What corrective measure may be used for variable decelerations of fetal heart rate?

Variable decelerations in fetal heart rate are often caused by cord compression, which can impede blood flow and result in changes to the fetal heart rate patterns. Amnioinfusion is a procedure that involves the introduction of a sterile fluid (usually saline) into the amniotic cavity through an intrauterine catheter. This technique can help alleviate compression of the umbilical cord by increasing the volume of amniotic fluid, which acts as a cushion and reduces the pressure on the cord during contractions. By addressing the root cause of variable decelerations, amnioinfusion can help stabilize the fetal heart rate and improve oxygenation.

Position change can also be beneficial, as certain maternal positions may relieve pressure on the umbilical cord. However, amnioinfusion directly targets the issue at its source, making it a more specific corrective measure for this type of deceleration. The fluids bolus is used primarily for hydration and improving maternal blood volume but does not specifically address cord compression issues. Surfactant therapy is utilized for pulmonary complications, particularly in premature infants, but does not relate to the management of fetal heart rate decelerations. Therefore, amnioinfusion is the most appropriate and effective intervention for managing variable decelerations of fetal
