高血压脑出血医院感染危险因素的研究

Study on the risk factors of hospital infection for hypertensive cere bral hemorrhage

目的 探讨高血压脑出血（ＨＣＨ）并发医院感染的危险因素。方法 选取神经内科、神经外科住院时间≥７２ｈ １９５例患者、符合医院感染诊断标准作为ＨＣＨ感染组，ＨＣＨ未感染组作为对照组。采用单因素分析与多因素分析ＨＣＨ的危险因素。结果 对３０多个可能的危险因素进行单因素分析，有２２种呈显著差异。再对这２２个变量进行非条件Ｌｏｇｉｓｔｉｃ回归分析表明：空腹血糖升高、留置胃管引起误吸、抗生素使用种类、雾化吸入为ＨＣＨ感染的危险因素。结论 ＨＣＨ感染是多因素综合作用的结果，但通过加强监护，医院感染是可以控制和减少的。

Objective To find out the risk factors of hospital infection for hypertensive cerebral hemorrhage(HCH). Methods 195 patients from Neurology Department and Neurosurgery Department whose length of stay equaled or exceeded 72 hours and who fitted in with the criterion for the diagnosis of hospital infection were chosen as the HCH infection group while HCH patients without hospital infection served as the control group. The risk factors for HCH were studied by means of both single factor analysis and multifactor analysis. Results Of more than 30 possible risk factors that were studied by means of single factor analysis, 22 manifested marked difference. Unconditional Logistic regression analysis of the 22 variables indicated that rise of fasting blood－glucose, accidental inhalation of food resulting from indwelling stomach tube, kinds of antibiotics used and spray inhalation were the risk factors of HCH infection. Conclusion HCH infection results from the synergetic action of various factors and hospital infection can be controlled and reduced by strengthening supervision.
