Painless childbirth is actually a folk term for what is medically known as analgesic childbirth, which is mainly used to reduce pain during labor through medication. Analgesic childbirth has a history of more than 100 years in foreign countries, and the use in developed countries is close to 100%. In recent years, it has been widely popularized and promoted in large and medium-sized cities, but so far, only a part of women have enjoyed this medical technology achievement, mainly due to the lack of publicity in hospitals and the limited number of women who know about this service; in addition, some women worry about the effect of drugs on the fetus, which also limits the development of this service. According to the survey, labor pains during childbirth may be the cruelest pains that many women have experienced in their lives, and some of them would describe the pains during childbirth as “painful” and “unbearable”, so eliminating pains is undoubtedly a boon for the majority of women. The elimination of pain is a boon for women. There are two more established methods of analgesia for labor and delivery: intradural anesthesia and laughing gas inhalation anesthesia, both of which provide excellent pain relief. In addition, if other problems arise during labor that require a cesarean section, in most cases the method can be continued without further anesthesia; the laughing gas inhalation method is simple and easy to operate, and the effect is reliable, i.e., every time a woman feels pain, she inhales the configured laughing gas inhalation anesthesia. The method is simple, easy to use and reliable, that is, every time the mother feels pain, she can inhale the gas, but she needs to do it by herself, at the same time, if the mother is not sure, the effect may appear a little later, which has the disadvantage that the analgesia is a little later, so it is less used at present. During the process of analgesic delivery, there is a special guide accompanying the whole process, and both the adult and the fetus are monitored, so any problems can be found in time and dealt with accordingly, so the safety of both the adult and the child is guaranteed, and the mother and her family can feel at ease and enjoy the fun of labor analgesia, waiting for the baby to come in a relaxing atmosphere.
