Comparative Study
Serum inorganic fluoride and renal function in dogs after methoxyflurane anesthesia, tetracycline treatment, and surgical manipulation.
Effects of 2 hours of methoxyflurane-induced anesthesia in 25 dogs were determined by serum inorganic fluoride, serum urea nitrogen, serum creatinine, water intake, urine excretion, and urine specific gravity measurements; arterial concentrations of the anesthetic were also determined. The dogs were allotted to 5 groups (PTM, CTM, PTML, CTML, ML) of 5 dogs in each group and were anesthetized (M, in group designations) for 2 hours. The dogs were injected with chemically pure tetracycline or commercial tetracycline (PT and CT, in group designations) before, on the day of, and after anesthesia. ⋯ Water intake reached peak at 48 hours after anesthesia. Arterial concentrations of methoxyflurane determined at 60 and 120 minutes of anesthesia indicated no difference (P greater than 0.05) among groups. Neither clinical nor laboratory signs of severe kidney dysfunction were detected in any of the experimental dogs during a 5-day observation period after anesthesia.
