[The Doppler palm test].
In 384 hands the patency of the arterial arch was investigated by means of both the Allen test and the Doppler palmar arch test as developed by the authors. While the Allen test is purely subjective and gives a high proportion of false results especially in shocked patients, the Doppler palmar arch test is based on two objective criteria: 1. Demonstration of reversed flow in the distal section of the radial artery on proximal compression. 2. Demonstration of pulsatile flow in the radial thumb artery even on compression of the radial artery. The Doppler palmar arch test eliminates all negative aspects of the Allen test and is therefore definitely more reliable than the latter. It is easy to perform for investigators having little experience with Doppler sonography. The time consumed is not greater than with the Allen test.
