摘要
目的 :观察 2 48例慢性充血性心力衰竭 (CHF)患者肺部感染的发生率、诱因及其临床表现 ,便于更好地进行临床护理。 方法 :按NYHA心功能分级标准将患者分入Ⅲ级组、Ⅳ级组 ,统计两组肺部感染的发生率 ,并进行分析比较。 结果 :①CHF患者肺部感染发生率较高。心功能越差 ,越容易发生肺部感染 ,尤其是医院感染。②肺部感染最常见的诱因是受凉 ,其次是长期使用安眠药、糖尿病、长期卧床、住监护病房等。③肺部感染引起的咳嗽、呼吸困难、肺部音等与心衰症状相似 ,容易相互掩盖。胸片、血常规、体温、痰培养等指标单项敏感性较低 ,惟粘痰增多一项敏感性较高。 结论 :肺部感染是CHF恶化的主要因素。积极控制肺部感染 ,有利于控制心力衰竭的恶化 ,改善CHF患者的生活质量。
Objectives: To carry out clinical nursing better, we observed the incidence, inducement, and clinical presentation of pulmonary infection in 248 chronic congestive heart failure(CHF) patients. Methods:All enrolled patients were assigned to group Grade III and group Grade IV according to the NYHA Cardiac Function Grading Criteria. Pulmonary infection rates of the two groups were analyzed and compared. Results:①Incidence of pulmonary infection is high in CHF patients. The worse the heart function, the more the pulmonary infection occurred, especially for the nosocomial infection.②The most common inducement of pulmonary infection is cold, then long term hypnotic usage, diabetes mellitus, long term bed ridden, and staying in ICU. ③The symptoms caused by pulmonary infection, such as cough, dyspnea, and rales, are similar to those of heart failure and are therefore easily covered up by each other. Single indices, such as chest X ray,blood routine, temperature, and sputum culture are all of low sensitivity, except for increased phlegm only, which is highly sensitive. Conclusions:Lung infection is the major factor responsible for the deterioration of heart function. Control of pulmonary infection will conduce to the prevention of the worsening of heart failure and improvement of the life quality of CHF patients.
