儿童反复呼吸道感染的病因学与防治研究进展

摘要

反复呼吸道感染是儿科临床常见疾病，其病因复杂。其发病主要与免疫功能低下与紊乱、病原微生物感染、不合理应用抗生素致细菌耐药、微量元素缺乏、空气颗粒物质成分变化等有关。这些因素或单独作用于机体，或联合交互刺激机体，或长期阈下刺激呼吸道，致使机体常易患病，且反复发作。究其病因，采用中西结合疗法可较好防治反复呼吸道感染。该文对其病因学和防治研究概况进行综述。%Recurrent respiratory tract infections ( RRTIs ) are common clinical diseases in peadiatrics with complex pathogeny .Etiology of RRTIS involves multiple factors , mainly including immune hypofunction and dysfunc-tion, infection of pathogenic microorganism , the bacterial drug resistance induced by unreasonable application of anti -biotics, deficiency of trace elements , the variation of particle composition of air , etc.These factors result in the body getting sickness often more easily , and disease recurring repeatedly , by acting on the body solely , or stimulating the body by combined interaction , or long term subliminal irritation of the respiratory tract .By investigating its reason , RRTIS can be prevented and treated preferably with the combination of Chinese and western therapy .This paper briefly reviews the research advances on etiology , prevention and treatment of RRTIS in children .
