What is a significant risk associated with hypertonic contractions during labor?

During labor, hypertonic contractions are characterized by excessively strong and frequent contractions that do not allow for adequate resting periods in between. The absence of rest periods is significant because it can lead to uterine fatigue, reduced blood flow to the placenta, and impaired oxygen delivery to the fetus. This can pose serious risks for both the mother and the baby, including increased stress on the fetus, which may be reflected in abnormal fetal heart rate patterns.

In addition, the lack of sufficient resting time can also lead to increased pain and a heightened perception of discomfort for the laboring person. This continuous strain on the uterus can complicate labor progression and increase the likelihood of interventions being necessary to assist with delivery.

The other options do hold some relevance to labor complications, but the key risk with hypertonic contractions is primarily tied to the absence of a rest period between each contraction.
