“COMPARATIVE STUDY OF POSTOPERATIVE PAIN RELIEF AFTER CESAREAN SECTION WITH OR WITHOUT LOCAL BUPIVACAINE WOUND INFILTRATION

Abstract

Objective:

To compare postoperative pain relief after cesarean section with and without local bupivacaine wound infiltration.

Methodology:

This randomized controlled trial was conducted in   Department of Obstetrics & Gynaecology, Sharif Medical & Dental College, Lahore, April to 15 July 2025.   total of 200 patients undergoing cesarean section under spinal anesthesia were included and divided into two groups (100 each). Group   received 20 ml of 0.5% bupivacaine wound infiltration, while Group B received placebo. Pain was assessed using   Visual Analogue Scale (VAS) at 4 hours postoperatively. Need for analgesia, total analgesic consumption, and time to first analgesic request were recorded. Data were analyzed using SPSS version 24.

Results:

  mean pain score was significantly lower in   bupivacaine group compared to placebo (2.1 ± 0.9 vs 3.4 ± 1.2, p<0.001). Analgesia was required in 32% of patients in Group   compared to 68% in Group B (p<0.001). Mean analgesic consumption was significantly lower in   bupivacaine group (38.5 ± 45.2 mg vs 88.7 ± 79.4 mg, p<0.001). Time to first analgesic request was significantly prolonged in Group  .

Conclusion:

Local bupivacaine wound infiltration significantly reduces postoperative pain and analgesic requirements following cesarean section and should be considered as part of routine postoperative pain management
