Painless labor means painless delivery. Most pregnant women who choose painless labor can have a normal delivery, not necessarily a cesarean section. Painless labor is also known as labor analgesia, which is a method of reducing pain and improving comfort during labor through analgesic drugs. Usually, after the uterine opening is 3-4cm wide, you can ask for painless labor and delivery, and the commonly used methods are epidural anesthesia and so on. The choice of painless labor does not mean that pregnant women must choose cesarean section. Most women who have a normal delivery in the middle and late stages of the opening of the uterus are unable to tolerate the pain of contractions and the opening of the bones, so they choose to have labor pains in order to alleviate the pain, save physical strength, and contribute to a smooth delivery. However, if the fetus suffers from intrauterine oxygen deprivation or other abnormalities during a normal delivery, it may be necessary to switch to cesarean section, which can be supported by anesthesia provided by painless labor and an increased dosage of anesthesia medication, among other things.
