NCT05383495

Brief Summary

This is a 3-arm adaptive clinical trial to the optimal light sedative for reducing distress during laceration repair in children. The investigators will compare intranasal (IN) dexmedetomidine, IN midazolam, and nitrous oxide (N20). The primary outcome is the Observational Scale of Behavioral Distress - Revised (OSBD-R).

Outcome Measures

Primary Outcomes (1)

  • Observational Scale of Behavioral Distress - Revised (OSBD-R)

    Score ranges from 0 (no distress) to 23.5 (maximal distress) and will be scored for the time interval encompassing preparation and suturing

    During preparation, suturing, and recovery (20 minutes)

Secondary Outcomes (4)

  • Adverse effects

    From intervention to 72 hours post-discharge

  • Need for additional anxiolysis or sedation to facilitate repair

    During suturing (10 minutes)

  • Need for physical restraint

    During preparation and suturing (10 minutes)

  • Late maladaptive behaviors

    From discharge to 72 hours post-discharge

Other Outcomes (13)

  • Compliance with intervention administration

    From drug administration through completion of suturing (40 minutes)

  • Caregiver satisfaction with anxiolysis during laceration repair

    At discharge (1 minute)

  • Child satisfaction with anxiolysis during laceration repair

    At discharge (1 minute)

  • +10 more other outcomes

Eligibility Criteria

Age2 Years - 12 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • i) Age 2-12.99 years \[highest incidence of laceration repair\] ii) Single or grouped lacerations separated by no more than 2 cm for which the treating physician believes repair does not require IV sedation iii) Repair to involve sutures and performed by ED physician or designate (trainee) iv) Child or caregiver desires anxiolysis for laceration repair \[justification: incorporates family preferences based on their prior experiences or beliefs about child's response\] vii) Local anesthesia planned to involve topical anesthetic (LET), infiltrated lidocaine, ring, or thenar block

You may not qualify if:

  • i) Sedative, anxiolytic, or alpha-2-adrenergic receptor agonist \< 24 hours prior to interventions (may compound sedative effect and increase the SAE risk). 24-hours encompasses the duration of sedation of most agents.
  • ii) Hypersensitivity to any intervention iii) Occlusion of \> 1 nostril due to polyps, septal deviation, or foreign body (may prevent drug absorption) iv) Hemodynamic abnormalities: bradycardia or hypotension \< 2 SD of age-related normal value v) IND contraindications: Pre-existing renal insufficiency, uncorrected mineralocorticoid deficiency, pulmonary hypertension, uncorrected cyanotic heart disease, cardiac conduction disorder, pulmonary hypertension, pulmonary edema, vitamin B12 or folate disorder, phenylketonuria, or psychosis vi) Sedation contraindications: Impaired level of consciousness or respiratory instability vii) N2O contraindications: Conditions associated with potential accumulation of gas within body spaces viii) Suspected or confirmed pregnancy (as reported by patient) ix) Inability to vocalize pain due to motor deficits (unable to apply the OSBD-R) x) Caregiver unable to complete study tasks due to insufficient comprehension of either English or French in the absence of a native language interpreter xi) Weight \>= 65 kg (to avoid under-dosing of INM or IND) x) Not American Society of Anesthesiologists class I (healthy) or II (controlled mild to moderate disease) xii) No concomitant fracture or dislocation requiring orthopedic manipulation
