EFFICACY OF 0.25% ROPIVACAINE VS 0.25% BUPIVACAINE IN TRANSVERSUS ABDOMINIS PLANE BLOCK FOR ANALGESIA POST CAESAREAN SECTION (original) (raw)

Background: The Transversus Abdominis Plane Block (TAPB) is a method of regional anaesthesia. After lower abdominal surgery, it produces analgesia, especially when parietal wall discomfort constitutes a significant portion of pain. By depositing local anaesthetic over the transversus abdominis muscle, it permits sensory blocking of the lower abdominal wall's skin and muscles. In a doubleblinded, prospective, randomized controlled clinical study, we assessed the effectiveness of TAPB with bupivacaine and ropivacaine for postoperative analgesia in lower segment caesarean section. Materials and Methods: TAP Block was randomly administered to 60 parturients having elective or emergency LSCS and divided into two groups. Group B-TAP Block with 0.25percent Bupivacaine 20 ml each side (n=30). Group R-TAP Block with 0.25percent Ropivacaine 20 ml each side (n=30). At the conclusion of the procedure, TAP Block was done using 20 ml of either 0.25 percent ropivacaine or 0.25 percent bupivacaine on each side. A blinded observer evaluated each patient postoperatively at 30 minutes, 2, 4, 6, 12 and 24 hours after surgery. Result: Both clinically and statistically, the outcomes in the two groups were comparable. The mean duration of analgesia was 1419.93 minutes in Group B and 1343.81 minutes in Group R, both of which had statistically significant standard deviations of ± 126.9 minutes and ± 32.18 minutes, respectively. Conclusion: When administered in a TAP Block to provide postoperative analgesia following lower segment caesarean section surgery, 0.25 percent Bupivacaine provided a comparatively longer duration of analgesia, lesser VAS Scores than Ropivacaine. Both medications have a very good safety profile. Both medications have exceptional therapeutic value in terms of dependability & potent analgesia.
