1. The commonly referred to as "painless delivery" is medically called "delivery analgesia", which uses various methods to reduce or even disappear the pain during childbirth. Analgesia during childbirth can help mothers-to-be no longer experience pain, reduce the fear of childbirth and postpartum fatigue, and allow them to rest during the longest first stage of labor. When the uterine orifice is fully opened, they will be saved by the accumulation of physical strength. Have enough strength to complete labor
2. Method: After successfully puncturing the lumbar intervertebral space, the anesthesiologist injects a small amount of local anesthetics or opioids into the subarachnoid space, and inserts a thin catheter into the epidural space. One end of the catheter is connected to an electronic analgesic pump. The mother self-controls the administration according to the degree of pain (the anesthesiologist has set an hourly limit, and there is no need to worry about overdose), and the analgesic pump can be used continuously until the end of the delivery.
3. Advantages: （1）Safety: intraspinal block is used for painless delivery. The doctor places a catheter in the lumbar epidural space of the parturient. The concentration of anesthetic in the analgesic pump is equivalent to 1/5～1/ of that of the cesarean section. 10, that is, a light anesthetic, which is very safe.（2）Convenience: Because the concentration of anesthetics is very low, it hardly affects the movement function of the parturient, so the parturient can get out of bed with the permission of the doctor; in addition, the parturient can self-control the administration according to the degree of pain, which is truly individualized , So very convenient. 3. Long-lasting drug effect: about 10 minutes after the administration, the parturient will not feel the intense pain of uterine contractions, and the pain that can be felt is like a slight abdominal pain during menstruation. Once the medicine is given, the effect lasts for about an hour and a half or even longer. After the pain is felt, the parturient will continue to use an analgesic pump to control the analgesia. This is repeated until the end of the delivery. 4. Suitable for a wide range of people: most women are suitable for painless childbirth, but if they are combined with coagulation dysfunction, drug allergies, waist trauma and other diseases, the mother should consult a doctor, and the doctor will decide whether it is possible to have a painless childbirth. 5. No need to enter the operating room: the entire process of painless delivery is done by the anesthesiologist and obstetrician and gynecologist. Normal painless delivery can be carried out in the delivery room without entering the operating room.
4. Contraindications: Women with contraindications to vaginal delivery, intraspinal anesthesia, and abnormal blood coagulation cannot use this method.
5. Precautions: 1. After adopting painless delivery, labor is required to give birth: the analgesic used now is a kind of nerve blocker with "sensation and movement separation", which selectively blocks the transmission of pain in the parturient, and Motor nerves are not affected. During childbirth, the parturient is fully mobile, and the contractions of the abdominal muscles and uterus remain normal. On the contrary, after the pain of the parturient is relieved, the spirit is completely relaxed, and the whole body is no longer twisted, which is beneficial for the parturient to exert force under the guidance of the doctor, and the opening of the uterine mouth is easier, thus accelerating the progress of the labor process. 2. There will be slight discomfort during spinal puncture and catheterization: the puncture and catheterization are performed under local anesthesia, and the parturient feels only mild discomfort, which is not comparable to the birth pain during uterine contraction. 3. In the painless delivery, the delivery method may be changed to cesarean section: whether natural delivery is changed to cesarean section is not necessarily related to whether the painless delivery is performed. It depends on whether the fetal head and pelvis are commensurate, whether there is abnormal fetal position, Obstetrical factors such as umbilical cord around the neck and fetal distress. Some factors can only be gradually revealed during delivery. If cesarean section is required during labor analgesia, the parturient can enter the operating room for surgery in time. If delivery is analgesic The effect is definite, and the procedure of re-spinal canal puncture can be avoided by administering medicine at the place where the tube is inserted, and the preparation time before the operation is saved.
