经鼻高流量吸氧装置对ARDS患者脱机拔管后再插管率的影响

The Effect of High-flow Nasal Cannulae on the Reintubation Rate in Patients with ARDS after Extubation

目的观察经鼻高流量吸氧装置(high-flow nasal cannulae,HFNC)能否降低ARDS患者脱机拔管后的再插管率。方法选取符合ARDS诊断的患者90例,按照随机数字表法分为试验组和对照组,试验组拔管脱机后应用加温加湿高流量吸氧装置给予供氧,对照组患者在脱机拔管后采用常规吸氧方式(鼻导管、面罩),所有患者的治疗方法与其他护理措施相同。比较两组患者的再插管率。结果试验组的再插管率为7. 9%(3/38),对照组则为25%(10/40),两组患者的再插管率差异有统计学意义(χ2=4. 118,P<0. 05)。结论 HFNC可以降低ARDS患者脱机拔管后的再插管率。

Objective To observe whether high-flow nasal cannulae （HFNC） can reduce the reintubation rate after offline extuba- tion in patients with ARDS. Methods 90 patients who were diagnosed with ARDS were selected as the study subject and were randomly divided into experimental group and control group. With the same treating method and nursing care, the experimental group used heating and humidifying high flow oxygen device after offline extubation while the control group was given conventional ways of oxygen inhalation after offline extubation （nasal catheter, mask）. The reintubation rate of two groups was compared. Results The reintubation rate of the experimental group was 4. 48% （3/38） and that of the control group was 25% （10/40）, with statistically significant difference （X2 =4. 118, P〈0. 05）. Conclusion HFNC can reduce the reintubation rate in patients with ARDS after extubation.
