Background:To evaluate the effects of naloxone on opioid-induced side effects, the present meta-analysis was constructed.Methods:Electronic databases including PubMed, EMBASE, and CNKI (China National Knowledge Internet) were used for literature search. Studies on comparison of opioid-side effects between naloxone-treated group and placebo or normal saline-related group were included in the meta-analysis. Heterogeneity analysis was performed with Chi-square and I-2 test. Pooled analysis was based on fixed-effects model, if heterogeneity between the eligible studies was negligible (I-2<50%, P>0.05), otherwise, random-effects model was used. Sensitivity analysis was applied to assess the robustness of the results and publication bias was evaluated by Begg and Egger test.Results:Thirteen studies including 1138 patients were included in the meta-analysis. Pooled analysis indicated that naloxone could significantly reduce the occurrence of pruritus (RR [risk ratio]=0.252, 95% CI [confidence interval]=0.137-0.464), nausea (RR=0.323, 95% CI=0.245-0.428), and vomiting (RR=0.338, 95% CI=0.192-0.593) which were induced by opioids. However, naloxone did not relieve pain (standardized mean difference [SMD]=-0.052, 95% CI=-0.453 to 0.348) and somnolence (RR=0.561, 95% CI=0.287 to 1.097) in patients received opioid treatment. Additionally, there were no significant publication bias between the included studies (Begg test, P=0.602; Egger test, P=0.388).Conclusion:Addition of naloxone might act as an effective treatment for prophylaxis of opioid-induced pruritus, nausea, and vomiting in clinical practice.
