Aim: To compare the effectiveness of post caesarean section pain relief between transversus abdominis plane block and conventional parenteral opioid analgesia by comparing visual analogue pain scores. Material and methods: The current study is a prospective randomized interventional studyobservational study. The study was conducted over the period of DNB training for a period of three years. Total 100 patients of American Society of Anesthesiologists (ASA) Grade I and II aged 18 - 45 years scheduled to undergo lower segment caesarean section under spinal anesthesia were included in this study. Results: It is observed that to compare the effectiveness of post caesarean section pain relief between ultrasound guided transversus abdominis plane block and conventional parenteral opioid analgesia by comparing visual analogue pain scores and total opioid consumption in 24 hours. A total of 100 patients, 50 in each group were included. The distribution of patients according to age between the groups. The mean age of patients of TAP and CONT groups was 25.62±2.19 and 25.64±2.31 years respectively. There was no significant (p>0.05) difference in age between the groups showing comparability of the groups in terms of age. Additionally, the distribution of patients according to ASA grade between the groups. More than half patients of both TAP (74%) and CONT (72%) group had ASA grade I. Conclusion:This study was carried out to adding transversus abdominis plane block as a part of multimodal analgesia in patients undergoing caesarean section prolonged pain- free duration, decreased VAS pain scores, reduced the number of patients who required rescue analgesicamount of rescue analgesia required was much less in amount and prolonged the time to first request for analgesia.
