It mainly includes taking good care of the mother, carefully observing the labor process, and guiding her to correctly cooperate with the progress of labor and delivery (delivery). If the labor progresses slowly after it starts, and examination reveals abnormalities in the birth canal or fetus, such as a tight perineum of the mother, heart disease that makes it difficult to exert force, abnormal fetal position, etc., surgery to prepare the birth canal (such as episiotomy), surgery to solve delivery (such as vacuum extraction, forceps, gluteal traction), and surgery to change the fetal pole (such as internal version, etc.) can be used.
