My daughter is five years and three months old. A cold and cough put her in a coma for several hours every day. Do you need a bone marrow puncture? Will it affect the child's future?

Don't do it, unless the doctor suspects that her hematopoietic function is abnormal (such as anemia). Generally, bilateral ilium is selected for bone marrow puncture, which is very safe and has no influence. Of course, nothing is so absolute. An injection may damage the nerves, right? For the sake of children's health, I suggest going to the hospital.
