Regional Pain Blocks and Perioperative Pain Control in Patients Undergoing Breast Implant Removal With Capsulectomy

BACKGROUND: Demand for breast implant removal is on the rise, with more than 36,000 explants performed in 2020, an increase of 7.5% from previous years. Postoperative (PO) analgesia is an important consideration in this patient group due to scar tissue surrounding the implant and the potential for extensive dissection during capsulectomy. OBJECTIVES: The authors sought to compare perioperative pain control between three different types of ultrasound (US)-guided regional anesthetic techniques in patients undergoing implant removal with capsulectomy. METHODS: The authors reviewed all patients who received an US-guided block and underwent breast implant removal with capsulectomy at their outpatient surgical center over a 2-year period. They compared intraoperative (IO), PO opioid requirement, and patient-reported pain on the first postoperative day (POD1) between 3 different block techniques using chi-square analysis. A P-value of <.05 was considered statistically significant. RESULTS: A total of 352 patients were included. Twenty-six patients (7.4%) underwent a serratus plane (SP) block, 13 (3.7%) underwent an erector spinae combined with pectointercostal fascial plane (ES + PIFP) block, and 313 (88.9%) underwent an erector spinae combined with pectoral nerve (ES + PECS1) block. ES + PECS1 was associated with less IO and PO opioid use compared with SP and ES + PIFP (1.9% vs 19.2% vs 61.5%, P < .001 for IO, 26.8% vs 34.6% vs 38.5% PO, P < .001). The ES + PECS1 block was associated with mild pain on POD1 compared with the other 2 regional block techniques (P = .001). CONCLUSIONS: Regional pain blocks, and specifically the ES block, offer effective pain control for patients undergoing breast implant removal with capsulectomy, demonstrating high patient satisfaction in the PO period with low opioid requirements.
