Abstract:
Objective To evaluate the effect of controlled hypotension with nitroglycerin and esmolol in the operation of endoscopic nasal surgery.Methods 60 patients undergoing selective endoscopic nasal surgery were randomly divided into three groups averagely: control group (groupⅠ), controlled hypotension with nitroglycerin group(group Ⅱ), controlled hypotension with nitroglycerin and esmolol group (groupⅢ). Every group has 20 patients.Mean artery pressure (MAP), HR, scores of surgical field quality(SSFQ) were recorded before anaesthesia and 10,20,30,40 minutes after anaesthesia. After the operation, bleeding capacity, operation time and dosage of nitroglycerin were recorded too.Results The bleeding capacity and operation time in groupⅡ and Ⅲ was significantly less than that in groupⅠ(P
