Large study to count hidden dangers of nerve blocks
NCT ID NCT07238933
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
This observational study will follow about 3,400 adults receiving single-shot regional anesthesia (nerve blocks) for surgery. Researchers aim to measure how often complications like nerve injury, bleeding, or lung puncture occur. The study does not test any new drug or treatment—it simply collects real-world data to better understand risks.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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.
