LOCAL ANESTHESIA FOR VITREO-RETINAL SURGERY

Abstract

Local anesthesia is used as a component of general anesthesia or self-sufficient technique of perioperative analgesia at the vitreo-retinal surgery. Its popularity originates from safety and simplicity of regional techniques which provide efficient analgesia, perfect surgical field and fast recovery. Most of injection techniques of ophthalmic regional anesthesia are single shot methods which could not provide effective analgesia in some patients who required anesthesia for a prolonged period. Implementation of catheter technique in daily practice could be solution to this problem. Infusion of local anesthetic through catheter possesses all advantages of single-shot techniques and provides virtually unlimited duration of analgesia.
