Open Access Abstract Introduction Correct bedside measurement of intra-abdominal pressure IAP is important. The bladder method is considered as the gold standard for indirect IAP measurement but the instillation volumes reported in the literature vary substantially. The aim of this study was to evaluate the effect of instillation volume on intra-bladder pressure IBP as an estimation for IAP in critically ill patients. Methods In this prospective cohort study in 13 sedated and mechanically ventilated patients we used a revised closed system repeated measurement technique for measurement of IBP. After the system was flushed IBP was measured with 25 ml increments up to 300 ml. The absolute bias for each volume was calculated as IBP at a given volume minus IBP at zero volume. Results In total 30 measurement sets were performed mean per patient . The median IBP at 25 ml was already significantly higher than IBP at zero .
