Abstract

The effects of extradural sufentanil 50 μg were investigated in 10 normal volunteers. Eight of these were studied at a second session when adrenaline 1: 200000 was added to the sufentanil. Well-defined segmental analgesia developed rapidly after plain sufentanil and lasted approximately 3 h. Respiration was depressed for about the same period and was greatest in the first 2 h, as shown by a 15% increase in PECO2′ while the slope and VE50 of the carbon dioxide response curve were depressed by 45% and 55%, respectively. Moderate drowsiness occurred in most subjects, while other side effects of itching, nausea and urinary retention occurred less frequently and were not severe. Addition of adrenaline 1: 200 000 intensified segmental analgesia and prolonged duration to 5 h, while side effects were lessened. It is concluded that extradural sufentanil shows considerable promise for clinical use, and that the risk: benefit ratio is improved by adding adrenaline 1: 200000.
