Ophthalmic regional blockade complication rate: A single center audit of 33,363 ophthalmic operations

摘要

Study Objective: To determine the incidence and contributing factors of complications for patients receiving regional ophthalmic anesthesia. Design: Retrospective analysis. Setting: Tertiary-care eye center. Measurements: Anesthesia records of ophthalmic blocks performed from January 2003 to June 2009 were reviewed. The frequency of block-related complications and details of each complication were recorded. Main Results: A total of 33,363 peribulbar blocks were performed, with a total incidence of 0.12% (41 cases). These complications may be divided into systemic complications, 18 cases (0.053%) and needle-related complications, 23 cases (0.068%). Conclusion: Peribulbar block complications were rare. In this series, experience of caregivers and axial and needle length were not contributing factors.
