Pressure work index maintains reliability for estimating myocardial oxygen consumption during halothane in dogs; leaves open translation to clinical anesthesia.
Does 0.95% end-tidal halothane anesthesia alter the relationship between myocardial oxygen consumption and hemodynamic indices in dogs?
Myocardial oxygen consumption can be accurately estimated during low-dose halothane anesthesia using the pressure work index, which performs better than the systolic pressure rate product.
