Efficacy of Local Anesthesia during External Dacryocystorhinostomy with 1:200,000 Adrenaline Versus 1:50,000 Adrenaline

Purpose: To compare the efficacy of local anesthesia during Dacryocystorhinostomy using xylocaine with 1:200,000 adrenaline versus 1:50,000 adrenaline. Study Design: Quasi experimental study. Place and Duration of Study: DHQ Hospital, Dera Ismail Khan, from January to December 2019. Material and Methods: We compared two different formulations of local anesthesia during Dacryocystorhinostomy in terms of efficacy of per-operative pain, bleeding and effectiveness of anesthesia. 50 patients fulfilling our inclusion criteria were divided in two groups each containing 25 patients. In group A patients underwent Dacryocystorhinostomy under local anesthesia using Bupivacaine and the commercially available xylocaine with 1:200,000 adrenaline while patients in the group B underwent surgery using Bupivacaine, Xylocaine with 1:50,000 adrenaline. Per-operative pain, bleeding and effectiveness of anesthesia were measured on a numeric scale. Means of pain score, bleeding score and anesthesia effectiveness score were computed and were compared.
