Massive blood transfusion following older adult trauma: The effect of blood ratios on mortality.

Massive blood transfusion (MBT) following older adult trauma poses unique challenges. Despite extensive evidence on optimal resuscitative strategies in the younger adult patients, there is limited res... We used the Trauma Quality Improvement Program (TQIP) database from 2013 to 2017 to identify all patients over 65 years old who received a MBT. We stratified our population into six fresh-frozen plasm... A total of 3134 patients met our inclusion criteria (median age 73 ± 7.6 years, 65% male). On risk-adjusted multivariable analysis, 1:1 FFP:pRBC ratio was independently associated with lowest 24-h mor... Compared to all other ratios, the 1:1 FFP:pRBC ratio had the lowest 24-h and 30-day mortality following older adult trauma consistent with findings in the younger adult population....

Suspected adverse reactions reported for blood, blood components, and blood products in VigiBase.

Since being designated as medicines by World Health Organization (WHO), blood components are subject to pharmacovigilance reporting. Using VigiBase, the WHO global database of individual case safety r... ICSRs involving blood products as the suspected medicine in VigiBase between 1968 and 2021 were extracted. MedDRA preferred terms and the International Society of Blood Transfusion haemovigilance defi... A total of 111,033 ICSRs containing 577,577 suspected adverse reactions with 6152 MedDRA preferred terms were reported for 34 blood products. There were 12,153 (10.9%) reports for blood components, 98... VigiBase already has a large number of reports on blood products. When compared to other existing haemovigilance databases, our study found reports from a broader range of countries and reporters. Thi...

In vitro comparison of CPD whole blood with conventional blood components.

Resuscitation of severely injured trauma patients is commonly performed using red blood cells in additive solution supplemented with plasma and platelet concentrates. There is an increasing interest i... Expired units of CPD-LTOWB were studied on Day 22 and expired units of thawed plasma on Day 6 and Day 7. LTOWB was assessed for hemoglobin content, clotting factor levels and platelet numbers and func... LTOWB contained slightly more hemoglobin than the AS-RBCs (Medians, 66 v 59 G), and the plasma content of fibrinogen was similar. Other clotting factors were reduced by approximately 15% except for FV... LTOWB contains higher hemoglobin and adequate clotting factors, and residual platelet function is demonstrated indicating that this product would be expected to be at least equivalent to a single unit...

Training of medical students in the use of emergency whole blood collection and transfusion in the framework of a civilian walking blood.

The overall aim of the program is to improve the av... The voluntary training program provides the knowledge needed to practice emergency whole blood transfusions and understand the system for emergency whole blood collection in the framework of a civilia... 128 of 178 students participated in the practical training. 88 of 128 (69%) responded to the survey. 82 (93%) performed blood typing, 71 (81%) performed donor interviews, 61 (69%) partially performed ... Structured theoretical and practical training in emergency whole blood collection and emergency transfusion is feasible and of interest to medical students. A multidisciplinary approach to student tra...

Association of red blood cells and plasma transfusion versus red blood cell transfusion only with survival for treatment of major traumatic hemorrhage in prehospital setting in England: a multicenter study.

In-hospital acute resuscitation in trauma has evolved toward early and balanced transfusion resuscitation with red blood cells (RBC) and plasma being transfused in equal ratios. Being able to deliver ... To compare prehospital transfusion of combined RCP versus RBC alone or RBC and plasma separately (RBC + P) on mortality in trauma bleeding patients.... Data were collected prospectively on patients who received prehospital transfusion (RBC + thawed plasma/Lyoplas or RCP) for traumatic hemorrhage from six prehospital services in England (2018-2020). R... Out of 970 recruited patients, 909 fulfilled the study criteria (RBC + P = 391, RCP = 295, RBC = 223). RBC + P patients were older (mean age 42 vs 35 years for RCP and RBC), and 80% had a blunt injury... Prehospital plasma transfusion for penetrating injury was associated with lower odds of death at 24-h compared to RBC alone. Large trials are needed to confirm these findings....
