About

In this prospective study, emergency physicians perform ultrasound-guided femoral nerve block for patients with hip fractures. We compare the effectiveness of analgesia and patient satisfaction of ultrasound-guided femoral nerve block with liberal use of the pain medicine in the emergency department. The primary outcome is the assessment of time to relief the pain with fewer adverse effects and less rescue pain medication use. The secondary outcome is patient satisfaction and adverse effects for different method of pain control.

Full description

The aim of this study is to compare the effectiveness of ultrasound-guided femoral nerve blocks performed by emergency physicians for pain control in the emergency department with traditional pain medicine.

This study is a prospective before-and-after design. The enrollees are 20-year-old and older adult patients with hip fractures. We use numerical rating scale using a 0-10 scale to assess pain severity at the different time frame after giving pain medicine. The scale zero means "no pain" and scale 10 means "the worst pain imaginable".

The primary outcome is assessed by the reduction of pain scale which are taken on a numeric rating scale every 30 minutes before and after pain management. The secondary outcome compares complications, adverse effects and patient satisfaction for different method of pain control.
