Abstract:
Haemorheological changes, including blood viscosity (?b) and plasma viscosity (?p) measured on a cone-plate viscometer, erythrocyte aggregation calculated, erytkrocyte deformability (DI) determined by the nuclear pore microfiltration technique and red blood cell shape using scanning electromicroscopy, were observed in patients during anesthesia There acs a significant reduction in ?b (at shear rates range 7. 68- 307. 20 s-l ), ?p and haemotocrit after induction (preintubation ) and 30 min after enflurane in the presence of iv fentanyl, compared with pre-aneathesia, accompanying remarkable increased DI. No changes of erythrocyte shape, however, was found add, nor was the difference of the index between induction period and maintenance of anesthesia. These findings suggest that general anesthesia leads to haemorheological alterations which may improve the microcirculation of the patients.
