Painless childbirth originated in foreign countries and is widely used in the United States, the United Kingdom, and other countries. Its purpose is to achieve the alleviation of childbirth pain through various methods. Currently, there are mainly two categories: non-drug analgesia and drug analgesia. Non-drug analgesia includes breathing methods, comfort methods, water birth, massage, etc., and these types of analgesia have poor effects. Drugs include inhalation of laughing gas, intramuscular injection of analgesics, intraspinal analgesia for childbirth, etc. The last one is the true meaning of "painless childbirth," with the most obvious analgesic effect. Although painless childbirth has analgesic effects, it cannot completely eliminate pain. It can help the mother to alleviate pain during the first stage of childbirth, which is the most painful and longest period of cervical dilation, and will not waste energy due to shouting. When the cervix is fully dilated, the mother has regained strength through rest, and can smoothly complete the subsequent childbirth. What are the benefits of painless childbirth? 1. Effective pain relief. Before administration, the mother is in severe pain, but after administration for less than ten minutes, the severe pain will subside, allowing the pain to be within tolerable limits. Mothers who have experienced it around them said that after using painless childbirth, they immediately felt much more relaxed and had no pressure lying in bed and taking selfies to post on social media. 2. Safety. Many people are afraid that painless childbirth will affect the intelligence of the fetus, but in fact, as long as a qualified anesthesiologist is used and the medication dosage is appropriate, it is very safe. 3. Wide applicability. Except for those with anesthesia contraindications, coagulation dysfunction, and contraindications for vaginal delivery, most mothers are suitable for painless childbirth. Mothers with a history of drug allergies, complications during pregnancy, etc., should inform the doctor in advance so that the doctor can determine whether painless childbirth is possible.
