Abstract
INTRODUCTION The arbitrary geriatric age cutoff of 65 may not accurately define older adults at higher risk of mortality following massive transfusion (MT). We sought to redefine a new geriatric age threshold for MT and understand its association with outcomes. MATERIAL AND METHODS The 2013-2018 Trauma Quality Improvement Program database was queried for all adults who received ≥10 units of packed red blood cells (pRBCs) within 24 h of admission. A bootstrap analysis using multiple logistic regression established transfusion futility thresholds (TTs), where additional pRBCs no longer improved mortality for various age cutoffs. The age cutoff at which the TT for those relatively older and relatively younger was statistically significant was used to define the new "geriatric" age for MT. Outcomes were then compared between the newly defined geriatric and nongeriatric patients. RESULTS The difference in TT first became significant when the age cutoff was 63 y. The TT for patients aged ≥63 y (new geriatric, n = 2870) versus <63 y (nongeriatric, n = 17,302) was 34 and 40 units of pRBCs, respectively (P = 0.04). Although geriatric patients had a higher Glasgow coma scale score (9 versus 6, P < 0.01) and lower abbreviated injury score-abdomen (3 versus 4, P < 0.01) than the nongeriatric, they suffered higher overall mortality (62% versus 45%, P < 0.01). A lower percentage of geriatric patients were discharged to home (7% versus 35%, P < 0.01). CONCLUSIONS The new geriatric age for MT is 63 y, with a TT of 34 units. Despite suffering less severe injuries, physiologically "geriatric" patients have worse outcomes following MT.

Abstract
Uncontrollable bleeding is recognized as the leading cause of preventable death among trauma patients. Early transfusion of blood products, especially plasma replacing crystalloid and colloid solutions, has been shown to increase survival of severely injured patients. However, the requirements for cold storage and thawing processes prior to transfusion present significant logistical challenges in prehospital and remote areas, resulting in a considerable delay in receiving thawed or liquid plasma, even in hospitals. In contrast, freeze- or spray-dried plasma, which can be massively produced, stockpiled, and stored at room temperature, is easily carried and can be reconstituted for transfusion in minutes, provides a promising alternative. Drawn from history, this paper provides a review of different forms of dried plasma with a focus on in vitro characterization of hemostatic properties, to assess the effects of the drying process, storage conditions in dry form and after reconstitution, their distinct safety and/or efficacy profiles currently in different phases of development, and to discuss the current expectations of these products in the context of recent preclinical and clinical trials. Future research directions are presented as well.

Abstract
Despite the importance of the hemostatic properties of reconstituted freeze-dried plasma (FDP) for trauma resuscitation, few studies have been conducted to determine its post-reconstitution hemostatic stability. This study aimed to assess the short- (≤24 h) and long-term (≥168 h) hemostatic stabilities of Canadian and German freeze-dried plasma (CFDP and LyoPlas) after reconstitution and storage under different conditions. Post-reconstitution hemostatic profiles were determined using rotational thromboelastometry (ROTEM) and a Stago analyzer, as both are widely used as standard methods for assessing the quality of plasma. When compared to the initial reconstituted CFDP, there were no changes in ROTEM measurements for INTEM maximum clot firmness (MCF), EXTEM clotting time (CT) and MCF, and Stago measurements for prothrombin time (PT), partial thromboplastin time (PTT), D-dimer concentration, plasminogen, and protein C activities after storage at 4 °C for 24 h and room temperature (RT) (22-25 °C) for 4 h. However, an increase in INTEM CT and decreases in fibrinogen concentration, factors V and VIII, and protein S activities were observed after storage at 4 °C for 24 h, while an increase in factor V and decreases in antithrombin and protein S activities were seen after storage at RT for 4 h. Evaluation of the long-term stability of reconstituted LyoPlas showed decreased stability in both global and specific hemostatic profiles with increasing storage temperatures, particularly at 35 °C, where progressive changes in CT and MCF, PT, PTT, fibrinogen concentration, factor V, antithrombin, protein C, and protein S activities were seen even after storage for 4 h. We confirmed the short-term stability of CFDP in global hemostatic properties after reconstitution and storage at RT, consistent with the shelf life of reconstituted LyoPlas. The long-term stability analyses suggest that the post-reconstitution hemostatic stability of FDP products would decrease over time with increasing storage temperature, with a significant loss of hemostatic functions at 35 °C compared to 22 °C or below. Therefore, the shelf life of reconstituted FDP should be recommended according to the storage temperature.

Severe hypocalcemia at admission is associated with increased transfusion requirements: A retrospective study in a level 1 trauma center. Injury 2024; 55:111168. [PMID: 37926665 DOI: 10.1016/j.injury.2023.111168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 09/27/2023] [Accepted: 10/26/2023] [Indexed: 11/07/2023]
Abstract
INTRODUCTION In recent years, hypocalcemia has been added to the "lethal triad" of the trauma patient, thus constituting the "lethal diamond". Nevertheless, its proper role remains debated. The aim of this study is to evaluate the association between severe hypocalcemia at admission and 24 h- transfusion requirements in severe trauma patients in a level 1 trauma center. STUDY DESIGN AND METHODS In a monocentric retrospective observational study from January 2015 to May 2021, 137 traumatized adult patients transfused within 24 h after hospital admission was included in the study. The threshold for severe hypo ionized calcemia was ≤ 0.9 mmol/L. RESULTS 137 patients were included in the study, 23 presented with severe hypo-iCa at admission, 111 moderate hypo-iCa (0.9-1.2 mmol/L) and 3 normal iCa (≥ 1.2 mmol/L). Patients with severe hypo-iCa at admission had higher severity scores (SAPSII 58 IQR [51-70] vs. 45 IQR [32-56]; p = 0.001 and ISS 34 IQR [26-39] vs. 26 IQR [17-34]; p = 0.003). 24 h-transfusion requirements were greater for patients with severe hypo-iCa, regardless of the type of blood products transfused. There was a significant negative correlation between admission iCa and 24 h-transfusion (r = -0.45, p < 0.001). The difference in mortality was not significant between the two groups (24 h mortality: 17 % (4/23) for severe hypo-iCa vs. 8 % (9/114) for non-severe hypo-iCa; p = 0.3). DISCUSSION This study highlights the high prevalence of severe hypocalcemia in trauma patients and its association with increased 24 h- transfusion requirements.

Abstract
BACKGROUND Traumatic rhabdomyolysis (RM) is common and contributes to the development of medical complications, of which acute renal failure is the best described. Some authors have described an association between elevated aminotransferases and RM, suggesting the possibility of associated liver damage. Our study aims to evaluate the relationship between liver function and RM in hemorrhagic trauma patients. METHODS This is a retrospective observational study conducted in a level 1 trauma center analyzing 272 severely injured patients transfused within 24 hours and admitted to intensive care unit (ICU) from January 2015 to June 2021. Patients with significant direct liver injury (abdominal Abbreviated Injury Score [AIS] >3) were excluded. Clinical and laboratory data were reviewed, and groups were stratified according to the presence of intense RM (creatine kinase [CK] >5000 U/L). Liver failure was defined by a prothrombin time (PT)-ratio <50% and an alanine transferase (ALT) >500 U/L simultaneously. Correlation analysis was performed using Pearson's or Spearman's coefficient depending on the distribution after log transformation to evaluate the association between serum CK and biological markers of hepatic function. Risk factors for the development of liver failure were defined with a stepwise logistic regression analysis of all relevant explanatory factors significantly associated with the bivariate analysis. RESULTS RM (CK >1000 U/L) was highly prevalent in the global cohort (58.1%), and 55 (23.2%) patients presented with intense RM. We found a significant positive correlation between RM biomarkers (CK and myoglobin) and liver biomarkers (aspartate transferase [AST], ALT, and bilirubin). Log-CK was positively correlated with log-AST (r = 0.625, P < .001) and log-ALT (r = 0.507, P < .001) and minimally with log-bilirubin (r = 0.262, P < .001). Intensive care unit stays were longer for intense RM patients (7 [4-18] days vs 4 [2-11] days, P < .001). These patients required increased renal replacement therapy use (4.1% vs 20.0%, P < .001) and transfusion requirements. Liver failure was more common (4.6% vs 18.2%, P < .001) for intense RM patients. It was associated with bivariate and multivariable analysis with intense RM (odds ratio [OR], 4.51 [1.11-19.2]; P = .034), need for renal replacement therapy, and Sepsis-Related Organ Failure Assessment Score (SOFA) score on day 1. CONCLUSIONS Our study established the presence of an association between trauma-related RM and classical hepatic biomarkers. Liver failure was associated with the presence of intense RM in bivariate and multivariable analysis. Traumatic RM could have a role in the development of other system failures, specifically at the hepatic level, in addition to the already known and well-described renal failure.
