A preliminary assessment of epidural chloroprocaine for day procedures.

Abstract

Twenty-five patients underwent epidural anaesthesia with a new formulation of chloroprocaine 3% (1.0-1.5 ml x 10 cm body height-1) for a variety of day procedures. The mean (range) duration of surgery was 17 (5-35) min. The mean (range) time taken to establish maximal block was 16 (15-21) min and the mean (range) time to ambulation was 78 (55-95) min after administration of chloroprocaine. Twenty-three patients experienced a decrease in systolic arterial blood pressure of up to 15% of baseline values with another two decreasing by up to 25%. Two patients complained of severe backache immediately after operation and a further 16 and four patients reported mild or moderate backache respectively. Operating conditions were excellent in all but one patient and 23 patients said they would be happy to have the same anaesthetic again.
