Which treatment may be considered in the management of prolonged decelerations to improve fetal oxygenation?

Amnioinfusion is a treatment option that can be beneficial in the management of prolonged decelerations during labor. It involves the introduction of a sterile fluid solution into the amniotic cavity through a catheter placed in the uterus. This procedure is particularly effective in cases where the umbilical cord is compressed, which can lead to decreased fetal oxygenation and result in characteristic fetal heart rate decelerations.

By diluting the amniotic fluid, amnioinfusion can alleviate cord compression and improve perfusion to the fetus, thereby enhancing oxygenation. This therapeutic approach is primarily used when there is evidence of variable decelerations, which are often due to cord compression. In such scenarios, relieving the pressure on the cord can directly facilitate better fetal oxygen delivery.

While intravenous fluids may support maternal hydration and overall circulation, they do not directly address the fetal condition. The administration of steroids is typically utilized to promote fetal lung maturity in cases of preterm labor, but it does not provide immediate relief from oxygenation issues caused by decelerations. Triggering uterine contractions may actually exacerbate the issue by increasing uterine tone and potentially compressing the umbilical cord further.

Therefore, the use of amnioinfusion stands out as a targeted
