The so-called Weak contractions is a common cause of labor arrest or lack of progress in labor. The Weak contractions is often referred to as labor dystocia. Labor dystocia is defined as a prolonged labor—for example, when the cervix does not dilate or dilates only slowly, when uterine contractions are ineffective or insufficient, too weak and irregular, or even cease entirely.
Primary and Secondary Labor Weakness
There are two different types of labor weakness: primary labor weakness and secondary labor weakness. Primary labor weakness refers to a condition in which labor weakness is already present at the onset of labor. Secondary labor weakness refers to a condition in which labor weakness develops during the course of labor.
Causes of Weak Contractions
There are several causes of weak labor contractions. Causes of primary weak labor contractions may include an overstretched uterus due to multiple pregnancies and large babies, weakness of the uterine muscles, or fibroids. Causes of secondary labor weakness can include a breech or transverse presentation of the baby or overstimulation of the uterus with labor-inducing, anesthetic, or pain-relieving medications. In the case of a breech or transverse presentation, the cervix cannot be sufficiently stimulated due to the abnormal position. As a result, labor contractions are not sufficiently stimulated. As a result, the woman and her muscles become fatigued due to the prolonged labor, and contractions consequently cease.
Treatment for Weak Contractions
The treatment for weak contractions during labor depends on the type and intensity of the contractions. Whenever possible, labor is induced in cases of primary weak contractions. To do this, a gel or tablet is inserted into the cervix to promote cervical dilation. If the cervix is already ready for delivery, the labor-inducing hormone oxytocin is administered via an IV. If secondary labor failure occurs due to exhaustion, the woman should relax and take a short break to rest.
