NCT05191966

Brief Summary

In this study, it was aimed to evaluate the effects of subcostal anterior quadratus lumborum block (S-QLB3) and thoracic paravertebral block (TPVB) on postoperative acute pain scores and opioid consumption in the first 24 hours after laparoscopic nephrectomy surgery.

Outcome Measures

Primary Outcomes (1)

  • Morphine consumption in the first 24 hours after surgery

    Morphine consumption in the first 24 hours will be measured. Patients will be able to request opioids via a PCA device when their NRS score is above 3 at rest and during activity (coughing and deep breathing).

    Postoperative Day 1

Secondary Outcomes (1)

  • Post-operative acute pain

    Postoperative Day 1

Other Outcomes (8)

  • Patients' satisfaction and quality of pain management

    Postoperative Day 1

  • The number of patient required antiemetic

    Postoperative Day 1

  • Remifentanil consumption during the surgery

    The remifentanil consumption will be recorded from anesthesia induction until the patient is referred to the recovery unit, up to 240 min

  • +5 more other outcomes

Study Arms (2)

Group S-QLB3

ACTIVE COMPARATOR

S-QLB3 block (0.4 ml/kg of 0.25% bupivacaine + 1:400.000 adrenaline) + iv morphine-PCA

Procedure: Subcostal Anterior Quadratus Lumborum Block

Group TPVB

ACTIVE COMPARATOR

TPVB block (0.4 ml/kg of 0.25% bupivacaine + 1:400.000 adrenaline) + iv morphine-PCA

Procedure: Thoracic Paravertebral Block

Interventions

S-QLB3 block will be performed 30 min. before general anesthesia. For anterior QL block via subcostal approach, 0.4 ml/kg of 0.25% bupivacaine + 1:400.000 adrenaline will be injected into the interfacial plane between the QLM and PMM. IV-PCA: The requested dose will be 20µg/kg morphine, the lock-in time will be 6-10 minutes, the 4-hour limit will be 80% of the total calculated dose.

Also known as: S-QLB3
Group S-QLB3

TPVB block will be performed 30 min. before general anesthesia. TPVB will be performed at T10 transverse process level, 0.4 ml/kg of 0.25% bupivacaine + 1:400.000 adrenaline will be injected into the paravertebral space. IV-PCA: The requested dose will be 20µg/kg morphine, the lock-in time will be 6-10 minutes, the 4-hour limit will be 80% of the total calculated dose.

Masking Details
Sealed opaque envelopes containing study participation numbers will be used to assign each patient. A researcher not involved in patient follow-up will use the web-based "Research Randomizer" (Urbaniak and Plous 2013) tool to give each participation number to a random group with a 1:1 ratio. A nurse not an active investigator in the study will have each participant choose an envelope containing the study participation number. They will inform the anesthetist who will administer the block/blocks about which group the patient is in immediately before administration. Researchers, patients, surgeons, and nurses will not be aware of the randomization of groups.
Purpose
SUPPORTIVE CARE
Intervention Model
PARALLEL
Model Details: A block randomization list will be created by a doctor who does not participate in patient follow-up using a web-based program, 'Research Randomizer (Urbaniak and Plous 2013)'.
