Does respiratory variation in aortic blood flow peak velocity predict fluid responsiveness in children?
Respiratory variation in aortic blood flow peak velocity is the only reliable predictor of fluid responsiveness in children, while static and arterial blood pressure-based dynamic variables are ineffective.
Respiratory variation in aortic blood flow peak velocity was the only variable shown to predict fluid responsiveness in children. Static variables did not predict fluid responsiveness in children, which was consistent with evidence in adults. Dynamic variables based on arterial blood pressure did not predict fluid responsiveness in children, but the evidence for dynamic variables based on plethysmography was inconclusive.
