Objective To evaluate the effect of a new type of narrow sterile hemostatic ring on blood loss during upper limb lymphedema aspiration. Methods 150 patients with upper limb lymphedema were treated with four different types of aspiration. In the first group，the operation was performed under the condition of hemostasis ring and autotransfusion. In the second group，the operation was performed without the use of hemostasis ring and autotransfusion. In the third group，the operation was performed with the hemostatic ring and without autotransfusion. In the fourth group，the operation was performed without the use of hemostasis ring and autotransfusion. The blood loss，surgical effect and postoperative complications of patients in different groups were compared. Results In the hemostatic ring aspiration group（Group 1 and Group 3），the hemoglobin decrease was（16.90 ± 8.45）g/L，and the blood loss was（328.43 ± 171.54）mL. In the conventional aspiration group（Group 2 and Group 4），the hemoglobin decrease was（20.95 ± 9.55）g/L，and the blood loss was（442.42 ± 172.08）mL. The hemoglobin decrease and the blood loss index in the hemostatic ring aspiration group and the conventional aspiration group were statistically significant（P < 0.05），Using a narrow sterile hemostatic collar can significantly reduce blood loss. The hemoglobin decrease（18.42 ± 8.75）g/L and blood loss（381.00 ± 194.02）mL were observed in the autologous blood group （Group 1 and Group 4），while the hemoglobin decrease（20.15 ± 9.64）g/L and blood loss（415.00 ± 171.96）mL were observed in the non autologous blood group（Group 2 and Group 3）. There was no statistically significant difference in the hemoglobin decrease and blood loss indicators between the two groups（P > 0.05），The use of autologous blood transfusion has no significant impact on blood loss and postoperative hemoglobin decline in patients. The surgical time for group 1 was（97.82 ± 24.90）min，for group 2 was（97.74 ± 22.48 ）min，for group 3 was （88.83 ± 21.06）min，and for group 4 was（104.82 ± 16.25）min，with no statistically significant difference（P > 0.05）. The use of narrow sterile hemostatic ring and autologous blood transfusion did not increase the surgical time. The amount of fat sucked out in group 1 was（1 380.77 ± 482.81）mL，the amount of fat sucked out in group 2 was （1 122.95 ± 382.43）mL，the amount of fat sucked out in group 3 was（1 275.00 ± 478.87）mL，and the amount of fat sucked out in group 4 was（1 272.73 ± 610.07）mL，with a statistically significant difference（P < 0.05）. Using a narrow sterile hemostatic collar and autologous blood transfusion can significantly increase the amount of fat tissue sucked out. After surgery，patients in different groups experienced different degrees of limb sensory abnor⁃ malities and limited range of motion，with no statistically significant difference（P > 0.05）. Conclusions The use of narrow sterile hemostatic ring for upper limb lymphedema aspiration can effectively reduce the amount of bleeding.
