The primary outcomes were the patient-controlled intravenous analgesia (PCIA) demand frequency within 48 hours after the operation and postoperative pain measured by a visual analog scale (VAS) at 2 h, 4 h, 8 h, 24 h, and 48 h after surgery. Secondary outcomes were the total procedure times, cumulative consumption of anesthetic drugs, duration of surgery, duration and awaking time of anesthesia, early recovery indicator and side effects.Results: The PCIA demand frequency in LAI-II group was significantly lower compared with patients in the RSB and LAI-I group (both P < 0.001). Moreover, the total procedure times in LAI-I and LAI-II group was significantly shorter than that in the RSB group (P < 0.001, respectively), but it was comparable between LAI-I and LAI-II group (P = 0.471). Though lower at 2h and 4h postoperative in LAI-II group, pain scores at each time point had no statistical differences among three groups. There were no significant differences among three groups for other outcomes as well.Conclusion: The effect of ultrasound-guided RSB and conventional local anesthetic infiltration in SILC patients were found to be similar in terms of relieving postoperative pain and promoting recovery. Incisional infiltration using a local anesthetic injection kit can significantly reduce the demand frequency of PCIA, which serves as a rescue analgesic.Keywords: laparoscopic cholecystectomy, rectus sheath block, local infiltration analgesia, recovery, pain
