Insights

The red-and-white visual analog scale (VAS) effectively measures children's and adults' anticipated pain. Pain ratings for mild, moderate, or severe levels did not significantly differ across age groups.

Area of Science:

  • Pediatric Anesthesiology
  • Pain Management
  • Psychometrics

Background:

  • The traditional visual analog scale (VAS) is widely used for pain assessment.
  • Modifications like the red-and-white VAS aim to improve pain intensity rating, particularly in pediatric populations.
  • Understanding how different age groups perceive and report pain is crucial for effective pain management.

Purpose of the Study:

  • To compare anticipatory pain intensity ratings between children of various ages and adults using the red-and-white VAS.
  • To evaluate the reliability and applicability of the red-and-white VAS across diverse pediatric age groups and adult populations.

Main Methods:

  • One hundred children undergoing elective eye surgery and 50 healthy adults were interviewed preoperatively.
  • Participants rated their anticipated pain intensity using the red-and-white visual analog scale (VAS).
  • Statistical analysis focused on comparing median pain scores and ranges across different age cohorts (preschool, schoolchildren, adolescents) and between children and adults.

Main Results:

  • No significant differences were observed in the medians and ranges for mild, moderate, and severe pain ratings between preschool children, schoolchildren, adolescents, and adults.
  • The anticipated need for pain medication, indicated by a median score of 50% of the maximum, was consistent across all pediatric age groups.
  • The red-and-white VAS demonstrated comparable utility in assessing pain intensity perception across a wide age spectrum.

Conclusions:

  • The red-and-white VAS is a reliable tool for assessing anticipated pain intensity in children and adults.
  • Age does not appear to be a significant factor in how children and adults rate their expected pain using this modified VAS.
  • Findings support the use of the red-and-white VAS in preoperative settings for pediatric pain assessment.
