本文对我院10年来266例小儿急性白血病患儿进行了医院感染的回顾性调查，其中96例发生了感染，感染率为36．1％，例次感染率46．6％，感染部位以呼吸道为主。提出小儿急性白血病医院感染的高低与小儿性别、白血病类型无关，与小儿年龄、住院天数有关；骨髓增生程度和粒细胞减少是发生医院感染的危险因素。医院感染的病原菌以革兰氏阴性杆菌和真菌为多。为减少医院感染的发生，应采取有效的预防措施应用对致病菌敏感的抗生素。
This retrospective study of 266 hospitalized children with pediatric acute leukemia in our hospital over the past 10 years, of which 96 cases of infection, the infection rate was 36.1%, the infection rate was 46.6%, the infection site to the respiratory tract Mainly. The level of nosocomial infection in pediatric acute leukemia is not related to the gender and type of leukemia in pediatric patients. It is related to pediatric age and hospitalization days. The degree of myeloproliferation and neutropenia are the risk factors of nosocomial infection. Pathogens in hospital infections are mostly Gram-negative bacilli and fungi. To reduce the occurrence of nosocomial infections, effective preventive measures should be taken to use antibiotics that are sensitive to pathogenic bacteria.
