Intercostal nerve block for postoperative somatic pain following surgery of thorax and upper abdomen

Abstract

From 1948 to 1973, intercostal nerve block was used 10,941 times or a total of approximately 100,000 individual nerves were blocked. Junior staff (residents) performed 95% of the blocks. The local anaesthetic solution of choice used 0.25 or 0.5% bupivacaine (Marcaine) with adrenaline. Total milligram doses of bupivacaine as high as 400 mg were employed. The duration of the blocks was 9-18 hr. No severe systemic toxic reactions occurred, e.g. disorientation, convulsions, etc. The incidence of pneumothorax was 0.073%.
