The indications for forceps are as follows: 1, the opening of the uterus is combined with prolongation of the second stage of labor, for example, persistent occipital transverse position requires forceps; 2, if pregnancy combined with heart disease or pregnancy combined with complications, the second stage of labor needs to be shortened; 3, there is intrauterine distress, intrauterine hypoxia, and the pregnancy needs to be terminated urgently. For example, if the fetal heart rate is only 50-60 times after the opening of the uterus, it is necessary to use forceps to pull out the fetus, which can reduce the adverse neonatal outcome and neonatal asphyxia; 4, it is difficult to deliver the fetal head in breech position, and the fetal head is delivered with forceps; forceps is the most common and frequently used procedure in obstetrics to solve difficult labor, and is used to assist the second stage of labor, with forceps on both sides of the fetal head, and after the forceps are closed with contractions The forceps are placed on both sides of the fetal head, and the forceps are used to pull and tug the fetal head after the contractions, so that the fetal head can be delivered smoothly, which is a relatively safe, mature and effective way to assist delivery. The use of forceps is a relatively safe, mature and effective way to assist the delivery of the fetal head when the uterus is fully opened and the fetal position is low, but the fetal head cannot be delivered smoothly or the fetus needs to be delivered smoothly within a short period of time.
