Obstetric tumor is also known as pioneer head or scalp edema, its elimination time varies according to the newborn’s physical state, the individual size of the obstetric tumor, the presence or absence of hematoma, etc. Most of them can be eliminated in 2-4 days, and the longest elimination time is 1-2 months. Hematoma is an edema or hematoma of the scalp caused by uterine contractions and pressure from the birth canal or by external forces such as forceps when the scalp is pulled during the delivery of a newborn. When scalp edema occurs, it does not require special treatment and usually resolves on its own within 2-4 days after birth, up to a maximum of 7 days. If there is hematoma or edema of the scalp is large, it first becomes a hard lump and then slowly absorbs, taking 1-2 months to eliminate. During normal care, care needs to be taken not to shake the newborn’s head, so as not to affect the elimination of the birth tumor. Although the elimination of the tumor does not require special treatment, if it remains for too long, it is necessary to go to the pediatric department of the hospital.
