RENAL IMPLICATIONS OF INCREASED INTRA-ABDOMINAL PRESSURE: ARE THE KIDNEYS THE CANARY FOR ABDOMINAL HYPERTENSION?

AbstractIntroduction: Increased intra-abdominal pressure (IAP) or intra-abdominal hypertension (IAH) is a cause of organ dysfunction in critically ill patients and is independently associated with mortality. The kidneys seem to be especially vulnerable to IAH induced dysfunction and renal failure is one of the most consistently described organ dysfunctions associated with IAH. The aim of this paper is to review the historical background, awareness, definitions, pathophysiologic implications and treatment options for IAP induced renal failure.Methods: This review will focus on the available literature on IAH-induced renal dysfunction. A Medline and PubMed search was performed in order to find an answer to the question “What is the impact of increased IAP on renal function in the critically ill?”. The resulting references were included in the current review on the basis of relevance and scientific merit.Results: Renal dysfunction in IAH is a multifactorial process. The mechanisms involved have not been clar...
