Brief Summary
The goal of this multicentre, double-blind, randomised controlled trial study is to learn if the use of a nasal spray to open the nasal passages and increase airflow before surgery can reduce the occurrence of perioperative respiratory adverse events in children with upper respiratory tract infection who are undergoing anesthesia. The main questions it aims to answer are:
- Does use of a nasal decongestant (Oxymetazoline 0.05%) reduce perioperative respiratory adverse events during emergence (when waking up from anesthesia) or in the post-anesthesia care unit in children.
- Is it easy and acceptable to doctors, children and parents to use the nasal decongestant treatment? Researchers will compare the nasal decongestant to a placebo (a look-alike substance that contains no drug) to see if it works to reduce perioperative respiratory adverse effects. Participants will:
- Take a nasal decongestant or a placebo prior to surgery (just before anaesthesia is given)
- Be monitored during and after surgery in the post-anaesthesia care unit for any perioperative respiratory adverse events.
- Be asked about how acceptable they found the treatment.

Outcome Measures
Primary Outcomes (1)
Incidence of perioperative respiratory adverse event (PRAE) following the delivery of a nasal decongestant (Oxymetazoline 0.05%) or placebo prior to surgery under anesthesia in children with upper respiratory tract infection
PRAE will be defined as laryngospasm, bronchospasm, severe persistant coughing, hypoxaemia (\<95% for at least 10 seconds), airway obstruction, stridor or pulmonary aspiration. Incidence will be assessed by the clinician caring for the patient. Incidence is binary - yes if PRAE occured, no otherwise.
On day of surgery: Perioperative period. PRAE will be assessed if it occurs anywhere along the perioperative pathway between the beginning of the patient's emergence from anesthesia and their discharge from the post-anesthetic care unit (PACU)
Secondary Outcomes (6)
Assess the incidence of severe PRAE during emergence or in PACU in children who received the decongestant spray compared to the control group.
Day of surgery: Perioperative period. Severe PRAE will be assessed if it occurs anywhere along the perioperative pathway between the beginning of the patient's emergence from anesthesia and their discharge from the post-anesthetic care unit (PACU)
Assess the incidence of minor PRAE during emergence or in PACU inchildren who recieved the decongestant spray compared to the control group.
Day of surgery: Perioperative period. Minor PRAE will be assessed if it occurs anywhere along the perioperative pathway between the beginning of the patient's emergence from anesthesia and their discharge from the post-anesthetic care unit (PACU)
Evaluate the acceptability of nasal decongestant use at the induction of anesthesia in children with upper respiratory tract infection aged 4 and older and their parents/guardians
Patients and parents/guardians will be asked to rate the intervention post-operatively, prior to their discharge from hospital.
Evaluate the acceptability of nasal decongestant use at the induction of anesthesia by the treating anaesthetist
Treating anaesthetists will be asked to rate the intervention immediately after the administration of the interventional product.
Incidence of any potential adverse effects related to the administration of the nasal decongestant/placebo
Any potential adverse effects will be assessed from the administration of the interventional product until the patient's discharge from hospital.

Study Arms (2)
Decongestant nasal spray (oxymetazoline hydrochloride 0.05%)
ACTIVE COMPARATORDecongestant nasal spray, oxymetazoline (0.05%). Specific: 2.5mL of oxymetazoline 0.05% dispensed into amber brown 15ml bottles with pump and actuator attached. Children aged 1 to 5.99 years will receive 1 spray of either the nasal decongestant or placebo into each nostril, while children aged 6 years and above will receive 2 spays per nostril. Administration will be recorded on the standard patient's Medication Chart.
Placebo Comparator : Placebo spray (control group)
PLACEBO COMPARATORMatched Placebo spray. Specific: 2.5mL of normal saline 0.9% and benzalkonium chloride 0.02% dispensed into amber brown 15ml bottles with pump and actuator attached. Dose: children aged 1 to 5.99 years will receive 1 spray of either the nasal decongestant or placebo into each nostril, while children aged 6 years and above will receive 2 spays per nostril. Administration will be recorded on the standard patient's Medication Chart.
Interventions
Decongestant nasal spray containing active ingredient.
Control nasal spray containing no active ingredient.
