Final answer:
When encountering late decelerations with maternal hypotension, interventions such as administering oxygen, increasing IV fluid rate, and changing maternal position should be promptly considered to enhance uteroplacental perfusion and fetal oxygenation.
Step-by-step explanation:
When late decelerations in fetal heart rate are associated with maternal hypotension, the primary focus is to improve uteroplacental perfusion and, in turn, increase oxygenation to the fetus. The appropriate interventions include:
- Administer oxygen to the mother to improve fetal oxygenation.
- Increase the intravenous (IV) fluid rate to enhance maternal blood volume and blood pressure, potentially helping with perfusion.
- Change the maternal position, preferably to a side-lying position, to decrease the pressure on the vena cava and improve blood flow.
- Administering a tocolytic medication may be considered if uterine hyperstimulation is contributing to the decelerations, though this is not the first line of action for decelerations associated with maternal hypotension.
It is essential to assess the situation quickly and respond appropriately to alleviate potential fetal distress and optimize maternal-fetal circulation.
