Elevated Intra-abdominal Pressure and Renal Function

Elevated intra-abdominal pressure in acute decompensated heart failure: a potential contributor to worsening renal function?

OBJECTIVES This study sought to determine whether changes in intra-abdominal pressure (IAP) with aggressive diuretic or vasodilator therapy are associated with improvement in renal function in acute decompensated heart failure (ADHF). BACKGROUND Elevated IAP (>or=8 mm Hg) is associated with intra-abdominal organ dysfunction. There is potential for ascites and visceral edema causing elevated I...

Effects of increased intra-abdominal pressure and volume expansion on renal function in the rat.

BACKGROUND The effects of increased intra-abdominal pressure (IAP) and volume expansion on renal function in the rat were studied to gain more knowledge of the oliguria seen during laparoscopic procedures and to reduce the detrimental renal effects of IAP. METHODS IAP was elevated to 5 or 10 mmHg by insufflation of CO(2) and maintained for 2 h in anaesthetized and mechanically ventilated rats...

Intra-abdominal pressure, intra-abdominal hypertension, and pregnancy: a review

The last several decades have seen many advances in the recognition and prevention of the abdominal compartment syndrome (ACS) and its precursor, intra-abdominal hypertension (IAH). There has also been a relative explosion of knowledge in the critical care, trauma, and surgical populations, and the inception of a society dedicated to its understanding, the World Society of the Abdominal Compart...

The Effect of Increased Intra-abdominal Pressure on Renal Function in Man.

Intra-abdominal pressure and abdominal wall muscular function: Spinal unloading mechanism.

BACKGROUND The roles of antagonistic activation of abdominal muscles and of intra-abdominal pressurization remain enigmatic, but are thought to be associated with both spinal unloading and spinal stabilization in activities such as lifting. Biomechanical analyses are needed to understand the function of intra-abdominal pressurization because of the anatomical and physiological complexity, but p...
