Abstract Objective To study the clinical and imaging features of premature infants with different degrees of bronchopulmonary dysplasia (BPD). Methods A prospective study was performed on the clinical data of 59 premature infants (gestational age <32 weeks) with BPD. Among the 59 premature infants, 37 cases had mild BPD and the other 22 cases had moderate to severe BPD. The clinical and imaging data were compared between these premature infants with different degrees of BPD. Results The durations of mechanical ventilation, oxygen therapy, antibiotic therapy, parenteral nutrition, and hospitalization in the moderate to severe group were significantly longer than those in the mild group (P<0.05). The incidence of nosocomial infection and number of times of red blood cell transfusion in the moderate to severe group were significantly higher than that in the mild group. The rates of X-ray changes, including grade I respiratory distress syndrome (1 day after birth) and hypolucency of lungs (4-10 days and ≥28 days after birth) were significantly higher in the mild group than in the moderate to severe group. The rates of X-ray changes in classical BPD stage III (4-10 days after birth) and IV (≥28 days after birth) were significantly higher in the moderate to severe group than in the mild group. Conclusions The durations of mechanical ventilation, oxygen therapy, and antibiotic therapy and the incidence of nosocomial infection are correlated with the severity of BPD. The premature infants with severer BPD need a longer duration of parenteral nutrition and more times of red blood cell transfusion and have more typical imaging changes of BPD. Imaging examination has a predictive value for the severity of BPD.
