摘　　要：目的通过观察传统导管转接方法和改良导管转接方法在去白细胞血液导管转接制备中的应用,探讨改良导管转接方法在降低因热合口渗漏导致去白细胞血液报废方面的效果。方法血液滤除白细胞后,去白细胞血液产品袋管路由原来直接热合再转接血袋导管改良为先热合两段,然后在远端热合口处转接血袋导管。对2种方法在去白细胞血液制备导管转接环节因热合渗漏导致的去白细胞血液报废率进行统计分析。结果经过对工作人员的反复培训,在使用同型号热合机的情况下,改良导管转接方法因热合渗漏导致的血液报废率为0(0/33 595),显著低于传统导管转接方法因热合渗漏导致的血液报废率0.11%(36/32 873,P<0.001)。结论改良导管转接方法显著降低了因热合渗漏导致的血液报废,节约了宝贵的血液资源,但该方法仍存在对接热合口渗漏的风险,工作人员应做好职业暴露预防措施。Objective To observe the application of the traditional and modified catheter transfer method in leukocyte-depleted blood preparation and the effect of modified method on reducing the blood discard rate due to hot joint leakage. Methods After leucocyte filtration, the traditional method is to seal the product bag catheter directly and then connect the whole blood catheter, while the modified method is to seal the two sections on the product bag catheter and then connect the whole blood catheter at the distal seal. The blood discard rates of the two methods due to the hot joint leakage in the catheter connection of leukocyte reduction were analyzed. Results After repeated training for the staff, using the same type of equipment, the blood discard rate due to heat sealing leakage by modified method was 0(0/33 595), significantly lower than that by traditional method(0.11%, 36/32 873, P<0.001). Conclusion The modified method can significantly reduce the discard rate of blood due to seal leakage and save valuable blood resources. However, there is still a risk of seal leakage, and staff should take preventive measures against occupational exposure.
