Clinical features of full-term neonates with respiratory syncytial virus pneumonia / 中国小儿急救医学

ABSTRACT

Objective To explore the clinical features of respiratory syncytial virus(RSV) pneumonia in full-term neonatal patients.Methods All 422 full-term newborns diagnosed as pneumonia in NICU of Shenzhen Children's Hospital during January 2014 to January 2015 were included in this study.They had been detected for RSV in the way of direct immunofluorescence assay.According to the detection results, they were divided into RSV positive group and RSV negative group, the clinical data in two groups were analyzed.Results Forty-five cases were RSV positive,377 cases were RSV negative.The proportion of breast feeding was 42.22％ vs.65.25％ ,the proportion of cesarean section was 20.00％ vs.76.12％ in two groups,there were significant differences between the two groups.Hospitalization time, birth weight, gestational age, the age of admission showed no difference between two groups.The incidencs of cough (100％), shormess of breath (88.89％), three depressions (48.89 ％), fine rales (66.67 ％), wheezing (22.22％) in RSV positive group were higher than those in the RSV negative group(84.88％ ,42.44％, 13.26％, 13.53％ ,3.98％ respectively), there were significant differences between the two groups.The incidences of fever, saliva, nasal showed no significant difference between the two groups.There was significant difference in the X-ray chest film performance between two groups,RSV positive group was more emhrysema(71.11％ vs.6.9％) ,and less patch shadow(88.89％ vs.93.10％).The laboratory examination of blood routine test, C-reactive protein,respiratory failure, the positive rate of sputum culture, pneumothorax, pleural effusion were without differences.Conclusion RSV is an important pathogen of full-term neonates with infectious pneumonia.Breastfeeding and eutocia can reduce the incidence of RSV infection.Cough, shortness of breath, pulmonary rales, and emphysema in X-ray were common in RSV pneumonia.
