title: Use of Doppler ultrasound in performing percutaneous cannulation of the radial artery.
abstract: Doppler ultrasound has been used extensively in assessing adequacy of circulation. We have found it to be convenient in the identification of blood flow, particularly in hypotensive states where percutaneous radial artery cannulation of the vessel is tedious and difficult to perform. The technique is simple, atraumatic, and usually successful.
