Abstract: Objective: To evaluate the analgesic efficacy and safety of paravertebral block (PVB) versus intercostal nerve block (INB) in thoracic surgery and breast surgery. Methods: The PubMed, Web of Science, Embase and the Cochrane Library were searched up to February 2020 for all available randomized controlled trials (RCTs) that evaluated the analgesic efficacy and safety of PVB compared with INB after thoracic surgery and breast surgery. For binary variables, odds ratio (OR) and 95% confidence interval (CI) was used. For continuous variables, weighted mean difference (WMD) and 95% confidence interval (CI) were used. RevMan5. 3 and Stata/MP 14.0 were used for performing the meta-analysis. Results: A total of 9 trials including 440 patients (PVB block:222 patients; INB: 218 patients) met the inclusion criteria. In the primary outcome, there was no significant differences between the two groups with respect to postoperative visual analogue scale (VAS) at 1h (Std. MD = -0. 20; 95% CI = -1. 11to 0. 71; P = 0. 66), 2h (Std. MD = -0. 71; 95% CI = -2. 32to 0. 91; P = 0. 39), 24h (Std. MD = -0. 36; 95% CI = -0. 73 to -0. 00; P = 0. 05) and 48h (Std. MD = -0. 04; 95% CI = -0. 20 to 0. 11; P = 0. 57). However, there was significant difference in VAS of non Chinese subgroup at 1h (Std. MD = 0. 33; 95% CI = 0. 25to 0. 41; P
