Abstract Levarterenol (l-norepinephrine [Levophed]) bitartrate is one of the most commonly used pressor amines in the treatment of shock. However, a major disadvantage is the development of ischemic necrosis in areas of accidental extravasation. On the basis of clinical use, starting in 1954, it was demonstrated by one of us1 that, in such areas, the local vasoconstrictor effect could be counteracted by phentolamine (Regitine) methanesulfonate, an antiadrenergic drug. When 5-10 mg. of the latter drug, diluted in 20 cc. of water, was infiltrated subcutaneously throughout the area of ischemia, the pallor and coldness disappeared within five to seven minutes. Untreated areas became necrotic. Similar observations have been made by McGinn and his co-workers,2 who added hyaluronidase to the phentolamine solution. Pelner 3 cited a case in which hyaluronidase favored the spread of ischemia. He also reported that another antiadrenergic drug, piperoxan (Benodaine), had an action similar to that References 1.

Since the completion of this manuscript, 65 additional cases of shock have been treated with varying mixtures of levarterenol and phentolamine. Twenty-seven extravasations have occurred without any evidence of ischemic necrosis. Experiments on 36 rabbits demonstrated that as little as 2.5 mg. of phentolamine prevented necrosis invariably produced by solutions containing 8, 16, or 32 mg. of levarterenol per liter. 5.
