The efficacy of pectoral nerve block for pain control after breast augmentation: A meta-analysis of randomized controlled studies

Abstract

Background: The efficacy of pectoral nerve block for pain control remains unknown in patients undergoing breast augmentation. This meta-analysis aims to explore the analgesic efficacy of pectoral nerve block for breast augmentation.Methods: We systematically searched PubMed, Embase, Web of Science, EBSCO, and Cochrane library databases, and included randomized controlled trials reporting pectoral nerve block versus no block for breast augmentation.Results: Five randomized controlled trials were included in this meta-analysis. Compared with control group after breast augmentation, pectoral nerve block was associated with substantially reduced pain scores at 1 hour
