To compare the efficacy of two natural surfactants for pulmonary hemorrhage in very low-birth-weight (VLBW) infants.
A prospective randomized controlled trial was conducted on 42 infants who were divided into two groups, poractant alfa (n = 21) and beractant (n = 21).
In both the groups, the mean standard deviation (SD) birth-weight and gestational age were similar (p = 0.33 and 0.89, respectively). Although, the mean oxygenation index (OI) increased after pulmonary hemorrhage compared with baseline value and decreased after surfactant in both groups, variations in OI were more prominent in poractant alfa group (before hemorrhage: 11.9, after hemorrhage: 22.7, 1 hour of surfactant: 14.6, 8th hour of surfactant: 7.8, 24th hour of surfactant: 8.5, p = 0.007 vs. before pulmonary hemorrhage:11.1, after pulmonary hemorrhage: 17.9, 1 hour of surfactant: 12.8, 8th hour of surfactant: 12.8, 24th hour of surfactant: 9.7, p = 0.02). There was no significant difference between the groups for OI values at all time points (p > 0.05). The rates of bronchopulmonary dysplasia (BPD) and mortality related to pulmonary hemorrhage were similar in both the groups.
Both natural surfactants improved oxygenation when administered for pulmonary hemorrhage in VLBW infants. The type of surfactant seems to have no effect on BPD and mortality rates in these patients.
比较两种天然表面活性剂用于极低出生体重(VLBW)婴儿肺出血的疗效。
对42例婴儿进行前瞻性随机对照试验,将其分为两组,即猪肺磷脂(n = 21)组和牛肺表面活性剂(n = 21)组。
两组的平均标准差(SD)出生体重和胎龄相似(分别为p = 0.33和0.89)。虽然两组肺出血后平均氧合指数(OI)较基线值升高,使用表面活性剂后降低,但猪肺磷脂组OI的变化更显著(肺出血前:11.9,肺出血后:22.7,使用表面活性剂1小时:14.6,使用表面活性剂8小时:7.8,使用表面活性剂24小时:8.5,p = 0.007;相比之下,肺出血前:11.1,肺出血后:17.9,使用表面活性剂1小时:12.8,使用表面活性剂8小时:12.8,使用表面活性剂24小时:9.7,p = 0.02)。两组在所有时间点的OI值均无显著差异(p>0.05)。两组支气管肺发育不良(BPD)发生率及与肺出血相关的死亡率相似。
两种天然表面活性剂用于VLBW婴儿肺出血时均能改善氧合。表面活性剂类型似乎对这些患者的BPD发生率和死亡率无影响。
