Area of Science:

• Pediatric Burn Prevention
• Thermal Injury Research
• Household Safety

Background:

• Scald injuries are the leading cause of pediatric burns requiring hospitalization globally.
• A significant number of these injuries occur in the kitchen when children pull hot beverages onto themselves.
• Effective prevention campaigns for primary caregivers are essential due to the high cost and morbidity associated with scalds.

Purpose of the Study:

• To investigate the thermal characteristics of common household beverages.
• To determine the potential of these beverages to cause significant thermal injury in children.
• To inform prevention strategies for pediatric scalds.

Main Methods:

• Standardized preparation of common household beverages (tea, coffee, hot milk) at a controlled ambient temperature.
• Temperature measurements taken from ceramic mugs over a 10-minute cooling period.
• Analysis of cooling curves to assess thermal properties.

Main Results:

• Milky beverages initially registered lower temperatures (75-77°C) compared to black tea and coffee.
• Black tea and coffee maintained temperatures above 65°C for the full 10-minute cooling period.
• Adding milk (5-10ml) or sugar did not significantly alter cooling rates; however, increased milk volume lowered initial temperature.

Conclusions:

• Hot beverages, even after cooling or with added milk, can cause severe burns, particularly in children.
• A complacent attitude towards hot beverage safety must be addressed.
• Enhanced caregiver education is vital to reduce the incidence of household scald injuries in pediatric populations.
