Summary

This is a dose finding study to identify the minimum effective anesthetic concentration (MEAC) of ropivacaine to produce insensate body parts sufficient for surgery in supraclavicular and infraclavicular approaches to the brachial plexus, parasacral and popliteal approaches to the sciatic nerve, femoral nerve and transversus abdominis plane (TAP) blocks in adults.

Conditions

• Surgical Anesthesia

Interventions

Type	Name	Description
