Study type
Description of intervention(s) / exposure
250mcg Fluticasone propionate (Flixotide Inhaler) or placebo metered dose inhaler (MDI) for a 2 week period prior to ENT surgery. 250mcg administered as 125mcg twice daily. Adherence is monitored through diary cards detailing doses taken and reasons for any missed doses, the number of actuations remaining on returned stock and phone calls during the 14 days prior to surgery to parents to track doses and maximise compliance.

Treatment: Drugs
Comparator / control treatment
Propellant (hydrofluoroalkane) only metered dose inhaler (MDI) for a 2 week period prior to ENT surgery.
Control group

Primary outcome [1] 319072 0
To assess the effect of treatment (Fluticasone propionate 250mcg per day) on the number of respiratory complications in the perioperative period.
Respiratory complications may include:
• Laryngospasm
• Bronchospasm
• Oxygen desaturation:
• Severe persistent coughing
• Stridor
Perioperative respiratory adverse events (PRAE) outcomes will be recorded during surgery and the recovery period in the post-anesthesia care unit (PACU)
Timepoint [1] 319072 0
Primary outcome assessed by PRAE outcomes during surgery and during the recovery period in PACU.
Secondary outcome [1] 366907 0
To assess the effect of treatment on the number of complications in the extended post-operative period. Complications may include:
• Wheeze
• Stridor
• Severe persistent coughing
• Pain
• Bleeding
This will be assessed by phone-calls during the 14 day follow-up period.
Timepoint [1] 366907 0
The extended post-operative period involves a 14 day follow-up post-surgery.
Secondary outcome [2] 366977 0
To determine the healthcare costs associated with any difference in post-surgery outcomes between the treatment groups.. To perform a health economics analysis, the following composite outcomes will be recorded:
• Length of time spent in theatre and recovery
• Unplanned admissions or prolonged hospital stays
• Additional treatments or pain relief required pre and post discharge
• Parental time off work and/or childrens time off school/day-care post discharge
• Readmission post discharge
• Additional visit to GP related to surgery post discharge
This will be assessed by a review of the participants medical notes and phone calls during the 14 day follow-up period.
Timepoint [2] 366977 0
Health economics analysis will involve a review of the above variables during the 14 day period post-surgery.

Brief summary
Children with asthma or recurrent respiratory symptoms are at an increased risk of developing respiratory complications such as bronchospasm in the perioperative period. These risks are higher in surgeries such as adenotonsillectomy. Seven out of ten children with both respiratory symptoms and airway inflammation experienced at least one respiratory complication compared with only 1 out of 10 children with respiratory symptoms but no active airway inflammation.
We hypothesize that children with recurrent respiratory symptoms screened for the presence of airway inflammation using the non-invasive measurement of exhaled nitric oxide and randomised to receiving ICS (Fluticasone propionate 250mcg per day) for 14 days prior to their adenotonsillectomy will be at a lower risk of having respiratory complications in the perioperative period compared with those receiving routine clinical care.
