晚期早产儿的临床回顾分析

Objective To analyze if late preterm infants have more postnatal health issues than full term infants.Methods Two thousands four hundreds and ten neonatal records were reviewed from August 31st 2007 to September 1st 2008.There were totally 508 late preterm and 1 514 full term infants were admitted during that time.The incidence of hypothermia,jaundice,hypoglycemia,transient tachypnea of newborn,feeding difficulties,respiratory distress and intracranial hemorrhage was collected.Clinical prognosis was analyzed.Results The incidence of hypothermia was significantly higher in late preterm infants group as compared to full term infants group(13.4% vs 0),same as hypoglycemia(19.9% vs 3.0%,P ＜0.01),respiratory distress(38.6% vs 10.8%,P ＜ 0.01),jaundice(55.0% vs 33.0%,P ＜ 0.01),feeding difficulties (52.4% vs 14.2%,P ＜0.01),transient tachypnea of newborn(31.0% vs 13.1%,P ＜0.01)and intracranial hemorrhage(5.1% vs 2.3%,P ＜0.01).The proportion of ventilation,the usage of surfactant and nasal continuous positive airway pressure were higher in late preterm infants group and the withdrawal rate was also higher as compared to full term infants group.Conclusion Late preterm infants have more complications versus full term infants and it has potential unrecognized risk among neonatal population.
