Key result
0.15% ropivacaine achieved a significantly higher success rate of differential nerve block compared to 0.1285% ropivacaine (90% vs 50%) in patients undergoing hand or forearm surgery.

Answers are grounded in this paper and cite their sources.
A 0.15% concentration of ropivacaine provides a significantly higher success rate for differential brachial plexus block in hand and forearm surgeries compared to 0.1285% ropivacaine, with less need for rescue analgesia or conversion to general anesthesia.

Nileshwar et al. (2020) conducted an RCT in Hand or forearm surgery requiring supraclavicular brachial plexus block (n=40). 0.15% ropivacaine vs. 0.1285% ropivacaine was evaluated on Success rate of producing differential nerve block (p=0.0138). 0.15% ropivacaine achieved a significantly higher success rate of differential nerve block compared to 0.1285% ropivacaine (90% vs 50%) in patients undergoing hand or forearm surgery.
