Todd E. Rasmussen, MD, FACS is an American professor and Vice Chair for Education in the Department of Surgery at Mayo Clinic, Rochester, and a Senior Associate Consultant in the Division of Vascular and Endovascular Surgery. [1] Prior to joining the Mayo Clinic, he had a 28-year career in the military, retiring as an Air Force Colonel in 2021. His most recent military assignment was as Associate Dean or Research at the Uniformed Services University of the Health Sciences and an attending surgeon at the Walter Reed National Military Medical Center.
A native of Kansas, Rasmussen completed his undergraduate degree at the University of Kansas and his medical degree at Mayo Medical School (1993), followed by surgical training at Wilford Hall Medical Center at Lackland Air Force Base and vascular surgery specialty training at Mayo Clinic. [1] [2]
Rasmussen had been assigned to Andrews Air Force Base just before September 11, 2001, and soon after began caring for the injured returning from Afghanistan at Walter Reed Army Medical Center. He began a series of deployments to the Air Force Theater Hospital on Balad Air Base [3] as well as Bagram Air Base and the Afghan National Army Hospital in Kabul, Afghanistan. During this time in the Air Force, he initiated a research and innovation program aimed at developing a better understanding of vascular injury, hemorrhage control and shock as well as new approaches to managing these conditions. [4]
Rasmussen has led training missions in Morocco, Pakistan, and Russia, and his research efforts have resulted in hundreds of publications, including two textbooks, the Handbook of Patient Care in Vascular Diseases and the third and fourth editions of Rich's Vascular Trauma. [5] [6] He co-authored "Vascular Injury Rates in the Wars in Iraq and Afghanistan", in which he wrote that the frequency of vascular injury on the battlefield has increased by a factor of five between Vietnam and the later wars. [7] [8] Rasmussen was also one of the investigators in the Military Application of Tranexamic Acid in Trauma Resuscitation Study (MATTERS), which was a collaboration with British researchers on the use of tranexamic acid (TXA) in patients with severe bleeding. [9] The study indicated that patients treated with TXA survived twice as often as those who did not receive the drug. [10] [11]
Rasmussen is a co-inventor of resuscitative endovascular balloon occlusion of the aorta (REBOA), a minimally invasive approach used to sustain blood pressure and control bleeding in severely injured and shocked patients. [12] The ER-REBOA catheter has been used thousands of times in the U.S. and around the world. [13] [14]
In 2019, Rasmussen led a team of military surgeons at the Walter Reed National Military Medical Center as the first in the Military Health System (MHS) to implant a human acellular vessel, or HAV, into a patient who was in danger of losing his leg from vascular disease. [15] Rasmussen had previously worked in support of the research and development of this bioengineered blood vessel which has significant potential to be used in the management of wartime vascular injury.
Rasmussen was a 2019–2020 Association of American Medical Colleges (AAMC) Council of Deans fellow, [16] and in February 2020 he delivered the Peter Safar lecture at the Society of Critical Care Medicine in Orlando, Florida. [17] In 2021, Rasmussen was selected to serve on the board of the National Museum of Civil War Medicine. [18] Following his retirement from the Air Force he joined the Division of Vascular and Endovascular Surgery at the Mayo Clinic in Rochester, Minnesota. [1]
Rasmussen served as Deputy Commander of the Institute of Surgical Research from 2010 to 2013 and then moved to direct the larger Department of Defense Combat Casualty Care Research Program at Fort Detrick, Maryland. His awards include the Gold Headed Cane for distinction in clinical and academic practice, the NATO Dominique Jean Larrey Award for Excellence in Military Surgery, and in 2015, he was recognized as a Hero in Medicine by the Center for Public-Private Partnerships. [18] [19]
Rasmussen has contributed to articles published in USA Today , [20] the Health Affairs blog [4] and The New England Journal of Medicine . [21]
Bleeding, hemorrhage, haemorrhage or blood loss is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties. The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery.
Battlefield medicine, also called field surgery and later combat casualty care, is the treatment of wounded combatants and non-combatants in or near an area of combat. Civilian medicine has been greatly advanced by procedures that were first developed to treat the wounds inflicted during combat. With the advent of advanced procedures and medical technology, even polytrauma can be survivable in modern wars. Battlefield medicine is a category of military medicine.
Vascular surgery is a surgical subspecialty in which vascular diseases involving the arteries, veins, or lymphatic vessels, are managed by medical therapy, minimally-invasive catheter procedures and surgical reconstruction. The specialty evolved from general and cardiovascular surgery where it refined the management of just the vessels, no longer treating the heart or other organs. Modern vascular surgery includes open surgery techniques, endovascular techniques and medical management of vascular diseases - unlike the parent specialities. The vascular surgeon is trained in the diagnosis and management of diseases affecting all parts of the vascular system excluding the coronaries and intracranial vasculature. Vascular surgeons also are called to assist other physicians to carry out surgery near vessels, or to salvage vascular injuries that include hemorrhage control, dissection, occlusion or simply for safe exposure of vascular structures.
Internal bleeding is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding. Severe internal bleeding into the chest, abdomen, pelvis, or thighs can cause hemorrhagic shock or death if proper medical treatment is not received quickly. Internal bleeding is a medical emergency and should be treated immediately by medical professionals.
Major trauma is any injury that has the potential to cause prolonged disability or death. There are many causes of major trauma, blunt and penetrating, including falls, motor vehicle collisions, stabbing wounds, and gunshot wounds. Depending on the severity of injury, quickness of management, and transportation to an appropriate medical facility may be necessary to prevent loss of life or limb. The initial assessment is critical, and involves a physical evaluation and also may include the use of imaging tools to determine the types of injuries accurately and to formulate a course of treatment.
Hypovolemic shock is a form of shock caused by severe hypovolemia. It could be the result of severe dehydration through a variety of mechanisms or blood loss. Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ failure.
Tranexamic acid is a medication used to treat or prevent excessive blood loss from major trauma, postpartum bleeding, surgery, tooth removal, nosebleeds, and heavy menstruation. It is also used for hereditary angioedema. It is taken either by mouth or by injection into a vein.
London's Air Ambulance Charity is a registered charity that operates a helicopter emergency medical service (HEMS) dedicated to responding to serious trauma emergencies in and around London. Using a helicopter from 08:00 to sunset and rapid response vehicles by night, the service performs advanced medical interventions at the scene of the incident in life-threatening, time-critical situations.
R Adams Cowley Shock Trauma Center is a free-standing trauma hospital in Baltimore, Maryland and is part of the University of Maryland Medical Center. It was the first facility in the world to treat shock. Shock Trauma was founded by R Adams Cowley, considered the father and major innovator of trauma medicine.
The following outline is provided as an overview of and topical guide to emergency medicine:
Trauma surgery is a surgical specialty that utilizes both operative and non-operative management to treat traumatic injuries, typically in an acute setting. Trauma surgeons generally complete residency training in general surgery and often fellowship training in trauma or surgical critical care. The trauma surgeon is responsible for initially resuscitating and stabilizing and later evaluating and managing the patient. The attending trauma surgeon also leads the trauma team, which typically includes nurses and support staff, as well as resident physicians in teaching hospitals.
Damage control surgery (DCS) is surgical intervention to keep the patient alive rather than correct the anatomy. It addresses the "lethal triad" for critically ill patients with severe hemorrhage affecting homeostasis leading to metabolic acidosis, hypothermia, and increased coagulopathy.
The 274th Forward Surgical Team (Airborne)—part of the 274th Forward Resuscitative and Surgical Detachment (Airborne)—is an airborne forward surgical team of the United States Army providing Level II care far forward on the battlefield. It was first constituted in 1944 and served in Europe during World War II. More recently it has been involved in relief operations following natural disasters and has undertaken several recent deployments to Iraq and Afghanistan. The 274th Forward Surgical Team was part of both the initial entry forces of Operation Enduring Freedom in 2001 and Operation Iraqi Freedom in 2003. Currently the unit falls under the command of the 28th Combat Support Hospital and is based at Fort Bragg, North Carolina.
Tactical Combat Casualty Care are the United States military guidelines for trauma life support in prehospital combat medicine, designed to reduce preventable deaths while maintaining operation success. The TCCC guidelines are routinely updated and published by the Committee on Tactical Combat Casualty Care (CoTCCC), which is part of the Defense Committees on Trauma (DCoT) division of the Defense Health Agency (DHA). TCCC was designed in the 1990s for the Special Operations Command medical community. Originally a joint Naval Special Warfare Command and Special Operations Medical Research & Development initiative, CoTCCC developed combat-appropriate and evidence-based trauma care based on injury patterns of previous conflicts. The original TCCC corpus was published in a Military Medicine supplement in 1996. TCCC has since become a Department of Defense (DoD) course, conducted by National Association of Emergency Medical Technicians.
Johannes Hoffmann is a German medical specialist in vascular surgery. Furthermore, he is professor and director of the clinic for vascular surgery and phlebology of the Elisabeth-Hospital Essen as well as head of the clinic for vascular surgery Essen. He is especially well known for his works on the key research areas of dialysis-shunt-surgery, hybrid surgery, endovascular procedures, postoperative management of coagulation, sepsis and ischemia.
Endovascular and hybrid trauma and bleeding management is a new and rapidly evolving concept within medical healthcare and endovascular resuscitation. It involves early multidisciplinary evaluation and management of hemodynamically unstable patients with traumatic injuries as well as being a bridge to definitive treatment. It has recently been shown that the EVTM concept may also be applied to non-traumatic hemodynamically unstable patients.
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally invasive procedure performed during resuscitation of critically injured trauma patients. Originally developed as a less invasive alternative to emergency thoracotomy with aortic cross clamping, REBOA is performed to gain rapid control of non-compressible truncal or junctional hemorrhage. REBOA is performed first by achieving access to the common femoral artery (CFA) and advancing a catheter within the aorta. Upon successful catheter placement, an occluding balloon may be inflated either within the descending thoracic aorta or infrarenal abdominal aorta. REBOA stanches downstream hemorrhage and improves cardiac index, cerebral perfusion, and coronary perfusion. Although REBOA does not eliminate the need for definitive hemorrhage control, it may serve as a temporizing measure during initial resuscitation. Despite the benefits of REBOA, there are significant local and systemic ischemic risks. Establishing standardized REBOA procedural indications and mitigating the risk of ischemic injury are topics of ongoing investigation. Although this technique has been successfully deployed in adult patients, it has not yet been studied in children.
