Abstract EN
Objectives.
The pectoral nerve block type II (PECS II block) is widely used for postoperative analgesia after breast surgery.
This study evaluated the analgesic efficacy of PECS II block in patients undergoing breast-conserving surgery (BCS) and sentinel lymph node biopsy (SNB).
Methods.
Patients were randomized to the control group (n=40) and the PECS II group (n=40).
An ultrasound-guided PECS II block was performed after induction of anesthesia.
The primary outcome measure was opioid consumption, and the secondary outcome was pain at the breast and axillary measured using the Numerical Rating Scale (NRS) 24 hours after surgery.
Opioid requirement was assessed according to tumor location.
Results.
Opioid requirement was lower in the PECS II than in the control group (43.8 ± 28.5 µg versus 77.0 ± 41.9 µg, p<0.001).
However, the frequency of rescue analgesics did not differ between these groups.
Opioid consumption in the PECS II group was significantly lower in patients with tumors in the outer area than that in patients with tumors in the inner area (32.5 ± 23.0 µg versus 58.0 ± 29.3 µg, p=0.007).
The axillary NRS was consistently lower through 24 hr in the PECS II group.
Conclusion.
Although the PECS II block seemed to reduce pain intensity and opioid requirements for 24 h after BCS and SNB, these reductions may not be clinically significant.
This trial is registered with Clinical Research Information Service KCT0002509.
