Pressure recording analytical method estimates cardiac output
(HealthDay)—The MostCare pressure recording analytical method (PRAM) is comparable to the Fick method of cardiac output estimation in pediatric patients, according to a study published online Aug. 27 in Pediatric Anesthesia.
José M. Alonso-Iñigo, M.D., Ph.D., from Hospital Clínico Universitario in Valencia, Spain, and colleagues conducted a single-center observational study involving 52 pediatric patients who underwent diagnostic right and left catheterization. Under hemodynamically stable conditions, cardiac index (CI) measurements were obtained with the MostCare-PRAM and Fick methods.
The researchers observed good agreement for CIFick and CIPRAM in the 40 CI measurements (r² = 0.90; P < 0.001), with a mean bias of −0.075 and a percentage error of 17 percent. Patients below 20 kg had similar results (r² = 0.87; P < 0.001), with a mean bias of −0.135 and percentage error of 17 percent.
"In pediatric patients undergoing diagnostic right and left heart catheterization, the MostCare-PRAM was shown to estimate CI with a good level of agreement with the Fick method measurement," the authors write.
