Brachial plexus anaesthesia for upper limb surgery: a review of eight years' experience.

1248 supraclavicular brachial plexus blocks and 665 axillary plexus blocks were administered to 1913 patients undergoing upper limb surgery. Plexus block alone was successful in 83.5%. In a further 11.4% of cases, adequate anaesthesia was obtained following augmentation by other regional or local techniques. This resulted in an overall success rate of 94.9% and general anaesthesia was required in only 5.1%. The two percutaneous approaches to the brachial plexus did not differ in their success-rates but clinically apparent pneumothorax occurred in 0.8% of supraclavicular blocks. Brachial plexus block anaesthesia is recommended as a safe and satisfactory alternative to general anaesthesia for upper limb surgery.
