Abdominal Compartment Syndrome (ACS) causing AKI

ICD-10 Code
T79.A2

Oliguric AKI caused by intra-abdominal hypertension (IAP >20 mmHg), which directly compresses the renal veins, increasing renal interstitial pressure and drastically reducing glomerular filtration gradient.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with acute oliguria/anuria in the setting of progressive abdominal distension. History significant for [e.g., massive fluid resuscitation, ileus, or trauma]. Current IAP measured at [X] mmHg. Symptoms consistent with ACS-induced AKI, characterized by rapid decline in GFR due to renal venous congestion and elevated interstitial pressure.

Clinical Examination Findings

Patient appears in distress, tachypneic, and tachycardic. Abdomen is tense, distended, and tympanitic to percussion. Signs of systemic hypoperfusion noted. Bladder pressure monitoring confirms intra-abdominal hypertension. Peripheral edema may be present due to venous return impairment.

Treatment Protocol

Immediate management includes: 1) Optimization of abdominal perfusion pressure (APP = MAP - IAP). 2) Decompression via NG tube/rectal tube or paracentesis. 3) Judicious fluid management to avoid further bowel edema. 4) Consider surgical decompression (laparotomy) if IAP >20 mmHg with organ dysfunction. 5) Renal replacement therapy (CRRT) if refractory AKI persists.
