Repeated variable decelerations of fetal heart rate during labor typically indicate what condition?

• A. Normal variations
• B. Umbilical cord occlusion
• C. Uteroplacental insufficiency
• D. Maternal stress

Answer: (B)

Repeated variable decelerations of fetal heart rate during labor are primarily associated with umbilical cord occlusion. This condition occurs when the umbilical cord is compressed, which can reduce blood flow and oxygen to the fetus. As a result, the fetal heart rate may show repetitive deceleration patterns corresponding to each contraction. These decelerations can be characterized by their abrupt onset and recovery, which aligns with the timing of the contractions when the cord compression happens. In contrast, normal variations in fetal heart rate do not typically lead to decelerations or indicate an underlying issue. Uteroplacental insufficiency is more commonly associated with late decelerations rather than variable ones, while maternal stress may lead to other changes in fetal heart rate but does not directly cause repeated variable decelerations. Therefore, understanding that umbilical cord occlusion is the key cause of these specific deceleration patterns is vital for effective monitoring and management during labor.
