Background
- Increased intrabdominal pressure resulting in decreased organ perfusion, impaired hemodynamics
- Also known as intrabdominal hypertension (IAH)
Causes
- Trauma
- Diffuse peritonitis
- Small bowel obstruction
- Large volume fluid resuscitation
- Retroperitoneal hemorrhage
- Reperfusion of ischemic bowel
- Acute Pancreatitis
- Ascites
Pathophysiology
- Build up of fluid or blood within the peritoneum or retroperitoneum
- And/or decrease in abdominal wall compliance
- Causes increased pressure within cavity of fixed volume
- Abdominal perfusion pressure = MAP - intrabdominal pressure
- Hypoperfusion of abdominal organs
- Restriction of diaphragmatic excursion
- Impaired central venous return
Clinical Features
- Decreased central venous return
- Increased JVP
- Increased ICP
- Decreased cardiac preload
- Increased intrathoracic pressure
- Decreased lung compliance
- Decreased functional residual capacity
- Worsened V/Q mismatch
- Oliguria, renal failure
- Bowel ischemia
Differential Diagnosis
Diagnosis
- Suspect ACS/IAH
- Transduce bladder pressure
- >20mmHg WITH new organ dysfunction
- Physical exam is neither sensitive nor specific
Management
- Nonoperative: Often first line approach when no abdominal injury present[1]
- Limit fluid resuscitation
- electrolyte repletion
- ABX
- Pressors
- CRRT
- Percutaneous fluid drainage
- Operative: Definitive treatment
- Laparotomy provides decompression
- High complication rate
- No guidelines for timing of closure
- Laparotomy provides decompression
Disposition
- Admit
