What we usually call “painless childbirth” is medically called “labor analgesia”. It is a method of reducing or even eliminating pain during childbirth. Painless delivery is already a routine form of childbirth abroad, which allows mothers to stop experiencing pain and reduces the fear of childbirth and postpartum fatigue. The more commonly used method is epidural analgesia. It is a low concentration of local anesthetics and analgesics injected into the epidural cavity by the pain unit or anesthesiologist in the mother’s lower back when the opening of the uterus reaches 3 cm. The analgesic effect is achieved by intermittent injection or automatic continuous administration with an infusion pump, and the analgesia can be maintained until the end of labor. The concentration of the anesthetic is about 1/5 of that of the anesthesia for cesarean section, which is low, with fast onset of analgesia, controllability and high safety. This method of painless delivery is the most widely used and most effective in major hospitals today. A skilled doctor can complete the procedure in about 5-10 minutes. The mother is awake during the whole procedure and can even get out of bed and walk around if she is able to do so, so she can feel the joy of her new life more comfortably and clearly. Most women are suitable for painless delivery, but women with heart disease, drug allergies, or history of back trauma should consult with their doctor to determine if painless delivery is possible. Does labor analgesia affect the baby? The biggest concern for mothers and their families about painless delivery is whether these anesthetic drugs will have an effect on the fetus and the mother’s health. Painless delivery is performed on the basis of the highest principle of safety for the mother and the fetus. The amount of medication absorbed through the placenta is minimal and has no adverse effects on the fetus, let alone on the brain health of the baby. On the contrary, painless delivery improves the safety of the mother and child during labor to varying degrees. Labor analgesia can shorten the labor process, reduce the rate of cesarean section and postpartum bleeding, improve placental blood flow, and reduce fetal hypoxia and neonatal asphyxia. Pain-free delivery is the hallmark of modern civilized obstetrics. Labor pain is an objective fact in human history and has a physiological and psychological basis. Humanity has always sought to find ways to make labor and delivery safe and painless. Labor analgesia has been studied for more than a century and it is the responsibility of the physician to provide this service. Childbirth is the process of reproduction, and a pain-free birth is the right of every woman and her baby. The mother has the right to a safe and happy delivery, and the fetus has the right to be protected and treated well during the process.
