Aim: To compare the effects of transversus abdominis plane block with ropivacaine versus bupivacaine on post-operative analgesia in patients experiencing lower segment caesarean section deliveries. Material and methods: The Department of Anaesthesiology undertook this prospective, single-blind, randomised, comparative investigation. A prospective, randomised, double-blind, controlled clinical trial including 66 American Society of Anaesthesiologists (ASA) I and II patients aged 20 to 42 years old was conducted over a 6-month period. TAP block with either injection bupivacaine 0.2% 15 ml + injection dexamethasone 2mg each side in group B (n = 33) or injection ropivacaine 0.2% 15 ml + injection dexamethasone 2mg each side in group R (n = 33). Results: The demographic statistics in both groups were equivalent in our research of 66 participants. The average age was 24.22±4.28 years. Demographic characteristics, baseline pulse rate, mean arterial blood pressure, and surgical time were equivalent in both groups (Table 1). Before executing the block, baseline pulse and blood pressure were taken into account, and there was no significant difference between the two groups. The pulse rate and mean arterial blood pressure throughout the study interval were greater in Group B than in Group R, albeit both were within acceptable physiological ranges. There was a significant difference at 2 and 4 hours (p<0.05). The time for rescue analgesia in Group B was shorter than in Group R, at 6.8 h and 9.33 h, respectively. Conclusion: When administered in TAP block for postoperative analgesia in lower segment caesarean section births, 0.2% Ropivacaine offered a longer duration of analgesia than 0.2% Bupivacaine.
