ABSTRACT

Introduction: There are reports of decreased brain perfusion pressure related to Intra-abdominal hypertension syndrome. This protocol evaluates the impact of increased abdominal pressure in brain perfusion and oxygenation.
Objectives: To evaluate the effects of increased intra-abdominal Pressure (IAP) on intracranial pressure (ICP), Brain tissue oxygen pressure (PbtO2) and saturation of jugular bulb (SjvO2) in normovolemic porcine model.
Methods: 3 porcine models were tested, in which we induced increase in abdominal pressure at different levels; there were performed measurements of intracranial pressure (ICP), brain tissue Oxygen pressure (PbtO2) and jugular bulb saturation (SjvO2) in each level of Intra-abdominal pressure. Subgroups were analyzed according to the level of intra-abdominal pressure and we made analysis of variance (ANOVA) considering significant a p value ‹ 0.05.
Results: The trend in the increase of ICP and the fall of PbtO2 and SjO2 is constant when Intra-abdominal pressure reaches 25 mmHg (p ‹ 0.5).
Conclusions: In a porcine model with normal brain, ICP increased significantly from 20 mmHg IAP, an opposite behavior occurred with the PbtO2 and SjvO2.
