine based anesthesia combined with bilateral transversus abdominis plan block) can improve the short-term postoperative outcomes to a certain extent in elderly patients following laparoscopic cholecystectomy.
