In the Field
Pediatric trauma is different from adult trauma in ways that matter operationally. Children have larger heads relative to body size (different airway positioning), proportionally more blood volume per kg but smaller absolute volume (smaller losses are catastrophic), more elastic chest walls (significant intrathoracic injury without rib fractures), and weight-based medication dosing that does not tolerate the eyeballed adult dose approach. A 22 kg child given the adult tourniquet without consideration for limb size may have a tourniquet too long to apply correctly. A child given the adult ketamine dose is in for a rough emergence. Pediatric TCCC formalizes these differences.
Common Mistake
Using adult TCCC protocols unmodified in pediatric casualties. Tourniquet placement on a small limb may not achieve arterial occlusion; needle decompression site landmarks are different relative to body proportions; airway sizing requires careful selection. The other mistake is reflexively using length-based tools (Broselow tape, weight estimation by age) without confirming the result against actual patient size. Length-based estimates are calibrated to a specific population and may be inaccurate for malnourished, oversized, or atypical children.
Technical Detail
Pediatric TCCC adapts adult TCCC for casualties under approximately 50 kg or pre-pubertal physiology. Key differences: airway - larger occiput requires shoulder roll for neutral position; smaller airway diameter requires uncuffed ETT in young children; cricothyroidotomy generally contraindicated under 8 to 12 years due to cricoid cartilage anatomy (needle cricothyrotomy used instead). Hemorrhage - circulating volume approximately 70 to 80 mL/kg in children versus 65 to 70 mL/kg in adults; smaller absolute losses are proportionally more significant. Tourniquets - CAT and SOFT-T Wide accommodate pediatric limbs down to approximately 32 cm circumference (older toddler); smaller pediatric devices exist. Medications - all dosing is weight-based; Broselow tape provides length-based estimates with corresponding medication doses. Hypothermia - pediatric casualties cool faster due to higher surface-area-to-mass ratio; aggressive hypothermia prevention is critical.
