【摘要】：目的比较早、晚期早产儿呼吸窘迫综合征(RDS)的特点,探讨晚期早产儿RDS的高危因素和临床特点。方法选择2014年1月至2015年1月在该院住院240例早产儿RDS,根据胎龄分为两组,34周为早期早产儿组(143例),34~36~(+6)为晚期早产儿组(97例)。回顾性分析早产儿RDS的基本情况、围生期高危因素、临床特点、治疗及预后。结果晚期早产儿组分娩方式以剖宫产为主,剖宫产率达83.51%,明显高于早期早产儿组(P0.05)。晚期早产儿组因先兆子宫破裂行剖宫产致早产的发生率较高(27.84%);肺表面活性剂(PS)及无创辅助通气治疗效果较早期早产儿差,且机械通气率高,通气时间长;肺动脉高压发生率、宫内感染的发生率亦高于早期早产儿组(P0.05)。结论晚期早产儿RDS以产程未发动的剖宫产为主,宫内感染可能为其高危因素,PS应用有效,但较早期早产儿效果差;晚期早产儿机械通气率较高,但预后良好。
[Abstract]:Objective to compare the characteristics of respiratory distress syndrome (RDS) in premature and advanced premature infants. To investigate the high risk factors and clinical characteristics of advanced premature infants (RDS). Methods from January 2014 to January 2015, 240 premature infants in our hospital were selected and divided into two groups according to gestational age. There were 143 cases of early preterm infants in 34 weeks and 97 cases of advanced premature infants (6). The basic condition of RDS, perinatal high risk factors and clinical characteristics of premature infants were analyzed retrospectively. Results cesarean section was the main mode of delivery in advanced premature infants, and the cesarean section rate was 83.51%. The incidence of premature delivery due to threatened rupture of uterus was higher than that of early premature infants (27.84%). Pulmonary surfactant (PSV) and non-invasive auxiliary ventilation were less effective than early premature infants, and the mechanical ventilation rate was higher and the ventilation time was longer. The incidence of pulmonary hypertension and intrauterine infection was also higher than that of early premature infants (P 0.05). Conclusion RDS of late premature infants is mainly cesarean section which is not initiated during labor, and intrauterine infection may be the high risk factor. PS was effective, but the effect of PS was worse than that of early premature infants. The mechanical ventilation rate of late premature infants is high, but the prognosis is good.

【正文快照】： 晚期早产儿指胎龄为34~36+6周出生的新生儿,曾被称为“近足月儿”,2005年由美国国家儿童健康与人类发展研讨会建议命名为“晚期早产儿”。有研究指出早产儿出生率的上升主要是由于晚期早产儿数量的增加,晚期早产儿占全部早产儿的比例高达60%~70%[1-3]。长期以来,由于晚期早产
