ABSTRACT
Objective To analyze the clinical effects of sevoflurane and propofol anesthesia on hemorrheology in elderly patients with colorectal cancer undergoing radical mastectomy.Methods 86 patients with colorectal cancer undergoing radical surgery in our hospital from March 2014 to December 2016 were selected and randomly divided into sevoflurane group and propofol group group with 43 cases in each group.Two groups of elderly patients were anesthetized before, 40 minutes after induction, 80 minutes after induction, 140 minutes after induction and 30 minutes after entering the anesthesia monitoring room 30 minutes to draw the neck 4 mL venous blood.Analysised of two groups of patients with hemorheology ( low cut blood viscosity, blood viscosity in the cut, high shear whole blood viscosity, plasma viscosity, erythrocyte deformation index, erythrocyte aggregation index) index.Results There was no significant difference in the difference of detection indexes between sevoflurane group and propofol group at each time point Comparison of sevoflurane group and propofol group in elderly patients, 40 min, 80 min after induction and 140 min after induction compared with those of pre-anesthesia low-cut whole blood viscosity, middle whole blood viscosity, high shear whole blood viscosity and plasma viscosity, the difference was statistically significant(P<0.05), erythrocyte deformation index and erythrocyte agglutination index were not significantly different between the two groups.The blood viscosity in the propofol group was significantly lower than that in the anesthesia group at 80 minutes after induction and 140 minutes after induction, the difference between the two groups was statistically significant (P<0.05).The whole blood viscosity of the sevoflurane group was significantly lower than that before anesthesia at 140 min, and the difference between the two groups was statistically significant (P<0.05).Conclusion From the point of view of hemorheology, sevoflurane and propofol anesthesia can be used in elderly patients with colorectal cancer radical operation.
