All randomized controlled trials (RCTs) comparing the efficacy of SAPB and INB in cardiothoracic surgery were included. Quality assessment was performed using risk of bias. All data were analyzed using Stata 15 software.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A total of 9 randomized controlled trials involving 606 patients were included, meta-analysis results indicated that no differences in 6-h pain scores [SMD\u2009=\u20090.28, 95% CI (\u22120.50, 1.06)], 12-h pain scores [SMD\u2009=\u2009\u22120.59, 95% CI (\u22121.71, 0.53)], 24-h pain scores [SMD\u2009=\u2009\u22120.07, 95% CI (\u22120.67, 0.52)], incidence of nausea and vomiting[RR\u2009=\u20090.84, 95% CI (0.27, 2.57)] and length of hospital stay [SMD\u2009=\u20090.01, 95% CI (\u22120.30, 0.32)]between the SAPB group and the INB group, However, compared with INB, SAPB may reduce total opioid consumption[SMD\u2009=\u2009\u22121.99, 95% CI (\u22123.21, \u22120.77)].<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Overall, current evidence suggests that SAPB provides analgesic efficacy comparable to INB in cardiothoracic surgery. Subgroup analyses indicated that SAPB may be associated with lower pain scores in thoracotomy procedures and reduced opioid consumption in certain clinical settings; however, these findings should be interpreted cautiously due to heterogeneity across studies. Further high-quality randomized controlled trials are warranted to confirm these results.<\/jats:p>\n <\/jats:sec>\n \n Systematic Review Registration<\/jats:title>\n \n
