Comparison of the analgesic efficacy of combined superficial and deep serratus anterior plane block versus pectoserratus plane block following modified radical mastectomy surgery.

BACKGROUND

Both the pectoserratus plane block and the combined deep and superficial serratus anterior plane block (CSAPB) are recognized as effective regional anesthesia methods for pain control. This research aims to assess the ability of two different nerve blocks to provide analgesia.

METHODS

The study included 60 patients who underwent modified radical mastectomy (MRM). Participants were allocated into separate groups: Group P (Pectoserratus Plane Block) and Group S (CSAPB). The primary outcome was the tramadol consumption, while the secondary outcome was the assessment of pain levels.

RESULTS

The median (Q1, Q3) postoperative 24-hour tramadol consumption was 60 (60,80) mg in Group P and 60 (40,60) mg in Group S. ( = 0.006) Additionally, higher NRS scores were observed in group P at 2 and 4 h.

CONCLUSIONS

In this study, we found that the CSAPB and the pectoserratus plane block provided comparable analgesic efficacy in patients undergoing MRM. This approach may serve as an effective alternative to the pectoserratus plane block.
