Intravascular volume depletion in a 24-hour porcine model of intra-abdominal hypertension.

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.

Evaluation of two novel methods for the direct and continuous measurement of the intra-abdominal pressure in a porcine model.

Objective: 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.

A porcine model of the abdominal compartment syndrome.

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.
