About this study

This study aims to assess if Quadratus Lumborum (QL) blocks are non-inferior to epidural analgesia for pain control and opioid consumption through the third postoperative day in patients having open partial nephrectomy. Patients satisfying all inclusion and exclusion criteria will be randomized in a 1:1 ratio to either epidural catheter or QL catheter.

Read the detailed description

QL blocks with a single shot and catheters infusions may be an alternative to epidural analgesia. However, the relative efficacy, safety, and cost of the two approaches remain unclear.

Epidural analgesia is frequently used as a component of multimodal analgesia for thoracic and abdominal surgery. QL block has been introduced recently as a component of multimodal analgesia for lower thoracic and abdominal surgery. In general, insertion of QL catheter is easier and safer than insertion of epidural catheters. QL catheter management is also less complicated than epidural analgesia (fewer catheter displacements and less hemodynamic compromise) and decreases the level of complexity in postoperative care. Our hypothesis is that the subcostal QL approach with a continuous catheter is non-inferior to epidural analgesia for pain control and opioid consumption in patients having open partial nephrectomy procedure.

Being tested
Quadratus lumborum block, Epidural analgesia

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Quadratus lumborum blockProcedure or surgery

    Quadratus lumborum (QL) block for open partial nephrectomy.

  • Epidural analgesiaProcedure or surgery

    Epidural analgesia for open partial nephrectomy.

Study groups in NCT03110081
Study groupRoleWhat they receive
Quadratus lumborum blockExperimentalQuadratus lumborum (QL) block group will receive a single shot injection of 25 ml 0.25% bupivacaine pre-operatively, followed post-operatively by infusion of ropivacaine 0.2% continuously administered via the QL catheter for at least 48 hours.
Receives: Procedure: Quadratus lumborum block
Epidural analgesiaActive comparatorMidthoracic catheters will be inserted preoperatively. A bupivacaine 0.1% infusion will be started before the surgical incision, and continuously administered for at least 48 hr at an infusion rate of 5 ml/hr.
Receives: Procedure: Epidural analgesia

What is being measured

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

  1. Total opioid consumption

    Total IV morphine-equivalent doses used, started postoperatively at the time of arrival to post anesthesia care unit until 72 hours after surgery.

    Measured: Arrival to post anesthesia care unit until 72 hours after surgery

  2. Postoperative pain

    Time-weighted average verbal rating scale for pain until 72 hours after operation as a time-weighted average, based on nursing assessments at four-hour intervals. The verbal rating scale ranges from 0 to 10, with 0 indicating no pain and 10 indicating worst pain imaginable. Time-weighted average pain is defined as the sum of each time interval between two adjacent pain score measurements multiplied by the average of the two corresponding pain scores divided by the time interval between the first and last pain scores.

    Measured: Arrival to post anesthesia care unit until 72 hours after surgery

Secondary outcomes (4)
  1. Patient Global Assessment

    Patient global assessment of pain control is measured on an ordinal scale by the patient. Patients can rate their pain control as poor, fair, good, or excellent.

    Measured: Three days after surgery

  2. Doses of antiemetic medications administered

    Count of the number of antiemetic medications administered.

    Measured: Arrival to post anesthesia care unit until the third day after surgery

  3. Duration of postoperative hospitalization

    Duration of postoperative hospitalization

    Measured: From the date of surgery to hospital discharge, assessed up to 12 months.

  4. Episodes of hypotension

    Number of episodes of hypotension during hospital stay, defined by MAP less than 65 mmHg requiring intervention.

    Measured: Arrival to post anesthesia care unit until the third day after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Quadratus lumborum block and Epidural analgesia in people with Open Nephrectomy Surgery, run by The Cleveland Clinic 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 1 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: finished, as of the sponsor's last update on 29 Apr 2021. 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.

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?

Total opioid consumption (time frame: Arrival to post anesthesia care unit until 72 hours after surgery). The study lists 2 primary outcomes in all. 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 NCT03110081, 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 29 Apr 2021.
