Abdominal Compartment Syndrome Diagnosis and Management
Patient Selection for Monitoring
- The World Society of the Abdominal Compartment Syndrome recommends intra-abdominal pressure (IAP) monitoring in patients at risk of intra-abdominal hypertension, particularly those with severe abdominal trauma, massive fluid resuscitation, or burns >30% TBSA, to enable early detection of abdominal compartment syndrome (ACS) which carries a 90% mortality if untreated 1, 2
- Severe abdominal trauma patients (AIS ≥3) admitted to ICU, especially those undergoing non-operative management, should be monitored 1, 2, 3
Monitoring Technique and Frequency
- The World Society of the Abdominal Compartment Syndrome recommends protocolized IAP monitoring in at-risk patients 4, 5, 6
- Measure compartment pressures every 30 minutes to 1 hour during the first 24 hours in high-risk patients 3
- Continue continuous monitoring for at least the first 24 hours, followed by clinical and biological observation for a minimum of 3-5 days 1, 2, 3
Diagnostic Criteria and Clinical Manifestations
- Abdominal compartment syndrome is defined as IAP >25 mmHg associated with any organ dysfunction and requires emergent treatment 1, 2, 3, 7
- Alternative diagnostic criteria include: IAP >30 mmHg with clinical signs of ACS 8
- Monitor for the following organ dysfunctions indicating ACS: Respiratory, Renal, Cardiovascular, Abdominal, Neurologic 1, 3
Management Algorithm
- The World Society of the Abdominal Compartment Syndrome suggests the following interventions: Avoid sustained intra-abdominal hypertension through protocolized management, Limit positive fluid balance after initial patient resuscitation, Consider percutaneous catheter drainage for fluid collections, Optimize body positioning, Use enhanced ratios of plasma to red blood cells during resuscitation 4, 5, 6
- Decompressive laparotomy is the definitive treatment for fully developed ACS and should be performed emergently 4, 5, 6
Special Considerations
- ACS typically occurs within 12-13 hours after primary laparotomy in trauma patients 1, 2, 3
- 95% of delayed hemorrhagic complications occur within the first 72 hours, with maximum risk in the first 24 hours 1, 2, 3
- Patients with severe abdominal trauma undergoing non-operative management must be admitted to institutions with 24/7 capacity to perform emergency hemostatic laparotomy 1, 2, 3, 7
