Background: We endeavored to develop clinically translatable nonhuman primate (NHP) models of severe polytraumatic hemorrhagic shock.

Methods: NHPs were randomized into five severe pressure-targeted hemorrhagic shock (PTHS) ± additional injuries scenarios: 30-min PTHS (PTHS-30), 60-min PTHS (PTHS-60), PTHS-60 + soft tissue injury (PTHS-60+ST), PTHS-60+ST + femur fracture (PTHS-60+ST+FF), and decompensated PTHS+ST+FF (PTHS-D). Physiologic parameters were recorded and blood samples collected at five time points with animal observation through T = 24 h.

Minimizing the pain or discomfort of research animals through refinement of surgical techniques is inherent in the humane use of animals in investigative studies. The current approach for intraperitoneal implantation of radiotelemetry devices in mice is a ventral midline incision. An optional surgical approach is a flank incision.

Non-human primates (NHP) are considered to be the most appropriate model for predicting how humans will respond to many infectious diseases. Due to ethical and monetary concerns associated with the use of NHP, rodent models that are as predictive of responses likely to be seen in human vaccine recipients are warranted. Using implanted telemetry devices, body temperature and activity were monitored in inbred and outbred mouse strains following administration of the live-attenuated vaccine for Venezuelan equine encephalitis virus (VEEV), V3526.

The experimental use of amphibian models in biomedical research increases yearly, but there is a paucity of reports concerning analgesic use in many of these species. In this study, buprenorphine given by intracoelomic injection and butorphanol added to the tank water were compared for analgesic effect in the eastern red-spotted newt after bilateral forelimb amputations. Newts undergoing anesthesia but not surgery and newts having surgery but not given analgesia postoperatively were used as control groups.

Background: Medics assigned to combat units have a notable paucity of trauma experience. Our goal was to provide intense trauma refresher training for the conventional combat medic to better prepare them for combat casualty care in the War on Terror.

Materials And Methods: Our Tactical Combat Casualty Care Course (TC3) consisted of the following five phases: (1) One and one-half-day didactic session; (2) Half-day simulation portion with interactive human surgical simulators for anatomical correlation of procedures and team building; (3) Half-day of case presentations and triage scenarios from Iraq/Afghanistan and associated skills stations; (4) Half-day live tissue lab where procedures were performed on live anesthetized animals in a controlled environment; and (5) One-day field phase where live anesthetized animals and surgical simulators were combined in a real-time, field-training event to simulate realistic combat injuries, evacuation problems, and mass casualty scenarios.
