Fig. 8. Age-related differences in the effect of volatile anesthetics on Na⁺–Ca²⁺exchange (NCX)-mediated Ca²⁺influx. Both anesthetics inhibited Ca²⁺influx to a greater extent in neonatal myocytes (A ) compared with adults (B ). *Difference from control; §age-related differences; †difference between 1 and 2 minimum alveolar concentration (MAC); ‡difference between halothane and sevoflurane. Values are mean ± SD.
