Abstract:
Objective To analysis the clinical outcome at discharge and its risk factors of extremely preterm infants.Method To retrospectively analysis the clinical outcome at discharge and it's risk factors of extremely preterm infants (less than 28 weeks gestation) admitted from September 2008 to August 2014 in our Hospital.Result A total of 179 cases were enrolled.Survival rate was 59.2％ (106/179).Unfavorable outcome rate was 74.3％ (133/179),among them 73 cases died.The top five causes of death were severe bronchopulmonary dysplasia (BPD) (28 cases),Ⅲ ～ Ⅳ o intraventricular hemorrhage (IVH) (19 cases),sepsis (16 cases) and necrotizing enterocolitis (NEC) (6 cases).Among the 60 survivals with unfavorable outcomes,35 cases had either severe neurologic or ophthalmological sequela,and 25 cases had severe pulmonary sequela.Univariate analysis showed that,comparing with improved group,unfavorable outcome group had higher rates of not receiving prenatal steroids,placental abruption,male,small for gestation age,resuscitation with chest compression,admission age older than 72 hour,severe respiratory distress syndrome (RDS),without pulmonary surfactant (PS) usage,mechanical ventilation beyond 2 weeks and sepsis (P ＜ 0.05).Logistic regression analysis showed that those without prenatal steroids (OR =9.402,P =0.002),small for gestational age (OR =8.271,P =0.018),resuscitation with chest compression (OR =6.325,P =0.023),admission age older than 72 hour (OR =4.174,P =0.028) were independent risk factors for unfavorable outcome of extremely premature at discharge.Conclusion Extremely preterm infants have a higher rate of unfavorable outcome at discharge.Avoid small for gestational age,transfer properly and in time both in utero and after birth,and conduct prenatal steroids could improve their clinical outcome at discharge.
