不同麻醉方法对电子支气管镜检查效果分析

目的探讨3种不同麻醉方法应用于电子支气管镜检查的临床效果。方法在我科2013年1月至6月接受普通电子支气管镜检查的l128例患者中随机抽取300例患者为研究对象，根据麻醉方式的不同分为3组（A组为利多卡因咽喉喷雾法＋氧气雾化吸人法，B组为利多卡因咽喉喷雾法＋利多卡因气管内吸人法，C组为丁卡因咽喉喷雾法＋利多卡因气管内吸人法），每组100例。观察记录患者一般资料、麻醉效果、检查前及检查进行i0min时患者生命体征的变化、检查过程中的不良反应、咳嗽反射、患者及操作医师的满意度等。结果C组检查前与检查进行i0min时生命体征波动最小，与A组和B组比较差异有统计学意义（P〈O．05）。检查过程中C组不良反应的咳嗽的发生率明显低于A组和B组，患者及医师操作满意度评分明显高于A组和B组（P〈O．05）。A组麻醉优良率为53％，B组优良率为73％，C组优良率为96％，C组与A、B组相比，差异有统计学意义（P〈0．05）。结论3种麻醉方法以丁卡因咽喉喷雾法＋利多卡因气管内吸人方法最优，患者舒适度和安全性最佳，不良反应最少，患者满意度最高，该方法值得临床推广应用。

Efficacy of different anesthesia methods in electrons bronchosoeopy examination

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： tidocaine throat spray and oxygen inhalation method, group B： lidocaine throat spray and lidocaine endotraeheal 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 〈20.05）. The incidence of adverse effects like cough in group C was lower than that in group A and group B, while the scores of satisfaction degree for both patients and physicians in group C were higher than those in group B and group C （ P d0.05）. 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.
