急性白血病患者由于疾病的性质导致体内白细胞的质和量出现不同程度异常,因此患者机体免疫功能较低下,同时,在治疗过程中应用的化疗药物、激素、抗菌药物以及免疫制剂等导致免疫功能严重降低~([1]),患者极易感染,不仅影响化疗的疗程和药物剂量的选择,也会使化疗的间隔时间延长,降低治疗有效率,影响整体疗效~([2])。分析患者医院感染的临床特点,在早期及时对感染给予一定干预和控制,能有效改善患者预后,提高远期生存率。因此,本研究对66例急性白血病合 Patients with acute leukemia due to the nature of the disease led to different levels of quality and quantity of white blood cells in vivo, so patients with low immune function, while the application of chemotherapy drugs in the course of treatment, hormones, antibiotics and immune agents and other immune function Severe reduction of ~ ([1]), the patient is extremely susceptible to infection, not only affect the choice of chemotherapy and drug dosage, but also make the interval of chemotherapy extended, reduce the treatment efficiency, affect the overall efficacy ~ ([2]). Analysis of clinical characteristics of patients with nosocomial infections in the early timely infection to give some intervention and control, can effectively improve the prognosis of patients and improve long-term survival. Therefore, this study of 66 cases of acute leukemia
