无创呼吸机治疗重度急性左心功能衰竭合并Ⅱ型呼吸功能衰竭的疗效探析

Therapeutic effect of noninvasive ventilator intervention on severe acute left ventricular failure with type Ⅱ respiratory failure

目的 :探讨用无创呼吸机治疗重度急性左心功能衰竭合并Ⅱ型呼吸功能衰竭的临床疗效。方法 :抽选四川省攀枝花市仁和区人民医院于2014年3月至2017年2月期间接诊的194例重度急性左心功能衰竭合并Ⅱ型呼吸功能衰竭患者作为研究对象。将其随机分为研究组和对照组(97例/组)。为对照组患者采用常规疗法进行治疗。在此基础上,采用无创呼吸机对研究组患者进行治疗。对比治疗前后两组患者的收缩压、舒张压、心率、呼吸频率、动脉二氧化碳分压、动脉氧分压、血p H值、血氧饱和度、左室射血分数、每搏输出量和心肌做功指数。结果 :与对照组患者相比,研究组患者治疗后其收缩压、舒张压、心率、呼吸频率、动脉二氧化碳分压和心肌做功指数均更低,其动脉氧分压、血p H值、血氧饱和度、左室射血分数和每搏输出量均更高,差异有统计学意义(P<0.05)。结论 :用无创呼吸机治疗重度急性左心功能衰竭合并Ⅱ型呼吸功能衰竭可显著改善患者的生命体征、心功能和肺功能。

Objective： To investigate the therapeutic effect of noninvasive ventilator intervention in severe acute left ventricular failure with type II respiratory failure. Methods： Select 194 cases of severe acute left ventricular failure with type II respiratory failure treated in People ‘s Hospital of Renhe District from March 2014 to February 2017 for research object. Randomly divided these cases into study group and control group（97 cases each group）.Treat control group with routine therapy,based on treating with routine therapy we treat study group with noninvasive ventilator.Compare systolic blood pressure, diastolic blood pressure,heart rate, respiratory rate, arterial carbon dioxide pressure,PaO2,p H value of blood, oxygen saturation, left ventricular ejection, stroke volume and myocardial performance index.Results： Compare with control group, systolic blood pressure, diastolic blood pressure,heart rate, respiratory rate, arterial carbon dioxide pressure and myocardial performance index are lower, but PaO2,p H value of blood, oxygen saturation, left ventricular ejection, stroke volume higher（P〈0.05）. Conclusion： Noninvasive ventilator intervention can improve cardiopulmonary function and vital signs of patients of severe acute left ventricular failure with type II respiratory failure.
