Overview
Secondary peritonitis, often resulting from intra-abdominal infections, is associated with high complication rates including sepsis and multi-organ dysfunction, posing significant clinical challenges 1.Diagnosis
Clinical signs include abdominal pain, tenderness, and signs of systemic inflammatory response syndrome (SIRS) 13.
Laboratory tests: Elevated white blood cell count, C-reactive protein (CRP), and procalcitonin levels 13.
Imaging: Abdominal CT scans may reveal peritoneal thickening, fluid collections, and abscesses 1.
Diagnostic laparoscopy or laparotomy for definitive diagnosis and source control 2.Management
Source Control: Early surgical intervention for necrotic tissue debridement and abscess drainage 2.
Antibiotics: Broad-spectrum empirical therapy tailored based on culture results; consider coverage for common pathogens like gram-negative bacilli and anaerobes 13.
Supportive Care: Intensive care unit (ICU) monitoring, fluid resuscitation, and management of organ dysfunction using Sequential Organ Failure Assessment (SOFA) scores 35.
Inflammatory Modulation: Monitor and manage hyperinflammatory states; consider anti-inflammatory strategies in severe cases 46.Special Populations
Elderly: Higher risk of complications and poorer outcomes; close monitoring of organ function and tailored antibiotic therapy 3.
Comorbidities: Presence of comorbidities like arterial hypertension can complicate management; individualized care plans are essential 2.Key Recommendations
Perform early surgical intervention for source control in secondary peritonitis to improve outcomes (Evidence: Moderate 2).
Utilize SOFA scores for daily assessment of organ dysfunction to guide management and predict prognosis (Evidence: Moderate 3).
Tailor antibiotic therapy based on clinical presentation and local pathogen prevalence, aiming for early de-escalation (Evidence: Moderate 13).
Closely monitor elderly patients and those with comorbidities for increased risk of adverse outcomes and adjust care accordingly (Evidence: Moderate 23).References
