The effect of anesthesia approaches on fiberoptic bronchoscopy

Objective To study the safety and feasibility of fiberoptic bronchoscopy under intravenous anesthesia.Methods Sixty examiners were divided into three groups randomly.Every group had 20 examiners.Every group had different anesthesia approaches.The tradition anesthesia group(A) was examined by nasopharynx and trachea superficial anaesthesia.The basal anesthesia group was examined by intravenous fentanyl(1 μg/kg) infusion and midazolam(0.02 mg/kg) infusion group and was examined when OAA/S was degree 3.The venous anesthesia group was examined by intravenous fentanyl(1 μg/kg) infusion and propofol pumping(10～20 ml/h) to OAA/S degree 2.They were observed for MAP、HR、SpO2、RR、adverse reactions and the feeling of the examiner.Results The adverse reactions of the tradition anesthesia group were more than other groups.The adverse reactions of the basal anesthesia group were less and the changes of MAP、HR、SpO2、RR were not significant.The examiner of the venous anesthesia group were examined under a senseless situation without discomfort.Conclusions The basal and venous anesthsia for fiberoptic bronchoscopy are safe and feasible.The feeling of examiners is better than those of the traditional anesthesia group.The achievement ratio of fiberoptic bronchoscopy is higher than others.
