Abdominal compartment syndrome

Abstract

Abdominal compartment syndrome (ACS) is a devastating condition for the critically unwell patient. Initially described as solely affecting surgical patients, ACS is now also recognized in the medical intensive care setting. Without prompt and definitive treatment mortality rates approach 70% as multi-organ failure develops. Over the past decade our understanding, recognition and management of ACS has evolved. The World Society of Abdominal Compartment Syndrome published updated guidelines in 2013 to draw consensus and improve patient outcomes. ACS is the end sequela of raised intra-abdominal pressure (IAP), defined as a sustained IAP >20 mmHg with or without an abdominal perfusion pressure <60 mmHg and associated with new organ dysfunction. Intravesical measuring of IAP is the gold standard diagnostic technique. Surgical decompressive laparotomy and open abdomen with temporary abdominal closure measures is the definitive treatment. This article summarizes the updated consensus definitions, pathophysiology, diagnostic investigation and management to help the junior surgical trainee faced with ACS.
