Neurological Events and Unforeseen Risks After Locoregional-anesthesia

This is a multicenter, prospective, observational study aimed at determining the incidence of neurological and non-neurological complications following locoregional anesthesia procedures. The study will collect data on events such as nerve injury, hematoma, pneumothorax, and local anesthetic systemic toxicity.

Inclusion Criteria: * Age ≥ 18 years. * Scheduled to undergo a single-shot nerve or fascial plane block. * Ability to provide written informed consent. Exclusion Criteria: * Performance of more than one single-shot nerve or fascial plane block within the same anatomical region or sensory distribution during the same procedure. * Use of continuous nerve or fascial plane catheter-based anesthesia. * Presence of a language barrier that, in the investigator's judgment, would prevent adequate follow-up.
