| Abstract |
Blood and urinary inorganic fluoride ion concentration was determined in six healthy volunteers after inhalation of 2% sevoflurane for one hour. The serum inorganic fluoride ion concentration increased 30 min after discontinuation of inhalation to 14.8 ± 3.0 μmol/liter, which was about 10 times higher than the level before inhalation. The serum elimination constant of inorganic fluoride was calculated to be 0.000467 and the half-life was 1,487 min.
The urinary excretion rate of inorganic fluoride ion was the highest ( 452 nmol/min) after 12-24 hr. The urinary excretion rate constant of inorganic fluoride was calculated to be 0.000268 and the half-life was 2,583 min. The distribution volume of inorganic fluoride excreted in the urine was calculated to be 127 liters. This value showed that fluoride ion produced in the cell cannot readily pass through the cell membrane due to its polarity, resulting in a delay of the maximum excretion rate of inorganic fluoride until the first or second day after inhalation of the anesthetic. |
