Surgical Treatment of Hip Fractures Under Peripheral Regional Anesthesia

Helios Research Center80 enrolled

Overview

The study investigates whether treatment of proximal femoral fractures is possible using a peripheral regional anesthesia technique.

The study investigates whether treatment of proximal femoral fractures is possible using a peripheral regional anesthesia technique. After positioning on the non-fractured side, a double injection technique is used (dual guidance concept: nerve stimulation and sonography). The injections are performed parasacrally (blockade of the sacral plexus under the piriformis muscle) and lumbar paravertebrally (psoas compartment block and transmuscular quadratus lumborum block). Per block 20 ml ropivacaine 0.375% is administered (total dose: 225mg ropivacaine). The study examines the success rate (rate of successfully performed nerve blockade; need for supplemental medication: sufentanil and/or propofol; conversion rate to general anesthesia), circulatory stability (need for application of ephedrine or norepinephrine) and side effects.
