Comparing the controlled hypotensive effect of remifentanil in young-middle aged and elderly patients undergoing fuctional endoscopic sinus surgery / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To observe the controlled hypotensive effect of remifentanil in patients of different age groups undergoing FESS. METHODS Forty-seven ASAI-II patients were divided into two groups young-middle aged group(18～55yr,n=24)and elderly group(60～72yr,n=23). Both groups received remifentanil by continuous infusion. Their systolic blood pressures (SBP) were reduced to 30～35 % of the base values and sustained throughout surgery. SBP,diastolic blood pressure (DBP) and heart rate (HR) were monitored throughout surgery. The surgical field quality score, total dose of remifentanil and postoperative complications of each patient were recorded after the operation. RESULTS The SBP and DBP of two group were reduced to the target pressure at the beginning of the operation(P0.05). CONCLUSION Remifentanil enabled controlled hypertensions and offer superior surgical field conditions for FESS in patients of different age groups. Moreover,it was a more suitable alternative for elderly patients because HR did not increase during controlled hypotension.
