Background

  • Organ dysfunction caused by intrabdominal hypertension
  • Increased intrabdominal pressure resulting in decreased organ perfusion, impaired hemodynamics

Pathophysiology

  • Abdominal perfusion pressure = MAP - intrabdominal pressure
  • Build up of fluid or blood within the peritoneum or retroperitoneum
    • And/or decrease in abdominal wall compliance
  • Increased pressure within cavity of fixed volume → hypoperfusion of abdominal organs
    • Also causes restriction of diaphragmatic excursion and impaired central venous return

Causes

Clinical Features

Differential Diagnosis

Abdominal Trauma

Evaluation

Physical exam is neither sensitive nor specific

  • Obtain bladder pressure
    • Measurement >20mmHg WITH new organ dysfunction is indicative of compartment syndrome

Management

Nonoperative

Often first line approach when no abdominal injury present[1]

Operative

Definitive treatment

  • Laparotomy provides decompression
    • High complication rate
    • No guidelines for timing of closure

Disposition

  • Admit
