NCT07326254

Brief Summary

Needle-related pain and anxiety present persistent challenges in pediatric clinical procedures. This study aims to investigate the effects of chewing sugared and sugar-free gum on pain, anxiety, and fear in children undergoing venipuncture. A randomized controlled design will be used with 144 children aged 7-12 years to be recruited between November 2024 and January 2025. Participants will be randomly assigned to control, sugared gum, or sugar-free gum groups. Pain and fear will be assessed using the Visual Analog Scale (VAS), Pen Pain Scale (PPS), and Children's Fear Scale (CFS). Crying duration will be recorded as a behavioral indicator. Data will be analyzed using Kruskal-Wallis, chi-square, and Spearman correlation tests with a significance level of p \< .05. The study is intended to evaluate whether chewing gum can serve as a simple, low-cost, and non-invasive method to improve comfort and cooperation during pediatric venipuncture procedures.

Outcome Measures

Primary Outcomes (3)

  • Procedural Pain - Visual Analog Scale (VAS)

    Pain will be assessed using the Visual Analog Scale (VAS) to measure the severity of procedural pain during venipuncture in children assigned to control, sugared gum, or sugar-free gum groups. Units on a Scale. Minimum-Maximum Value: (0-10). Higher scores indicate worse pain

    Immediately following the blood collection procedure (within a few minutes)

  • Procedural Pain - Pen Pain Scale (PPS)

    Pain will be assessed using the Pen Pain Scale (PPS) to measure the severity of procedural pain during venipuncture in children assigned to control, sugared gum, or sugar-free gum groups. Units on a Scale. Minimum-Maximum Value: (0-5): Higher scores indicate worse pain.

    Immediately following the blood collection procedure (within a few minutes)

  • Procedural Fear - Children's Fear Scale (CFS)

    Fear will be assessed using the Children's Fear Scale (CFS) to measure the level of fear experienced by children during venipuncture in control, sugared gum, or sugar-free gum groups. Units on a Scale. Minimum-Maximum Value: (0-4). Higher scores indicate greater fear

    Immediately following the blood collection procedure (within a few minutes)

Secondary Outcomes (2)

  • Duration of Crying During Venipuncture

    From needle insertion until completion of venipuncture, with crying duration recorded in seconds, assessed for up to 5 minutes.

  • Parent Satisfaction With Child's Blood Collection Experience

    Immediately after completion of venipuncture (within 5 minutes).

Study Arms (3)

Sugared Gum

EXPERIMENTAL

Participants start chewing sugared gum one minute before the procedure and continue chewing until the procedure is over.

Behavioral: Sugared Gum Chewing

Sugar-Free Gum

EXPERIMENTAL

Participants start chewing sugared gum one minute before the procedure and continue chewing until the procedure is over.

Behavioral: Sugar-Free Gum Chewing

Control

PLACEBO COMPARATOR

This group did not receive any gum chewing intervention during the blood collection procedure. Standard procedures were followed. The parent was present with the child during the procedure.

Other: Control

Interventions

Chewing sugared gum, which began one minute before the procedure, continued until the end of the blood collection. Sugared gum provided a sweet taste stimulus, while sugarless gum served as a non-sweet comparator. Children were continuously monitored to ensure safety and prevent aspiration, and children aged 7-12 were included in the study. No adverse events were reported during the study.

Sugared Gum

Participants began chewing sugarless gum one minute before the procedure began, until the blood sample was collected. The purpose of the chewing activity was to reduce pain and fear during the procedure. No other behavioral or pharmacological interventions were administered.

Sugar-Free Gum
ControlOTHER

No active gum chewing intervention was performed during blood collection

Masking Details
Participants were randomly assigned to three groups: control (no gum), sugared gum, and sugar-free gum (n = 48 each) . Randomization was performed using sealed opaque envelopes labeled with group codes. Each child selected one envelope in the presence of a parent. The nurse who performed the blood draw and the researcher responsible for data collection were blinded to group allocation. Complete participant blinding was not feasible due to the visible nature of the intervention.
