About this study

Official title: Transmuscular Quadratus Lumborum Block Versus Thoracic Paravertebral Block for Acute Pain and Quality of Recovery After Laparoscopic Partial Nephrectomy

This trial is a prospective, randomized, single-center, open-label, parallel-arm, blinded-analysis trial, the objective of which is to evaluate the effect of transmuscular quadratus lumborum block (TMQLB) in the pain relief and quality of recovery in laparoscopic partial nephrectomy compared with thoracic paravertebral block (TPVB).

Being tested
preoperative single-shot TMQLB, preoperative single-shot TPVB, patient controlled intravenous analgesia(PCIA)
Medical subject headings
Agnosia

What participants receive

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

  • preoperative single-shot TMQLBProcedure or surgery

    The patient is placed in the lateral position. The curved probe of 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 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.

  • preoperative single-shot 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 curve probe of ultrasound scanner 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 is injected into the paravertebral space of T10.

  • patient controlled intravenous analgesia(PCIA)Drug

    at the end of surgery, patient is administered a PCIA with 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. cumulative morphine consumption

    Measured: within 48 postoperative hours

Secondary outcomes (8)
  1. The pain scores determined by the numeric rating scale (NRS, 0-10)

    NRS 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.

    Measured: within 48 postoperative hours

  2. dermatomal distribution of sensory reduction

    Thirty minutes after the block, the bilateral dermatomal sensory blocks for the anterior abdomen (between the anterior axillary and mid-clavicular lines) and thigh were assessed with the pinprick method. A reduce in pinprick sensation relative to the unblocked side was interpreted as an effective block.

    Measured: 30 min after the block

  3. 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

  4. postoperative length of hospital stay

    time to patient's discharge

    Measured: within 2 weeks after the surgery

  5. patient satisfaction with anesthesia

    use the Chinese version Bauer questionnaire to assess the patient satisfaction with anesthesia

    Measured: 48 hours after surgery

  6. nausea and vomiting episodes

    Measured: within 24 hours after the surgery]

  7. ambulation time

    time from the end of the surgery to the first time to out-of-bed activity

    Measured: within the 5 days after surgery

  8. time of recovery of bowl movement

    Measured: within the 5 days after surgery

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.
