Overview
Historical Perspective
In 1761, the Italian anatomist Giovanni Battista Morgagni was first to describe a lung injury that was not accompanied by injury to the chest wall overlying it. The French military surgeon Guillaume Dupuytren is thought to have coined the term pulmonary contusion in the 19th century.[1] However, it was not until the early 20th century that pulmonary contusion and its clinical significance began to receive wide recognition.[2] With the use of explosives during World War I came many casualties with no external signs of chest injury but with significant bleeding in the lungs.[2] Studies of World War I injuries by D.R. Hooker showed that pulmonary contusion was an important part of the concussive injury that results from explosions.[2]
Pulmonary contusion received further attention during World War II, when the bombings of Britain caused blast injuries and associated respiratory problems in both soldiers and civilians. Also during this time, studies with animals placed at varying distances from a blast showed that protective gear could prevent lung injuries. These findings suggested that an impact to the outside of the chest wall was responsible for the internal lesions. In 1945, Buford and Burbank described what they called "wet lung", in which the lungs accumulated fluid and were simultaneously less able to remove it. They attributed the respiratory failure often seen in blunt chest trauma in part to excessive fluid resuscitation, and the question of whether and how much to administer fluids has remained controversial ever since.
During the Vietnam War, combat again provided the opportunity for study of pulmonary contusion; research during this conflict played an important role in the development of the modern understanding of its treatment. The condition also began to be more widely recognized in a non-combat context in the 1960s, and symptoms and typical findings with imaging techniques such as X-ray were described. Before the 1960s, it was believed that the respiratory insufficiency seen in flail chest was due to "paradoxical motion" of the flail segment of the chest wall (the flail segment moves in the opposite direction as the chest wall during respiration), so treatment was aimed at managing the chest wall injury, not the pulmonary contusion.[3] For example, positive pressure ventilation was used to stabilize the flail segment from within the chest. It was first proposed in 1965 that this respiratory insufficiency is most often due to injury of the lung rather than to the chest wall, and a group led by J.K. Trinkle confirmed this hypothesis in 1975.[4] Hence the modern treatment prioritizes the management of pulmonary contusion.[2] Animal studies performed in the late 1960s and 1970s shed light on the pathophysiological processes involved in pulmonary contusion.
