Objective To explore the clinical effect and influence of hemocoagulase on bleeding control and coagulation function in neu -rosurgery .Methods A total of 300 patients with surgical treatment in our hospital from June 2013 to June 2014 were randomly divided into control group (n=150) and observation group (n=150).The patients in control group were treated with physiological saline 10 mL topical spraying,while the patients in observation group were treated with physiological saline 10 mL plus hemocoagulase 4U topical spraying.The clinical effect and coagulation index were compared between the two groups .Results The bleeding volume of the observation group was sig-nificantly lower than that of the control group (P<0.01).No significant difference was found in the coagulation index of the two groups (P>0.05).Conclusion Hemocoagulase treatment during the operation can reduce the volume of bleeding and transfusion of blood ,and do not affect the coagulation function in the patients .
