Background: The clinical pertinence of increased abdominal pressures has gained attention with the high correlation with damage control surgery in trauma. Increasing abdominal compartmental pressures have been associated with an increased rate of multiple organ dysfunction in several studies. This led to the 2004 consensus conference of the World Society on Abdominal Compartment Syndrome (WSACS...

We and others have shown that the loss of fluid and macromolecules from the peritoneal cavity is directly dependent on intraperitoneal hydrostatic pressure (Pip). Measurements of the interstitial pressure gradient in the abdominal wall demonstrated minimal change when Pip was increased from 0 to 8 mmHg. Because flow through tissue is governed by both interstitial pressure gradient and hydraulic...

Few prospective studies have examined associations between major cardiovascular risk factors and occurrence of abdominal aortic aneurysm; findings from cross-sectional studies are inconsistent. This long-term population-based study assessed relationships of major risk factors in middle-age to clinical nonfatal plus fatal abdominal aortic aneurysm in older-age in the Chicago Heart Association De...

Introduction: We aimed to study the effects of different CO2  pressures on expression of P33 gene and apoptosis in liver and spleen cells during CO2 pneumoperitoneum.  Methods: This study was performed on 30 male Sprague-Dawley rats, weighing between 280 and 340 g (procured from Tehran Pasteur Institute’s animal house). They were randomly divided into 3 equal groups. Groups 1 a...

Abdominal compartment syndrome (ACS) occurs when increasing intra abdominal-pressure (IAP) reduces blood flow to abdominal organs. This results in impairment of pulmonary, cardiovascular, renal, hepatic, central nervous system and gastro-intestinal (gi) function, causing multiple organ dysfunction syndrome and death. The significant prognostic value of elevated intra-abdominal pressure has prom...

BACKGROUND To investigate the effect of intra-abdominal volume increment (IAVI) on intra-abdominal hypertension (IAH) in the kidneys. METHODS Eight minipigs were successfully established as IAH models and were randomly divided into two groups: the IAVI group and the sham-operated group. The intravesicular pressure, inferior vena cava pressure and urine volume were measured before shock, 2 h a...

[Purpose] The purpose of this study was to investigate the effective strength levels of abdominal muscle contraction using the bracing contraction method. [Subjects] The experiment was conducted with 31 healthy male (M=15) and female (F=16) adults attending D University in Busan; all participants had less than obesity level BMI (BMI<30). [Methods] Bracing contraction was performed by the subjec...
