Haemodynamics of the radial forearm flap
Abstract:
An electromagnetic blood flow meter was used to study blood flow to the radial forearm flap intra-operatively in 20 patients. Blood flow correlated more significantly with surface area than with weight. Both antegrade and retrograde flow were measured and showed no significant difference. Temperature affected blood flow significantly (P less than 0.01) as did sympathetic block (P less than 0.01). The venous drainage of the flap was studied in five cases. Both superficial and deep systems were equally capable of draining the flap.

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
