Long-label pulmonary form analysis among them groups
Comparison of serum 25-(OH)D levels between the BPD and non-BPD groups. (A) Serum 25-(OH)D level at birth; (B) serum 25-(OH)D level at 6 months after 40 weeks of corrected gestational age. ****, P<0.0001. BPD, bronchopulmonary dysplasia.
On pulmonary function tests, we found that long-term infants in the BPD group had significantly increased RR and considerably lower VT, TI/TE, TPEF/TE, and TEF 25% compared to those in the non-BPD group, and the differences were statistically significant (P<0.05). There were no notable differences between the two groups in terms of VPEF/VE, TEF 50%, and TEF 75%. The proportion of children with lung function impairment in the BPD group was 79.7% (), which was significantly higher than the proportion of children with lung function impairment in the non-BPD group (29.9%, ). The difference was statistically significant (P<0.05) ( Table 4 ).
Logistic regression study out-of risk things on growth of BPD inside the preterm babies
Univariate regression analysis was first performed to determine whether BPD occurred as a dependent variable in logistic regression analysis. Independent variable indicators with statistical significance (P<0.05) in the analysis results were included in the multivariate analysis. Finally, the length of hospital stay, total oxygen therapy duration, neonatal pneumonia, neonatal asphyxia, and serum 25-(OH)D level at birth were identified as independent variables in the multivariate logistic regression analysis. The results showed that total oxygen therapy duration, neonatal pneumonia, neonatal asphyxia, and serum 25-(OH)D levels at birth were independent risk factors for the development of BPD in preterm infants (P<0.05, Table 5 ).

Even though BPD the most well-known big problem during the preterm infants, its right pathogenesis stays undecided at present. Fortsätt läsa ”Long-label pulmonary form analysis among them groups”
