Background Postoperative pain relief following laparoscopic cholecystectomy (LC) has been achieved using intraperitoneal (i.p.) local anesthetics. Addition of opioids can prolong postoperative analgesia. Nalbuphine is an agonist–antagonist opioid that provides analgesia without the undesirable effects of pure agonists. This study was performed to compare between postoperative analgesia of i.p. bupivacaine and bupivacaine combined with nalbuphine in patients undergoing LC. Patients and methods This study included 90 patients undergoing LC. They were randomly divided into three groups, with 30 patients each. Postoperatively, group C received 50-ml normal saline (NS), group B0 received bupivacaine 100 mg diluted with NS to 50 ml, and group BN received bupivacaine 100 mg with nalbuphine 10 mg diluted with NS to 50 ml. Pain was assessed using the visual analog scale (VAS) for 24 h, and the first analgesic request was recorded. Total analgesic consumption in 24 h, hemodynamic parameters, and adverse effects were also noted. Results Postoperative VAS values were significantly lower in group BN up to 24 h. Moreover, i.p. bupivacaine showed lower VAS values than in control group. The duration of analgesia was 11.5±0.9, 7.5±0.9, and 1.5±0.6 h in groups BN, B0, and C, respectively (P<0.001). The total analgesic consumption in 24 h. was significantly less in BN group than other groups. The hemodynamic parameters were steadier in BN group than other groups, with no significant adverse effects. Conclusion Addition of i.p. nalbuphine to bupivacaine provides superior analgesia than bupivacaine only after LC without an increase in adverse events.
