Quadratus Lumborum Block for Percutaneous Nephrostomy (QLB)

April 8, 2018 updated by: Ghada M N Bashandy, National Cancer Institute, Egypt

Quadratus Lumborum Block Versus Local Anesthetic Infiltration Combined With Monitored Anesthesia Care for Percutaneous Nephrostomy

Percutaneous nephrostomy (PCN) is one of the interventions in the radiology department in which pain control is necessary. Quadratus Lumborum (QL) block will be tried to limit the use of systemic analgesics and its accompanying untoward effects in those frail patients requiring PCN that is performed in the prone position.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Quadratus Lumborum block is a novel technique in which extension into the thoracic paravertebral space may occur. QL block would seem to be able to alleviate both somatic and visceral pain so it's expected to decrease the need for systemic sedation\analgesia to a minimum.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Active Comparator: Local Anesthetic infiltration and MAC
  • Local Anesthetic infiltration with 1% lignocaine
  • MAC with IV Midazolam Img\ml and Fentanyl 10 mic\ml
Procedure: Local Anesthetic infiltration
Lignocaine infiltration through the nephrostomy track
Other Names:
  • Lignocaine
Drug: MAC
Incremental doses are given to the targed sedation and analgesia
Other Names:
  • -Midazolam: 1 mg\ml
  • -Fentanyl: 10 mic\ml
Experimental: Quadratus Lumborum block and MAC
  • QL block with 0.25% levobupivacaine (Chirocaine, Abbott, Ireland) and 1% lignocaine
  • MAC with IV Midazolam Img\ml and Fentanyl 10 mic\ml
Drug: MAC
Incremental doses are given to the targed sedation and analgesia
Other Names:
  • -Midazolam: 1 mg\ml
  • -Fentanyl: 10 mic\ml
Procedure: Quadratus Lumborum block
A linear 12-MHz ultrasound probe will be placed in the anterior axillary line to visualize the typical triple abdominal layers. Then, the probe will be placed in the midaxillary line and at this point the layers of abdominal layers starte to taper. The probe will be placed in the posterior axillary line, sonoanatomy will show first the transversus abdominis disappearing then the internal oblique and external oblique forming aponeurosis and appearance of QL will be noticed. At the posterior border of the quadratus lumborum muscle and outside the fascia, Touhe needle will be inserted in plane and confirmed its position by injecting saline. Under ultrasound (US) guidance, local anesthetic mixure will be deposited separating the fascia
Other Names:
  • -0.25% levobupivacaine (Chirocaine, Abbott, Ireland)
  • -1% lignocaine

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Analgesia
Time Frame: 4 hours
Verbal Rating Scale is assessed for degree of pain during the procedure and after till discharge from the radiology department.
4 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
