Acute hemorrhage in preterm infants leads immediately to a life-threatening event because of the small circulating blood volume. The beneficial use of recombinant activated Factor VII (rFVIIa; NovoSeven, NovoNordisk, Gentofte, Denmark) as hemostatic treatment in neonates with hemorrhagic shock has been described. Necrotizing enterocolitis is a challenge in neonatology as the disease represents one of the leading causes of mortality in preterm infants. We report on the use of rFVIIa in very low birth weight (<1500 g), preterms with intestinal hemorrhage, and disseminated intravascular coagulation (DIC).
Retrospective analysis of 5 cases.
Five preterm infants <or=28 weeks gestational age with DIC and hemorrhagic shock due to severe diffuse gastrointestinal bleeding.
Intravenous bolus administration of 100 to 180-microg/kg rFVIIa (total of 9 doses) as rescue procedure after other interventions (substitution of platelets, fresh frozen plasma, red packed cells, surgery) failed to achieve hemostasis.
Two patients with severe acidosis, hypothermia, and thrombopenia died in hemorrhagic shock, treatment with rFVIIa was unsuccessful. In 3 patients, rFVIIa was effective and gastrointestinal bleeding could be stopped. No acute adverse event, increasing bowel necrosis, increasing platelet consumption, or thromboembolic complications were observed.
In this small group of preterms with DIC, intestinal hemorrhage, and persistent hemorrhagic shock, rFVIIa was effective as a rescue therapy but failed in patients with severe acidosis, hypothermia, and thrombopenia.
由于循环血容量小,早产儿急性出血会立即导致危及生命的事件。已有报道称重组活化凝血因子VII(rFVIIa;诺其,丹麦诺和诺德公司,根措夫特)在新生儿出血性休克的止血治疗中具有有益作用。坏死性小肠结肠炎是新生儿学中的一项挑战,因为该疾病是早产儿死亡的主要原因之一。我们报告了rFVIIa在极低出生体重(<1500g)、伴有肠道出血和弥散性血管内凝血(DIC)的早产儿中的应用情况。
对5例病例进行回顾性分析。
5例胎龄≤28周的早产儿,因严重弥漫性胃肠道出血导致DIC和出血性休克。
在其他干预措施(输注血小板、新鲜冰冻血浆、红细胞悬液、手术)未能止血后,作为抢救措施静脉推注100至180μg/kg的rFVIIa(共9剂)。
2例伴有严重酸中毒、体温过低和血小板减少的患者死于出血性休克,rFVIIa治疗无效。3例患者中,rFVIIa有效,胃肠道出血得以停止。未观察到急性不良事件、肠坏死加重、血小板消耗增加或血栓栓塞并发症。
在这一小群患有DIC、肠道出血和持续性出血性休克的早产儿中,rFVIIa作为抢救治疗是有效的,但在伴有严重酸中毒、体温过低和血小板减少的患者中无效。
