The purpose of present study was to compare the effects of desflurane and sevoflurane on blood viscosity in three different shear rates and plasma viscosity. Forty male patients, ASAI-II, undergone tympanoplasty were included in this study. Patients were randomly categorized as anaesthetized either with sevoflurane or desflurane. Anaesthesia was maintained with inspiratory concentrations of sevoflurane 1-1.5 MAC or desflurane. The samples were taken for hemorheological and biochemical examinations before induction of anaesthesia (initial time) and at 60th and 120th min of the operation. Blood viscosities were measured by rotational viscometer. Plasma viscosity was measured by capillary viscometer. Patients receiving desflurane showed steady decrease at 23 1/sec shear rate at 60th and 120th min and in blood viscosity at 115 1/sec shear rate in 120th min. Statistically significant decrease in the level of plasma viscosity was observed in the patient group anesthetized with desflurane, between initial time vs 60th min (p<0.01), initial time vs 120th min. (p<0.01). Desflurane produced stable effects on the blood circulation. The differences in the blood viscosity should not be overlooked.
