Abstract
Objective To investigate the appropriate airway manage method in elderly painless fibreoptic bronchoscopy(FB)patients.Methods 60 patients scheduled for painless fibreoptic bronchoscopy were randomly divided into 3 groups,patients in group Ⅰ oxygen with nasal cannula,group Ⅱ with endoscopy facial mask and group Ⅲ double-tube laryngeal mask.Record bronchoscopy examination condition and systolic blood pressure(SBP)、diastolic blood pressure(DBP)、heart rate(HR)、pulse oximeter saturation(SpO2)just before bronchoscopy,2 min after insertion,biopsy or flushing,2 min after biopsy and leaving the operating room.The operation time,anesthesia time,SpO2 decline to 90％,85％ were also recorded.Results Patients in Group Ⅱ,Ⅲ experienced fewer intraoperative hypoxemia(Ⅰ 18; Ⅱ 16; Ⅲ 3)and operation suspension(Ⅰ 35; Ⅱ 5; Ⅲ 1,P＜0.01),the satisfaction for anesthesia was also higher than group Ⅰ(15％)(group Ⅱ 50％,P＜0.05;group Ⅲ 95％,P＜0.01).Conclusion Application of endoscopy facial mask,especially laryngeal mask in elderly painless fibreoptic bronchoscopy patients can reduce the incidence of intraoperative hypoxia,increase anesthesia satisfaction without increasing the anesthesia time. Key words: Laryngeal mask; Fiberoptic bronchoscopy; Anesthesia
