In Pediatric age group, the most common feature of polytrauma is
Hypothermia
Hypotension
Hypovelomic shock
Hypoxemia
As the surface area to body volume ratio of children is high, thermal energy loss is higher and hypothermia is a higher risk. Due to the greater physiological capacity and ability of children to compensate for the fluid loss, hypotension is a very late and ominous sign of hypovolaemic shock.
