Effectiveness of the Pressure Recording Analytical Method in Predicting Fluid Responsiveness in Pediatric Critical Care Patients

The Pressure Recording Analytical Method, invasive hemodynamic monitoring, is an uncalibrated pulse contour analysis, installed in the Mostcare® system that allows a continuous estimation of the stroke volume and thus the cardiac output, by the relationship between the area under the curve of the systolic portion of the arterial blood pressure curve and the dynamic impedance of the cardiovascular system. The objectives of the study are to determine if the parameters measured by Mostcare® make it possible to predict the response to volume expansion in pediatric surgical critical care patients, sedated, intubated and ventilated, by comparing the changes in stroke volume, induced by a volume expansion, measured by trans-thoracic echocardiography.
