May blunt pressor responses during bronchoscopy but not dysrhythmias or ST changes; leaves open ischemic benefit in larger trials.
Does fentanyl or alfentanil prevent adverse haemodynamic responses during bronchoscopy under general anaesthesia compared to standard anaesthesia?
Pretreatment with fentanyl or alfentanil blunts the blood pressure and rate pressure product increases during bronchoscopy, but does not prevent dysrhythmias or ischemic ECG changes.
Wark et al. (1986) studied this question.
