Axillary brachial plexus block for perioperative analgesia in 250 children

A cannula technique for axillary brachial plexus block in combination with general anaesthesia has been in use since 1994 for children undergoing surgical correction of congenital hand anomalies. During a 4-year period data were collected on 250 procedures in 185 patients of median age 3 years detailing the block technique and the intraoperative and postoperative analgesic requirements. Fifteen patients (6%) required supplemental intravenous opioid intraoperatively and this is taken as a marker of failure of the block. Ninety-five patients (38%) required postoperative codeine phosphate with a mean time to receiving codeine phosphate of 9 h. Postoperative pain was controlled in this series with oral analgesia in all but six patients who received parenteral codeine. It is proposed that a cannula technique is an effective and safe method of producing axillary brachial plexus block in children.
