“BACKGROUND: Halothane, isoflurane, and sevoflurane exert negative inotropic side effects, generally mediated via a reduced availability of intracellular calcium.”
“The Ca2+ paradox was significantly suppressed by sevoflurane administered for 3 min before and during Ca2+ repletion (Post) or during Ca2+ depletion and repletion (Postlong), and Postlong was more beneficial than Post application.”
“In contrast, sevoflurane initially inhibited frequency of Ca2+ release (to 10% of control), whereas its removal induced a burst of spontaneous Ca2+ release.”
