Trial summary
Hip Fracture (HFx) is a painful injury that is often treated in the Emergency Department (ED) with intravenous opiates. However, this class of medications may cause deleterious side effects. An alternative analgesic approach involves regional anesthesia. Read more about this study

About this study
Official title: Ultrasound Guided Femoral (3 in 1) Nerve Block Versus Ultrasound Guided Fascia Iliacus Compartment Block Versus Standard Treatment for Pain Control in Patients With Hip Fractures in the Emergency Department
Hip Fracture (HFx) is a painful injury that is often treated in the Emergency Department (ED) with intravenous opiates. However, this class of medications may cause deleterious side effects. An alternative analgesic approach involves regional anesthesia. The investigators attempted to determine (1) whether ultrasound guided peripheral nerve blocks (UPNBs) could be safely performed in an ED setting, (2) whether UPNBs would be more effective than standard treatment in controlling pain from HFx and (3) which of two UPNBs was superior for pain relief.
A convenience sample of patients with an isolated HFx and a pain score > 5/10 were enrolled and randomized to one of three arms: (1) Ultrasound guided 3-in-1 femoral nerve block (UFNB), (2) Ultrasound guided fascia iliaca compartment block (UFIB), or (3) IVMS. Patients indicated their pain from 0 (no pain) to 10 (extreme pain).
Read the detailed description
Hip fracture (HFx) is a painful orthopedic emergency that commonly presents to the Emergency Department (ED). There are approximately 320,000 HFx diagnosed annually in the United States, with this number expected to increase as the population ages. It has previously been shown that patients with pain from HFx are undermedicated while in the ED, particularly in overcrowded facilities. Current treatment for ED patients who are experiencing pain from acute HFx is often with intravenous morphine sulfate (IVMS). Morphine can have many undesirable side effects, but of particular concern are delirium, hypotension and respiratory depression. These complications may be accentuated in elderly patients and may necessitate increased patient monitoring and greater utilization of limited ED resources.An alternative to systemic opioid analgesia involves peripheral nerve blockade. Anesthesiologists frequently perform nerve blocks in the peri-operative and post-operative period to control pain in patients undergoing hip surgery. Traditionally, nerve stimulators were used to place the nerve block. However, ultrasonography is being used with increasing frequency to facilitate placement of these peripheral nerve blocks. As Emergency Physicians (EP) become more facile with the use of bedside sonography, ultrasound guided peripheral nerve blockade for HFx may be ideally suited for the ED environment, where one injection could control pain for many hours. The 3-in-1 femoral nerve block (FNB), in which anesthetic is injected adjacent to the femoral nerve but also affects the lateral femoral cutaneous and the obturator nerves, has been shown to be as effective as morphine for pain control of HFx in the ED. Sonographic guidance has been shown to increase the success rate of this block, decrease the time to analgesia, decrease the amount of local anesthetic needed to achieve adequate regional anesthesia, and decrease the incidence of inadvertent intravascular injection.
To date, there has been limited research describing the utilization of ultrasound guided femoral nerve blocks in an ED setting. Beaudoin et al. performed a feasibility study demonstrating that EP could effectively perform ultrasound guided femoral nerve blocks. Reid et al. found a significantly decreased time to complete analgesia when using sonographic guidance compared to an anatomic landmark technique. In this later study, anesthesia was assessed by checking skin sensation. Neither of these studies utilized a 3-in-1 nerve block, which may provide greater pain relief for patients with HFx.
The fascia iliaca compartment block (FIB) is also effective for treating pain due to HFx. It has been shown in the pediatric anesthesia and pediatric emergency medicine literature that it provides adequate analgesia, and may provide more effective analgesia than the FNB for femur fractures in children. Most of the studies describe the FIB being performed using a technique based on anatomic landmarks. One recent study described ultrasound guidance of the FIB (UFIB) increasing the efficacy of the sensory blockade (12). UFIB has not previously been studied in the ED setting.
We attempted to determine (1) whether ultrasound guided peripheral nerve blocks (UPNB) could be safely performed in an ED setting, (2) whether UPNB would be more effective than standard treatment in controlling pain from HFx in which a 2.5 unit decrease in pain scores was considered clinically significant, and (3) which of two UPNB was superior for pain relief.

| Study group | Role | What they receive |
|---|---|---|
| UFNB | Experimental | Ultrasound guided 3 in 1 femoral nerve block: The UFNB was performed by first visualizing the femoral nerve in a transverse orientation just inferior to the inguinal ligament and lateral to the common femoral artery. Receives: Procedure: UFNB (Ultrasound guided femoral nerve block) |
| UFIB | Experimental | Ultrasound Guided Fascia Iliaca Compartment Block: For the UFIB, the two fascial planes, the fascia lata and the fascia iliaca, were sonographically visualized with the probe transverse to the thigh just inferior to the inguinal ligament and one-third of the distance from the anterior superior iliac spine to the pubic tubercle. Receives: Procedure: UFIB (Ultrasound Guided Fascia Iliaca Compartment Block) |
| IVMS | Active comparator | IV Morphine: IV Morphine patients were also monitored for a minimum of one hour after they were given a second dose of IV morphine, 0.1 mg/kg, once the radiographs demonstrated fracture. The control group was also eligible to receive rescue analgesia of an additional 0.1 mg/kg of IV morphine, followed by repeat doses of 0.05 mg/kg Receives: Drug: IVMS (IV Morphine) |

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing UFNB (Ultrasound guided femoral nerve block), UFIB (Ultrasound Guided Fascia Iliaca Compartment Block) and IVMS (IV Morphine) in people with Hip Fracture, run by Antonios Likourezos at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 24 Apr 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain Score at 30 Minutes (time frame: 30 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01904071, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jun 2018.
