Evaluation on efficacy and safety of blood-letting tape used in lower extremity varicose vein operation / 重庆医学

ABSTRACT

Objective To investigate the efficacy and safety of exsanguination band used in the lower extremity varicose vein operation.Methods A total of 158 cases of lower extremities varicose veins in this hospital served as the research subjects.All cases underwent the high ligation of great saphenous vein combined with punctate stripping operation.Among them,117 cases intraoperatively used the exsanguination band for blocking the lower limb blood flow (observation group),41 cases did not use the exsanguination band (control group).Then the intraoperative bleeding volume,operation time,pain degree and postoperative complications were observed in the two groups.Results Compared with the control group,the operation time,intraoperative blood loss,hematoma score,prothrombin time (PT) and fibrinogen (FIB) in the observation group were significantly decreased (P＜0.05),while activated partial thrombin time (APTT) and thrombin time (TT) were significantly increased(P＜0.05).The lower limb blood flow occlusion time in the observation group was 45-62 min with an average of (46.68-5.53) min.The sensory score and pain score at postoperative 2 weeks had no statistical difference between the two groups (P＞0.05).No arterial abnormalities and no obvious ischemic injury were found in the injured limbs of 2 groups.Conclusion Applying the exsanguination band for transiently blocking the blood flow can effectively shorten the operation time,reduces the intraoperative bleeding amount and decreases the subcutaneous hematoma formation risk with high safety.
