Does painless surgery have any effect on the mother? Does painless surgery have any effect on the fetus?

In order to avoid pain during childbirth, doctors will give pregnant women painless injections. However, many expectant mothers are worried about the side effects of painless injections. So, should they be given painless injections? Does painless injections have any effect on the baby? Will painless injections cause harm to pregnant women?

What is a painless injection?

"Painless injection" is also known as "epidural anesthesia". It is a method of labor analgesia. It is not a problem of a needle, but a technology. It refers to puncturing the back of the parturient with an epidural puncture needle under local anesthesia, injecting the drug into the subarachnoid space through the spinal anesthesia needle, leaving an epidural catheter on the back, connected to an automatic electronic pump, and when the parturient feels pain, she presses a button once, and the drug is automatically injected into the epidural space to play an analgesic role. It can greatly reduce the pain of the parturient, but it is difficult to be completely painless because natural childbirth requires strong uterine contractions.

Does painless surgery have any impact on pregnant women?

The anesthesia effect is good, but there are certain risks for expectant mothers. Although epidural anesthesia has a good analgesic effect, there are also some risks for expectant mothers.

When giving an anesthetic injection, the anesthesiologist usually does the puncture based on feeling. A small number of them will mistakenly puncture the dura mater and arachnoid mater. At this time, cerebrospinal fluid will flow out, causing changes in intracranial pressure. At the same time, there is also a risk of infection.

If cerebrospinal fluid leakage occurs, the mother should lie flat without a pillow for 72 hours and receive adequate intravenous infusion every day. If the head is raised too early, it will cause headaches.

According to rough statistics in obstetrics, the incidence of this situation is about 1%.

Does painless surgery have any effect on the fetus?

The dosage of drugs used in painless delivery is extremely low, only 1/20 to 1/10 of that used in cesarean section. Therefore, the chance of entering the mother's blood and passing through the placenta is very small, and it will not cause any effect on the fetus. When the mother feels severe pain, a substance called catecholamine is released, which has adverse effects on both the mother and the fetus, and the blood and oxygen supply of the newborn may be affected. Therefore, painless delivery can also reduce the risk of fetal hypoxia. However, painless delivery requires certain risks for expectant mothers. General complications of painless delivery include hypotension and mild headaches, but serious life-threatening complications are relatively rare. Common adverse reactions are mainly manifested in the impact on the labor process and placental blood supply. Therefore, the entire delivery process requires obstetricians and gynecologists and anesthesiologists to jointly monitor the mother's condition.

Should I get the “painless delivery injection”?

Many mothers who have used epidural anesthesia to give birth know that when the cervix is ​​fully dilated, the analgesic effect wears off and the pain from contractions begins again.

Cai Jian, deputy chief physician of the obstetrics department of the First Affiliated Hospital of Sun Yat-sen University, said that this is because after the cervix is ​​fully dilated, the mother needs to push hard, and at this time, the amount of anesthetics needs to be reduced or 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 hard when she needs to.
