适度液体刺激在气管切开中的效果评价

Evaluation of moderate liquid stimulation in tracheotomy

目的:探讨气道液体刺激在气管切开患者气道护理中的可行性及应用效果。方法:将90例气管切开患者随机分为试验1组、试验2组和对照组,每组30例,均进行常规气道护理。试验1组用20 m L注射器将0.45%Na Cl快速注入人工气道,试验2组用灭菌注射用水快速注入人工气道,进行气道灌洗,对照组则采用常规吸痰。结果:(1)试验组患者排痰效果优于对照组患者(P<0.05);(2)试验组患者痰液黏稠度低于对照组患者(P<0.05);(3)3组的血气分析pH值、PaO_2、SaO_2及心率、呼吸频率、血压等无显著性差异(均P>0.05)。结论:在气管切开患者护理中,气道适度的液体刺激能有效降低患者痰液黏稠度、痰痂形成及堵管的发生,优于单纯的吸痰和持续气道湿化法。

Objective： To investigate the feasibility and efficacy of airway liquid stimulation in tracheotomy patients were randomly divided into experimental group 1,experimental group 2 and control group,30 cases in eachgroup . They all received routine airway nursing. 0.45% saline of 20 mL was rapidly injected ilavage in experimental group 1 while sterile water for injection was rapidly injected into artificial airway in experimental group 2 ;conventional sputum suction was applied in the control group . Results： Both experimental groups selimination and lower sputum sticky than the control group （ P 〈 0. 05 ）. There were no significant differencesSaO2, HR,RR and BP among the three groups（ P 〉 0. 05 ） . Conclusion： In the nurse of tstimulation can reduce sputum sticky,the formation of sputum scab and the occurrence of tube blockage. It is superior to simplesputum suction and continuous airway humidification.
