What is PTC
Primary Trauma Care
is a 2 day course followed by a one
day instructors’ course,
training doctors and nurses in the
acute management of the severely
injured patient
PTC
PTC Mission Statement
• To train doctors & nurses to treat
severely injured patients quickly &
systematically
• To use what equipment is available, to
prioritise and treat patients safely
• To train clinicians to teach PTC
principles in their hospitals
PTC
Objectives of a PTC
2 day course
- demonstrate the systematic assessment
& treatment of the severely injured
patient
- to train you in the knowledge, skills and
attitudes of the PTC principles
- To consider how these PTC principles
can be adapted to your hospital

Most Frequent Reasons for Failure
to Evacuate a Pneumothorax
Rapidly & to Completely Expand the
Lungs
1) Improper connections or leaks in the external tubing or water-seal collection apparatus
2) Improper position of the chest tube(s)
PTC
Most Frequent Reasons for Failure to
Evacuate a Pneumothorax Rapidly & to
Completely Expand the Lungs
3) Occlusion of bronchial by secretions
or a foreign body
4) A tear of one of the large bronchi
5) A large tear of the lung parenchyma
PTC
Most Frequent Reasons for Failure to
Evacuate a Pneumothorax Rapidly & to
Completely Expand the Lungs
• If a pneumothorax persists in spite of 1 or 2 well-placed chest tubes & there is a large leak, emergency bronchoscopy should be performed to clear the bronchi & identify any damage to the tracheobronchial tree that may need repair.
PTC
Most Frequent Reasons for Failure to
Evacuate a Pneumothorax Rapidly & to
Completely Expand the Lungs
• High-frequency oscillation is indicated for bronchopleural fistula & may substantially slow the leak.
• Continued large air leakage & failure of the lung to expand adequately in spite of these measures is an indication for early thoracotomy to control the air leak.
PTC
