坐位与仰卧位支气管镜检查的随机对照研究

A randomized controlled trial of sitting position and supine position in bronchoscopy examination

目的旨在对不同体位的支气管镜检查进行随机对照研究。方法选取88例行支气管镜检查的患者随机分为两组。其中44例行坐位下支气管镜检查,44例行仰卧位支气管镜检查,观察两组患者检查过程中生命体征变化,检查后肺功能变化及患者,检查医生的满意度。结果坐位支气管镜检查外周血氧饱和度降低,血压升高,心率过快的发生率明显低于仰卧位,检查后30分钟两组肺功能无统计差异,坐位支气管镜组内镜医师及患者的满意度得分高于平卧位组。结论总之,支气管镜检查应在最佳条件下进行,以避免出现不必要的并发症,并提高内镜医师及患者的满意度。坐位支气管镜检查因肺活量提高,血流动力学更加稳定,咳嗽更加有力,更有利于排除痰液,患者依从性更好,因此较传统的仰卧位检查更安全,舒适,有效。

Objective To randomly control the trial of sitting position and supine position in bronchoscopy examination. Methods 88 patients undergoing bronchoscopy examination were randomly divided into two groups.There were 44 cases in each group by observing the changes of vital signs during bronchoscopy,the change of pulmonary function after procedure,and the satisfaction of doctors and patients. Results The incidence of desaturation,hypertension and tachycardia were lower in sitting position than in supine position. There was no statistical difference in lung function between the two groups 30 minutes after procedure. Endoscopists＇ and patients＇ satisfaction in the sitting position group was much better than in the supine position group. Conclusion Bronchoscopy should be performed under optimal conditions to avoid the occurrence of unwanted complications,and improve the of endoscopists＇ and patients＇ satisfaction. Compared with the traditional supine position procedure,sitting position could provide more stable hemodynamics,more powerful cough,more conducive to remove sputum,and better patient compliance.
