This study evaluated the ability of two Doppler ultrasound-derived parameters, the carotid corrected flow time (FTc) and respirophasic variation in carotid artery blood flow peak velocity (ΔVpeak), to predict fluid responsiveness in spontaneously breathing patients. ⋯ NCT 02843477.

Effective pulmonary blood flow (COEPBF) has recently been validated as a technique for determining cardiac output (CO) in animals of varying sizes. The primary aim of our study was to investigate this new technique in paediatric surgical patients, compared with suprasternal two-dimensional Doppler (COSSD). ⋯ Under controlled experimental conditions, COEPBF is associated with excellent agreement and good trending ability when compared with the gold standard COTS. In the paediatric clinical setting, COEPBF performs well; by contrast, COSSD, an operator- and anatomy-dependent technology, appears less reliable than COEPBF.
