Summary
Brief summary (as posted)
The goal of this study is to compare the analgesic effects of ESPB and PECS II blocks in patients undergoing BCS. The main question it aims to answer is: * Whether these two different block procedures will create a difference in postoperative pain scores. * Comparison of total opioid consumption during the 24-hour postoperative period. Our study included patients who were female, who were going to undergo elective breast-conserving surgery between March 2022 and August 2022.
