Objective. To evaluate the effect of massive transfusion protocol on coagulation function in elderly patients with multiple injuries. Methods. In this retrospective cohort study, clinical data were collected from a total of 94 elderly patients with multiple injuries, including 44 cases who received routine transfusion protocol (control group) and 50 cases who concurrently received massive transfusion protocol in our hospital (research group). The changes in platelet parameters, coagulation function, and organ dysfunction scores at admission and 24 h after transfusion were compared between the two groups. The 24-hour plasma and red blood cell transfusion volume, length of stay, complications, and mortality of the two groups were analyzed statistically. Results. Twenty-four hours after blood transfusion, the hematocrit, platelets, and hemoglobin in the research group were higher than those in the control group, while the activated partial thromboplastin time, prothrombin time, thrombin time, fibrinogen, and scores of Marshall scoring system and Sequential Organ Failure Assessment were lower than those in the control group ( P < 0.01 ). The 24-hour plasma transfusion volume was higher, and the length of intensive care unit (ICU) stay and total length of stay were lower in the research group compared with the control group ( P < 0.01 ). No significant difference was found in the mortality rate between the research group and the control group (10.00% vs. 13.64%, P > 0.05 ). The incidence of complications in the research group was lower than that in the control group (12.00% vs. 31.82%, P < 0.05 ). Conclusion. Massive transfusion protocol for elderly patients with multiple injuries can improve their coagulation function and platelet parameters, alleviate organ dysfunction, shorten length of ICU stay, and decrease the incidence of complications, which is conducive to improving the prognosis of patients.

PurposeTo compare the effect of allogeneic transfusion and acute normovolemic hemodilution (ANH) autologous transfusion in patients undergoing cesarean section.MethodsPatients who underwent cesarean section and received blood transfusion therapy from February 2019 to July 2021 in our hospital were observed and divided into the allogeneic group (n = 55) who received allogeneic transfusion therapy and the autologous group (n = 55) who received ANH autologous transfusion therapy according to the mode of transfusion. Observations included vital signs [heart rate (HR), mean arterial pressure (MAP), stroke volume variation (SVV)], blood routine [red blood cells (RBC), platelets (PLT), hematocrit (HCT), hemoglobin (Hb)], T-cell subsets (CD4+, CD8+, CD4+/CD8+), immunoglobulins (IgA, IgM, IgG), inflammatory factors [C-reactive protein (CRP), tumor necrosis factor (TNF)-α, interleukin (IL)-6], and adverse effects were counted in both groups.ResultsThere was no statistical significance in the intra-group and inter-group comparisons of HR, MAP, and SVV between the two groups before transfusion and transfusion for 10 min (P &gt; 0.05). 5d after operation, the RBC, PLT, HCT, and Hb of the allogeneic group were lower than those before operation, and the autologous group was higher than that of the allogeneic group (P &lt; 0.05). 5d after operation, the CRP, TNF-α, and IL-6 of the allogeneic group were higher than those before operation, and the autologous group was lower than that of the allogeneic group (P &lt; 0.05). 5d after operation, the CD4+, CD4+/CD8+ of the allogeneic group were lower than before operation, and the CD8+ was higher than before operation. The CD4+ and CD4+/CD8+ of the autologous group were higher than that of the allogeneic group, and CD8+ was lower than that of the allogeneic group (P &lt; 0.05). 5d after operation, the IgA, IgG, and IgM of the allogeneic group were lower than those before operation, and the autologous group was higher than that of the allogeneic group (P &lt; 0.05). During blood transfusion, there was no significant difference in the adverse reaction rate between the two groups (P &gt; 0.05).ConclusionBoth allogeneic transfusion and ANH autologous transfusion have little effect on the vital signs of patients undergoing cesarean section, but ANH autologous transfusion is more helpful to the stability of blood routine, T-cell subsets, immunoglobulin, and inflammation levels after surgery, which is a safe and effective way of blood transfusion.
