Application of cerebral statemonitoring technology in patients with anodynia fiberoptic bronchoscopy examination

Abstract

Objective To evaluate the sedative effect of anodynia fiberoptic bronchoscopy by using cerebral state monitor , in order to control the usage of sedatives , relieve hemodynamic fluctuations , and guide the nursing cooperation .Methods A total of 60 patients with emergency and serious diseases from October 2011 to October 2012 in emergency ICU （ EICU ） were selected and divided into two groups according to random number table method：the observation group and the control group .The sedative effect in the observation group of patients were evaluated by using cerebral state monitor , and the depth of sedation in the control group of patients were evaluated by using Ramsay Sedation Score .The dosage of propofol were adjusted according to the monitoring results in the two groups , respectively .The hemodynamics , blood gas analysis , adverse events and nursing workload were observed and compared among the patients in the two groups .Results After operation , the PO2 difference in the observation group of patients was （10.954 ±1.598） mm Hg, and significantly higher than （8.289 ±1.184） mm Hg in the control group of patients , the difference was statistically significant （ t=2.191, P〈0.05）.In the observation group, the total dosage of propofol was （9.58 ±2.472）ml, the frequency of administration was （2.05 ±0.705）, both of which were less than （12.55 ±3.096）ml and （2.55 ±0.567） in the control group, the differences were statistically significance （t=-5.750, -4.229, respectively; P〈0.05）.The time of preparation for operation in the observation group was （57.45 ±4.282） min, and longer than that of （12.45 ±3.697） min in the control group, but the time to evaluate sedation and administrate medicine in the observation group was （22.45 ±4.031） min and were significantly less than （34.45 ±7.260） min in the control group, the differences were statistically significant （t=55.177,62.320, respectively; P〈0.05）.Conclusions The application of cerebral state monitoring technology in monitoring the sedation station of fiberoptic bronchoscopy examination can quantify the anesthesia monitoring depth and reduce the dosage of sedative, also can improve the quality of nursing cooperation .
