Abstract
Background
Ultrasound-guided regional field blocks are not widely used in outpatient plastic surgeries. The efficacy of truncal blocks (PEC1 + SAP) has not been established in plastic surgery. The purpose of this study was to analyze the outcomes of these newer anesthetic techniques compared with traditional blind local anesthetic infiltration in patients undergoing breast augmentation.
Methods
This retrospective institutional review board-approved cohort study compared the outcomes of the different practices of 2 plastic surgeons at the same accredited outpatient surgery center between 2018 and 2022. Group 1 received an intraoperative blind local infiltration anesthetic. Group 2 underwent surgeon-led, intraoperative, ultrasound-guided PEC1 (Pectoralis 1) + SAP (serratus anterior plane) blocks. Patients who underwent any procedure other than primary submuscular augmentation mammoplasty were excluded from the study. The outcomes measured included operative time, opioid utilization in morphine milligram equivalents (MME), pain level at discharge, and time spent in the post anesthetic care unit (PACU).
Results
Sixty patients met the inclusion criteria for each group for a total of 120 patients. The study groups were similar to each other. Patients receiving PEC1 + SAP blocks (group 2) had significantly lower average MME requirements in the PACU (3.04 MME vs 4.52 MME, P = 0.041) and required a shorter average PACU stay (70.13 minutes vs 80.38 minutes, P = 0.008). There were no significant differences in the pain level at discharge, operative time, or implant size between the 2 groups.
Conclusions
Surgeon-led, intraoperative, ultrasound-guided PEC1 + SAP blocks significantly decreased opioid utilization in the PACU by 33% and patient time in the PACU by 13%, while achieving similar patient pain scores and operating times.
