“Digital Diffusion” Technique for the Administration of Local Anesthetic in Eyelid Surgery

  • Rona Z. Silkiss


My preferred technique for the administration of local anesthetic has been dubbed “digital diffusion.” This technique involves the administration of a 50/50 mixture of 2% xylocaine with 1 : 100,000 epinephrine, 0.5% marcaine with 1 : 200,000 epinephrine combined with NaHCO3 and hyaluronidase. We add 0.5 ml of NaHCO3 to 9 ml of the local mixture and 0.5 ml or less of the hyaluronidase to a total of 10 ml.
