What this trial studies

This study evaluates the effectiveness of 24% sucrose solution in alleviating pain or distress in infants undergoing flexible nasolaryngoscopy at the SickKids Pediatric Otolaryngology Clinic. The research involves administering oral sucrose to infants scheduled for this procedure and measuring their pain responses. The goal is to determine if this simple intervention can improve the experience for young patients during a potentially uncomfortable diagnostic procedure.

Who should consider this trial

Good fit: Ideal candidates are infants under 12 months of age scheduled for flexible nasolaryngoscopy at SickKids.

Not a fit: Patients over 12 months of age or those with specific medical conditions that contraindicate the use of sucrose will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce pain and distress in infants during medical procedures.

How similar studies have performed: Previous studies have shown that oral sucrose can effectively reduce pain in infants during various medical procedures, suggesting a promising approach.
