About

A revised ultrasound-guided approach to the lumbar plexus is investigated as for efficacy and safety in elderly trauma patients undergoing operations of the lower extremeties.

Full description

A modified ultrasound-guided Shamrock approach combined to nerve stimulation of the lumbar plexus is going to be investigated, in elderly trauma patients undergoing procedures of the lower extremities. The technique is going to be assessed as for its safety and its accuracy in localization of the plexus, by multiple measurements of the imaging time and needling time, In addition, efficacy and complications will be recorded and assessed during the immediate postoperative period.
