Blood Pressure Variations in Patients Undergoing Phacoemulsification Surgery via Topical and Peribulbar Anaesthesia

Abstract: Purpose: To compare blood pressure changes in patients undergoing phacoemulsification surgery using either topical or peribulbar anesthesia. Methods: In this prospective study, patients were divided equally into two groups: one received topical anesthesia with proparacaine drops, and the other received peribulbar anesthesia using lignocaine and bupivacaine. Blood pressure readings-systolic (SBP), diastolic (DBP), and mean (MBP)-were recorded before, during, and after surgery. Results: There were no significant age or gender differences between groups. In the topical group, both SBP and MBP rose significantly during surgery, while DBP remained unchanged. In contrast, only SBP increased slightly in the peribulbar group. Intraoperatively, the topical group showed significantly higher SBP (152.21 vs. 135.11 mmHg) and MBP (107.00 vs. 99.63 mmHg) compared to the peribulbar group. No significant differences were found pre- or postoperatively. Conclusion: Topical anesthesia during phacoemulsification is associated with higher intraoperative blood pressure, suggesting the need for closer monitoring to manage potential hemodynamic changes.
