The main ways to avoid tearing in normal labor are avoiding rapid labor, protecting the perineum, and restrictive episiotomy, etc. However, most pregnant women will have tearing, which is difficult to avoid completely. 1. Avoiding rapid labor: During normal labor, one should follow the doctor’s instruction to push correctly and give the perineum sufficient time to dilate, so as to avoid tearing due to the rapid delivery of the fetal head and shoulders. 2. Protect the perineum: when the tension of the posterior perineal union is tight, attention should be paid to protect the perineum, so that the fetal head can pass through the vaginal opening slowly with the smallest diameter during the contraction interval to prevent tearing. 3. Restrictive episiotomy: For those who have a tight perineum or a large fetus, and it is estimated that perineal tear is unavoidable during labor, an episiotomy can be used to reduce the risk of serious perineal laceration. It is difficult to avoid tearing completely, so it is recommended to relax your mind. Reasonable nutrition during pregnancy, regular checkups and avoiding oversized fetus can help reduce the risk of tearing during labor.
