Key study: Efficacy of nebulized L-epinephrine for treatment of croup: a randomized, double-blind study

Visit

Eghbali A, Sabbagh A, Bagheri B, Taherahmadi H, Kahbazi M

Objective: The objective of this study was to compare the effect of L-epinephrine plus dexamethasone vs. dexamethasone for treatment of croup in children.

Key study: The comparative effectiveness of prednisolone and dexamethasone for children with croup: a community-based randomized trial

Visit

Garbutt JM, Conlon B, Sterkel R, Baty J, Schechtman KB, Mandrell K, Leege E, ...

Objective: Our objective was to compare the effectiveness of prednisolone 2 mg/kg for 3 days, a treatment regimen already commonly prescribed by pediatricians in our community; with one dose of dexamethasone 0.6 mg/kg, a treatment regimen known to be effective in the ED setting, for children with mild or moderate croup diagnosed at an office visit.

Key study: The comparison of oral and IM dexamethasone efficacy in croup treatment

Visit

Soleimani G, Daryadel A, Ansari Moghadam A, Sharif MR

Objective: In this study, the efficacies of intramuscular and oral dexamethasone administration are compared for treatment of croup.

Key study: How fast does oral dexamethasone work in mild to moderately severe croup? A randomized double-blinded clinical trial

Visit

Dobrovoljac M, Geelhoed GC

Objective: For children with croup controversy remains over dosage and time to onset of action of oral steroids. The Cochrane Collaboration and other reviews have suggested 0.6 mg/kg dexamethasone be used (despite some evidence that 0.15 mg/kg is effective) with no expectation of benefit before 4-6 h. This randomized double-blinded clinical trial examines whether 0.15 mg/kg dexamethasone works by 30 min. Published: 2012.

Key study: Seasonality patterns in croup presentations to emergency departments in Alberta, Canada: a time series analysis

Visit

Rosychuk RJ, Klassen TP, Voaklander DC, Senthilselvan A, Rowe BH

Objective: We examine the monthly patterns of young children who made croup-related visits to EDs in Alberta, Canada.

Key study: The effectiveness of local corticosteroids therapy in the management of mild to moderate viral croup

Visit

Eboriadou M, Chryssanthopoulou D, Stamoulis P, Damianidou L, Haidopoulou K

Objective: The purpose of this study was to determine whether local anti-inflammatory therapy with inhaled beclomethasone dipropionate is effective in the outpatient management of acute viral croup.

Key study: A randomized comparison of dexamethasone 0.15 mg/kg versus 0.6 mg/kg for the treatment of moderate to severe croup

Visit

Chub-Uppakarn S, Sangsupawanich P

Objective: The aim of this study was to investigate the effectiveness of dexamethasone 0.15 mg/kg single dose compared with the recommended dose of 0.6 mg/kg for treatment of hospitalized children with moderate to severe croup.

Key Study: Controlled delivery of high vs low humidity vs mist therapy for croup in emergency departments: a randomized controlled trial

Visit

Scolnik, D, Coates, AL, Stephens, D, Da Silva, Z, Lavine, E, Schuh, S,

Objective: To determine whether a significant difference in the clinical Westley croup score exists in children with moderate to severe croup who were admitted to the emergency department and who received either 100% humidity or 40% humidity via nebulizer or blow-by humidity.

Key Study: A randomized trial of a single dose of oral dexamethasone for mild croup

Visit

Bjornson, CL, Klassen, TP, Williamson, J, Brant, R, Mitton, C, Plint, A, Bull...

Objective: The primary outcome was a return to a medical care provider for croup within seven days after treatment. The secondary outcome was the presence of ongoing symptoms of croup on days 1, 2, and 3 after treatment. Other outcomes included economic costs, hours of sleep lost by the child, and stress on the part of the parent in relation to the child's illness.

Key Study: Outpatient treatment of moderate croup with dexamethasone: intramuscular versus oral dosing

Visit

Rittichier, KK, Ledwith, CA,

Objective: Steroid use for the treatment of croup has been supported by several studies, although few have addressed the use of oral dexamethasone for outpatient management. The efficacy of oral (PO) versus intramuscular (IM) dosing of dexamethasone in the outpatient treatment of moderate croup are compared in this study.

Key Study: A comparison of nebulized budesonide, intramuscular dexamethasone, and placebo for moderately severe croup

Visit

Johnson, DW, Jacobson, S, Edney, PC, Hadfield, P, Mundy, ME, Schuh, S,

Objective: To study how budesonide compares with dexamethasone, the conventional therapy for croup, and whether either reduces the rate of hospitalization.
