              Development of Blood Collection, Storage, and
              Transport Protocols in Austere Environments
              The isolation of active working dogs indicates that the most
              effective way to source canine blood is to collect it at a larger
              facility and transport it to more austere locations for storage
              and potential use. This concept is new to the HOA, so we
              sought to develop a local standard operating procedure (SOP)
              to fill this gap in canine casualty care. This initiative started
              as a request from canine handlers in preparation for high-risk
              operations and has transitioned to regularly scheduled collec-
              tion at a central location with a large repository of MWDs,
              followed by distribution to all outstations housing MWDs.

              For routine canine whole blood (CWB) collections, donors
              are selected from those assigned to HOA units and residing at
              Camp Lemonnier, Djibouti (CLDJ), either long-term or tran-
              siently.  Most  MWDs  are  great  candidates  for  this  program
              because of consistent veterinary health screenings and disease
              prevention measures. Donors are screened using the current
                      9
              guidelines.  An extensive history is taken to ensure no lapses
              in monthly parasite prevention as well as awareness of current
              medications, travel history, date of last donation, and previ-
              ous transfusions. Physical examination and lab diagnostics
              are performed to screen for vector- and nonvector-borne in-
              fectious diseases; tests include blood smear, fecal examination,   via aseptic jugular venipuncture using standard sterile tech-
              urinalysis, complete blood count, and blood chemistry anal-  niques. Midazolam and ketamine are used for additional se-
              ysis. Immediate disqualifying characteristics include canines   dation if necessary. Dexmedetomidine may cause decreased
