When unpredicted surgical blood loss occurs, it is essential that blood arrive from the blood bank in a timely manner.
To evaluate the turnaround time (TAT) for red blood cells (RBCs) from the blood bank to the operating suite. Cases with delayed TATs were further analyzed to determine potential causes for the delays.
During a 6-month period, intraoperative RBC requests were included among the blood component request lists at a single tertiary care hospital.
A total of 387 RBC-product requests were received from the operating room, of which 220 (56.8%) cases were intraoperative requests. The overall mean (SD) TAT was 19.4 (9.8) minutes. Mean (SD) preparation-to-issuance time (14.9 [7.8] minutes) contributed more to the overall TAT than did mean (SD) request-to-preparation time (4.5 [7.4] minutes). The 31 cases (14.1%) exceeded the internally mandated TAT threshold (> 30 minutes). Prolonged compatibility testing and delayed courier arrival contributed to TAT delay.
TAT standards for issuing RBCs from the blood bank to the operating suite should be established and carefully monitored for quality improvement of transfusion services.
当发生意外手术失血时，至关重要的是血库的血液要及时送达。
评估红细胞从血库到手术室的周转时间（TAT）。对周转时间延迟的病例进行进一步分析，以确定延迟的潜在原因。
在6个月期间，一家三级护理医院的血液成分申请清单中纳入了术中红细胞申请。
手术室共收到387份红细胞制品申请，其中220例（56.8%）为术中申请。总体平均（标准差）周转时间为19.4（9.8）分钟。平均（标准差）准备到发放时间（14.9 [7.8]分钟）对总体周转时间的贡献大于平均（标准差）申请到准备时间（4.5 [7.4]分钟）。31例（14.1%）超过了内部规定的周转时间阈值（>30分钟）。相容性检测时间延长和快递员到达延迟导致了周转时间延迟。
应制定血库向手术室发放红细胞的周转时间标准，并进行仔细监测，以改善输血服务质量。
