To assess the role of etamsylate in reducing the risk of haemorrhagic brain damage and its consequences.
Follow up of babies recruited into a randomised controlled trial.
A total of 334 infants born before 33 weeks gestation in France and Greece were randomly allocated within the first four hours of birth either to receive etamsylate or to act as controls. The principal outcomes in the trial were death or impairment and/or disability at the age of 2 years.
Fifty nine children were lost to follow up. A total of 115 (34%) either died or had some impairment or disability, and 88 (26%) either died or had severe impairment or disability at 2 years of age. These outcomes did not differ significantly between the two randomised groups: relative risks and 95% confidence intervals 1.14 (0.78 to 1.4) and 1.17 (0.82 to 1.68) respectively. The findings were similar for all the prespecified subgroup analyses stratified by key prognostic factors at trial entry: country of birth, gestational age < or >or= 29 weeks, inborn or outborn, age < or >or= 1 hour, and with or without cerebral scan abnormality.
These findings do not support the use of etamsylate. Other strategies need to be evaluated for the prevention of mortality and morbidity in these vulnerable infants.
评估酚磺乙胺在降低出血性脑损伤风险及其后果方面的作用。
对纳入一项随机对照试验的婴儿进行随访。
在法国和希腊,共有334名孕33周前出生的婴儿在出生后的头4小时内被随机分配,分别接受酚磺乙胺治疗或作为对照。该试验的主要结局是2岁时的死亡、损伤和/或残疾。
59名儿童失访。共有115名(34%)儿童在2岁时死亡或有某种程度的损伤或残疾,88名(26%)儿童死亡或有严重损伤或残疾。这两个随机分组之间的这些结局没有显著差异:相对风险及95%置信区间分别为1.14(0.78至1.4)和1.17(0.82至1.68)。对于根据试验入组时的关键预后因素进行分层的所有预先设定的亚组分析,结果相似:出生国家、胎龄<或≥29周、足月儿或早产儿、出生时年龄<或≥1小时,以及有无脑部扫描异常。
这些研究结果不支持使用酚磺乙胺。需要评估其他策略以预防这些脆弱婴儿的死亡和发病情况。
