ABSTRACT
Objective To investigate the hemostatic effect and influence on coagulation function of hemecongulase during neurosurgical operation.Methods Sixty patients with neurosurgical trauma at American statistical association(ASA) Ⅰ-Ⅱ were randomly divided into hemocoagnlase treatment group (n =30) and control group(n =30).Both two group were injected Baquting 2U at the day before the operation,30 min before the operation,every two day after the operation and end up 3 d.Treatment group were pedormed with Baqyting 4 U + physiological saline 10 ml topical spraying.The intelligibility of operating region,the volume of intraoperative,the volume of bleeding during the operation,transfusion of blood,postoperative drainage,and drainage tube exelcymosis time were recorded in all the patients.Prothrombin time (PT),activated partial thromboplastin time (APTT),fibrinogen level(FIB),fibrinogen degradation product(FDP) and the two D-dimer and platelet count(PLT) before and after the surgery were also determined.All the patients were postoperatively followed up.Results The intelligibility of operating region was 70.0％ (21/30) in the hemocoagnlase treatment group,higher than that in control group (0％,P ＜0.05).The volume of bleeding during the operation in the hemecoagulase treatment group was (680.00 ± 95.22) ml,significantly fewer than that in the control group((790.00 ±47.00) ml,P =0.034).PLT significantly decreased after the surgery in both of the groups compare to that in preoperation (P ＜ 0.05 or P ＜ 0.01) and no significant difference was seen between two groups (P ＞ 0.05).No severe adverse events were found in both groups.Conclusion Hemocoagulase treatment during the operation can improve the intelligibility of operating region,reduce the volume of bleeding and transfusion of blood,and do not affect the coagulation function in the patients.Therefore,hemocoagulase is a safe and effective hemostatic and through local application during the operation it can improve curative effect.
