Flail chest: pathophysiology and management

Thoracic trauma is an important cause of morbidity and mortality in the UK, frequently found in drivers of motor vehicles following high-speed accidents. One of the more serious injuries is a flail chest, particularly when there are also underlying pulmonary contusions. For many years the optimal therapeutic regimen for the management of this condition has remained somewhat controversial. More recently, the role of epidural analgesia, the use of non-invasive techniques of ventilation and identification of those who may benefit from surgical stabilisation have been more clearly defined.

Flail chest and pulmonary contusion

Flail chest is most often accompanied by a significant underlying pulmonary parenchymal injury and can be a life-threatening thoracic injury. Its management is often complicated by the other injuries it is frequently associated with. Similarly, mortality and morbidity are dictated most often by the associated injuries and findings. Its treatment is complex and should first be one of pain management, judicious fluid resuscitation, and excellent pulmonary toilet. In those patients requiring mechanical ventilatory support, or who require ipsilateral thoracocotomy, rib stabilization may be considered depending on a host of potentially conflicting indications and contraindications. At the end of this section are listed the current major recommendations and their levels of evidence.
