Management of pulse oximeter probe–induced finger injuries in children: report of two consecutive cases and review of the literature


      Pulse oximetry is a standard noninvasive procedure for monitoring arterial oxygen saturation. Finger injuries related to pulse oximeter use have been reported as chemical or thermal burns, sun-tanning, pressure erosion, sensory loss, and gangrene. The mechanisms of these complications have not been definitively explained; but pressure ischemia, prolonged use, overheating of the probe, inappropriate use of the probe, and short circuiting are considered to be the main factors. We describe 2 cases of pulse oximeter probe–induced finger injuries, propose the possible mechanisms and factors related to the injury, and discuss the management.
