The harm of painless childbirth injections and painless childbirth experience

Everyone is familiar with painless childbirth. It is a method of delivery that has become popular from abroad. Painless childbirth can reduce the pain during childbirth or even make it disappear, so many pregnant women want to do it.

In fact, painless delivery injections can greatly reduce the pain of childbirth for pregnant women, but they are not suitable for all pregnant women.

1. For the fetus

If the dose is not large, which is equivalent to about 1/10 of the dose used in caesarean section, it is not easy to enter the fetus through the umbilical cord blood, so it will not have any major impact on the fetus. However, you must do a physical examination first and get the injection under the guidance of a doctor.

2. For pregnant women

There are some risks! There may be some complications, such as low blood pressure and mild headaches. If you are allergic to the drug, it may induce allergies. In addition, because the painless delivery injection is given from the waist, if you have a history of waist trauma, you should take the initiative to consult a doctor, and the doctor will decide whether you can get it. After delivery, depending on the person, you may experience back pain. These may be side effects of the drug. You can consider using a hot towel for heat treatment to relieve the symptoms.

3. For the delivery process

Adverse reactions mainly affect the labor process and placental blood supply. According to different individuals and different physical conditions, you can choose according to the professional advice of the doctor. Only when it is suitable for you can you minimize the harm.

In order to reduce the pain of women during childbirth, painless delivery has appeared at home and abroad. Some mothers who can't stand the pain of childbirth will choose painless delivery. For painless delivery, you have to wait until the cervix is ​​open to four fingers before you can start injecting anesthetics. You should pay special attention to this time. If it is too early, you may be afraid of affecting the opening, and if it is too late, you may be afraid of being too late. The pain before opening to four fingers still needs to be endured by mothers, of course, this is definitely much less than the pain of natural delivery. After the cervix is ​​open to four fingers, the doctor will inject an injection into the lumbar spine and insert a tube. The needle is relatively long and thick. Mothers who are afraid of needles should close their eyes during the injection. After the anesthetic needle is injected, it will stop hurting after five minutes, and then after a while, the drug effect will pass, and then inject a little more, and keep pushing the anesthetic into the spine. After the anesthetic injection, mothers can chat, watch TV or sleep to save their energy. When the cervix is ​​open to eight fingers, mothers can start to give birth with all their strength. However, it is not suitable to give anesthesia injections when the baby is eight fingers long, and mothers still have to endure the pain of labor. It can be seen that painless childbirth is not completely painless, but it can still reduce the pain of labor to a great extent. It can also allow pregnant women to have some time to catch up on sleep and rest, so that they have enough physical strength to give birth to the baby quickly. However, painless childbirth is not suitable for every woman, so when using painless childbirth, you should consult a professional doctor in advance and follow the doctor's opinions and suggestions.

The current labor analgesia methods include two categories: non-drug analgesia and drug analgesia. Non-drug analgesia includes psychological comfort, breathing, water birth, etc. Its advantage is that it has no effect on the labor process and the fetus, but the analgesic effect is poor; drug analgesia includes nitrous oxide inhalation, intramuscular injection of analgesics, and spinal analgesia. Spinal analgesia is the most accurate method of analgesia among all labor analgesia methods so far. This operation is performed by experienced anesthesiologists. After the anesthesiologist successfully punctures the lumbar intervertebral space, a small amount of local anesthetic or opioid is injected into the subarachnoid space, and a thin catheter is inserted into the epidural space. One end of the catheter is connected to an electronic analgesia pump, and the parturient controls the medication according to the degree of pain (the anesthesiologist has set a limit per hour, so there is no need to worry about overdose). The analgesia pump can be used continuously until the end of labor. During the whole process, the concentration of anesthetics is low, equivalent to 1/5 to 1/10 of that during cesarean section anesthesia. It is highly controllable and safe, and has almost no effect on the movements of the parturient. The parturient is conscious and can actively cooperate and participate in the whole delivery process. When giving parturients labor analgesia, the principle of not affecting the labor process and fetal safety should be considered. By strictly administering analgesics and not affecting the regular contraction of the uterus, the transmission of pain nerves during labor can be blocked, thereby achieving the purpose of avoiding or alleviating the pain of labor and minimizing the pain of labor, but retaining uterine contraction and slight pain.

1. Uterine weakness (early onset). Uterine weakness is the most common cause of postpartum hemorrhage. After the placenta is detached, the small blood vessels in the uterus need to rely on the good contraction of the uterine muscle layer to compress the blood vessels and form local blood clots to achieve the effect of hemostasis. If in some special circumstances, such as: excessive amniotic fluid, giant babies, multiple births, etc., the uterus is too dilated, and the uterus is fatigued due to too long labor induction or too long labor, it will affect the contraction and lochia volume.

2. Retention of the placenta in the uterus (early or late onset). The placenta is where the fetus obtains nutrients from the mother and is tightly attached to the inner wall of the uterus. After the fetus is delivered, the pressure in the uterus drops rapidly, and oxytocin stimulates uterine contraction, blocking the blood flow to the placenta, which can cause the placenta to detach soon after the fetus is delivered. But sometimes the placenta does not fall off completely, or there is varying degrees of placental implantation, or an extra "accessory placenta" grows, which may cause part of the placenta to remain in the uterus.

3. Birth canal laceration. Birth canal laceration is another common cause of postpartum hemorrhage. The entire birth canal (including the lower uterine segment, cervix, vagina and vulva) and even adjacent organs (such as bladder, rectum and anus) may be injured and bleed during delivery.

4. Uterine inversion. Because the placenta is too tightly attached, if the uterus contracts poorly and the placenta grows on the top of the uterus, when the doctor pulls the umbilical cord to pull out the placenta, the top of the uterus may sink into the uterine cavity. In severe cases, the entire uterus may turn out of the vagina. Although uterine inversion is rare, the sequelae may be very serious. Once it cannot be pushed back, the mother may bleed profusely and her life may be in danger.
