Nerve blocks for arm and hand surgery provide many advantages for patients including excellent pain control and reduction in general anesthesia-related adverse effects. Infraclavicular block is possibly the best method for performing regional anesthesia of the arm because of the consistent anesthesia of the whole arm and low incidence of serious adverse effects. Normally the anesthetist uses nerve stimulation to identify nerves supplying the forearm and hand. Recent research has indicated that to improve success from 60% to 79% two types of muscle stimulation must be sought before injection of local anesthetic. This can be time consuming, requires a significant learning process, increases complications and leaves 21% of patients with inadequate anesthesia requiring supplementation or general anesthesia. More recently practitioners have been using ultrasound imaging to direct the needle and watch local anesthetic spread around the nerves. Preliminary reports have documented that this technique is associated with much greater success than the nerve stimulation method. However a good quality study comparing the dual-endpoint infraclavicular technique with an ultrasound-guided technique has not been performed. This randomized study aims to rectify this deficiency by determining if ultrasound-guided infraclavicular block has a significantly greater success than the current standard, dual end-endpoint nerve stimulation technique.
