امید به حیات و بروز عوارض در نوزادان با وزن تولد کمتر از 1000 گرم

Background: Much has changed in neonatal care for extremely low birth weight (ELBW birth weight <1000g) infants over the recent years in Iran, resulting in an increase in their survival rate. We determined neonatal survival and short-term morbidity rates among ELBW infants, and the correlation of these factors with mortality risk. Methods: All single live-born ELBW babies delivered at Vali-e-Asr Hospital over a four-year period were identified. Data that were prospectively collected included: maternal age, prenatal and perinatal complications, antenatal steroid use, birth weight, gestational age, route of delivery, sex, need for resuscitation, APGAR score, need for mechanical ventilation, and complications including respiratory distress syndrome (RDS), sepsis, jaundice, intraventricular hemorrhage (IVH), necrotizing entrocolitis (NEC) metabolic and hematologic and cardiac disorders. Information was statistically analyzed and a probability value of <0.05 was considered significant. Results: A total of 93 neonates were included in the study. The survival rate in the delivery room was 36.6%. The lowest birth weight was 400g, with a mean birth weight of 850.43(±136.48)g, and the lowest gestational age was 22 weeks. The mean gestational period was 28.31(±2.77) weeks. The most frequent complication after birth was RDS(69.89%) and the least frequent was NEC (6.4%). Short and normal gestation was observed in 44.08% and 48.4% of the neonates, respectively. There was a significant relationship between neonatal mortality and the need for resuscitation after birth, RDS and need for a respirator (p<0.05). Furthermore, there was significant increase in mortality among neonates with gestational age <30 weeks, birth weight under 750g and lack of steroids before birth (p<0.05).Conclusions: To enhance perinatal and neonatal care and decrease the rate of preterm labor, improved standard resuscitation and increased administration of antenatal steroids and respirators are required.
