Randomized Controlled Trial
The analgesic efficacy of forearm vfversus upper arm intravenous regional anesthesia (Bier's block): A randomized controlled non-inferiority trial.
This study aimed to assess if a forearm (FA) intravenous regional anesthesia (IVRA) with a lower, less toxic, local anesthetic dosage is non-inferior to an upper arm (UA) IVRA in providing a surgical block in patients undergoing hand and wrist surgery. ⋯ We failed to demonstrate non-inferiority of forearm IVRA with a lower dosage of LA in providing a surgical block without rescue opioids and LA. Non-inferiority of no need of conversion to general anesthesia was confirmed.
