Surgeon guided serratus block, which can be performed by the surgeon in participants undergoing breast reduction surgery, may reduce the sensation of pain from the surgical field in the postoperative period. Thus, participants experience less pain in the postoperative period, consume less analgesics, and there is a decrease in related complications. The aim of this study was to evaluate the effects of the intraoperative surgeon guided serratus block applied on the analgesic consumption of the participants in the first 24 hours after surgery in participants undergoing breast reduction surgery.
