About this study

Official title: Dislocation Rates of Femoral Catheter Placed Sonographically Either In-plane or Out-of-plane: A Prospective Randomized Study

Dislocation of the femoral nerve catheters, which are used as postoperative analgesic method after knie surgery, will be studied. Two Groups will be compared; in the first group the femoral nerve catheter will be placed sonographically with the in-plane technique, whereas in the other Group the femoral nerve catheter will be placed sonographically with the out-of-plane technique

Read the detailed description

Patients scheduled for elective major knee surgery will be assessed for eligibility and after written informed consent included in this clinical trial. Prior to surgery, the patient will receive a femoral catheter with either ultrasound placed in-plane (IP) or with ultrasound placed out-of-plane (OOP) as perioperative analgesic regimen using well-established and previously published techniques. The allocation to the different groups will be according to a computerized random-list established the day prior to surgery. In all cases, continuous regional anaesthesia regimen will be started after surgery. For surgery the patient can receive spinal anaesthesia, or a general anaesthesia. The use of a sciatic block will be applied according to the clinical standards of our department. Ropivacaine 0.3% (bag with 100 ml, Sintetica SA, Mendrisio Switzerland) 20 ml for the femoral catheter insertion. In both groups 10ml of ropivacaine 0.3% will be applied over the needle and 10ml over the catheter after its placement. In both groups the catheters will be connected to the electronic pump in the recovery room and run with ropivacaine 0.3% at 6 ml/h with boli of 4ml every 20min.

First rescue medication: ropivacaine 0.3% 20ml up to 3 x day. The catheters will stay in place for 48 hours and removed only if VAS< 40 with standard analgesia.

At 24 and 48 hours after placement of the femoral catheter, a bolus of NaCl 0.9% 10ml will be applied under ultrasound control in both groups and dislocation will be noted if the local anaesthetic does not reach the femoral nerve. In that case it will be noted where the local anaesthetic is localised. Block quality will be checked by applying cold on the front of the knee and measuring the sensation to cold in a scale from 0 to 2 (before NaCl 0.9% application). Pain will be assessed before the dislocation test only for in front and medial side of the knee in a regularly used NRS scale from 0 to 10. Complications and side effects of regional anesthesia in both groups will be documented (toxicity, blood in catheter, infection).

What is being measured

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

  1. Dislocation of the femoral nerve catheter at 48 hours after its placement.

    The catheter will be checked if in the right place using ultrasound location

    Measured: 48 hours after the placement of the catheter

Secondary outcomes (7)
  1. Time to place the catheter

    Time to place the catheter measured in seconds

    Measured: 30min (time needed to place and fix a femoral catheter)

  2. satisfaction of the patient

    satisfaction of the Patient during the block procedure in a scale of 0 to 10 (0 being not satisfied at all and 10 being totally satisfied)

    Measured: 48 hours after the placement of the catheter

  3. number of failed blocks

    number of failed blocks needed to be repeated

    Measured: 30min (time needed to place and fix a femoral catheter and regognize if it works)

  4. difficulty placing the catheter

    difficulty placing the catheter under ultrasound control

    Measured: 30min (time needed to place and fix a femoral catheter and to decide if it was difficult)

  5. Effect of the femoral catheter on the sensory sensation

    cold (cold metal bar) and pinprick (atraumatic test, using a sharp tip): can the patient recognize cold and sharp during the femoral nerve block? Answers are yes or no.

    Measured: at 24 hours and 48 hours after the femoral nerve catheter

  6. rescue boli given over the catheter in the 48 hours after its placement

    amount of local anaesthetic rescue boli given

    Measured: At 48 hours after the placement of the catheter

  7. Dislocation of the femoral nerve catheter at 24 hours after its placement.

    amount of catheter dislocations

    Measured: At 24 and at 48 hours after the placement of the catheter

Questions about this trial

What is this clinical trial studying?

A study testing In-plane Group and Out-of-plane Group in people with Catheter Complications, run by Jose Aguirre at 1 site in Switzerland.

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 12 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 21 Jun 2019. 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 Switzerland. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Dislocation of the femoral nerve catheter at 48 hours after its placement. (time frame: 48 hours after the placement of the catheter). 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 NCT03693755, which also lists 1 linked publication.

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 21 Jun 2019.
