Modeling the Distribution of Scald Type Burns in a Child

Area of Science:

• Forensic Science
• Pediatric Burn Analysis
• Injury Biomechanics

Background:

• Scald burns from spills or splashes are common in both accidental and intentional injury cases.
• Medical examiners analyze burn patterns to differentiate between various trauma scenarios.
• Understanding liquid dynamics on skin is crucial for forensic investigations.

Purpose of the Study:

• To model and document scald burn patterns resulting from various liquid spill and splash scenarios.
• To investigate how subject movement and anticipation affect burn staining patterns.
• To provide a reference for interpreting scald injuries in forensic evaluations.

Main Methods:

• An 8-year-old subject was subjected to five distinct colored water spill/splash scenarios.
• Video and still photography documented the resulting staining patterns.
• Scenarios included thrown liquid, spills, and saucepan-induced burns.

Main Results:

• Large, confluent staining zones at initial contact points were observed.
• Elongate runoff patterns and droplet stains were noted, following gravitational flow.
• Unique staining patterns, such as inverted U-shapes on buttocks and patterns from evasive movements, were documented.

Conclusions:

• Modeling scald burn history can support or refute proposed explanations for injuries.
• Subject's ability to anticipate and move can create unique, multi-surface staining patterns.
• These findings aid medical examiners in reconstructing events leading to scald injuries.
