The pain of induced labor is similar to that of normal delivery, and the degree of pain mainly depends on the pain sensitivity, the level of cervical dilation, the level of contractions, the size of the pregnancy week, etc., which cannot be generalized. 1. pain sensitivity: compared with pregnant women with high pain tolerance, pregnant women with low pain tolerance feel more pain; 2. level of cervical dilation: when inducing labor, the doctor needs to dilate the cervix, and the greater the degree of dilatation, the greater the pain will be; 3. level of contractions: if contractions are frequent and longer, most pregnant women will feel more pain; 4. The greater the degree of dilatation, the greater the pain will be; 3, the level of contractions: if contractions are frequent and longer, pregnant women will feel more pain; 4, the size of the pregnancy week: in general, the fetus induced before 28 weeks of pregnancy is relatively small, the majority of pregnant women in the process of induction of labor pain is not particularly strong and can be tolerated; after 28 weeks of pregnancy, the fetus is generally larger, in the process of delivery, the pressure on the pelvic floor is more obvious, the more intense the pain. At this stage, induction of labor can be carried out as a painless surgical operation, so women may not feel pain during induction of labor. Painless surgery includes pre-surgical anesthesia and post-surgical pain relief. Pre-surgical anesthesia can be selected according to the condition of the disease, local or general anesthesia, which can prevent or reduce the pain from surgical treatment; post-surgical pain relief is generally selected from pain pumps, which can have the effect of post-surgical pain relief.
