About this study

The objective of this trial is to examine if regional anesthetic blockade of the anterior abdominal wall via the transversus abdominis plane is a safe and feasible method of providing analgesia for children undergoing gastric tube insertion.

Read the detailed description

Regional abdominal field blockade has been demonstrated to deliver effective analgesia for procedures involving the anterior abdominal wall and may represent a feasible, minimally invasive alternative to central neuraxial blockade for some procedures and surgery of the abdomen.

Regional anesthesia and analgesia techniques are commonly advocated for post-operative pain control in pediatric surgical practice. Regional techniques decrease morphine requirements and improve the quality of post-operative pain control and patient-parent satisfaction. The most commonly used technique is caudal anesthesia, which is generally indicated for urologic surgery, inguinal hernia repair and lower extremity surgery. Complications are rare and usually minor, however, the caudal technique is limited in its ability to provide reliable analgesia to the abdominal wall and for surgical procedures involving the mid and upper abdomen. A reasonable alternative for these surgical procedures is to perform a formal lumbar epidural. This provides excellent post-operative analgesia and complications are rare. However, when complications do occur they are not minor. Because of the risks and potential complications of epidural catheter insertion, current clinical experience reveals an unwillingness for parents to consent to this technique.

On average, two hundred gastric tube insertions are performed in Image Guided Therapy (IGT) per annum (year) in this institution. Current standard practice for post-procedure pain control is local infiltration of the insertion site with local anesthetic during the procedure and intravenous morphine supplemented by rectal acetaminophen post-operatively. A retrospective review of this patient group demonstrates that approximately 80% of patients require one to three doses of morphine in the first 12 - 16 hours after the procedure. Even a single dose of intravenous morphine can increase the incidence of vomiting in children undergoing day surgical procedures.

What participants receive

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

  • bupivacaine with epinephrine (mid and upper abdomen)Procedure or surgery

    Patients will receive localized infiltration of local anesthesia (0.25% bupivacaine with epinephrine 1:200,000) at the beginning of the procedure as is current standard practice. Localized anaesthetic of the mid and upper abdomen.

  • bupivacaine with epinephrine (transversus abdominis plane)Procedure or surgery

    0.6 cc/kg (to a maximum of 20 ccs) of 0.25% bupivacaine with epinephrine 1:200,000 will be injected into the neuro-vascular plane between the internal oblique and transversus abdominis muscles. Regional anaesthetic block of the transversus abdominis plane.

What is being measured

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

  1. Morphine consumption

    Measured: For 24 hours after the time of first eye-opening post-procedure

  2. Pain, sedation, nausea & vomiting scores

    Measured: Pre-procedure; every 15 minutes from time of first eye-opening post-procedure until discharge from post-anesthesia care unit (PACU); on the ward at 2, 4, 8, 12, 16, and 24 hours

Secondary outcomes (2)
  1. Time until the patient is discharged from PACU to the ward

    Measured: At time of PACU discharge

  2. Parent satisfaction with analgesia and the procedure

    Measured: On the day following surgery

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing bupivacaine with epinephrine (mid and upper abdomen) and bupivacaine with epinephrine (transversus abdominis plane) in people with Anesthesia and Enteral Nutrition, run by The Hospital for Sick Children at 1 site in Canada.

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 4 inclusion and 11 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 24 Jul 2013. 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 Canada. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early. Results are not available in the source record.

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?

Morphine consumption (time frame: For 24 hours after the time of first eye-opening post-procedure). 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?
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 24 Jul 2013.
