DCR Local anesthesia (A new technique)

Abstract

In DCR local anesthesia achieves dual purpose. Firstly, it helps in anesthesia. Secondly, Adrenaline added to the anesthetic agent creates decongestion, which helps in an avascular operation field. The old technique involves an injection of large amount of anesthetic agent, which can result in lignocaine reaction, and adrenaline associated problems. In the new technique only 1.5-2.0 ml of local anesthetic agent is injected which is highly safe and effective. There is also minimal distortion of local anatomy. In this study, two hundred and sixty five patients were given local anesthesia with new technique. Only six needed to have their anesthesia repeated, sixteen had a persistent ooze. No one had adrenaline related problems. This technique is a safe and effective way of providing anesthesia for DCR.
