【摘要】 目的：为了探讨血液病患者院内感染危险因素。方法：采用回顾性调查方法，对６８例医院感染的血液病患者进行调查分析。结果：６８例病人共发生８５起院内感染，感染部位以呼吸系统、皮肤和口腔为主。感染病原菌的为革兰阴性杆菌和真菌。革兰阴性杆菌对氨苄青霉素、头孢唑啉耐药率较高（９０．４８％，５９．０９％）。白细胞下降、化疗、激素和广谱抗生素使用是院内感染的主要危险因素。结论：为减少医院感染发生率，必须对白细胞＜２×１０９／Ｌ的病人进行保护性隔离，并合理使用抗生素治疗感染性疾病。更多还原

【Abstract】 Objective: To study the risk factors of hospital infections for patients with blood diseases. Methods:The risk factors to be analyzed on 68 Cases with retrospective study method. Results: 85 person-times of hospital infections happened among 68 cases. The majority infective positions situated on respiratory system,skin and oral cavity. The major infective bacteria were gram-negative bacillus and fungi. Further analysis shoed that gram-negative bacillus have a relative higher rates of drug resistance to ampicillin (90. 48% ) and cephazoline (59. 09% ). The main risk factors of hospital infections were the WBC decline and the usage of chemotherapy, hormones and antibiotics. Conclusions: Protective isolation to the patients with a lower WBC(<20 × 10/L) and a right usage of antibiotics while treating infective diseases were both important for reducing the hospital infective rates.更多还原
