Overview

Randomized trial demonstrates superior pain control and reduced opioid use with PECS-II versus ESP blocks in breast surgery, suggesting PECS-II provides more effective regional analgesia.

Key Points

  • To compare the postoperative analgesic efficacy of ultrasound-guided erector spinae plane (ESP) block versus pectoralis (PECS) block type II in female patients undergoing unilateral modified radical mastectomy.
  • Prospective randomized controlled trial enrolling 60 female patients scheduled for unilateral modified radical mastectomy under general anesthesia.
  • Participants were randomly assigned (1:1) to receive either a single-shot ultrasound-guided ESP block at T4 (n = 30) or a PECS-II block (n = 30), both utilizing 20 mL of 0.25% bupivacaine.
  • Recorded outcomes included total morphine consumption, analgesia duration, postoperative pain intensity scores, and the incidence of nausea and vomiting.
  • A significantly greater proportion of patients in the ESP group required rescue morphine analgesia compared to the PECS-II group (P = 0.028).
  • Total morphine consumption was significantly higher (P = 0.005) and time to first analgesia request was significantly shorter (P = 0.003) in the ESP cohort.
  • Postoperative pain intensity scores were significantly elevated in the ESP group at 1, 2, and 6 hours post-surgery compared to the PECS-II group.
