abdominal hypertension

Sustained intra-abdominal pressure ≥12 mmHg, a precursor to abdominal compartment syndrome requiring monitoring and intervention.

Full Definition

Abdominal hypertension is defined as sustained intra-abdominal pressure (IAP) of 12 mmHg or higher, measured at end-expiration in the supine position. It is classified into grades: Grade I (12-15 mmHg), Grade II (16-20 mmHg), Grade III (21-25 mmHg), and Grade IV (>25 mmHg). Abdominal hypertension can progress to abdominal compartment syndrome when IAP exceeds 20 mmHg with new organ dysfunction. Common causes include massive fluid resuscitation, bowel obstruction, abdominal surgery, and trauma. Management includes medical measures to reduce IAP and prevention of progression to compartment syndrome.

Usage

Usage note: Always include pressure measurements and grading when documenting.
