Abstract:
Objective:To study the complications and prognosis of extremely premature infants(EPIs) with gestational age (GA) <28 w.Methods:From January 2016 to December 2020, EPIs with GA <28 w admitted to NICU of our hospital were retrospectively studied. Clinical data of the infants and their mothers during pregnancy were reviewed. According to the prognosis, the infants were assigned into the survival group, the death group and the withdrawal group. According to GA, the infants were assigned into <26 w goup, 26~26 +6 w group, ≥27 w group. According to birth weight (BW), the infants were assigned in to ≤750 g group, 750~999 g group and ≥1 000 g group. SPSS 26.0 was used for data analysis. Results:A total of 265 EPIs were included, 122 (46.0%) in the survival group, 47 (17.7%) in the death group and 96 (36.2%) in the withdrawal group. GA and BW of the survival group were significantly higher than the death group and the withdrawal group ( P<0.05). The incidences of tracheal intubation (92.2%) and pulmonary hemorrhage (42.2%) in the death group were the highest among the three groups. The survival group had the highest application of prenatal glucocorticoids (80.3%) and pulmonary surfactants (99.2%) ( P<0.05). In the survival group, the top 3 common complications were bronchopulmonary dysplasia (BPD) (68.0%), pulmonary infections (65.6%) and neonatal sepsis (34.4%). The survival rate increased with GA and BW. Conclusions:The survival rate of EPIs is closely correlated with GA and BW. EPIs with pulmonary hemorrhage and tracheal intubation have poor prognosis. Prenatal glucocorticoids and pulmonary surfactant may improve clinical outcome. BPD and pulmonary infections are common complications of surviving EPIs.
