What are Decels in labor?
Decelerations are temporary drops in the fetal heart rate. There are three basic types of decelerations: early decelerations, late decelerations, and variable decelerations. Early decelerations are generally normal and not concerning. Late and variable decelerations can sometimes be a sign the baby isn’t doing well.
What happens when baby heart rate drops during labor?
This can cause sudden, short drops in fetal heart rate, called variable decelerations, which are usually picked up by monitors during labor. Cord compression happens in about one in 10 deliveries. In most cases, these heart rate changes are of no major concern, and the birth proceeds normally.
Which decelerations occur with contractions?
Early Deceleration[1][8]: Visually apparent gradual decrease and return of the fetal heart rate associated with a uterine contraction. Time from onset to nadir is 30 seconds or more. The nadir occurs at the same time as the peak of the contraction. This is usually considered a benign result of fetal head compression.
What causes fetal heart rate decelerations?
What causes early deceleration? Early decelerations are caused by compression of the fetal head during uterine contractions. This results in vagal response (a response that occurs when the vagus nerve is stimulated). The vagal response causes a drop in the fetal heart rate.
What causes late decelerations in labor?
Late decelerations are one of the precarious decelerations among the three types of fetal heart rate decelerations during labor. They are caused by decreased blood flow to the placenta and can signify an impending fetal acidemia.
What do early decelerations indicate?
Early decelerations in FHR are caused by compression of the fetus’s head during a uterine contraction. As the uterine muscles get tighter and shorter, the size of the uterus decreases, thereby limiting the available space for the fetus.
What causes fetal heart rate drop?
A slow fetal heart rate is typically caused by problems with the heart’s electrical system, which sends out electrical impulses that signal the heart muscles to contract or beat. The problem can occur in the sinus node, the heart’s natural pacemaker, where these electrical impulses are generated.
What are appropriate nursing interventions for FHR decelerations?
Interventions for late decelerations are:
- Lower the head of the bed and turn the mom on her left side to take the pressure off the vena cava and allow blood flow to the heart and to the lungs.
- Re-oxygenation or the reintroduction of oxygen to the baby by giving oxygen to the mother.
What causes fetal bradycardia during labor?
Fetal bradycardia can be caused by any event or delivery complication that puts the baby under physical stress and/or restrict the flow of oxygen to the baby. Complications that can potentially cause bradycardia include: umbilical cord prolapse, placental abruption, and uterine rupture.
What are the nursing interventions for early decelerations?
Some nursing interventions include: turn mom onto her side, stop Picotin if infusing, administer 10 L of O2, maintain IV access, determine the Fetal Heart Rate variability, and contact doctor.
