I'm not PICU, but worked in Pediatric Level ! Trauma for years. I sent a teenager to the Burn Unit one night. Report was high temp flash burns to the face, 9% BSA all to the head, with airway involvement. He was sedated, paralyzed for transport, and coming by 'copter. I've got sterlie sheets on the bed, we're all gowned up and expecting, well .. a burned kid. The 'copter crew comes strolling through the doors, chatting to each other (tip off #1), I don't smell "that smell" (tip off #2).
This kid gets over to the gurney and my attending and I just look at each other and at the same time say, "Where's the burn?". Literally. This guy had one single strip across his forehead that was red, one little bubble of blister, 1mm X 1mm at the left end. No airway involvement at all (and he had a full mustache, no singed hairs). He went up to Burn to let the Vecuronium and Versed wear off so he could be extubated and observed over night. He arrived in the ER at around 22:00, they were gone and driving home by 09:00 the next day.
