To Evaluate Analgesic Efficacy of PECS II Block and SAP Block for Post-Operative Pain Relief in Patients Undergoing Breast Surgeries.

Abstract

Background & Methods: The aim of the study is to evaluate analgesic efficacy of PECS II block and SAP block for post-operative pain relief in patients undergoing breast surgeries. Patient was placed in supine position with abduction of arm. A US probe was first placed in the infraclavicular area at lateral one‑third of the clavicle and moved laterally to locate the axillary artery and vein directly above 1st rib where pectoralis major and pectoralis minor muscles were identified.
Results: Total analgesic consumption in the Group dSAP was lower compared to that of Group dPEC which was significant statistically (p<0.05). No significant side effects or complications occurred in patients of both the groups at any point of time.
Conclusion: This study has clarified that employing an ultrasound-guided SAP block, combined with dexmedetomidine as an adjuvant alongside 0.25% levobupivacaine, results in superior postoperative analgesia compared to PEC block using the same drug. The SAP block demonstrates effective postoperative pain control, as evidenced by lower Numeric Rating Scale (NRS) scores, in contrast to PEC block in patients undergoing breast surgeries. Furthermore, the addition of dexmedetomidine (30 mcg) significantly extends the duration of postoperative analgesia.
