Midclavicle block: An anatomical study
Authors' conclusion
Our anatomical study demonstrates that the midclavicular block achieves effective distribution around the middle third of the clavicle, although complete circumferential anaesthesia of the clavicular periosteum was not achieved.
Study context
- Population
- Fresh human cadavers
- Participants
