Sevoflurane was submitted to Phase II studies in patients following Phase I studies. Sevoflurane, 2% inspired during maintenance, was administered with 50% N2O in oxygen to produce surgical anesthesia in 9 orthopedic patients of ASA Physical Status I. Under controlled ventilation, endotracheal concentration of sevoflurane was recorded. The blood concentration of sevoflurane was measured during and after the inhalation. Serum, urinary inorganic fluoride, and glucuronide of hexafluoroisopropanol were analysed with ion chromatographic analyzer.
The patient inhaled sevoflurane for 3.5 ± 1.6 hr. All the patients were anesthetized and operated uneventfully. Postoperative laboratory findings showed no unexplainable abnormality. The end expiratory concentration of sevoflurane reached a plateau in 4.0 ± 0.8 min and fell rapidly after discontinuation of sevoflurane. Blood concentration of sevoflurane was about 500 μM during inhalation. It decreased promptly after termination of sevoflurane and was not correlated with anesthetic time. The time for verbal response after discontinuation was 11.8 ± 4.2 min. The serum concentration of inorganic fluoride increased after inhalation and reached a plateau (13.7 ± 8.2 μM) in 120 min. The level lasted for 120 min after anesthesia and fell by half at 12 hr after anesthesia. Urinary fluoride concentration varied from 20 to 3,000 μM during the first 12 hr urine, and showed its maximum in the first postoperative 12 or 24 hr urine.
The findings that sevoflurane with nitrous oxide and oxygen produced surgical anesthesia without any sequelae and that the serum fluoride level did not exceed the nephrotoxic level warrent the further clinical evaluation in a wider range of subjects.
