Trial summary

Ultrasound-guided femoral nerve block is a common regional anesthesia technique. The optimal method of needle guidance (in-plane versus out-of-plane) with regards to the block efficacy and avoidance of needle-nerve contact has not been established. Read more about this study

About this study

Official title: Incidence of Intraneural Needle Insertion in Ultrasound Guided Femoral Block: Out of Plane Versus in Plane Approach

Ultrasound-guided femoral nerve block is a common regional anesthesia technique. The optimal method of needle guidance (in-plane versus out-of-plane) with regards to the block efficacy and avoidance of needle-nerve contact has not been established. In this study the investigators tests the hypothesis that the incidence of needle-nerve contact is higher with the needle insertion in an out-of-plane than with the in-plane approach.

Read the detailed description

Fourty-four patients with hip fracture (American Society of Anesthesiologists physical status 1-3) are being randomized to receive the femoral block with an out-of-plane (needle inserted at a 45°-60° angle 1 cm caudal to the midpoint of the ultrasound probe just above the femoral nerve) or an in-plane technique (needle inserted 0.5 cm from the side of the probe lateral to the femoral nerve). The data collected includes the depth of needle insertion at the endpoint before injection, response to nerve stimulation, distribution of the injected volume in relation to the nerve (anterior vs posterior, the latter indicating impalement), block efficacy at 20 minutes and 24 hours, and any signs of nerve injury).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of intraneural needle insertion in ultrasound-guided femoral block: out-of-plane versus in-plane approach

    The incidence of needle-nerve contact is higher with the out-of-plane approach (inserting the needle into the fascia at the midpoint over the femoral nerve)needle-nerve contact than with the in-plane approach (inserting the needle lateral to the femoral nerve).

    Measured: 4 months

Secondary outcomes (1)
  1. Number of Participants with femoral block success in ultrasound-guided femoral block: out-of-plane versus in-plane approach.

    The efficacy of the out-of-plane approach (inserting the needle into the fascia at the midpoint over the femoral nerve)needle-nerve contact and the in-plane approach (inserting the needle lateral to the femoral nerve).

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A study testing Needle placement in people with Peripheral Nerve Injury, run by Hospital Clinic of Barcelona at 2 sites in 2 countries.

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 3 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 15 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, Spain. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ana Ruiz, MD (0034932275558, anaruiz@clinic.ub.es), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of intraneural needle insertion in ultrasound-guided femoral block: out-of-plane versus in-plane approach (time frame: 4 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 15 Mar 2012.
