Low volume intercostal injection. A comparative study in patients and cadavers.
This study compared the spread of 3 ml of a solution of bupivacaine-methylene blue in the intercostal space of patients and cadavers. There were 51 successful injections in each group which demonstrated in 86% of patient injections and 84% of cadaver injections that spread was confined to one intercostal space. Spread was more extensive in cadavers, probably as a result of autolysis. It would therefore still appear necessary, when low volumes of local anaesthetic are used, to block each intercostal nerve individually.
