微量注射泵持续气道湿化临床效果观察

Observation on curative effect of syringe pump continuous airway humidification

[目的]观察气道开放后持续泵入湿化液后气道湿化的效果。[方法]将40例气道开放病人随机分为实验组和对照组各2 0例,实验组采用0.9%氯化钠50mL沐舒坦15mg配成湿化液持续泵入2 mL/h～5 mL/h。对照组采用相同方法配制的湿化液,每隔30min～60min沿套管或插管壁滴入2mL～5mL,时间为5min。观察两组吸出痰液及痰痂形成、刺激性咳嗽、气道黏膜出血等情况。[结果]实验组痰液黏度明显低于对照组(P<0.05),痰痂形成、刺激性咳嗽、气道黏膜出血发生率显著低于对照组(P<0.05)。[结论]气道开放病人气管内持续泵入湿化液可预防气道干燥和消除痰痂形成,对改善和保持病人呼吸道通畅有明显效果。

Objective：To observe the airway humidification effect of contin ued wet fluid pumped into after the airway opening. Methods： A total of 40 cases of patients with airway opening were selected and were randomly divided into experimental group and control group, 20 cases in each, experimental group patients received 50 mL of 0.9% sodium chloride and 15 mg ambroxol dubbed wet fluid continued to pump into for 2 mL/h of 5 mL/h. Control group using the same method of preparation of wet fluid,30 min- 60 min atong the casing or plug wall drip to 2 mL to 5 mL for 5 min. Then to observe sucked sputum and phlegm scab formation,irritating cough and airway mucosal bleeding. Results： sputum viscosity of the experimental group patients was significantly lower than that of the control group （P〈 0.05） ,The incidences of sputum callus formation,irritating cough,airway mucosal bleeding were significantly lower than that of the control group （P〈0. 05）. Conclusion：Airway open continuous wet fluid pumped into the patient＇s endotracheal can prevent airway drying and eliminate phlegm scab forma- tion,and have a demonstrable effect to improve and keep the patient respiratory smooth.
