ABSTRACT:
A method and apparatus in which an anesthesia catheter is inserted into the epidural space of the patient. A blood soluble dye mixed with a local anesthetic is injected through the catheter and into the patient. A transducer clip is positioned on the finger of the patient for monitoring the light responsive characteristics of the patient's blood. A transducer signal is fed to a microprocessor for generating a real time display for indicating to the anesthesiologist that the dye, and therefore the local anesthetic, is present in the bloodstream.
