Improvement in Blood Flow and Diameter of the Postanastomotic Rat Tail Artery by Topical Application of Lidocaine in Varying Concentrations

Abstract

Prolonged spasm in small vessels is a major problem after microsurgical procedures. Topical agents applied to resolve these spasms have been the subject of many experimental studies. In this model we studied the effectiveness of various concentrations of lidocaine in resolving microvascular spasms induced by anastomosing the ventral rat tail artery.
