Background:
Predicting the outcome of blunt chest trauma by scoring systems is of utmost value. We aimed to assess the role of the chest trauma scoring system (CTS) in predicting blunt chest trauma outcomes among Egyptians.
Methods:
A prospective observational study included 45 patients admitted to the cardiothoracic emergency unit of Al-Azhar University hospitals. We documented their demographic data, history, cause and mode of trauma, vital parameters, and necessary investigations (e.g., chest X-ray and Computed Tomography) when the patient was admitted to the cardiothoracic department. All patients were assessed using the chest trauma scale (CTS) and followed up till death or discharge.
Results:
The patient's age ranged between 18 to 76 years (mean 42.67 years). Eighty percent were males, and 48% needed mechanical ventilation (MV). The period of MV was ranged from 1 to 5 days (mean 2.81 days). Twenty-two patients had pneumonia. Eight patients died with a chest trauma scale ranging from 2 to 12 with a median of 6. About 87 percent of patients had unilateral lesions, and 5 had criminal causes. Road traffic accidents were the most typical cause of trauma (60%). There was a significant relation between mortality among the studied patients and each MV, length of ICU duration, chest trauma scale, laterality of trauma, and associated injuries. There was a statistically significant relation between the chest trauma scale and the need for MV, the timing of MV, the presence of pneumonia, and mortality.
Conclusion:
CTS ≥ 6.5 can predict mortality with 100.0% sensitivity, specificity of 62.2%, and accuracy of 68.9%. However, a score of ≥ 5.5 can predict the development of pneumonia with a sensitivity of 81.8%, specificity of 78.3%, and accuracy of 80%.

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...
