What this trial studies

This clinical trial investigates the effectiveness of oral antibiotics in patients with acute mesenteric ischemia (AMI), a serious condition that can lead to intestinal necrosis. Eligible participants will be randomly assigned to receive either gentamicin and metronidazole or a placebo, with evaluations conducted at multiple time points post-randomization. The study aims to determine if early antibiotic intervention can improve survival rates and reduce the need for surgical resection. Conducted at the SURVI unit in Beaujon Hospital, this trial represents a novel approach to managing AMI.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 90 diagnosed with acute mesenteric ischemia of arterial occlusive origin.

Not a fit: Patients with other forms of mesenteric ischemia or those not eligible for intensive care or surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve survival rates and reduce complications for patients with acute mesenteric ischemia.

How similar studies have performed: While this approach is novel, preliminary pilot studies have shown promising results in improving survival and reducing surgical interventions.
