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.
