肺癌病人多需接受疗化、放疗、免疫抑制剂、广普抗生素等治疗;但上述治疗可使肺癌病人免疫功能低下,很易发生交叉感染,增加死亡率。为防止医源性感染,我们对100例肺癌病人的口咽部做了细菌监测,发现患者在医院获得感染为48％,病死率7％,很值得我们重视。对此应采取消毒措施。以减少患者在院感染。 Patients with lung cancer are often treated with chemotherapy, radiotherapy, immunosuppressants, and antibiotics. However, these treatments can make lung cancer patients with low immune function, are prone to cross-infection, and increase mortality. In order to prevent iatrogenic infection, we conducted bacterial surveillance on the oropharynx of 100 patients with lung cancer. We found that 48% of patients were hospitalized with an infection rate of 7%, which is worth our attention. Disinfection measures should be taken in this regard. To reduce the patient’s infection in the hospital.
