Respiratory distress syndrome (RDS) is a common cause of respiratory distress in premature infants. This study was designed to evaluate two different RDS treatment protocols by comparing the outcomes.
This study was a double center cross sectional study performed from June to December 2012. During that period, 386 neonates with RDS were hospitalized and treated according to two different therapeutic protocols so-called Acute Care of at-Risk Newborns (ACoRN) respiratory sequence protocol (group I) and Early Nasal Continuous Positive Airway Pressure (E-NCPAP) protocol (group II). The variables and main outcomes of this study were gestational age, birth weight, bronchopulmonary dysplasia (BPD), pulmonary hemorrhage (PH), intraventricular hemorrhage (IVH), air leak and mortality rate (MR). Findings : Out of 386 infants, 202 infants were in group I (male 60.4%, female 39.6%, mean gestational age 31(6/7) weeks, mean birth weight=1688 grams) and group II included 184 infants (male 61.4%, female 38.6%, mean gestational age 32 weeks, mean birth weight 1787 grams), P= 0.07. The ratios of BPD of group I to group II and PH of group I to group two were not significant (P=0.63 and P=0.84, respectively). Air leak ratio in group I was higher than in group II (P=0.001). Although IVH ratio in group II was higher than in group I (P=0.01), grade III and IV IVH was higher in group I (30% vs. 4.6%). In case of MR, it was higher in group I than in group II (P=0.001).
According to the findings the incidence of air leak, grade III and IV IVH and MR was less common in E-NCPAP protocol, so it may show the effectiveness of this protocol. The authors suggest that more researches are needed for more accurate results.
呼吸窘迫综合征(RDS)是早产儿呼吸窘迫的常见原因。本研究旨在通过比较两种不同的RDS治疗方案的结果来评估它们。
本研究是一项双中心横断面研究,于2012年6月至12月进行。在此期间,386例RDS新生儿住院并根据两种不同的治疗方案进行治疗,即高危新生儿急性护理(ACoRN)呼吸序列方案(第一组)和早期鼻持续气道正压通气(E-NCPAP)方案(第二组)。本研究的变量和主要结局为胎龄、出生体重、支气管肺发育不良(BPD)、肺出血(PH)、脑室内出血(IVH)、气漏和死亡率(MR)。结果:386例婴儿中,202例在第一组(男性60.4%,女性39.6%,平均胎龄31(6/7)周,平均出生体重1688克),第二组包括184例婴儿(男性61.4%,女性38.6%,平均胎龄32周,平均出生体重1787克),P = 0.07。第一组与第二组的BPD比率以及第一组与第二组的PH比率均无统计学意义(分别为P = 0.63和P = 0.84)。第一组的气漏比率高于第二组(P = 0.001)。虽然第二组的IVH比率高于第一组(P = 0.01),但第一组的III级和IV级IVH更高(30%对4.6%)。在死亡率方面,第一组高于第二组(P = 0.001)。
根据研究结果,E-NCPAP方案中气漏、III级和IV级IVH以及死亡率的发生率较低,因此可能表明该方案的有效性。作者建议需要进行更多研究以获得更准确的结果。
