Background:
Damage control techniques have been developed and applied to abdominal, vascular and thoracic injuries. Thoracic damage control techniques must be rapid and simple.
Methods:
This report describes the successful use of pulmonary hilum twist as an effective damage control technique to control hemorrhage for severe lung trauma.
Results:
The procedure involves division of the inferior pulmonary ligament then anterior rotation of the lower lobe over the upper lobe. The technique can be utilized in multiple settings including the emergency center, operating room, and during resuscitation. When vascular occlusion is maintained throughout resuscitation in the intensive care unit, pneumonectomy most likely will be required, but can be performed when the physiologic parameters have improved. Complications are similar to pneumonectomy and can include right-side heart failure, dysrrythmias, and hypoxia.
Conclusions:
Pulmonary hilar twist is an effective technique that should be considered when a damage control approach is needed.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
