Oligohydramnios refers to a condition in which the amount of amniotic fluid surrounding the fetus is reduced.
The diagnosis is made through ultrasound measurements and evaluations.
A normal amount of amniotic fluid is essential for the healthy development of fetal organ systems, particularly the lungs.
Amniotic fluid provides a sterile and protective environment, shielding the baby from external trauma and harmful influences.
Amnioinfusion Procedure
When certain conditions are met—specifically in the absence of active fluid leakage or infection—it is possible to restore the missing fluid by injecting a sterile solution into the uterus under ultrasound guidance.
This procedure is called amnioinfusion.
In some cases, when there is uncertainty about the cause of fluid loss, amnioinfusion may be performed during a detailed ultrasound scan to clarify the situation.
The procedure can help to:
- Provide a clearer assessment of potential structural anomalies,
- Support fetal lung development,
- Prevent positional deformities caused by reduced intrauterine space.
Intrapartum (During Labor) Applications
During labor, continuous fetal heart rate monitoring is performed.
In certain situations, a catheter may be used to infuse sterile fluid into the uterus via the vaginal route to reduce risk, such as:
- When there is significant umbilical cord compression,
- In the presence of thick meconium-stained amniotic fluid (indicating the baby has passed meconium before birth).
This intervention aims to maintain adequate fetal oxygenation and reduce complications during delivery.
