Study Arms:
- 1 (Type: EXPERIMENTAL): Early conversion from endotracheal intubation to percutaneous tracheostomy for ventilator support of trauma patients with severe brain injury
- 2 (Type: ACTIVE_COMPARATOR): Conventional conversion from endotracheal intubation to percutaneous tracheostomy for ventilator support of trauma patients with severe brain injury

Based on this trial design, predict the completion outcome and termination type (if applicable).
