BACKGROUND AND AIMS
Increased intra-abdominal pressure (IAP), also referred to as intra-abdominal hypertension (IAH), affects organ function in critically ill patients. The prevalence of IAH is between 32% - 65% in intensive care units. Normal IAP is ≈ 5–7 mmHg. According to WSACS definition, IAH = IAP ≥12 mmHg and is divided into 4 grades. They are Grade I (12-15 mmHg), Grade II (16-20 mmHg), Grade III (21-25 mmHg), Grade IV (>25 mmHg). Transvesical measurement of IAP currently is the most popular technique. Several systems with or without the need for electronic equipment are available that allow IAP measurement. The aim is to study the incidence of IAH in critically ill patients, to assess the risk factors for development of IAH, to study the role of IAH as a risk factor for Acute Kidney Injury (AKI), to assess the role of IAH as a risk factor for increased (Intensive Care Unit) ICU mortality.
SUBJECTS AND METHODS
This is a prospective observational study. Study period was six months. The study included 52 patients admitted to Medical ICU in Government Medical College, Kozhikode, Kerala.
RESULTS AND CONCLUSION
There was a very high incidence of intra-abdominal hypertension in critically ill patients. IAH was significantly associated with risk factors like sepsis, mechanical ventilation, pancreatitis, capillary leak, ascites, cumulative fluid balance and cirrhosis. IAH is an independent risk factor for development of acute kidney injury. IAH is an independent predictor of mortality in critically ill patients.
