【摘要】 目的　探讨婴幼儿重症肺炎并发呼吸衰竭的高危因素 ,为降低婴幼儿重症肺炎病死率提供理论依据。方法　对湖南省 13家县级医院儿科 2 0 0 0年 7月 1日～ 2 0 0 1年 6月 3 0日收治的567例婴幼儿重症肺炎是否并发呼吸衰竭进行前瞻性研究 ,共调查分析 16个因素。按有无呼吸衰竭两组进行单因素和多因素Logistic回归分析。结果　单因素分析显示 :佝偻病、先天性心脏病、血红蛋白、频繁感冒、营养支持疗法、季节、危重病儿评分与婴幼儿重症肺炎并发呼吸衰竭有关。多因素分析显示 :营养不良、贫血、佝偻病、频繁感冒、冬春季、危重病儿评分与婴幼儿重症肺炎并发呼吸衰竭有关。结论　营养不良、贫血、佝偻病、频繁感冒、冬春季节、危重病儿评分是婴幼儿重症肺炎并发呼吸衰竭的危险因素。更多还原

【Abstract】 Objective To investigate the risk factors for respiratory failure in infants with severe pneumonia aged 1～36 months in order to reduce the mortality of inpatients with severe pneumonia Methods Prospective study were conducted on the collected 567 inpatient infants suffering from severe pneumonia from July 1,2000 to June 30,2001 in randomized selected 13 hospitals in Hunan 17 factors were surveyed and analyzed depending on curative effect ( with respiratory failure or without respiratory failure) as variable by single logistic regression and multiple logistic regression Results Single logistic regression analysis indicated that rachitis,congenital heart disease,hemaglobulin,frequently cold,diettherapy,season,evaluation severity score were risk factors relevant to respiratory failure in severe pneumonia Multiple logistic regression analysis indicated that innutrition,hemoglobulin,rachitis,frequently cold,season,evaluation severity score were risk factors associated with respiratory failure in severe pneumonia Conclusion Innutrition,hemoglobulin,rachitis,frequently cold,season,evaluation severity score are risk factors associated with respiratory failure in severe pneumonia更多还原
