[A method for understanding halothane-induced changes of cytosolic calcium concentrations in blood platelets].

A method will be presented for monitoring the halothane-induced changes of the cytosolic calcium concentration in blood platelets. Using the fluorescent indicator quin2 it was demonstrated for the first time that halothane causes a temporary increase of the cytosolic free calcium in platelets. The parameter Mean Cytosolic Calcium Concentration describes the halothane-induced changes quantitatively.
