TRANSIENT RADICULAR IRRITATION AFTER SINGLE SUBARACHNOID INJECTION OFISOBARIC 2-PERCENT LIGNOCAINE FOR SPINAL-ANESTHESIA

Several cases have been reported recently in which symptoms suggestive of transient radicular irritation occurred following the use of hyper baric 5% lignocaine for spinal anaesthesia. We report on three patient s in whom we observed similar symptoms attributable to this kind of ra dicular irritation following uneventful spinal anaesthesia using isoba ric 2% lignocaine. All three patients underwent minor gynaecological p rocedure and developed burning pains in the buttocks within 24 h of su rgery. The long-term outcome was not clear for all the patients, but i n at least one the pain disappeared.
