Articaine versus Levobupivacaine with and without Hyaluronidase in peribulbar anesthesia for cataract surgery

Abstract

Regional anesthesia is most commonly used for ophthalmic procedures. Various techniques and combinations for local anesthetics have been established and frequently used over the years with the aim of establishing a superior protocol. As an almost exclusive day case procedure, cataract extraction needs anesthetic management that is effective, safe, economic and not time consuming. This improves patient satisfaction and assures minimal exhaustion of hospital resources and facilities. The single injection medial canthus peribulbar block utilized in this study is a recent modification of the peribulbar techniques previously used. It offers extended safety due to the use of short needles and the need for a single injection only. It also requires less total volume of local anesthetics which may be of little benefit on single patient bases but would be more cost efficient on a larger scale. Articaine is an amide local anesthetic that has been a
