Hemodynamic and Clinical Outcomes of Local Anesthetic Use in Patients Undergoing External Dacryocystorhinostomy

BACKGROUND: The aim of this study is to evaluate the effect of using local anesthesia at the incision area during external dacryocystorhinostomy (E-DCR) to control intraoperative hemorrhage on hemodynamic and clinical outcomes. METHODS: All patients aged 18 years and older who underwent external dacryocystorhinostomy at Niğde Training and Research Hospital between January 2024 and March 2025 with a diagnosis of primary acquired nasolacrimal duct obstruction were included in the study. Patients included in the study were randomly divided into 2 groups: those who used local anesthesia (20 mg/mL lidocaine hydrochloride and 0.0125 mg/mL epinephrine, 3 mL) at the incision site during surgery (group 1) and those who did not (group 2). Hemodynamic parameters were measured at three different time points: before osteotomy, during osteotomy, and after osteotomy. Postoperative pain was assessed using the visual analog scale (VAS) score at 0, 2, 6, and 12 hours postoperatively. RESULTS: A total of 39 patients were included in the study. While the average intraoperative hemorrhage was 4.2±1.0 mL in group 1, 6.6±1.2 mL in group 2. This difference observed between the groups was statistically significant ( P
