Final answer:
If variable decelerations persist after initial nursing interventions, an emergency birth with interventions such as vacuum extraction, forceps, or Caesarian section might be necessary. Post-delivery, treatments like intubation and CPAP may be used, especially in cases of RDS or prematurity.
Step-by-step explanation:
When variable decelerations persist after nursing interventions, further medical procedures may be necessary. Variable decelerations indicate changes in the fetal heart rate that are not consistent with contractions and may signal potential fetal distress. If these decelerations continue despite initial nursing actions, such as changing the mother's position or ensuring adequate hydration and oxygenation, more acute measures need to be considered for the safety of both mother and fetus. An emergency birth may be required, utilizing methods such as vacuum extraction, forceps delivery, or a Caesarian section. These procedures are expedited when there is evidence of continual fetal distress. The immediate goal is to deliver the baby and relieve any compression that might be contributing to the decelerations. Additionally, if the infant is born prematurely or with respiratory distress syndrome (RDS), certain treatments such as resuscitation, intubation, and mechanical ventilation, or nasal CPAP might be employed. Administration of pulmonary surfactant, corticosteroids, supplemental oxygen, and assisted ventilation are other possible interventions to improve the newborn's breathing and overall health post-delivery.
