Abstract：Objective To evaluate the different effects of laryngeal mask and mask ventilation during bronchoscopy in elder patients. Methods 120 old patients (ASA I-III) were divided into three group according to the table of random number as following:surface anesthesia with autonomous respiration (group I);endoscope mask ventilation (group II);laryngeal mask airway ventilation (group III). Oxygen inhalation through nasal tube in groupⅠ,group II and group III was ventilated with endoscope mask and LMA respectively ,thenwe observed whether there were adverse effects or not during the procedure. Results The adverse reactions of group I were more than other groups. Compared with the group I, variance of MAP,HR, RR, SpO2 in the groupⅡand groupⅢ had less changes, the cases with severe bucking decreased significantly, and satisfaction degree increased markedly, (P <0.01or P<0.05 ) . The incidence rate of resp iratory depression and airway obstruction in groupⅡwas higher than that in groupⅢ (P<0.05). Conclusion Endoscope mask ventilation and LMA can both be adopted in analgesia bronchoscopy for old patient. LMA under general anesthesia to transbronchial lung biopsy would control respiration according to the demand at any time.LMA has more advantage in the operation for the stable respiration and hemodynamics and less complications.
