Effect of Chewing Different Flavor Gum on Procedural Pain and Fear

Needle-related procedures such as venipuncture are among the most common sources of pain, anxiety, and fear in pediatric clinical care. Negative experiences during these procedures may reduce cooperation, increase procedural difficulty, and contribute to long-term avoidance of healthcare settings. Identifying simple, low-cost, and non-pharmacological strategies to improve children's comfort during venipuncture is therefore an important clinical priority. Chewing gum has been proposed as a potential method for modulating pain and anxiety through mechanisms such as distraction, rhythmic oral motor activity, and sensory engagement. Different gum types, including sugared and sugar-free varieties, may influence children's sensory experience differently. However, evidence regarding the use of chewing gum during pediatric procedures remains limited. This randomized controlled study is designed to examine the effects of chewing sugared and sugar-free gum on pain, anxiety, and fear in children undergoing venipuncture. A total of 144 children aged 7-12 years will be recruited from outpatient clinical units between November 2024 and January 2025. Participants will be randomly assigned to one of three groups: a control group (no gum), a sugared gum group, or a sugar-free gum group. Children in the intervention groups will chew their assigned gum prior to and during venipuncture. Pain will be measured using the Visual Analog Scale (VAS) and the Pen Pain Scale (PPS). Fear will be assessed using the Children's Fear Scale (CFS). Crying duration will be recorded as a behavioral indicator of distress. Demographic and clinical variables will also be collected to control for potential confounders. Data will be analyzed using appropriate non-parametric and categorical statistical tests, including the Kruskal-Wallis test, chi-square test, and Spearman correlation analysis, with a predefined significance level of p \< .05. The findings of this study are expected to contribute to the growing body of literature on non-pharmacological interventions for pediatric procedural support and may provide evidence for the integration of chewing gum as a practical technique to improve children's comfort and cooperation during venipuncture.
