What is the primary purpose of performing an amnioinfusion?

The primary purpose of performing an amnioinfusion is indeed to alleviate variable decelerations in the fetus. Variable decelerations are often caused by umbilical cord compression, which can occur due to oligohydramnios (low amniotic fluid levels) during labor. By introducing a sterile fluid (usually normal saline) into the amniotic cavity through an intrauterine catheter, amnioinfusion increases the volume of amniotic fluid. This added fluid can help cushion the umbilical cord, reducing the pressure exerted on it during contractions. As a result, the risk and severity of variable decelerations can decrease, promoting better fetal oxygenation and overall fetal well-being.

The other options do not align with the primary goal of amnioinfusion. For example, enhancing fetal movement is not a direct aim of this procedure, nor is increasing uterine contractions; these elements are generally managed through other interventions. While promoting fetal monitoring may be a secondary benefit, the essential focus of amnioinfusion remains on addressing the issues related to umbilical cord compression and improving fetal heart rate patterns.
