[Severe hemodynamic instability during the use of isoflurane in a patient with idiopathic scoliosis: case report.].

Background And Objectives: Isoflurane is considered a safe inhalational anesthetic. It has a low level of biotransformation, and low hepatic and renal toxicity. In clinical concentrations, it has minimal negative inotropic effect, causes a small reduction in systemic vascular resistance, and, rarely, can cause cardiac arrhythmias.
