Sufentanil: A Synthetic Narcotic for Total Intravenous Anaesthesia?
High-dose fentanyl anaesthesia has been reported to suppress or at least attenuate the increases in stress hormones associated with surgical stimulation (Sebel et al. 1981; Stanley et al. 1980). Sufentanil, a potent analogue of fentanyl, has more affinity for opiate receptors (Stahl et al. 1977) and a higher therapeutic index (De Castro et al. 1979), and thus may be more efficacious in blocking these hormonal responses. A recent study (Bovill et al. 1983) demonstrated that sufentanil in a dose of 15 μg/kg could not block the hormonal increases which occurred during cardiopulmonary bypass. This study was undertaken to compare the hormonal response to these drugs in the clinical setting.
