ObjectivesDespite several risks, infraclavicular approaches to the brachial plexus gained popularity. The present study compared success rates, block onset times, block performance times, and frequency of adverse effects of vertical infraclavicular (VIB) and coracoid blocks (CB) in patients undergoing forearm surgery.MethodsAfter ethical committee approval and informed consent 40 patients undergoing forearm surgery were included. The brachial plexus was located using a nerve stimulator and an insulated pencil point needle. Thirty ml bupivacaine 0.5% was used for the block. The blocks were assessed every minute for the first 5 min, then every 5 min for 15 min and then every 15 min and at the end of the operation.ResultsBlock onset times of both groups were similar. Higher rates of sensory block were found in group CB at the 5th, 10th, and 15th minutes of assessment. Also higher rates of motor block were found in group CB at the 5th, 10th, 15th and 30th minutes of assessment. Time to perform block was shorter in group VIB. One patient in CB group required general anaesthesia. Except two vascular punctures in group CB no other side-effects were observed.ConclusionCoracapid block provided higher rates of sensorial and motor blocks in a similar onset time without serious complications. CB can be accepted as a safe and reliable alternative to VIB for forearm surgery.
