Methods The clinical data of 48 children with bronchopulmonary dysplasia in our hospital were retrospectively analyzed. Results Forty-four of 48 children improved gradually and were discharged after 21 to 33 days of hospitalization. Four children died of disease and the time of death was 10-30 days. The cause of death was pulmonary infection in 1 case, chronic respiratory failure in 2 cases, pneumothorax in 1 case . Conclusions Premature labor is a risk factor for neonatal bronchopulmonary dysplasia. Prevention should be strengthened and ventilator parameters should be set reasonably to avoid the occurrence of complications such as infection.
