About the research
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 change in movement-evoked pain score from baseline to 30 minutes. The secondary outcome is patient satisfaction and adverse effects for different method of pain control.
Read the 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.
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
Inclusion Criteria:
- Patients older than 20-year-old with hip fractures
- Stay in the emergency department for at lease two hours
Exclusion Criteria:
- hemodynamic unstable
- major trauma in addition to hip fractures
- the use of any pain management before the arrival of emergency department
- inability to understood the numerical rating scale after instruction
- allergy to local anesthetics
- coagulopathy
- injection site infection
Treatment, groups and participation
The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

Ultrasound-guided femoral nerve block
Patients with hip fractures had underwent Ultrasound-guided femoral nerve block performed by emergency physicians.
Procedure: ultrasound-guided femoral nerve block
The liberal use of pain medication
Patients with hip fractures had given intravenous or intramuscular opioids or NSAID at the emergency department.
Drug: Intravenous or intramuscular pain medication
ultrasound-guided femoral nerve block PROCEDURE
The local analgesia is injected and infiltrated around the femoral nerve under ultrasound guidance.
Intravenous or intramuscular pain medication DRUG
Intravenous or intramuscular pain medication is given for patients with hip fracture.
What researchers are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
Change in movement-evoked pain score from baseline to 30 minutes
Time frame: Baseline and 30 minutes after analgesia
Pain during movement of the affected leg is rated on an 11-point numerical rating scale (NRS; 0 = no pain, 10 = worst pain imaginable) before analgesia (baseline) and 30 minutes after analgesia. The change from baseline is compared between the femoral nerve block group and the intravenous or intramuscular pain medication group.
Secondary measures
Adverse effects
Time frame: two hours
Any adverse effects of different pain medication
Patient satisfaction
Time frame: two hours
The difference of patient satisfaction between ultrasound-guided femoral nerve block and the liberal use of pain medication
Complications of ultrasound-guided femoral nerve block
Time frame: two hours and one week after ultrasound-guided femoral nerve block or after hospital discharge
Any complications of ultrasound-guided femoral nerve block
Change in pain score at rest and with movement
Time frame: Baseline and 30, 60, and 120 minutes after analgesia
Pain at rest and during movement of the affected leg is rated on an 11-point numerical rating scale (NRS; 0 = no pain, 10 = worst pain imaginable). The change from baseline at each time point is compared between groups.
