[目的]研究应用口咽通气道的脑卒中病人氧驱湿化液泵入合适速度的临床效果。[方法]选取2014年9月—2016年2月入住我院神经内科应用口咽通气道脑卒中病人,并经口咽通气道应用0.45%氯化钠氧驱湿化泵入的77例,随机分为A组、B组、C组,分别以1mL/h~2mL/h、3mL/h~8mL/h、>8mL/h速度持续泵入湿化,应用3d后比较3组病人口腔黏膜情况、气道湿化效果等指标。[结果]3组病人心率差异无统计学意义(P>0.05),但B组呼吸、血氧饱和度、口腔黏膜情况、湿化效果满意、痰痂、日吸痰次数、吸痰时黏膜损伤等方面与A组、C组比较差异均有统计学意义(P<0.05)。[结论]应用口咽通气道的脑卒中病人应用0.45%氯化钠3mL/h~8mL/h的速度持续泵入是较合适的泵入速度,病人较舒适,且并发症减少。 [Objective] To study the clinical effect of oxygen-driven wetting fluid pump in stroke patients with oropharyngeal airway to proper speed. [Methods] From September 2014 to February 2016, 77 patients with oropharyngeal airway stroke admitted to our department of neurology were enrolled. Oral oro-pharyngeal airway was infused with 0.45% The rats were divided into three groups: group A, group B and group C, respectively. The rats were continuously wetted with 1mL / h ~ 2mL / h, 3mL / h ~ 8mL / h and> 8mL / h respectively. , Airway humidification and other indicators. [Results] There was no significant difference in heart rate between the three groups (P> 0.05). However, respiratory, blood oxygen saturation, oral mucosa, satisfactory wetting effect, sputum scab, daily sputum suction times, Compared with A group, C group, the differences were statistically significant (P <0.05). [Conclusion] Stroke patients using oropharyngeal airway should be pumped more slowly with 0.45% sodium chloride at the rate of 3mL / h ~ 8mL / h. The patient is more comfortable and the complication reduced.
