Analysis on the Clinical Features and Risk Factors of Pulmonary Hemorrhage in Premature Infants
Objective To analyze the clinical features and related risk factors for pulmonary hemorrhage in premature infants.Methods 80 premature infants with pulmonary hemorrhage admitted to our hospital from October 2019 to October 2022 were selected as the pulmonary hemorrhage group,and 80 premature infants without pulmonary hemorrhage admitted to our hospital during the same period were selected as the non-pulmonary hemorrhage group.The clinical features of 80 premature infants with pulmonary hemorrhage were counted,and univariate and multivariate analysis were used to identify the related risk factors for pulmonary hemorrhage in premature infants.Results The incidences of clinical manifestations such as heart failure,hypothermia,poor response,decreased percutaneous oxygen saturation,lung rales,pale complexion,dyspnea,and cyanosis in 80 premature infants with pulmonary hemorrhage were 58.75％,43.75％,87.50％,83.75％,90.00％,65.00％,32.50％,and 87.50％,respectively.Univariate and multivariate logistic regression analysis showed that birth weight＜2 kg,infectious pneumonia,neonatal asphyxia and hyaline membrane disease were independent risk factors for pulmonary hemorrhage in premature infants(P＜0.05).Conclusions Premature infants with pulmonary hemorrhage have clinical features such as heart failure,hypothermia,poor response,decreased percutaneous oxygen saturation,lung rales,pale complexion,dyspnea,and cyanosis;The pulmonary hemorrhage in premature infants is closely related to the birth weight,infectious pneumonia,neonatal asphyxia,and pulmonary hyaline membrane disease.Clinical attention should be paid to these premature infants and targeted intervention measures should be taken to reduce the pulmonary hemorrhage.
