Waisman et al1have once more highlighted the very real challenge of triaging children in mass-casualty events (MCE) in the pre-hospital setting. Difficulties encountered measuring vital signs and different patterns of injury, reflecting significant anatomical and physiological differences, necessitates a modified approach when applying traditional “adult” triage methods to paediatric trauma victims. When using physiological parameters to triage children, their faster respiratory rates and heart rates frequently result in younger children being triaged to a higher category than their injuries demand. These differences become less apparent during adolescence, as the young person matures into adulthood.
