Introduction: Flexible nasolaryngoscopy (FNL) is a common, uncomfortable procedure performed to assess the upper airway in infants. Oral sucrose is used during various painful procedures in infants but has not been used during FNL. Our objective was to understand the impact of oral sucrose on discomfort in infants undergoing FNL.
Methods: Infants (<12-months-old) undergoing FNL in the otolaryngology clinic were randomized to treatment (0.5 mL 24% oral sucrose) or standard management (no sucrose). Sucrose was administered <2 min prior to FNL performed by a single endoscopist. Outcome measures included: EVENDOL pain scale and cry duration and visit duration. Infant discomfort was measured by a second observer who was blinded to treatment group.
Results: Forty-seven infants were included, 23 were treated with sucrose and 24 with standard management. The median (IQR) age was 3.0 (2-5.7) months. There were no significant differences in age, weight, or sex across groups. The median (IQR) duration of FNL was 35.2 (26.5-58.4) and 36.4 (28.9-51.8) seconds for treatment and standard management groups, respectively. Mean (SD) EVENDOL scores were significantly lower in the sucrose group [4.9 (2.0)] than standard group (6.7 [2.1]) (p = 0.003). Mean cry duration after FNL was significantly shorter in the sucrose group (29.9 [20.4] seconds) than the standard group (52.7.0 [40.6] seconds) (p = 0.02). Median (IQR) visit duration did not differ across groups (1.1 [0.9-1.3] vs. 1.1 [0.7-1.4] h [p = 0.15]).
Conclusion: Oral sucrose given before FNL reduced EVENDOL scores and cry duration after FNL and did not prolong clinic visits in this randomized pilot study.
