Efficacy of subcutaneous isobaric bupivacaine in postoperative cesarean section wound using Visual Analogue Scale (VAS)

Abstract

OBJECTIVE: To determine the efficacy of subcutaneous isobaric bupivacaine in postoperative cesarean section wounds as adjuvant pain therapy with NSAIDs using the Visual Analogue Scale (VAS). METHOD: An analytical study was conducted involving 140 post-cesarean patients, 70 were from group A (with isobaric bupivacaine) and 70 were from group B (without isobaric bupivacaine). RESULTS: It was determined that at 4 hours post-cesarean section, the group receiving subcutaneous isobaric bupivacaine (group A) demonstrated significant efficacy in reducing postoperative pain. Specifically, 78.57% reported no or mild pain, compared to 5.71% in group B. At 6 hours, this trend remained consistently high in patients in group A, where 68.57% reported no or mild pain, while in group B, this percentage was lower, at 2.86%. In addition, it significantly prolonged the analgesia time with a reduction in pain intensity at 4 hours post-cesarean section, with Odds Ratio of 0.0162 (95% CI: 0.0054-0.0487) and at 6 hours an Odds Ratio of 0.016 (95% CI: 0.0045-0.0572), indicating a lower probability of experiencing severe pain compared to group B. 90% of group A maintained analgesia during the 6 postoperative hours, accelerating early mobilization and postoperative comfort. CONCLUSION: Based on the Visual Analogue Scale (VAS), subcutaneous isobaric bupivacaine was highly effective at 4 and 6 hours post-cesarean section, improving early recovery.
