Efficacy of different anesthesia methods in electrons bronchosocopy examination

Abstract

Objective To investigate the efficacy of the three different anesthesia methods in electron bronchoscopy examination.Methods 300 patients undergoing bronchoscopy were randomly sampled from 1 128 patients from January to June 2013.The patients were divided into three groups (group A:lidocaine throat spray and oxygen inhalation method,group B:lidocaine throat spray and lidocaine endotracheal inhalation method,group C:tetracaine throat spray and lidocaine endotracheal inhalation method).Clinical characteristics such as the changes of vital signs,adverse reactions,coughing reflex,anesthetic effect,the physician and patients' satisfaction about the bronchoscopic procedure were analyzed retrospectively.Results Compared with group A and group B,variance of visual signs 10 min after the bronchoscopic procedure in group C was the least (P ＜0.05).The incidence of adverse effects like cough in group C was lower than that in group A and group B,while tbe scores of satisfaction degree for both patients and physicians in group C were higher than those in group B and group C (P ＜0.05).The effect of anaesthesia in group C (excellent rate 96％) was better than that in gourp A (excellent rate 73％) and group B (excellent rate 53％) (P ＜0.05).Conclusions The tetracaine throat spray and lidocaine endotracheal inhalation method in bronchoscopy has excellent anesthesia effects and less adverse effects.It can greatly improve the patients' compliance and safety.
