Summary

The investigators hypothesized that oral Dexamethasone in addition to nebulized Salbutamol will improve the Bronchiolitis Clinical Severity Score,duration of treatment in the short stay unit,need for hospitalization and readmissions to the pediatric emergency in a subgroup of patients diagnosed as Bronchiolitis with either eczema and or a parental or sibling history of Asthma. Two groups randomized will be given Nebulized Ventolin plus either oral Dexamethasone or placebo for 5 days. Bronchiolitis severity score plus vital signs will be recorded regularly until patient is fit for discharge. Patients will be discharged on Ventolin inhaler and to complete the five days course of oral Dexamethasone Patients will be followed up for 7 days post discharge by telephone.

Detailed description

This is a prospective, randomized, double blinded controlled study. It will be conducted in the main Pediatric Emergency Centre in Qatar(Al- Saad),during the period of Jan 2010 - April 2012. The study has been approval by the Institution Research Board. The sample size will be 200 patients.100 patients in each arm. Patients triaged as moderate to severe bronchiolitis will be evaluated and eligible patients are admitted to short stay unit and managed as usual. History and full physical examination will be done by the attending physician and the nurse will check 02 sat., respiratory rate and pulse rate. The Bronchiolitis clinical severity score will be assessed and then guardians of eligible patients will be approached explaining the purpose and treatment modalities. Patients will be included after obtaining a verbal and written consent. A CXR and an RSV test will be done for all study patients upon recruitment. The attending physician will complete the data collection sheet A computer generated randomization code will be prepared by the statistician. A pharmacist will prepare the study medications and the placebo. Patients will be randomized to either one of the two treatments:- Ventolin-Dexamethasone group: Oral Dexamethasone 1mg/kg will be given for the first day and then 0.6mg/kg for the next 4 days in addition to the Ventolin nebulizations. Ventolin-Placebo group: Oral Placebo with a volume equivalent to that of Dexamethasone will be given for the first day and then for the next 4 days in addition to the Ventolin nebulizations. Nebulized Ventolin 0.5ml in 2 ml Normal Saline will also be given at 0, 30, 60, 120 and 180 minutes and then every 2hours. Bronchiolitis severity score and O2 saturation will be recorded at enrollment, then after 4,6 and 12hours then every 12 hourly until discharged. To give additional Ventolin nebulization will be decided clinically as per the discretion of the treating physician and will be recorded. Nebulized epinephrine will not be used except if the patient is severely distressed. Nebulized Epinephrine 0.5 mg/kg (max 5mg/dose) mixed in 3ml normal saline will be allowed for severely distressed patients as an add on therapy given on PRN basis.. Additional interventions such as Oxygen therapy, Intravenous fluids and PRN nebulized Epinephrine will be recorded as additional therapies. Patients fit for discharge will have their nebulization stopped \& date, time documented. Physician will discharge patients based on clinical grounds as not needing supplemental oxygen,minimal or no chest recessions,minimal wheezing or crackles and feeding adequately Patients will be sent home on Ventolin inhaler 2 puffs q 4 hours for 48 hours Then 2 puffs every 4 hours when needed plus the study medication syrup to complete 5days course. Follow up for one-week post discharge by a phone call daily will be conducted and patients will be assessed in PEC when needed.
