Krishnan Raghavendran is Professor of Surgery at the University of Michigan Medical School, Division Chief of Acute Care Surgery, Director of the Michigan Center for Global Surgery, and a trauma, critical care, and general surgeon.
Raghavendran attended medical school at Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER) in Pondicherry, India and graduated in 1985. [1]
Upon completion of his medical degree in 1991, he moved to Bronx-Lebanon Hospital Center to begin his residency in surgery until 1994, when he moved to Detroit to complete his residency in general surgery at Henry Ford Hospital, which he finished in 1996. [1] [2] He later completed a fellowship in Surgical Critical Care at Brown University in Providence, Rhode Island in 2000.
Raghavendran became an attending trauma surgeon at University at Buffalo, SUNY. In July 2007, he was promoted to associate professor.
In 2008, he was recruited to the University of Michigan and became an associate faculty member at the University of Michigan Medical School. Raghavendran is currently the program director for the University of Michigan's fellowship in surgical critical care and acute care surgery.
Raghavendran has a long-standing interest in global health is one of the lead physicians for the University of Michigan India collaborative, [3] part of the Global REACH program, where he focuses on the delivery of trauma care in India. [4] He has also been working on similar collaborative efforts in Ethiopia and Taiwan. [2] [5] He was appointed the Director of the Michigan Center for Global Surgery upon its founding in 2017. [6] [7]
He has specialized in acute care surgery, including trauma and care of the critically ill. His main areas of publication have included venous thromboembolism (VTE), aspiration-induced lung injury, pulmonary surfactant biology, and decompressive craniectomy for traumatic brain injury (TBI). [8] He has also been involved in the study of TBI and trauma systems in the global arena. [1]
Raghavendran has been continuously funded by the National Institutes of Health (NIH) since 2006 by the National Institute of General Medical Sciences (NIGMS) and by an R0-1 award from the National Heart, Lung, and Blood Institute (NHLBI). [1] [4] His research has focused on direct forms of lung injury including lung contusion and gastric aspiration-induced lung injury. His laboratory research has focused primarily on studying the chemokine modulation in inflammatory mechanisms associated with both lung contusion and its interaction with gastric aspiration.
He has published more than 100 peer-reviewed articles and has been cited more than 1,000 times. [9]
Additional areas of interest center on the role of Toll-like receptors and micro RNA in the pathogenesis of acute inflammatory response in direct forms of lung injury. The focuses of his clinical interests are on the development of therapeutic strategies to mitigate the progression of these risk factors to ARDS, surfactant replacement therapy, and ventilator-associated pneumonia. He also collaborates with in the areas of ultrasound biology, single cell imaging and microfluidic studies of liquid-air interface. [1]
A pulmonary alveolus, also known as an air sac or air space, is one of millions of hollow, distensible cup-shaped cavities in the lungs where pulmonary gas exchange takes place. Oxygen is exchanged for carbon dioxide at the blood–air barrier between the alveolar air and the pulmonary capillary. Alveoli make up the functional tissue of the mammalian lungs known as the lung parenchyma, which takes up 90 percent of the total lung volume.
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). For those who survive, a decreased quality of life is common.
An injury is any physiological damage to living tissue caused by immediate physical stress. Injuries to humans can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries.
Am Timan is a city in Chad and is the capital of the region of Salamat. Most of economy comes from Salamat region such as fish, vegetables and anomalies meat etc. In Arabic, Am Timan means "mother of twins". As the capital of the prefecture, it has the area of many towns and villages around it including Zakuma national park. The city has no university but there are schools and colleges, and a clinic, and hosts a large market day and holiday celebrations.
A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity ranging from mild traumatic brain injury (mTBI/concussion) to severe traumatic brain injury. TBI can also be characterized based on mechanism or other features. Head injury is a broader category that may involve damage to other structures such as the scalp and skull. TBI can result in physical, cognitive, social, emotional and behavioral symptoms, and outcomes can range from complete recovery to permanent disability or death.
Blunt trauma, also known as blunt force trauma or non-penetrating trauma, describes a physical trauma due to a forceful impact without penetration of the body's surface. Blunt trauma stands in contrast with penetrating trauma, which occurs when an object pierces the skin, enters body tissue, and creates an open wound. Blunt trauma occurs due to direct physical trauma or impactful force to a body part. Such incidents often occur with road traffic collisions, assaults, and sports-related injuries, and are notably common among the elderly who experience falls.
A chest injury, also known as chest trauma, is any form of physical injury to the chest including the ribs, heart and lungs. Chest injuries account for 25% of all deaths from traumatic injury. Typically chest injuries are caused by blunt mechanisms such as direct, indirect, compression, contusion, deceleration, or blasts caused by motor vehicle collisions or penetrating mechanisms such as stabbings.
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment. The penetrating object may remain in the tissues, come back out the path it entered, or pass through the full thickness of the tissues and exit from another area.
A pulmonary contusion, also known as lung contusion, is a bruise of the lung, caused by chest trauma. As a result of damage to capillaries, blood and other fluids accumulate in the lung tissue. The excess fluid interferes with gas exchange, potentially leading to inadequate oxygen levels (hypoxia). Unlike pulmonary laceration, another type of lung injury, pulmonary contusion does not involve a cut or tear of the lung tissue.
A pulmonary laceration is a chest injury in which lung tissue is torn or cut. An injury that is potentially more serious than pulmonary contusion, pulmonary laceration involves disruption of the architecture of the lung, while pulmonary contusion does not. Pulmonary laceration is commonly caused by penetrating trauma but may also result from forces involved in blunt trauma such as shear stress. A cavity filled with blood, air, or both can form. The injury is diagnosed when collections of air or fluid are found on a CT scan of the chest. Surgery may be required to stitch the laceration, to drain blood, or even to remove injured parts of the lung. The injury commonly heals quickly with few problems if it is given proper treatment; however it may be associated with scarring of the lung or other complications.
Tracheobronchial injury is damage to the tracheobronchial tree. It can result from blunt or penetrating trauma to the neck or chest, inhalation of harmful fumes or smoke, or aspiration of liquids or objects.

Steven R. Flanagan is a nationally renowned expert in the field of traumatic brain injury (TBI) and is professor and chairman of the Department of Rehabilitation Medicine at the New York University School of Medicine, and the medical director of the Rusk Institute of Rehabilitation Medicine at the NYU Langone Medical Center.
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.
Robert Bartlett is an American physician and medical researcher who is credited with developing a lifesaving heart-lung technology known as extracorporeal membrane oxygenation (ECMO). He is an emeritus professor of surgery at the University of Michigan Medical School.
Ibolja Cernak is an American researcher in blast wave injury. Cernak concluded in the 1990s that soldiers who had been subjected to blasts were suffering from traumatic brain injury (TBI), while most still considered their invisible injuries to be Post Traumatic Stress Syndrome (PTSD), and to be psychological rather than physical. Cernak is Chair of Military and Veterans’ Clinical Rehabilitation at the Faculty of Rehabilitation at the University of Alberta.

LFR International is an American international nonprofit organization focused on prehospital emergency medical research and emergency medical services development in sub-Saharan Africa. LFR launches sustainable prehospital emergency care programs in resource-limited settings of low-income countries without formal emergency medical services by collaborating with local governments and stakeholders to train lay first responders.
The Lay First Responder Model, or LFR Model, uses motorcycle taxi drivers trained as first responders to provide basic prehospital emergency care in resource-limited settings of low- and middle-income countries. First published in the World Journal of Surgery in 2018, it was initially demonstrated in Uganda in 2016. Since its creation, the lay first responder model has also been deployed across Chad and Sierra Leone.
Peter G. Delaney is the Executive Director of LFR International and a road safety researcher responsible for the Lay First Responder Model of emergency medical services development in resource-limited countries, awarded the Prince Michael International Road Safety Award in 2020.
