Respiratory problems in preterm infants with pulmonary hemorrhage

Aim Pulmonary hemorrhage is an important cause of morbidity and mortality in premature infants. There are few studies on pulmonary hemorrhage and associated morbidities observed in premature. The aim of this study was to investigate the possible relationship between pulmonary hemorrhage and respiratory problems in premature infants. Material and method Premature infants aged 25-32 weeks who were born between January 2014 and January 2018 in the neonatal intensive care unit were included to the study. Of these premature infants, 28 were patients diagnosed as pulmonary hemorrhage and 56 were control cases with the same demographic characteristics without pulmonary hemorrhage. From the medical records of infants; clinical course characteristics such as duration of ventilation, duration of oxygen supplementation, hospital stay were detailed. The data was analyzed statistically. Results The duration of mechanical ventilation was significantly longer in the pulmonary bleeding group than in the control group (p: .001). There was a significant difference between the groups in terms of moderate and severe bronchopulmonary dysplasia (BPD) and the rate of BPD in the pulmonary hemorrhage group was higher than in the control group (17.2%-53.6%; p: .001). In addition, pulmonary hemorrhage group had significant patent ductus arteriosus (PDA) and preterm retinopathy (ROP) rate compared with control group. Discussion This study implicated that, pulmonary hemorrhage is related with respiratory morbidities in preterm infants such as BPD and prolonged respiratory support. At the same time, the other morbidities such as ROP prolonged hospitalization are higher in infants with pulmonary hemorrhage. Conclusion In the follow-up of patients with pulmonary hemorrhage, defining respiratory problems and treatment and prophylaxis of comorbid conditions may be planned sooner.

Automated summary

This study found that pulmonary hemorrhage is associated with respiratory morbidities in preterm infants, such as bronchopulmonary dysplasia and prolonged respiratory support. Infants with pulmonary hemorrhage also had higher rates of other morbidities, such as retinopathy of prematurity and prolonged hospitalization.
