Fournier Gangrene: A Review for Emergency Clinicians.

BACKGROUND: Fournier gangrene (FG) is a rare, life-threatening infection that can result in significant morbidity and mortality, with many patients requiring emergency department (ED) management for complications and stabilization. OBJECTIVE: This narrative review provides an evidence-based summary of the current data for the emergency medicine evaluation and management of FG. DISCUSSION: Although originally thought to be an idiopathic process, FG has been shown to have a strong association for male patients with advanced age and comorbidities affecting microvascular circulation and immune system function, most commonly those with diabetes or alcohol use disorder. However, it can also affect patients without risk factors. The initial infectious nidus is usually located in the genitourinary tract, gastrointestinal tract, or perineum. FG is a mixed infection of aerobic and anaerobic bacterial flora. The development and progression of gangrene is often fulminant and can rapidly cause multiple organ failure and death, although patients may present subacutely with findings similar to cellulitis. Laboratory studies, as well as imaging including point-of-care ultrasound, conventional radiography, and computed tomography are important diagnostic adjuncts, though negative results cannot exclude diagnosis. Treatment includes emergent surgical debridement of all necrotic tissue, broad-spectrum antibiotics, and resuscitation with intravenous fluids and vasoactive medications. CONCLUSIONS: FG requires a high clinical level of suspicion, combined with knowledge of anatomy, risk factors, and etiology for an accurate diagnosis. Although FG remains a clinical diagnosis, relevant laboratory and radiography investigations can serve as useful adjuncts to expedite surgical management, hemodynamic resuscitation, and antibiotic administration.

The Fournier Gangrene (FG) is a synergistic, polymicrobial, necrotizing fasciitis with infectious origin that produces gangrene of the perineal, genital or perianal skin. The number bigger than cases happens between 20 at 50 years, the males are affected more than the females in proportion 10:1 and the mortality rate is high yet. The clinical manage of the GF must be fast and opportune with intravenous application of fluids, electrolytes and systemic broad-spectrum antibiotic therapy; and avoid the hemodynamic stabilization of the patient before the surgery. The precocious surgery with debridement of the necrotizing tissues constitutes the main objective of the treatment.

La Gangrena de Fournier (GF) es una fascitis necrotizante sinérgica, multimicrobiana, de origen infeccioso, que produce gangrena de piel de región genital, perineal, o perianal. Su mayor frecuencia se observa en pacientes de 20 a 50 años, los varones se afectan más que las hembras en proporción 10:1 y la tasa de mortalidad aún es alta. El manejo clínico debe ser rápido y oportuno, con aplicación intravenosa de líquidos, electrolitos y antibióticos de amplio espectro; a fin de lograr la estabilización hemodinámica del paciente antes de la intervención quirúrgica. La cirugía precoz con debridamiento extenso de tejidos desvitalizados, constituye la base principal del mismo
