What is a risk factor for uterine inversion during labor?

The selection of strong traction on the umbilical cord as a risk factor for uterine inversion during labor is grounded in a fundamental understanding of the physiological mechanics involved in childbirth. Uterine inversion occurs when the uterus turns inside out, usually following delivery of the placenta. When excessive force is applied to the umbilical cord, especially during the third stage of labor, it may cause the uterus to pull downward and potentially turn inside out rather than expelling the placenta normally. This can disrupt the natural separation of the placenta, resulting in a more severe risk for inversion.

Having a clear awareness of the specific mechanisms at play during labor, including how improper management of the umbilical cord can lead to complications, is critical for safely guiding the birthing process. While the other factors listed may involve complications associated with labor and delivery, they are not directly linked to the physical mechanics of uterine inversion.
