When is the painless delivery injection given? Where is the painless delivery injection given?

The pain index of childbirth is indescribable. With the advancement of science and technology, painless childbirth technology has also been developed. Today, the editor of No. 5.com will introduce to you when the painless childbirth injection is given? Where is the painless childbirth injection given?

When should the painless delivery injection be given?

For safety reasons, most hospitals in China currently perform spinal blockade when the cervix is ​​dilated to 2-3 cm. Painless childbirth does not involve the use of anesthetics from the very beginning, but rather the injection of drugs when the cervix is ​​dilated to 3 fingers. The drug effect generally lasts for an hour and a half, or even longer, and the drug is injected again after the pain is felt, and this is repeated until the end of childbirth. It can block the sensory nerves of the mother in labor, but does not affect her uterine contraction and motor nerves. Moreover, the mother in labor is clear-headed and can actively cooperate and participate in the entire childbirth process.

Will the pain go away after taking the pain-relieving injection?

The painless delivery injection cannot completely eliminate the pain, but it can reduce the pain by about 50%. The painless delivery injection is generally an epidural block. It is to reduce the pain by applying anesthetics locally to prevent the sensory nerves in the abdomen from transmitting pain signals to the brain. "Painless delivery" does not mean that the entire delivery process is painless. When the cervix is ​​fully dilated, the analgesic effect weakens, and the pain during contractions begins again. This is because after the cervix is ​​fully dilated, the mother needs to push, and at this time, the amount of anesthetics needs to be reduced or the analgesia needs to be stopped. If anesthesia is still used at this time, the mother's anal reflex will be very weak, and she will not be able to push well when she should.

Does painless childbirth have any effect on the baby?

It should be said that there is no effect. Although this medicine can be absorbed through the placental barrier, its concentration is very low, only 1/10 of the ordinary cesarean section anesthesia solution, and it is injected outside the dura mater. The medicine must first penetrate the dura mater, then be absorbed and distributed in the blood throughout the body, and then pass through the placental barrier. The components that can be absorbed by the child are very few. And the fetus has the ability to metabolize this medicine.
