Direct Arterial Pressure Monitoring from the Dorsalis Pedis Artery

W. E. SPOEREL 1, P. DEIMLING 1, and R. AITKEN 1

1 Department of Anaesthesia, University of Western Ontario and University Hospital, London, Canada

The arteria dorasalis pedis, when clearly palpable, is a suitable artery for direct arterial blood pressure monitoring. The systolic pressure and the pulse pressure are likely higher in the dorsalis pedis artery when compared to the radial artery but there is no clinically signigicant difference in mean pressures. In plethysmographic studies it was found that in 16 per cent of the patients examined the pulse in the second tow disappeared after occulstion of the dorsalis pedis artery indicationg that it carried the main blood supply to the toes. Although no complications have resulted from cannulation of the dorsalis pedis artery in our practise, some caution is in order and preliminary testing may advisable even if the posterior tibial artery is distinctly palpable.
