Abstract

Military working dogs (MWDs) are force multipliers that are at risk for severe trauma when employed on the battlefield. When in severe hemorrhagic shock, MWDs require both oxy-gen-carrying capacity and replacement of vascular volume and coagulation factors. The objective of this study was to evaluate the hemostatic capacity of canine freeze-dried plasma (cFDP) with a Food and Drug Administration (FDA)-approved hemo-globin-based oxygen carrier (HBOC) in an in vitro model of re-suscitation. Whole blood (WB) was collected from 10 MWDs, and these samples were diluted by 10%, 25%, or 40% with either cFDP (reconstituted with water), HBOC, cFDP (reconsti-tuted with HBOC), or an equal volume of a 1:1 ratio of cFDP (reconstituted with water) and HBOC. Hemostatic parameters were minimally changed based on evaluation of prothrombin time, activated partial thromboplastin time, fibrinogen and thromboelastography at the 10% and 25% dilutions, and parameters consistent with a hypocoagulability were seen at di-lutions of 40%. Based on the results of this study, additional research is warranted to determine if cFDP reconstituted with HBOC is a viable resuscitation product in canine trauma.
