Nasal spray to reduce breathing problems around anesthesia in children with colds

Nasal Decongestant Administration to Reduce Perioperative Adverse Events in Children With Upper Respiratory Track Infections Having General Anesthesia - a Low Risk Intervention. (NARWHAL)

Phase 4 Interventional Telethon Kids Institute · NCT07000877

This trial tests whether a nasal decongestant spray given just before anesthesia can reduce breathing complications in children aged 1 to 8 with a recent upper respiratory infection who are having surgery.

What this trial studies

This is a multicentre, double-blind, randomized controlled trial enrolling 200 children aged 1 to 8 years with a current or recent (less than 2 weeks) upper respiratory tract infection who require general anesthesia. Participants are randomized at induction to receive either oxymetazoline 0.05% nasal spray or a placebo spray delivered with the same bottle/actuator. Perioperative respiratory adverse events (laryngospasm, bronchospasm, severe coughing, airway obstruction, oxygen desaturation <95%, and postoperative stridor) are monitored throughout the procedure and in the post-anesthesia care unit. The trial also records acceptability and ease of use for clinicians, children and parents.

Who should consider this trial

Good fit: Children aged 1.0 to 8.99 years with a current or recent (<2 weeks) upper respiratory tract infection who are scheduled for elective or urgent general anesthesia and meet other trial criteria are ideal candidates.

Not a fit: Children with ASA III or higher, known significant cardiovascular/respiratory/neurological disease, thyroid disease or diabetes, those already using nasal decongestants, undergoing nasal surgeries, or requiring endotracheal tube/face mask/high-flow nasal oxygen are excluded and unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this simple, low-cost nasal spray could reduce the risk of serious breathing complications during emergence and recovery, making anesthesia safer for children with recent colds.

How similar studies have performed: Topical decongestants like oxymetazoline are well established for relieving nasal congestion, but randomized evidence specifically showing reduced perioperative respiratory adverse events in children is limited.
