For general practitioners, emergency assessment of a critically ill or injured child can be difficult, as history is usually given by caregivers, physical examination may be challenging due to lack of cooperation and vital signs are potentially difficult to interpret because of age-related variations. The Pediatric Assessment Triangle (PAT) is a rapid and simple observational tool to standardize the initial assessment of children regardless of complaint or underlying diagnosis. It only uses visual and auditory clues, requires no equipment, and takes only seconds to perform. It allows clinicians to assess whether an urgent intervention is necessary or whether a more detailed history and physical examination may be done. Respiratory distress, gastro-enteritis with dehydration, febrile convulsions and traumatic brain injury constitute four common pediatric complaints that are encountered in a general practitioners consultation and will be discussed in some detail.
