What purpose does amnioinfusion serve during pregnancy?

Amnioinfusion is a procedure typically performed during labor when there are concerns about the amount of amniotic fluid present. Its primary purpose is to manage oligohydramnios, which is a condition characterized by low amniotic fluid volume. By introducing a sterile fluid (usually saline) into the amniotic cavity via a catheter, the procedure helps to increase the volume of amniotic fluid. This increase can have several beneficial effects, such as reducing the risk of umbilical cord compression, improving fetal heart rate patterns, and potentially aiding in better fetal monitoring.

While it can also serve the purpose of increasing amniotic fluid volume, the main focus in the context of clinical practice and the management of labor is on addressing the complications associated with oligohydramnios. Therefore, the role of amnioinfusion as a direct intervention specifically for oligohydramnios underscores its clinical significance in ensuring better fetal outcomes during labor, making management of this condition the most accurate description of its purpose.
