人工气道吸痰导管插入深度的临床研究

Clinical study on insertion depth of sucker tube through artificial air passage.

目的:探讨人工气道患者吸痰时吸痰管插入的有效深度。方法:将90例人工气道患者随机分成A组(浅吸痰)30例,B组(深吸痰)30例,C组(吸引管插入的深度为气管插管或气管切开导管的长度再延长1 cm)30例,观察3种方法吸痰的效果。结果:A、B两组患者痰痂堵塞、黏膜损伤出血、肺部感染、刺激性咳嗽等方面无显著性差异(P>0.05),与C组相比有显著性差异(P<0.01)。结论:人工气道患者吸痰,吸痰导管插入深度按厘米加刻度标记,以气管插管或切开导管长度再延长1 cm为宜。

Objective： To explore the effective depth of sucker tube when giving aspiration through artificial air passage. Methods： 90 patients breathing by artificial airway were divided into group A （n = 30, aspirating sputum superficially） , group B （n = 30, aspirating sputum deeply） and group C （n = 30, the depth of sucker tube exceeding treaeheal cannular lem. The effects were observed respectively. Results： The significant difference were not found in sputum scab blocking, mucous injury, pulmonary infection and irritative cough between group A and group B （P 〉0. 05 ）, but there is significant difference compared with group C （P 〈 0.01 ）. Conclusion： The proper depth is lem exceeding treachcal cannular.
