Abstract

A substantial component of pain experienced by patients after surgery is derived from incision made in the abdominal wall. Aim: To compare levobupivacaine 0.25% and ropivacaine 0.25% in USG guided B/L TAP block in abdominal surgeries for post operative analgesia. Methods: a Prospective randomized, comparative study conducted on 40 patients of ASA grade I and II of age 18 to 60 years undergoing elective abdominal surgery under general anaesthesia in Department of Anaesthesia, Sardar Patel Medical College and A.G. of hospitals, Bikaner during July 2022 to December 2022 after taking approval from institutional ethical committee and valid written informed consent from patient and their close relatives. At the end of the surgery USG guided TAP block was performed bilaterally in supine position via midline approach with probe placed transversely to the abdominal wall between the costal margin and iliac crest. Post operative pain will be assessed using the VAS score & was recorded at the 30th min,60 min, 90 min, 3rd hour, 6th hour, 9th hour, 12th hour, 24th hour both at rest & when coughing. Results: demographic factors like patient age, weight, gender, and ASA status were all comparable across both the study groups. Mean heart rate showed a statistically significant(p=0.0001) increase in mean heart rate (beats/min) of 90.4 ± 18.79 in Group R at 6 hrs post-operative period. Total analgesia required was significantly more in group R than group L (75±54.11 vs 120±37.69) (p=.004). The mean VAS score of both the groups did not show any significant difference except at the time period of 6 hrs and 24 hrs at rest, and mean patient satisfaction score (out of 10 ) was 8.3±0.80 in group L and 7.1±0.85 in group R (p value of 0.0001). Conclusion: levobupivacaine in present study had superior postoperative analgesia compared to ropivacaine in terms of longer duration of analgesia, with reduced analgesia requirement and better patient satisfaction in terms of pain relief.
