88例小婴儿中风中,78.4%为母乳喂养儿,其次为新生儿黄疸、肝动能异常、感染及反复使用抗生素等有关,但与发病季节无关。本组中有15例曾有过一过性黑粪史,这可能是本症的早期表现。经补充VitK 后皆能止血,但痊愈者只占43%,13例死亡,37例有神经系统后遗症。认为母乳喂养儿及新生儿期以及反复感染儿应预防性补充VitK。 Among the 88 infants with stroke, 78.4% were breastfeeding children, followed by neonatal jaundice, abnormal liver motility, infection and repeated use of antibiotics, but not related to the season of onset. In this group of 15 patients had had a transient history of black manure, which may be the early manifestation of this disease. After VitK hemostasis can be completed, but only 43% of those who healed, 13 died, 37 patients had neurological sequelae. That breastfeeding children and neonatal and recurrent infections should be prophylactic VitK.
