Influence of the mode of ventilation on ketamine/xylazine requirements in rabbits.

Objective: To evaluate the effect of the mode of mechanical ventilation (MV) on the dose of intravenous anesthetic during 3 hours of ketamine/xylazine anesthesia.

Study Design: Prospective laboratory study.

Animals: Sixty-one adult male New Zealand White rabbits.

Radial pulse character relationships to systolic blood pressure and trauma outcomes.

Background: Patient measurements that do not require monitoring equipment may be the only way to evaluate casualties in austere conditions to determine treatment and transport priority. Objective. To test the hypothesis that palpable pulse characteristics in the radial artery would estimate systolic blood pressure (SBP) and predict outcome in trauma patients.
