Abstract

Aims and Objectives: Transversus abdominis plane block is a regional anaesthesia technique. It provides analgesia after abdominal surgery particularly where parietal wall pain forms major component of pain. It allows sensory blockade of lower abdominal wall skin and muscles via local anaesthetic deposition above transverses abdominus muscle. We evaluated the efficacy of TAP block with Ropivacaine and Bupivacaine for post operative analgesia in abdominal surgery, a double blind, prospective randomized controlled trial.

Method: 50 patients undergoing elective abdominal surgeries under general anaesthesia were randomized to undergo Tap block with Ropivacaine (n=25) or Bupivacaine (n=25).Tap block was performed at the end of surgery using 20ml of 0.5% Ropivacaine or 0.25% Bupivacaine each side. Each patient was assessed postoperatively by a blinded observer at 30mins, 1, 3, 6, 12 & 24 hrs in ward.

Result: The results in both groups were comparable clinically as well as statistically.

Conclusion: we conclude that 0.5% Ropivacaine provided longer duration of analgesia than 0.25% Bupivacaine when used in TAP block for patients undergoing abdominal surgery. Both drugs have a good safety profile. Both drugs show outstanding clinical utility in terms of reliability and effective analgesia.
