An interventional study of ultrasound-guided femoral nerve block and Intravenous or intramuscular pain medication in Hip Fractures, sponsored by National Taiwan University Hospital. Recruiting at 1 site in Taiwan. Open to participants aged 20 Years and older. Per ClinicalTrials.gov, last updated 2025-08-05.
Sponsored by National Taiwan University Hospital · Not applicable, Interventional, and Treatment
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.
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.

Exclusion Criteria:
Patients with hip fractures had underwent Ultrasound-guided femoral nerve block performed by emergency physicians.
Procedure: ultrasound-guided femoral nerve block
Patients with hip fractures had given intravenous or intramuscular opioids or NSAID at the emergency department.
Drug: Intravenous or intramuscular pain medication
The local analgesia is injected and infiltrated around the femoral nerve under ultrasound guidance.
Intravenous or intramuscular pain medication is given for patients with hip fracture.
a short time of pain relief
The numerical pain score from 0 to 10 is used to assess pain severity and the scale 0 means no pain and the scale 10 means the worst pain imaginable. The pain score assessed for the leg with hip fracture at rest and with movement will be recorded after different pain medicine and the reduction of pain score at different time frame will be evaluated. The more reduction of pain score, the better.
Time frame: 2 hours
Adverse effects
Any adverse effects of different pain medication
Time frame: two hours
Patient satisfaction
The difference of patient satisfaction between ultrasound-guided femoral nerve block and the liberal use of pain medication
Time frame: two hours
Complications of ultrasound-guided femoral nerve block
Any complications of ultrasound-guided femoral nerve block
Time frame: two hours and one week after ultrasound-guided femoral nerve block or after hospital discharge
