Perforated Peptic Ulcer with Healthcare-Associated Intra-Abdominal Infection in a Critically Ill Patient with Normal Renal Function

Clinical Scenario

This protocol applies to perforated peptic ulcer complicated by healthcare-associated intra-abdominal infection (IAI) in a critically ill patient with normal renal function. The healthcare-associated origin of infection and the severity of illness together define the pathogen risk profile and shape antibiotic selection for this population.

Treatment Approach

Empiric treatment involves a broad-spectrum carbapenem combined with a glycopeptide; risk-stratified adjustments apply in certain patients, and the complete selection algorithm is in the full protocol.

Clinical Goals

The primary target is normalization of inflammatory markers, guided by a short-course antibiotic approach.
