If a newborn is born in a normal birth, due to the compression of the birth canal, sometimes there will be a scalp hematoma, a small one of two or three centimeters, a large one may be more than ten centimeters. Most obstetricians will downplay this and say it’s okay, it will be absorbed naturally. This is basically true, but there is a 1 percent chance that it is wrong! Why? It turns out that there are two kinds of scalp hematoma, one is subcapsular hematoma, which is the 99% of the cases; and the other is subperiosteal hematoma, which only accounts for 1%, but can be troublesome if not treated in time, because not only will it not absorb, it will ossify! So the question arises, how to distinguish these two kinds of hematomas? In the early stage of hematoma, it is really hard to distinguish! So what to do? 1. Avoid compressing the hematoma, nor rubbing it, nor applying ointments that activate blood stasis and reduce hematoma. 2. Do not puncture and aspirate early, because the newborn’s skin is delicate and easily infected. And if it is a subcapsular hematoma, it will be absorbed by itself, so why let the baby suffer? So what should be done for proper management? Observe for three weeks, and if the hematoma is still there, see a neurosurgeon at Children’s Hospital, and the doctor will give you professional treatment. Because after three weeks, the subperiosteal hematoma may begin to slowly ossify, and if it is any later, it will not be able to be pumped out.
