Comparison of Severity of Pain With and Without Sedation in Patients Undergoing External Dacryocystorhinostomy under Local Anesthesia

Aim: To compare of severity of pain with and without sedation in patients undergoing external dacryocystorhinostomy under local anesthesia. Methodology: A total of 240 patients of both gender having chronic dacryocystitis between age 20 and 60 years were included. Patients with gross nasal pathology, previous dacryocystorhinostomy and lower lid laxity were excluded. Then selected cases were placed randomly into two groups i.e. Group A (with sedation) & Group B (without sedation), by using lottery method. In all patients external dacryocystorhinostomy was performed by injecting local anesthetic (lignocain 2%) locally at the site of surgery (lacrimal sac area). At the end of surgery, numerical pain rating scale was used to assess the grading of severity of pain. Results: The average age in group A was 43.65 ± 11.65years and in group B was 44.40 ± 10.5years.In group A (with sedation), 89 (74.17%) patients found with mild pain, 20 (16.67%) found with moderate pain and 11 (9.17%) found with severe pain, while in group B (without sedation), 51 (42.5%) patients found with mild pain, 40 (33.33%) found with moderate pain and 29 (24.17%) found with severe pain. Significant difference for severities of pain between the both groups was found. Conclusion: This studyconcluded that external dacryocystorhinostomy under local anesthesia with sedation is more effective and associated with less pain compared to dacryocystorhinostomy under local anesthesia without sedation.
