OBJECTIVE: Compare invasive blood pressure (IBP) and noninvasive blood pressure (NIBP) measurement methods in the neonatal intensive care unit (NICU) across various gestational age and postmenstrual age (PMA), and determine the effect of gestational age and PMA on accuracy of NIBP measurements. STUDY DESIGN: Retrospective chart review of paired mean IBP and NIBP measurements from infants admitted to a single NICU from January 2008 through December 2010. Infants with congenital anomalies or receiving therapeutic hypothermia were excluded...

BACKGROUND: Gastric residual volume (GRV) can be measured in a variety of ways in critically ill patients, most often, the nasogastric tube is disconnected and the GRV is aspirated via a 60 mL syringe. Bladder pressure (IBP) measurement is the gold standard for intra-abdominal pressure (IAP) estimation. This study will look at the validation of a novel method combining measurement of GRV and estimation of IAP via intra-gastric pressure (IGP). METHODS: In total 135 paired IAP and 146 paired GRV measurements were performed in 37 mechanically ventilated ICU patients...

In mechanically ventilated patients, Pulse Pressure Variation (PPV) has been shown to be a useful parameter to guide fluid management. We evaluated a real-time automated PPV-algorithm by comparing it to manually calculated PPV-values. In 10 critically ill patients, blood pressure was measured invasively (IBP) and non-invasively (CNAP(®) Monitor, CNSystems Medizintechnik, Austria). PPV was determined manually and compared to automated PPV values: PPVmanIBP vs. PPVautoIBP was -0.19 ± 1.65% (mean bias ± standard deviation), PPVmanCNAP vs...

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...
