Analgesic Efficacy of Combined PECS II and PIP Block Versus Thoracic Paravertebral Block Post-Mastectomy
Postoperative pain management is crucial for patients undergoing mastectomy for breast cancer. Regional analgesia techniques, such as the Thoracic Paravertebral Block (TPVB), are commonly used to reduce pain and opioid consumption; however, TPVB carries potential risks, including pneumothorax. Interfascial plane blocks, specifically the Pectoral Nerve II (PECS II) block combined with the Superficial Parasternal Intercostal Plane (PIP) block, have emerged as alternative techniques to provide comprehensive analgesia…

About this study
Postoperative pain management is crucial for patients undergoing mastectomy for breast cancer. Regional analgesia techniques, such as the Thoracic Paravertebral Block (TPVB), are commonly used to reduce pain and opioid consumption; however, TPVB carries potential risks, including pneumothorax. Interfascial plane blocks, specifically the Pectoral Nerve II (PECS II) block combined with the Superficial Parasternal Intercostal Plane (PIP) block, have emerged as alternative techniques to provide comprehensive analgesia to both the lateral and anterior chest wall. The purpose of this randomized controlled trial is to evaluate and compare the analgesic efficacy and quality of postoperative recovery between a combination of ultrasound-guided PECS II and PIP blocks versus the standard Thoracic Paravertebral Block (TPVB) in patients undergoing mastectomy with or without axillary lymph node dissection (ALND). Participants will be randomly assigned to receive either the combined PECS II and PIP block or the TPVB following general anesthesia induction. Pain scores, total opioid consumption, time to first analgesic request, quality of recovery using the QoR-15 questionnaire, and potential block-related complications will be monitored and compared over the 24-hour postoperative period.
Interventions
- Procedure: Combined PECS II and Superficial PIP Block — Ultrasound-guided regional nerve block administration consisting of PECS II block (25 mL 0.25% Bupivacaine) and superficial PIP block (10 mL 0.25% Bupivacaine) post-induction of general anesthesia prior to surgical incision.
- Procedure: Thoracic paravertebral block (TPVB) — Ultrasound-guided regional nerve block administration consisting of TPVB with 0.25% Bupivacaine (5 mL at T4 level and 5 mL at T6 level) post-induction of general anesthesia prior to surgical incision.
Primary outcomes
- Postoperative Quality of Recovery Score (QoR-15) (24 hours postoperatively)
- Postoperative Pain Severity (NRS) (Postoperative hours 0, 6, 12, and 24)
- Duration of Analgesia (Up to 24 hours postoperatively)
