It's normal to feel a little scared and worried if your doctor does a scan during pregnancy and says, "There's a little less water around the baby." Or what if the baby's heartbeat slows down a bit during labor and you're told it's because of a lack of water? In these cases, we're going to talk about a special and important treatment that doctors use to help both mother and baby.
Simply put, what is Amnioinfusion?
Amnioinfusion is a procedure that restores the amount of amniotic fluid that has been depleted by injecting a special fluid into your uterus, where your baby is. Simply put, it is giving your uterus a saline-like fluid. This involves infusing saline or lactated Ringer's solution into your uterus using a thin tube called a catheter . This replenishment of the lost fluid helps stabilize your baby's heart rate and prevent the baby from getting too little oxygen.
Before understanding this treatment, let's also know about these things
Before we talk further about this treatment, let's briefly discuss two important points in this regard.
What is Amniotic Fluid?
Amniotic fluid is a protective fluid that surrounds the baby in the womb. It acts like a protective cushion for the baby. This fluid protects the baby from infections, protects the umbilical cord from compression, and helps the baby move around in the womb without any problems. In addition, this amniotic fluid is essential for the development of the baby's respiratory and digestive systems, and for regulating body temperature. So if there is not enough of this fluid, it can affect the baby's health as well as the delivery.
What is the Umbilical Cord?
The umbilical cord is the lifeline of the baby inside the womb. It is this that connects the baby to the placenta. The baby receives the oxygen, nutrition, and blood it needs through this umbilical cord. So, when the amniotic fluid decreases, this umbilical cord can become compressed. If that happens, the oxygen and nutrition that the baby receives is impaired, and the baby can become uncomfortable (fetal distress).
In what cases is amnioinfusion treatment necessary?
This treatment is not for everyone. Doctors only use it in a few selected cases. Let's see what it is.
| Condition | Description |
|---|---|
| Low amniotic fluid (Oligohydramnios) | This is the main reason. This treatment is considered if the amount of water around the baby is lower than normal . |
| Umbilical Cord Compression | When the amniotic fluid is low, the umbilical cord can become compressed. This causes the baby's heart rate to change. When the fluid is inserted, the umbilical cord is allowed to float freely. |
| To prevent premature birth (Preterm Premature Rupture of Membranes) | Sometimes, the water can break prematurely. If this happens, especially in the early months of pregnancy, fluid is injected into the uterus to create a suitable environment for the baby to stay in the womb for a while longer. |
| To prevent meconium aspiration syndrome | Meconium is the first stool that a baby passes in the womb. It can mix with the amniotic fluid. It is more dangerous if the baby swallows it, but it can also be inhaled. Amnioinfusion reduces this risk by diluting the meconium. |
The most important thing is for your doctor to decide whether you need this treatment or not, and what its advantages and disadvantages are, based on your health condition.
Are there any cases where amnioinfusion should not be performed?
Yes, in some cases this treatment is not appropriate because it is safer to deliver the baby sooner rather than treat it at that time.
- If the baby is in serious fetal distress, this treatment cannot be delayed by even a few minutes.
- If you have an active infection, such as genital herpes, or another infection of the uterus.
- If you have a low-lying placenta (placenta previa) or if there is a suspicion of placental abruption.
- If the baby is in a breech or other unusual position, rather than head down.
How is this treatment done?
This may sound a little scary, but it's done very systematically.
First, the doctor will make sure that the baby is in the head-first position. Your cervix should also be at least 1-2 centimeters dilated.
Then, a special tube called an Intrauterine Pressure Catheter (IUPC) is inserted into the uterus. This tube is connected to several devices. One measures the baby's heartbeat, another measures uterine contractions, and the third injects saline solution.
A room-temperature saline solution is slowly inserted into the uterus for 10 to 30 minutes. During this time, doctors and nurses will monitor you and your baby closely. You may feel some discomfort or pain after the treatment, which is normal.
What are the benefits of amnioinfusion treatment?
In addition to restoring the baby's heartbeat, this treatment has several other benefits.
- Reduced risk of having a cesarean section (C-section).
- Reduced need for the use of instruments such as forceps or vacuum.
- Improving the flow of blood and oxygen to the baby through the umbilical cord.
- Helping to delay labor slightly to prevent complications from premature birth.
- Reducing the concentration of meconium-stained amniotic fluid.
- The baby's Apgar scores - a measure of the baby's health after birth - are high.
- Reduced risk of postpartum endometritis, which can occur due to the lack of amniotic fluid.
Are there any risks or complications with this?
Overall, amnioinfusion is a safe and effective procedure. However, like any medical procedure, there are some risks. These are very rare.
| Risk / Complication | Description |
|---|---|
| Chorioamnionitis | Infection of the placenta and amniotic fluid. |
| Umbilical cord prolapse | The umbilical cord coming down through the cervix. This is an emergency. |
| Polyhydramnios | An increase in the amount of amniotic fluid in the uterus. |
| Uterine overdistention | The uterus becomes enlarged due to increased fluid. |
| Uterine perforation | Very rarely, damage to the uterine wall due to the catheter. |
Your doctor will inform you of all these risks and monitor you carefully during and after treatment.
Take-Home Message
- Amnioinfusion is a treatment that replenishes the amniotic fluid level during or before labor by injecting a saline-like fluid into the uterus.
- The main goals of this are to prevent umbilical cord compression, restore the baby's heartbeat, and ensure the baby's oxygen supply.
- Although this is generally a safe procedure, as with all medical procedures, there are some minor risks.
- If you feel like you're leaking fluid from your vagina during pregnancy, see your doctor immediately to find out if it's a vaginal discharge.
- If you have any questions about this treatment or your serum calcium levels, don't hesitate to talk to your doctor. He or she will explain everything to you.
