The goal of this pilot randomized controlled trial is to understand whether we can successfully conduct a larger definitive clinical trial in the future. The current pilot study will test various aspects of the larger trial and help us improve its design if needed. The investigators are mainly interested in knowing whether they can (1) recruit enough patients, (2) administer the intervention, and (3) collect all the data needed from patients. The definitive randomized controlled trial will assess if dexamethasone is superior to placebo for treating children and youth hospitalized with orbital cellulitis.
Age 2.00 months -17.99 years (prior to 18th birthday)
Confirmed or suspected diagnosis of orbital cellulitis as determined by the attending physician, medical team, and/or delegate's clinical judgement, based on one or more features of orbital cellulitis (i.e., ophthalmoplegia, pain and/or limitation with extraocular movements, chemosis, blurred vision, eye swollen shut, and/or proptosis).
Scheduled to be admitted or admitted to hospital for less than 36 hours.
Informed consent provided in accordance with institutional policies
Transferred directly from outside hospital inpatient setting to a participating hospital site's inpatient setting with over 36 hours having passed since admission to outside hospital. If within 36 hours, patient is eligible.
Treatment with IV or PO systemic corticosteroids within 1 week of presentation
Recent hospital admission for orbital cellulitis within 1 week of presentation
Current systemic fungal infection
Parallel
Dexamethasone 0.3mg/kg
DrugSANDOZ-DEXAMETHASONE SODIUM PHOSPHATE INJ USP 4MG/ML (5 mL vial) (DIN# 00664227) or any brand available commercially in the Canadian market. Dexamethasone 0.3 mg/kg (max dose 12 mg) will be given by IV after randomization. The second dose will be given 24 hours (+/-8 hours) after the first dose. The most recent weight recorded in the patient's chart will be used for the dose calculation.
Placebo Control
DrugSodium Chloride 0.9% Injection USP Placebo Baxter brand (or any commercially available in the Canadian market) given by IV, first dose administered after randomization and second dose 24 hours (+/- 8 hours) after the first.
Recruitment rate
Recruitment rate is measured as the number of patients agreeing to participate in the trial and are randomized, divided by the number of patients screened as eligible at 18 months after initiation of the trial recruitment (per site).
Intervention fidelity
Intervention fidelity is the proportion of randomized patients who receive the intervention or placebo at the correct dose and time, without receiving any off-protocol corticosteroids, at each site. It will be assessed 96 hours after hospital admission, defined as the patient receiving two doses of 0.3 mg/kg dexamethasone or placebo (first dose after randomization; second dose at 24 +/- 8hrs after first dose).
Completion of definitive trial primary and secondary outcomes
Completion of definitive trial primary and secondary outcomes is defined as the proportion of randomized patients with complete data for the definitive trial primary outcome (length of hospital stay) and the definitive trial secondary outcomes, at each site. The definitive trial secondary outcomes include: Surgical intervention, clinical outcomes (e.g. vision, pain, swelling), healthcare use (ICU admission, revisits to medical care and hospital), perceived stress experienced by parents, and adverse events.
