Abstract

Objective: to assess the Analgesic efficacy of single-shot ultrasound guided Pectoral Block-II and Thoracic Erector Spine Plane Block were evaluated for postoperative pain in breast surgery.

Study Design: Quasi-experimental study.

Place and Duration of Study: Combined Military Hospital, Rawalpindi Pakistan, from Mar to Aug 2022.

Methodology: We enrolled 68 female patients in this study, who were between 25-55 years of age, booked for unilateral mastectomy and classified as American Society of Anesthesiologists I and II. They were divided randomly into two groups, where Group-M (n=34) received ultrasound guided Pectoral II Block and Group-N (n=34) received ultrasound guided Erector Spine Plane Block, with 25ml of 0.25% bupivacaine used in both groups. Pain was measured postoperatively by Visual Analog Scale for pain and 1g intravenous paracetamol was given 8 hourly with rescue pain-relieving Nalbuphine used if the score was greater than 4.

Results: Postoperatively nalbuphine consumption was found to be considerably less in patients on whom ultrasound guided Pectoral II Block was given compared to Group-N, while mean analgesia requirement was found to be 0.05±0.07882 mg/kg in Group-M compared with 0.1118±0.01 mg/kg in Group-N with p-value less than 0.007, which was statistically significant.

Conclusion: Ultrasound Guided Pectoral II Block is more significantly effective in female patients for relieving pain especially after having undergone unilateral mastectomy.
