What is the Origin of Preterm Labor Prevention?

The term is derived from "preterm labor," which refers to delivery before the full term of pregnancy, and "prevention," indicating measures taken to avert the event. It belongs to the critical domain of maternal-fetal medicine and high-risk obstetrics. The development of effective prevention strategies is a major public health priority.

What is the Mechanism of Preterm Labor Prevention?

The principal hormonal mechanism for prevention involves the administration of progesterone, which acts to maintain uterine quiescence and prevent cervical ripening. Progesterone binds to its receptors in the myometrium, reducing the expression of key contraction-associated proteins and inhibiting the production of pro-inflammatory cytokines and prostaglandins. This powerful anti-contractile and anti-inflammatory action stabilizes the uterine environment, effectively mitigating the risk factors that can lead to the initiation of premature labor.

Preterm Labor Prevention

Meaning

Preterm Labor Prevention encompasses the clinical strategies and medical interventions specifically designed to inhibit or significantly delay the onset of labor before 37 weeks of gestation, aiming to improve the health outcomes for the newborn. These preventative measures are paramount for pregnant women identified as high-risk, such as those with a history of prior spontaneous preterm birth or a short cervix. Hormonal therapy, particularly with progesterone, forms a cornerstone of this preventative clinical approach.
