- Abstract: Objective To explore the effect of opioid-free anesthesia(OFA)combined with quad-ratus lumborum block(QLB)in laparoscopic radical colorectal cancer resection.Methods Sventy patients were selected for undergoing laparoscopic radical colorectal cancer resection from March to December 2023,49 males and 21 females,aged 18-75 years,BM1 18.5-28.0 kg/m2,ASA physical status Ⅱ or Ⅲ.The patients were divided into two groups using random number table method:the OFA group(group OFA)and the conventional opioid anesthesia group(group OA),35 patients in each group.Group OFA underwent bi-lateral posterior QLB under ultrasound guidance before anesthesia induction(0.25％ropivacaine 30 ml on each side),and anesthesia induction and maintenance were performed using opioid-free anesthesia regimen.And group OA cannot undergo QLB,and anesthesia induction and maintenance were carried out using opioid containing regimen.The patient's HR and MAP were recorded before anesthesia induction(T0),1 minute after endotracheal intubation(T1),before pneumoperitoneum establishment(T2),1 minute after pneumo-peritoneum establishment(T3),1 hour after surgery(T4),the end of surgery(T5),and leaving the oper-ating room(T6).The time from the patient's anesthetic discontinuation to extubation,the length of stay in the PACU,and the Steward and VAS pain scores when the patient leaves the operating room,which were recorded.NRS scores at rest and in the motor state 6,12,24,and 48 hours after surgery,time to first ex-haust,time to first ambulation,and length of postoperative hospital stay,effective PCIA pressing times and use of additional analgesic drugs within 48 hours after the operation,and postoperative adverse reactions(nausea,vomiting,hallucinations)were also recorded.Results Compared with T0,the MAP of the two groups decreased significantly at T1,T2,T4,and T5(P＜0.05),the HR in group OFA increased signifi-cantly at T1 and slowed down at T4 and T5(P＜0.05),and the HR in group OA decreased significantly at T1-T5(P＜0.05).Compared with group OA,the HR in group OFA increased significantly at T1-T3,and the MAP increased significantly at T1(P＜0.05).Compared with group OA,the extubation time and PACU residence time were significantly delayed(P＜0.05),and the Steward score when leaving the oper-ating room was significantly lower in group OFA(P＜0.05).Compared with group OA,NRS score was sig-nificantly deceased 6,12,24,and 48 hours after the surgery(P＜0.05),time to first exhaust,time to first ambulation,and length of postoperative hospital stay were significantly shartened(P＜0.05),and ef-fective PCIA pressing times and additional analgesia times were significantly decreased(P＜0.05),inci-dence of intraoperative hypotensionand postoperative nausea and vomiting(P＜0.05).Conclusion OFA combined with QLB can safely and effectively complete laparoscopic radical colorectal cancer surgery.Pa-tients with such anesthetic methods are hemodynamically more stable during anesthesia induction and intrao-peratively.These patients have better postoperative analgesia and less need for additional analgesics,and less incidence of postoperative nausea and vomiting.This approach is more beneficial for the recovery of the patient's gastrointestinal function.
