A comparison of two double‐injection techniques for peribulbar block analgesia: infero‐temporal plus supero‐medial vs. infero‐temporal plus medial‐percaruncular*

Abstract

Compared with the inferior-superior technique, the inferior-medial combination achieved more rapid ocular akinesia with less need for supplementation, but induced less efficient lid akinesia and had a propensity to cause iatrogenic subconjunctival hemorrhage. The latter complication is considered by our surgeons to be a contraindication to the inferior-medial technique in patients undergoing trabeculectomy.

Comparison of orbital muscle akinesia caused by rocuronium versus hyaluronidase mixed to the local anesthetic in single injection peribulbar block for cataract surgery

“…The block is usually done using a single or double injection technique. [ 21 ] However, the choice between either single or double injection technique is based on the volume of the orbit, degree of required akinesia, ophthalmologist experience and preference of the anesthesiologist. [ 22 ] This study we used the single injection peribulbar block technique which is as effective as the standard two injection peribulbar block during eye surgery.…”
