文丘里空氧混合阀联合面罩温湿化给氧在脑卒中患者的应用

Efficacy of oxygen therapy delivered through Venturi air-entrainment mask and heated humidification to patients with cerebral stroke

目的探讨文丘里空氧混合阀联合面罩持续温湿化在脑卒中患者中的应用效果。方法将60例脑卒中患者按照入院时间分为对照组与观察组各30例,对照组使用扶舒清鼻导管或面罩给氧,观察组使用文丘里空氧混合阀联合面罩温湿化给氧,观察两组血氧饱和度、痰液黏稠度、痰痂形成、痰培养结果及开放气道时间。结果观察组血氧饱和度、痰液黏稠度、痰痂形成、气道开放时间显著优于对照组,痰培养阳性率显著低于对照组(P<0.05,P<0.01)。结论文丘里空氧混合阀联合面罩湿化给氧可有效提高患者氧疗效果,湿化患者气道,缩短患者气道开放时间,降低肺部感染发生率。

Objective To investigate the efficacy of oxygen therapy delivered through a Venturi air-entrainment mask and heated hu midification to patients with cerebral stroke. Methods Totally,60 stroke patients were evenly divided into a control group, who re- ceived oxygen therapy delivered via a nasal cannula or mask, and an observation group, who received oxygen therapy delivered through a Venturi air entrainment mask and heated humidification, according to the dates of their admission. Pulse oxygen satura- tion, sputum viscosity, formation of sputum scab, results of sputum cultivation, and time to airway opening were compared be- tween the 2 groups. Results The above indicators had significant differences between the 2 groups （P〈0.05 ,P〈0.01）. Conclusion Oxygen therapy delivered through a Venturi air-entrainment mask and heated humidification can effectively improve patientsr oxy- gen saturation, humidify patientsr airway, shorten the time to airway opening, and reduce incidence rate of pulmonary infection.
