Introduction: Several modalities have been used to alleviate pain after laparoscopic abdominal surgeries – like nonsteroidal anti-inflammatory drugs (NSAIDs), opioids (both intravenous and patient controlled analgesia, infiltration of local anaesthetic, thoracic epidural block and multimodal analgesia. Apart from providing post operative pain relief, regional anaesthetic techniques improve patient recovery by preventing the neuroendocrine responses to surgery and reducing the postoperative opioid requirements. Aim: To compare the efficacy of 0.2% ropivacaine and 0.25% bupivacaine when used in USG guided Transversus abdominus plane block for post operative analgesia in abdominal surgeries. Material and Methods: 50 patients scheduled for elective lower abdominal surgeries. The patients were randomly divided into two groups of 25 each- Group B receiving 0.25% bupivacaine, group R receiving 0.2% ropivacaine. Conducted in Department of Anesthesiology, Great Eastern Medical School & Hospital, Srikakulam. Result: Results showed no significant differences between the study groups in terms of age, weight and gender distributions. VAS showed significant difference between the study groups at 6 hrs and 12 hrs. The mean postoperative VAS in group B (0.25% bupivacaine) was maximum at the end of 6 hrs (4.08) whereas the mean postoperative VAS in group R (0.2% ropivacaine) was maximum at the end 12 hrs (4.0). Conclusions: Ropivacaine can be used as a safe alternative to Bupivacaine, routinely for TAP block for patients undergoing abdominal surgeries.
