Endomyometritis is a postpartum uterine infection that can lead to significant morbidity and mortality if not promptly recognized and managed. This case describes a 25-year-old primiparous patient with endometritis and how her condition was evaluated and managed. Endomyometritis is a clinical diagnosis. Key to the management is early introduction of antibiotics. If fevers persist, further evaluation is necessary to exclude alternative sources of infection. Early consideration of sepsis is crucial, and scoring systems can aid in identifying patients at risk for severe morbidity. Prevention strategies include reducing vaginal exams, minimizing the time between rupture of membranes and delivery, and implementing surgical bundles and prophylactic antibiotics for cesarean deliveries.
