Modified peribulbar anesthesia

ABSTRACT

Posterior peribulbar anesthesia is a safe and an effective alternative to retrobulbar anesthesia for ophthalmic surgery 10 ml of an anesthetic mixture formed of Xylocaine 2% and Marcaine 0.5% mixed in a ratio 1 1, with Hyaluronidase 1500 IU was injected along the superior and inferior orbital walls. The ocular massage was applied for 10 minutes at pressure of 35 mmHg. A booster dose was injected whenever judged necessary. This technique was applied to 36 patients scheduled for intraocular surgery, and compared to 15 patients receiving the standard technique. 3 parameters were used to evaluate the efficacy of the technique Lid akinesia, eye movement and intraocular pressure. The success rate reached 83.3% increasing to 94% after giving a booster dose to the residual cases compared to a rate of 86.6% in the standard technique
