Advanced Trauma Life Support

As an ambulance physician, you and your crew are coming to a traffic accident. It is a crash of a passenger car into a solid obstacle. There was only a 29-year-old man in the driver's seat in the car. Looking into the interior of the vehicle, you can see the massive intrusion. He is now rescued by firefighters, has a neck collar and is placed on the spine board. He is conscious, complaining of pain in the left chest, abdomen and right leg. What will you do?
