BACKGROUND The purpose of the study was to examine hemodynamic parameters and intravascular volume in a porcine model in the presence of intra-abdominal hypertension (IAH) lasting for 24 hours. METHODS Twelve pigs (52.5 +/- 4.9 kg) were studied over a period of 24 hours. In six animals, the intra-abdominal pressure was increased to 30 mm Hg via carbon(More)
The purpose of this study was to investigate whether an intra-abdominal pressure (IAP) of 30 mmHg lasting 24 h in a porcine model will lead to a condition comparable with the abdominal compartment syndrome (ACS) in humans. We examined 12 intubated and anesthetized domestic pigs with a mean body weight of 52.5 +/- 4.9 kg. Using a CO2 pneumoperitoneum, the(More)
BACKGROUND An intra-abdominal pressure (IAP) of 15 mm Hg reduces intestinal organ perfusion in humans and animals, but it is unknown whether this results in organ damage. The purpose of this study was to evaluate if an IAP of 15 mm Hg lasting for 24 h in a porcine model will lead to morphologic impairment of intestinal and adjacent organs. METHODS We(More)
The definitive closure of the abdominal wall, i.e., a closure of the fascial layer and skin may not be favorable in the treatment of numerous surgical conditions, e.g., peritonitis, trauma, or mesenteric ischemia. In these cases, the abdominal wall is temporarily closed, and a laparostomy is created to facilitate re-exploration or to prevent abdominal(More)
Intravesical bladder pressure (IVP) measurement is considered to be the gold standard for the assessment of intra-abdominal pressure (IAP). However, this method is indirect, discontinuous, and potentially infectious and relies on a physiological bladder function. This study evaluated two novel methods for direct, continuous IAP measurement. Experimental(More)
