[Evaluation of palmar collateral circulation with the Oxygenmet oxygen saturation measurement device].
Assessment of collateral circulation of the palmar arcade prior to percutaneous radial artery cannulation is necessary because a thrombosing radial artery together with insufficient collateral circulation may lead to gangrene of the hand. A new method for assessment of collateral circulation of the palmar arcade by use of a spectrophotometric monitoring device for arterial oxygen saturation is described. This method is contrasted with current methods (Allen's test, Brodsky's test, ultrasound Doppler).
