目的:探讨研究预先配血模式在择期手术交叉配血中的应用。方法:将择期手术输血按传统配血和预先配血2种方式进行,分别统计检测周转时间(TAT),分析TAT延长及手术室不满意的原因,以进一步缩短手术用血等候时间,提高手术室对输血科交叉配血TAT的满意度。结果:标准检测阶段是影响TAT的主要因素,压缩该段TAT是很困难的。研究中传统配血模式的满意度是88%,预先配血模式的满意度是97%,差异有统计学意义(P<0.05)。结论:交叉配血是输血流程中最难提高的一个TAT节点,输血科可以运用预先配血模式解决该问题,提高TAT,缩短手术用血等待时间。 Objective: To explore the application of pre-distribution pattern in the cross-matching blood of elective surgery. Methods: The blood transfusion of elective surgery was performed in two ways: traditional blood distribution and pre-dosing. Statistical analysis of TAT was carried out to analyze the reasons for the prolongation of TAT and the unsatisfactory operation room, so as to further shorten the waiting time for surgical blood and improve the operation Satisfaction with blood TAT in blood transfusion department. Results: The standard test phase is the main factor affecting TAT. It is very difficult to compress this section of TAT. In the study, the satisfaction rate of traditional blood distribution model was 88%, while that of pre-distribution model was 97%. The difference was statistically significant (P <0.05). Conclusion: Cross-matching blood is the most difficult TAT node in blood transfusion process. Blood transfusion department can use pre-dosing mode to solve this problem, increase TAT and shorten waiting time for blood transfusion.
