Can you confirm that the change in dose from 0.8 to 0.4 IM was simply because we are trying not to wake these patients up?

Question: How fast can a pediatric Pt. burn through glucose stores? Scenario: Called for a 13y/o unconscious. Consumption of unknown amount of alcohol & unknown drugs or amount. AOx0, GCS 4=E2V1M1. Eyes open to pain as only response. Pt stable vital signs on Primary & throughout transport & BGL 5.8mmol/L on scene. Transport to appropriate children’s hospital code 4 CTAS 2with a 25 min transport time. On ED assessment Pt. was given an amp of dextrose as ED found BGL to be “low”…. or not able to read on meter, so possibly less than 1.6mmol/L. Crew’s service meter DID pass daily test procedure as per manufacturer’s guidelines. Thank you
