(0:00:00) - Military Wound Care Evolution (14 Minutes)

Retired Army Colonel Dr Evan Renz, a General/Trauma Surgeon with extensive experience in training and working at the US Institute of Surgical Research's Burn Unit in San Antonio, provides insights into the evaluation and treatment of complex wounds. He emphasizes the critical importance of documenting and learning from our past to help prepare us for future conflicts and to make sure that these lessons are included in military medical training opportunities. We discuss the changes in wound management from World War II to today, from the importance of hemorrhage control and debridement to advancements in medications and technologies improving wound care.

(0:13:59) - Wound Management in Damage Control (15 Minutes)

Dr. Evan Renz discusses the importance of wound management in damage control resuscitation. He shares his experience with his first use of a Wound Vac in 1997 and how the use of negative pressure wound therapy evolved over time. We explore the special considerations surgeons must take when evaluating a wound where a tourniquet is in place and how these decisions can help preserve the patient's hemodynamic stability.

(0:28:44) - Burn Center and Wound Care Management (17 Minutes)

Dr. Renz explains that isolated burn injuries do not require prophylactic antibiotics; however, traumatic combat wounds should be treated with an initial dose of antibiotics in addition to a Tetanus booster. Dr. Renz shares his experience with the use of the Wound Vac in the Burn Center and the key questions that he would ask when taking calls for burn management care. He also explains the importance of avoiding over-resuscitation and how to initiate and adjust fluid for the patient. Finally, he outlines the care that the patient would receive in regard to their wounds once they reach Role 4 or 5 facilities.

(0:46:13) - Decisions in Combat Wound Closure (7 Minutes)

Dr. Evan Renz shares his experience with the Emergency War Surgery manuals and the use of Wound Vacs in the field. We also discuss the importance of repeating a primary and secondary survey with each transfer of care and how to identify when a wound can or should be closed primarily or covered by a flap or graft. Finally, Dr. Renz speaks to the importance of passing on knowledge and training in the advances of technology so that it is not forgotten.
