A 6-week-old breast-fed infant presented with vomiting, jaundice, and irritability. Haemorrhage occurred after lumbar puncture, and a coagulation abnormality which responded to vitamin K was found. It would seem prudent to estimate the prothrombin time before invasive procedures in breast-fed infants of this age, or to give vitamin K to such infants when doubt exists about previous vitamin K administration.
一名6周大的母乳喂养婴儿出现呕吐、黄疸和易激惹症状。腰椎穿刺后发生出血，并发现一种对维生素K有反应的凝血异常。对于这个年龄段的母乳喂养婴儿，在进行侵入性操作前估计凝血酶原时间，或者在对先前是否给予维生素K存在疑问时给此类婴儿补充维生素K，似乎是谨慎的做法。
