What Causes Tetanic Uterine Contractions

Tetanic uterine contractions can be a serious concern for pregnant women, and understanding what causes them is important for proper management. These forceful contractions can be harmful to both the mother and the baby, and without proper care, they can lead to complications during delivery. In this article, we’ll take a closer look at what causes tetanic uterine contractions and how they can be managed.

What are Tetanic Uterine Contractions?

Tetanic uterine contractions, also called “uterine tetany,” is a condition where the muscles of the uterus contract rapidly and forcefully. These contractions are different from the normal contractions that occur during labor, and they can be much stronger and more frequent. The contractions can occur at any time during pregnancy, but they are most often seen in the third trimester.

Symptoms of Tetanic Uterine Contractions

The symptoms of tetanic uterine contractions can vary depending on the severity of the condition. Some women may experience mild contractions that are easy to manage, while others may experience severe contractions that require immediate medical attention. Some common symptoms include:

– Painful, frequent contractions

– Tightness in the abdomen

– Back pain

– Vaginal bleeding

– Decreased fetal movement

Causes of Tetanic Uterine Contractions

There are a number of factors that can cause tetanic uterine contractions. Some of the most common causes include:

– Dehydration: Dehydration can cause an electrolyte imbalance in the body, which can lead to uterine contractions.

– Infection: Infections during pregnancy can cause inflammation in the uterus, which can lead to contractions.

– Preterm labor: Women who are at risk for preterm labor may experience tetanic uterine contractions as a sign of early labor.

– Preeclampsia: This condition is characterized by high blood pressure and can cause tetanic uterine contractions.

– Fetal distress: When the baby is in distress, the uterus may contract in an attempt to deliver the baby quickly.

Management of Tetanic Uterine Contractions

The management of tetanic uterine contractions will depend on the severity of the condition. Some mild contractions can be managed at home with rest and hydration, while more severe cases may require hospitalization. In some cases, medication may be used to control the contractions and prevent preterm labor.

Prevention is also an important aspect of managing tetanic uterine contractions. Pregnant women should stay hydrated, eat a healthy diet, and avoid risky behaviors that can lead to infection. Regular prenatal care is also important to monitor the health of the mother and the baby.


Tetanic uterine contractions can be a serious concern during pregnancy, but with proper management, they can be controlled. Understanding the causes of these contractions is important for preventing and managing the condition. If you are experiencing frequent or severe contractions, it is important to seek medical attention right away. With proper care, you can ensure a healthy delivery for yourself and your baby.
