Why can I have a painless injection with a 3-finger opening?

Today's technological progress is becoming more and more advanced, and pregnant women have a large number of delivery methods to choose from, but the vast majority of pregnant women still follow the traditional delivery method - choosing natural birth. Choosing natural childbirth is not only good for the pregnant woman's physical recovery, but also beneficial for the birth of the baby.

However, if a pregnant woman chooses to give birth naturally, she needs to experience the pain of giving birth naturally. Therefore, in order to reduce the pain of pregnant women, many hospitals have introduced labor analgesia, which can make pregnant women more relaxed during labor. But why do pregnant women need to dilate three fingers before they can get an epidural?

In fact, pregnant women need to go through three processes during childbirth, and the implementation of labor analgesia needs to be based on the specific situation of the pregnant woman and the professional skills of the doctor. Not every pregnant woman is suitable for labor analgesia. Pregnant women often have to dilate three fingers before they can get an epidural. This is because at this time the pregnant woman's uterus contracts regularly and the pain is not severe, and the pain-free period lasts for one or two hours. If labor analgesia is performed after the cervix is ​​dilated to four fingers, the anesthetic will last longer in the spinal canal, which will affect the normal force of the pregnant woman during labor and be detrimental to delivery.

Until the pregnant woman's cervix is ​​dilated to 3 fingers, the uterine contractions are regular, so this is the most appropriate time to carry out labor analgesia and anesthesia. Pregnant women will not feel very painful at this time, mainly because the anesthetic will end when the baby is about to be born, so as to avoid not having the strength to give birth to the baby at that time. If an anesthetic is injected more than four fingers, or the anesthetic effect has not worn off when the baby is ten fingers open, then there will be no chance of giving birth.

Therefore, for the safety of pregnant women and their babies, the doctor will understand the time when the pregnant woman's cervix is ​​dilated and then decide whether to perform an epidural. In addition, labor analgesia is a method of injecting anesthetics into the body's spinal canal, so the dosage of the drug must be accurately calculated. If you are not careful, it will affect the safety of the baby. Therefore, pregnant women should first choose a reliable and attentive hospital to give birth.

In addition, pregnant women should understand that labor analgesia will cause side effects. Most pregnant women will experience vomiting, headaches, drug allergies, etc. after labor analgesia. Pregnant women should be fully prepared, respond to emergencies rationally, tell their doctors immediately, and maintain a stable mood.
