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.

Esophageal cancer is the most common malignant tumor of the digestive tract in China. At present, surgical resection is the main method to cure esophageal cancer. With the population and implementation of the enhanced recovery after surgery, perioperative physical therapy plays a more and more important role. This review discussed the necessity of preoperative cardiopulmonary function assessment in patients with esophageal cancer, the effects of preoperative respiratory training and aerobic exercise on optimizing physical fitness and reducing postoperative complications, and the content of early postoperative physical therapy. Preoperative cardiopulmonary function of esophageal cancer patients is not strongly related with the outcome, which may be related to the complexity of esophageal cancer surgery and the high incidence of postoperative complications. Preoperative inspiratory muscle exercise can improve the pulmonary function of patients to some extent, but still lack of large sample size research. Preoperative aerobic exercise for esophageal cancer can improve the patient's physical reserve and should be valued. Postoperative physiotherapy priorities includes pain management, chest physical therapy and early mobilization. Exercise prescriptions such as intensity and time for early mobilization are yet to be further studied.
