【Objective】 To estimate the application value of washed red blood cells (RBC) in perioperative patients with liver cancer. 【Methods】 86 perioperative patients with liver cancer who met the inclusion/exclusion criteria were divided into observation group (n=42) and control group (n=44). In the observation group, 22 patients were transfused with RBC and 20 with washed RBC. Patients without RBC transfusion worked as the controls. The name of disease, tumor stage, tumor size, Hb before and after blood transfusion, transfusion volume and blood components, adverse reaction to blood transfusion, operation time and blood loss during surgery, systemic infection, tumor recurrence and metastasis, and survival time were recorded. Blood transfusion efficacy, survival time, adverse reaction to blood transfusion, tumor recurrence and metastasis among these groups were compared. 【Results】 Among the non-transfusion group, washed RBC group and RBC group, the Hb(g/L)were 93.9±16.5 vs 80.4±24.5 vs 74.7±26.1, operative time (h) 2.8±0.7 vs 4.3±1.6 vs 3.9±2.0, operative blood loss(mL) 291.0±0.3 vs 388.0±165.8 vs 466.3±198.4 respectively before blood transfusion (all P<0.05). There were no significant differences in the efficacy of blood transfusion and survival time among the three groups (P>0.05). There were significant differences in tumor metastasis (50% vs 43%) and recurrence (50% vs 43.1%) between blood transfusion group and non-blood transfusion group (P<0.05). There was no difference in tumor metastasis (50% vs 48%) and recurrence (50% vs 49%) between the washed RBC group and RBC group (P>0.05). The nosocomial infection rate in washed RBC group (36%) was significantly lower that that in RBC group (88.6%) and non-transfusion group (50%) (P<0.05). 【Conclusion】 Blood transfusion caused by hypoxia may increase tumor metastasis and recurrence in perioperative patients with liver cancer. Transfusion of washed RBC can achieve the curative effect and reduce adverse reactions to blood transfusion, but has no significant impact on the survival time.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
