Clinical application of controlled hypotension induced by remifentanil in nasal endoscopic surgery

Objective:To evaluate the effect of continuous infusion of remifentanil on controlled hypotension in nasal endoscopic surgery.Methods:50 cases undergoing selective nasal endoscopic surgery were random-ly divided into group A(remifentanil group) and group B(sodium nitroprusside group),and the hemody-namic changes of two groups were compared.Results:There were no not significant different in the systolic blood pressure and mean arterial blood pressure between two groups(P 0.05).The heart rate of group A was significantly lower than group B(P 0.05).Conclusion: The continuous infusion of remifentanil had ideal antihypertensive effect in nasal endoscopic surgery,is feasible and safe.
