[A rare complication of conduction anesthesia in the treatment of finger injury].

At the present time novocain still remains the anesthetic of choice in ambulatory surgery and traumatology. In practical work the 2% and 0.5% solutions are used. The 2% solution of novocain can in some cases (in patients prone to angiodystonic reactions) cause a persistent spasm of digital arteries that results in irreversible alterations in finger tissues down to the development of gangrene. This fact was confirmed in experiments with 2% solutions of novocain. It is proposed to follow the recommendations on using the 0.5% and 1% solutions of novocain for regional anesthesia in fingers. Such anesthetics as Lidocain and Trimecain should be used more widely since they possess more pronounced and continuous anesthetizing properties.
