摘要

Background

Recent studies suggest that duloxetine administration before non-laparoscopic surgery may reduce postoperative pain and analgesic requirement without increasing adverse event occurrence.

Aim

To perform a systematic review and meta-analysis of randomized controlled trials (RCTs) on preoperative administration of duloxetine versus placebo for postoperative pain relief in adults undergoing laparoscopic surgery, assessing efficacy- and safety-related outcomes.

Method

We systematically searched MEDLINE, Embase, and Cochrane Library, covering all records up to July 19, 2024. Inclusion criteria consisted of RCTs comparing preoperative administration of duloxetine versus placebo in adults undergoing laparoscopic surgery and reporting at least one outcome of interest. The random-effects model was used to estimate the mean difference (MD) and risk ratio (RR), along with their respective 95% confidence intervals (95%CIs).

Results

We included four RCTs (227 patients). Compared with placebo, duloxetine provided a statistically lower pain scores at 2 (MD − 1.04; 95%CI − 1.75, − 0.33), 4 (MD − 1.28; 95%CI − 1.77, − 0.79), 8 (MD − 1.22; 95%CI − 1.72, − 0.72), 12 (MD − 1.64; 95%CI − 2.88, − 0.41), and 24 h (MD − 1.05; 95%CI − 1.72, − 0.39) after surgery. Duloxetine also granted a statistically longer time to first analgesic requirement (MD 128.38 min; 95%CI 41.31, 215.46), compared with placebo. Additionally, the duloxetine group had a significantly lower risk of nausea/vomiting (RR 0.48; 95%CI 0.25, 0.90), while there were no significant differences between both groups for the risk of dizziness, headache, and somnolence.

Conclusion

Compared with placebo, duloxetine administration before laparoscopic surgery significantly minimized postoperative pain intensity, delayed analgesic requirement, and reduced nausea/vomiting risk.
