Interventions/Control_1

Group 1 is defined by UFH 0 units per day. Pre-observation period is defined as from the first outpatient consultation to completion of surgery. The onset of the study is defined to be the time of replantation of the digit with anastomosis of the vein. The follow-up period is approximately one month after surgery. The minimum and the maximum periods are defined as 2 weeks and 2 months, respectively, for all examination items. The observation period is defined in the same manner. Continuous intravenous infusion of prostaglandin preparation for 7 days at the rate of 120yg/day, postoperatively. Each item is evaluated three times by blood test at 6 hours, 3 days, and 7 days, postoperatively. Additional treatments are promptly planned and conducted when considered necessary. The best conceivable prevention, diagnosis, and treatment are to be offered, considering the results of this study. Hemoglobin is controlled to be 10 mg/dL or higher, postoperatively. UFH administration is suspended only when anemia is difficult to control, although UFH administration is to be continued for cases where blood transfusion is effective in improving the condition. When presence of infection is suspected, culture of the wound is to be immediately submitted, and appropriate antibiotics (first generation cephem) are administered, considering the epidermal normal bacteria flora as pathogenic bacteria (causative organisms).

Interventions/Control_2

Group 2 is defined by UFH 10,000 units per day. Continuous intravenous drip infusion of UFH is started from soon after surgery. The dose period is 7 days. Each item is evaluated three times by blood test at 6 hours, 3 days, and 7 days, postoperatively.Continuous intravenous infusion of prostaglandin preparation for 7 days at the rate of 120yg/day, postoperatively.

Interventions/Control_3

Group 3 is defined by UFH 15,000 units per day. Continuous intravenous drip infusion of UFH is started from soon after surgery. The dose period is 7 days. Each item is evaluated three times by blood test at 6 hours, 3 days, and 7 days, postoperatively. In Group 3, dosage of UFH is adjusted, and APTT is controlled to be 1.5 to 2.5-fold that of preoperative levels. Continuous intravenous infusion of prostaglandin preparation for 7 days at the rate of 120yg/day, postoperatively.
