About this study

Official title: Intranasal Dexmedetomidine Plus Ketamine for Procedural Sedation in Children: an Adaptive Randomized Controlled Non-inferiority Multicenter Trial

Orthopedic injuries comprise more than 10% of ED visits in children and 25 to 50% of children will sustain a fracture before age 16 years. Distal radius fractures account for 20-32% of fractures in children, making them the most common fracture type. Between 20 and 40% of extremity fractures in children require a closed reduction, often necessitating procedural sedation and analgesia (PSA). Intravenous (IV) ketamine is the most commonly used sedative agent used to perform a closed reduction. However, children rate IV insertion as the most painful hospital experience, second only to the injury itself. IV insertion can be more technically difficult in children because of smaller veins and lack of cooperation, often leading to multiple IV attempts. A combination of intranasal (IN) dexmedetomidine plus ketamine (IN Ketodex) may provide effective sedation for children undergoing a closed reduction without the distress and pain related to IV insertion. A less painful experience has been found to correlate with child satisfaction which may reduce caregiver anxiety and improve the therapeutic relationship with the health care team. This study is a multi-centre, two-arm, randomized, blinded, controlled, non-inferiority trial designed to test the hypothesis that IN Ketodex is non-inferior to intravenous (IV) ketamine with respect to depth of sedation as measured using the Pediatrics Sedation State Scale (PSSS).

Read the detailed description

Intranasal medications may offer a technically easier and pain-free approach to procedural sedation (PSA); one that may have widespread applicability in patients with needle-phobia, difficult IV access, resource-limited settings, or when experience placing an IV is limited. Although IN ketamine has been found to be effective for fracture pain, procedural pain, anesthetic pre-induction, and diagnostic imaging, a recent shortage of this agent in the highest concentration of 100 mg/mL has severely limited out ability to study its effectiveness and consequent clinical uptake. Our research team conducted three systematic reviews of randomized trials of IN ketamine and IN dexmedetomidine in children undergoing painful procedures. The latter review included 18 trials (n=2128) of children age 1 month to 14 years. Our review found that IN dexmedetomidine, dosed from 1-4 mcg/kg, was well tolerated and superior to conventional sedatives (midazolam and chloral hydrate) in providing adequate sedation to 525/669 (78.5%) children. A number of studies found that IN dexmedetomidine was in fact superior to IN ketamine. Surendar et al. found that IN dexmedetomidine at 1.5 mcg/kg facilitated successful sedation in 18/21 (86%) of children undergoing dental procedures and was more effective than IN ketamine 5 mg/kg. Gyanesh et al. found that the proportion of children with satisfactory IV sedation was greater with IN dexmedetomidine 1 mcg/kg compared to IN ketamine 5 mg/kg [47/52 (90%) versus 43/52 (83%), respectively]. Mostafa et al. found that IN dexmedetomidine 1 mcg/kg was more effective at facilitating caregiver separation than IN ketamine 5 mg/kg or IN midazolam 0.2 mg/kg [30/32 (92%) versus 22/32 (69%) versus 28/32 (88%), respectively]. Moreover, a combination of dexmedetomidine and ketamine appeared to be superior than either agent alone. Qiao et al. found that IN dexmedetomidine 2 mcg/kg and oral ketamine 3 mg/kg in children undergoing IV insertion was superior to both IN dexmedetomidine 2.5 mcg/kg and oral ketamine 6 mg/kg alone (80.1% versus 47.6% versus 68.3%, respectively). Bhat et al. found that a combination of IN dexmedetomidine 1 mcg/kg and IN ketamine 2 mg/kg versus IN dexmedetomidine 1 mcg/kg alone facilitated greater acceptance of face mask (67% versus 52%, respectively) and greater tolerance of caregiver separation (93% versus 89%, respectively) (38). We also found evidence that higher doses of IN dexmedetomidine were more effective. More specifically, at the higher end of the dosing range (1-4 mcg/kg), IN dexmedetomidine 3 mcg/kg was superior to IN ketamine 7 mg/kg; providing adequate sedation to 25/29 (86.3%) versus 23/29 (79.4%) of children undergoing IV insertion, respectively. A dose-finding study of IN dexmedetomidine in children < 3 years who were post-operative from cardiac surgery and were undergoing transthoracic echocardiography found an optimal median effective dose of 3.3 mcg/kg (range 2.72-3.78 mcg/kg). Taken together, our review suggests that the most effective and tolerable intranasal agent for procedural sedation for fracture reduction is a combination of IN dexmedetomidine 4 mcg/kg and IN ketamine 2-3 mg/kg. There is ample and ongoing evidence of suboptimal management for procedural pain in children, a high frequency of orthopedic injuries requiring IV placement for PSA, and a lack of evidence to support the use of strategies that reduce the pain of IVs. However, there are no studies that have shown the effectiveness of IN ketamine for fracture reduction in children. In order to provide robust evidence supporting an alternate approach that precludes the need for an IV in children undergoing PSA, the investigators propose a study to answer the important research question: In children presenting to the ED with an orthopedic injury requiring PSA, does IN Ketodex provide as effective sedation as IV ketamine?

What is being measured

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

  1. Adequate sedation

    Adequate is defined as fulfillment of all three of the following criteria:

    (i) A Pediatric Sedation State Scale (PSSS) score of 2 or 3 for the duration of the procedure (defined for closed reduction as the interval of time from the first application of traction or manipulation of the injured limb for the purpose of anatomical realignment to the last application of a realigning force). The PSSS is scored from 0 to 5 in discrete integer values every 15 seconds. A score of 4 or 5 indicates under-sedation and a score of 0 or 1 indicates over sedation.

    (ii) No additional medication is given during the procedure for the purpose of sedation.

    (iii) The patient did not actively resist, cry, or require physical restraint for completion of the closed reduction.

    Measured: Through study completion in the ED (4 hours)

Secondary outcomes (3)
  1. Length of stay

    Defined as the time recorded in the medical record between triage and discharge.

    Measured: Through study completion in the ED (4 hours)

  2. Time to wakening

    This will be defined as the duration of time between the first pair of IN sprays and the first PSSS score of > 3 post-closed reduction.

    Measured: Through study completion in the ED (4 hours)

  3. Adverse effects

    Adverse effects as defined by Health Canada reporting standards

    Measured: Through study completion in the ED and up to 72 hours post-discharge

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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Naveen Poonai, MD (5196858500, naveen.poonai@lhsc.on.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adequate sedation (time frame: Through study completion in the ED (4 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 NCT04195256, 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 5 Nov 2024.
