Randomized Controlled Trial Clinical Trial
Effects of sevoflurane, isoflurane and propofol infusions on post-operative recovery criteria in geriatric patients.
We compared the effects of sevoflurane, isoflurane and propofol infusions on postoperative recovery criteria in geriatric patients. Sixty patients aged > 65 years, classified as American Society of Anesthesiologists (ASA) group 1 or 2 and undergoing gynaecological or urological procedures were randomized equally into three groups. Group 1 received 1 minimum alveolar concentration (MAC) sevoflurane in a 50% O2/N2O mixture and group 2 received 1 MAC isoflurane in a 50% O2/N2O mixture. ⋯ Recovery criteria comprising the times to spontaneous eye opening, extubation, response to verbal stimuli and orientation were recorded following the discontinuation of anaesthesia. Recovery times were significantly shorter in groups 1 and 3 compared with group 2. We conclude that sevoflurane and propofol had similar effects on recovery criteria and were associated with a faster recovery than isoflurane.
