Multicenter Study Comparative StudyComplications associated with eye blocks and peripheral nerve blocks: an american society of anesthesiologists closed claims analysis.
Concern for block-related injury and liability has dissuaded many anesthesiologists from using regional anesthesia for eye and extremity surgery, despite many studies demonstrating the benefits of regional over general anesthesia. To determine injury patterns and liability associated with eye and peripheral nerve blocks, we re-examined the American Society of Anesthesiologists Closed Claims Database as part of the American Society of Regional Anesthesia and Pain Medicine's Practice Advisory on Neurologic Complications of Regional Anesthesia and Pain Medicine. ⋯ Performance of eye blocks by anesthesiologists significantly alters their liability profile, primarily related to permanent eye damage from block needle trauma. Though most peripheral nerve block claims are associated with temporary injuries, local anesthetic toxicity is a major cause of death or brain damage in these claims.
