简要总结
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.
详细描述
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.

结局指标
主要结局
Time required to localize the lumbar plexus
时间窗: 10 minutes (from the begining of imaging procedure) (time in seconds to localize the plexus)
The time (in secondes) required of this modified Shamrock method to localize the lumbar plexus in the interpsoas compartment in elderly-trauma patients undergoing orthopedic procedures of the lower extremeties. Imaging time will be calculated (time to obtain appropriate imaging of the plexus) as well as needling time (time to obtain appropriate needle placement on the plexus)
Complications from lumbar plexus blockade
时间窗: 1 month
Safety of the modified Shamrock method of lumbar plexus blockade in elderly-trauma patients undergoing orthopedic procedures of the lower extremeties. All possible complications will be recorded (i.e. neurological complications, numbness, mobility disorder, haemmorhage, haematoma, e.t.c.)
次要结局
- Postoperative pain(4 hours (visual analogue scale 0-10 at 4 hours postoperatively))
