Study on the clinical features and the related factors of transient tachypnea of newborn(TTN) in term infants

Objective:To analyze the clinical features and the related factors of transient tachypnea of the newborn(TTN) in term infants.Methods:Some information of 744 term infants diagnosed with TTN at Neonatal Treatment Center of Jilin University were analyzed in the study,including the basic information,perinatal factors,clinical manifestations,accessory examination and therapy of them.Further more,they were divided into mild group and severe group depending to whether application of respiratory support,and the factors related severity of disease were analyzed.Results:Male infants were more(67.1%),and elective caesarean section was 61.8%.447 cases(60.1%) had pregnancy complications;78 cases(10.5%) with respiratory complications,the initial respiratory rate of 363 cases(48.8%) were more than 60 times per minute.The delivery mode,pregnancy complications,respiratory complications and initial respiratory rate were all significantly difference(P0.05) between the mild and severity group.Conclusion:Male gender,perinatal complications,elective caesarean section may be the risk factors of TTN.Perinatal complications,elective caesarean section and respiratory complications may be the severity related factors of TTN in term infants.Initial respiratory rate may be the predictive factor of aggravation of the disease.
