Abstract

Background: Most authors have recommended treating extravasation during sclerotherapy by infiltrating the area with 0.9% sodium chloride and/or procaine.

Objective: To evaluate interventions in the prevention of necrosis following intradermal injection of 23.4% sodium chloride and 3% sodium tetradecyl sulfate.

Methods: Following intradermal 23.4% sodium chloride (Study I) or 3% sodium tetradecyl sulfate (Study II), subjects (Sprague-Dawley rats) received either no treatment or injections of 0.9% sodium chloride, sterile water, 1% procaine, or hyaluronidase. Groups were compared regarding incidence and size of necrosis.

Results: In study I, hyaluronidase treated groups had significantly fewer and smaller areas of necrosis than Other groups. In study II, the hyaluronidase group developed significantly fewer ulcers than the 0.9% sodium chloride group. The 0.9% sodium chloride group had significantly larger ulcers than Other groups.

Conclusion: In the model studied, hyaluronidase was the only effective treatment in the prevention of necrosis. Following 3% sodium tetradecyl sulfate, 0.9% sodium chloride was associated with larger ulcers than Other groups.
