Predicting Fluid Responsiveness During Infrarenal Aortic Cross-Clamping in Pigs.
Infrarenal aortic cross-clamping (ACC) induces hemodynamic disturbances that may affect respiratory-induced variations in stroke volume and, therefore, affect the ability of dynamic parameters such as pulse-pressure variation (PPV) to predict fluid responsiveness. Since this issue has not been investigated yet to authors' knowledge, the hypothesis was tested that ACC may change PPV and impair its ability to predict fluid responsiveness. ⋯ ACC induced a significant increase in PPV and reduced its ability to predict fluid responsiveness.
