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

DRUG

Ropivacaine concentration

Single shot preoperative perineural injection of ropivacaine to achieve surgical anesthesia. The concentration of ropivacaine is lowered by 0.05% after every successful surgical anesthesia specific to that block and raised by 0.05% after every unsuccessful surgical anesthesia specific to that block
