Abstract
Nowadays, chest trauma becomes the third behind head and extremity trauma in major accidents (Joseph and Mattox, 1980).
Thoracic injury is the cause of death in approximately one quarter of all trauma victims and is a frequent factor in the morbidity encountered in multiply injured patients. But advances in management of major chest injuries have been numerous and mortality has decreased in many centers (Livingston and Richardson, 1990).
Motor vehicle accidents in the most common blunt mechanism others include motor cycle accidents, fall from a high and assaults with blunt objects such as fists of base ball bats, increasing Traffic speed has increase the frequency of severe thoracic injury suffered from motor vehicle accidents; chest injuries occur approximately 25% of motor vehicle accidents victims (Locicero and Mattox, 1989).
Regardless to the mechanism of injury, chest trauma is common and take different forms. Some injuries such as fracture ribs, blunt diaphragmatic injuries can be subtle in theft initial presentation and are diagnostic dilemmas. Some other thoracic injuries such as tension pneumothorax are among the most immediate serious and life threatening of all traumatic injuries (Cahloon et al., 1992).
Blunt thoracic injuries usually handled in most centers who are can not claim wide experience of their management. In addition, the majority of hospitals in many countries do not have on-site cardiothoracic facilities and many of these patients are initially managed by doctors from other specialties so, it is vital that all units which deal with such patients must look critically at their own results in order to audit their performance and correct deficiencies in training (Sayers, et al., 1994).
The development of anaesthia, antibiotics, radiology mechanical ventilators and advanced surgical procedures permits more aggressive surgical managements trauma (Wailer, 1985).
AIM OF THE WORK:
• To study blunt chest trauma regarding the main clinical manifestation and signs and different lines of managements.
• To select proper line of resuscitation and the proper surgical procedure in patients with blunt chest trauma.
