What participants receive

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

  • TMQLB group 1Procedure or surgery

    The patient is placed in the lateral position. The curved (C1-5) probe of Philip CX50 Ultrasound Scanner is used for scan and located vertical to the iliac crest at the posterior axillary line to find the Shamrock sign. The 22-G needle is then inserted in plane and directed to the QL muscle. After the proper position of the needle tip between the psoas major muscle and the quadratus lumborum muscle is confirmed, 0. 4 ml/kg 0.5% ropivacaine with 1: 200,000 adrenaline is injected into the interfascial plane.

    Followed by IPCA in the first 48h after surgery: morphine boluses: 1.5-2 mg, lockout time :10 min, 1h limitation: 6-8 mg morphine.

  • TMQLB group 2Procedure or surgery

    The patient is placed in the lateral position. The curved (C1-5) probe of Philip CX50 Ultrasound Scanner is used for scan and located vertical to the iliac crest at the posterior axillary line to find the Shamrock sign. The 22-G needle is then inserted in plane and directed to the QL muscle. After the proper position of the needle tip between the psoas major muscle and the quadratus lumborum muscle is confirmed, 0. 6 ml/kg 0.5% ropivacaine with 1: 200,000 adrenaline is injected into the interfascial plane.

    Followed by IPCA in the first 48h after surgery: morphine boluses: 1.5-2 mg, lockout time :10 min, 1h limitation: 6-8 mg morphine.

  • TPVBProcedure or surgery

    The patient is placed in the lateral position, the spinous processes of T10 are identified and marks are made 2cm lateral to the spinous processes. The linear(L12-3) probe of Philips CX50 is placed transversally at the mark to identify the paravertebral space. Then a 22-G needle is inserted in-plane from lateral to medial and advanced until the tip reached the paravertebral space surrounded by the parietal pleura and the superior costotransverse ligament. 0.4 ml/kg 0.5% ropivacaine with 1: 200,000 adrenaline is injected into the paravertebral space of T10.

    Followed by IPCA in the first 48h after surgery: morphine boluses: 1.5-2 mg, lockout time :10 min, 1h limitation: 6-8 mg morphine.

What is being measured

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

  1. mean VAS of the first postoperative 24 hours

    VAS is an internationally recognized pain scale with 11 points ranging from 0 to 10 points, with 0 defined as no pain and 10 defined as the worst pain imaginable. The VAS will be registered at 0, 2, 4, 8, 12, 24 hours after the surgery, and the primary outcome will be calculated as the mean VAS scores measured at these time point.

    Measured: within the first 24 postoperative hours

Secondary outcomes (10)
  1. cumulative morphine consumption

    morphine consumption will be registered at 0, 2, 4, 8, 12, 24, 48, 72 hours and 7 days after the surgery and will be calculated as the sum of the values

    Measured: at 0, 2,4, 8, 12, 24 ,48, 72hours and 7 day after the surgery

  2. long-term pain control

    evaluated by VAS at 48, 72 hours and 7 days after the surgery

    Measured: at 48, 72 and 7 days after the surgery

  3. dermatomal distribution of sensory loss

    evaluated at 10, 20, 30 and 40 minutes after the intervention with pinprick test using Von Frey filaments

    Measured: 10, 20, 30 and 40 minutes after the intervention

  4. nausea score

    Measured: at 0, 2, 4, 8, 12, 24 and 48 hours after the surgery;

  5. pruritus score

    Measured: at 0, 2, 4, 8, 12, 24 and 48 hours after the surgery;

  6. ambulation time

    time to patient's first walking after the surgery

    Measured: after the surgery

  7. time of recovery of bowel movement

    defined as the time to first flatus

    Measured: after the surgery

  8. quality of recovery evaluated by the self-assessment 15-item quality of recovery (QoR) scale

    QoR is a 15-item questionnaire which will score on a scale of 0-10 pertaining to patient's comfort, support system, pain, well-being, and ability to carry out daily activities, where 0 indicates none of the time and 10 indicates all of the time

    Measured: at 3 days and 5 days after the sugery

  9. postoperative length of hospital stay

    time to patient's discharge

    Measured: after the surgery

  10. patient satisfaction with anesthesia

    evaluated with the Chinese version of Bauer questionnaire at 48 hours after the surgery

    Measured: at 48 hours after the surgery

Questions about this trial

What is this clinical trial studying?

A study testing TMQLB group 1, TMQLB group 2 and TPVB in people with Nerve Block, Nephrectomy, Analgesia, run by Cui Xulei at 1 site in China.

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 5 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: stopped early, as of the sponsor's last update on 20 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

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?

mean VAS of the first postoperative 24 hours (time frame: within the first 24 postoperative hours). 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 NCT03414281, 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 20 Mar 2020.
