Good management of acute stroke is dependent on time and expertise. In Germany emergency medical care by ambulance services sometimes occurs without an emergency physician being sent to the scene. By reviewing current literature the question of patient care in the ambulance with or without an emergency physician is discussed. Presence of an emergency physician at the scene results in high diagnostic accuracy, allows for invasive procedures to be carried out, and enables referral to a specialist centre with a stroke-unit. The "rendezvous" system of separate deployment of patient ambulance and emergency physician allow flexible assignment of the physician resulting in short response times. Current research does not support a turn away from the deployment of an emergency physician in cases of acute stroke.
