Key result
0.5% Ropivacaine provided a significantly longer duration of analgesia compared to 0.25% Bupivacaine (747.5 vs 410.7 minutes, p<0.001) when used in ultrasound-guided TAP block for patients undergoing abdominal surgery.
Why the study?
The study evaluated the efficacy of transversus abdominis plane block with ropivacaine versus bupivacaine for postoperative analgesia in abdominal surgery.
Does 0.5% ropivacaine improve postoperative analgesia compared to 0.25% bupivacaine in patients undergoing elective lower abdominal surgeries?

Supports preferring 0.5% ropivacaine for TAP blocks in abdominal surgery; extends RCT evidence on local anesthetic selection.
Vaddi Preethi (2019) conducted an RCT in Postoperative pain after abdominal surgery (n=50). 0.5% Ropivacaine vs. 0.25% Bupivacaine (20 ml on each side) was evaluated on Mean duration of analgesia (time to first analgesic requirement in minutes) (p=<0.001). 0.5% Ropivacaine provided a significantly longer duration of analgesia compared to 0.25% Bupivacaine (747.5 vs 410.7 minutes, p<0.001) when used in ultrasound-guided TAP block for patients undergoing abdominal surgery.
