Desmopressin Is A Transfusion Sparing Option To Reverse Platelet Dysfunction In Patients With Severe Traumatic Brain Injury Background Platelet dysfunction (PD) is an independent predictor of mortality in patients with severe traumatic brain injury (sTBI). Platelet transfusions have been shown to be an effective treatment strategy to reverse platelet inhibition. Their use is contingent on availability and may be associated with increased cost and transfusion related complications making desmopressin (DDAVP) an attractive. We hypothesized that DDAVP would correct PD similarly to platelet transfusions in patients with sTBI. Methods This retrospective study evaluated all blunt trauma patients admitted to an urban, level one trauma center from July 2015 to October 2016 with sTBI (defined as Head AIS ≥ 3) and PD (defined as adenosine diphosphate [ADP] inhibition ≥60% on thromboelastography [TEG]) and subsequently received treatment. Per our institutional practice patients with sTBI and PD are transfused one unit of apheresis platelets to reverse inhibition. During a platelet shortage, we interchanged DDAVP for the initial treatment. Patients were classified as receiving DDAVP or platelet transfusion (PLT) based on the initial treatment. Results A total of 57 patients were included (DDAVP n=23; PLT n=34). Patients who received DDAVP were more severely injured (ISS: 29 vs. 23, p=0.045) but there was no difference in Head AIS (4 vs. 4, p=0.16). There was no difference between the two groups in admission platelet count (244 ± 68 ×103/uL vs. 265 ± 66 ×103/uL, p =0.24), or other coagulation parameters such at PT, PTT or INR. Prior to treatment both groups had similar ADP inhibition as measured by TEG (ADP 86% vs. 89%, p=0.34). After treatment both the DDAVP and PLT groups had similar correction of platelet ADP inhibition (p=0.28). Conclusion In patients with severe TBI and PD, DDAVP may be an alternative to platelet transfusions to correct PD. LEVEL OF EVIDENCE IV, therapeutic Corresponding Author: Elisa J.

Is all plasma created equal? A pilot study of the effect of interdonor variability BACKGROUND Clinical benefits of plasma as an adjunct for treatment of hemorrhagic shock (HS) have been well established. However, its use is not without risk. Little is understood regarding the clinical implications of plasma variability. We hypothesized there to be interdonor variability in plasma that would impact endothelial and organ function post injury. METHODS Pulmonary endothelial cells (EC) were incubated with plasma from 24 random donors and transendothelial electrical resistance (TEER) was measured. Plasma units with a more or less protective effect on reducing EC permeability were selected for testing in vivo. Syndecan-1 and cytokines were measured. Mice underwent laparotomy then HS followed by resuscitation with the selected plasma units and were compared to mice receiving no resuscitation and shams. Lung tissue was sectioned and stained for myeloperoxidase, pulmonary syndecan-1 and scored for lung histopathologic injury. RESULTS Plasma from 24 donors revealed variability in the reversal of EC monolayer hyperpermeability; TEER for the more protective plasma was significantly higher than for the less protective plasma (0.801±0.022 vs. 0.744±0.035; p=.002). Syndecan-1 was also markedly increased in the less protective compared to the more protective plasma (38427±1257 vs. 231±172pg/mL, p<.001), while cytokines varied. In vivo, the more protective plasma mitigated lung histopathologic injury compared to the less protective plasma (1.56±0.27 vs. 2.33±0.47, respectively, p=.005). Similarly, myeloperoxidase was significantly reduced in the more protective compared to the less protective plasma group (2.590±0.559 vs. 6.045±1.885; p=0.02). Lastly, pulmonary syndecan-1 immunostaining was significantly increased in the more protective compared to the less protective plasma group (20.909±8.202 vs. 9.325±3.412; p=0.018). CONCLUSIONS These data demonstrate significant interdonor variability in plasma that can adversely influence the protective effects of plasma-based resuscitation on HS-induced lung injury. This may have important implications for patient safety and clinical outcomes. Study type: Basic science Level of Evidence not applicable The authors have no conflicts of interest.

DEFINING THE SURGICAL CRITICAL CARE RESEARCH AGENDA: RESULTS OF A GAPS ANALYSIS FROM THE CRITICAL CARE COMMITTEE OF THE AMERICAN ASSOCIATION FOR THE SURGERY OF TRAUMA BACKGROUND There has been an unprecedented increase in critical care research recently and there is a need for an organized and systematic approach to surgical critical care research planning. The purpose of this paper was to establish a surgical critical care research agenda via a systematic review of the literature and needs assessment. METHODS A systematic review of the literature was performed to identify high-impact critical care articles since 1999 on the basis of citation data. Using a standardized data abstraction tool, surgical representation in the literature was analyzed. A needs assessment was performed using a modified Delphi approach in three rounds to obtain consensus among members of the Critical Care Committee of the American Association for the Surgery of Trauma (n=30) regarding research priorities in surgical critical care. RESULTS Of 1,019 articles screened, 645 underwent full-text review, and 276 papers were included in the final analysis. Surgical patients were identified in 177 studies (64.1%), whereas trauma patients were identified in 82 (31.7%). Key categories identified during the first round of the Delphi included end of life care, traumatic brain injury (TBI), delirium, post-ICU syndrome, hemodynamic monitoring, and volume/fluid balance. During the second and third rounds, 10 topics were classified as high priority. The three highest ranked topics were: addressing goals of care in the acute care setting (4.44 ± 0.70); improving prognostic indicators in patients with severe TBI (4.38 ± 0.85); and interventions to mitigate the post-ICU syndrome (4.22 ± 0.65). There was a strong positive correlation in ratings (Rs value = 0.90, p = 0.001) between rounds 2 and 3. CONCLUSIONS The results of this study highlight the recent surgical critical care research literature and may serve as a platform for future research endeavors in surgical critical care.

Rotational Thromboelastometry (ROTEM) Predicts Transfusion and Disability in Pediatric Trauma BACKGROUND Trauma-induced coagulopathy seen on rotational thromboelastometry (ROTEM) is associated with poor outcomes in adults, however this relationship is poorly understood in the pediatric population. We sought to define thresholds for product-specific transfusion and evaluate the prognostic efficacy of ROTEM in injured children. METHODS Demographics, ROTEM, and clinical outcomes from severely injured children (age < 18 years) admitted to a level 1 trauma center between 2014 and 2018 were retrospectively analyzed. Receiver operating characteristic curves were plotted and Youden indexes were calculated against the endpoint of packed red blood cell (PRBC) transfusion to identify thresholds for intervention. ROTEM parameters were compared against the clinical outcomes of mortality or disability at discharge. RESULTS Ninety subjects were reviewed. Increased EXTEM (tissue factor-triggered extrinsic pathway) clotting time (CT) >84.5 sec (p=0.049), decreased EXTEM amplitude at 10 minutes (A10) <43.5 mm (p=0.025), and decreased EXTEM maximal clot firmness (MCF) <64.5 mm (p=0.026) were associated with need for blood product transfusion. Additionally, EXTEM CT >68.5 seconds was associated with mortality or disability at discharge. CONCLUSION Coagulation dysregulation on thromboelastometry is associated with disability and mortality in children. Based on our findings, we propose ROTEM thresholds: plasma transfusion for EXTEM CT>84.5 seconds, fibrinogen replacement for EXTEM A10<43.5 mm, and platelet transfusion for EXTEM MCF<68.5 mm.
