I ran this and was surprised at the outcome of it. Our station got dispatched for an Echo response (top priority) for a 6 yo female respiratory distress, possible respiratory arrest. ALS unit went enroute. I was on a BLS unit and was approximately 10 minutes out. We heard medics calling on scene for assistance to go to the LZ, so we went. Pt was 6 yo female who had been sick for approx. 1 day. Pt has no medical history. She was running a fever, so her doctor told her parents to put her in the bathroom with a steam bath. Upon doing this, pt began experiencing extreme difficulty breathing and EMS was called. Upon ALS arrival, pt was breathing approx. 34-36 times a minute and a "crowing" noise was heard upon expiration. When asked if she was having trouble breathing, pt shook her head No. Pt was given 15L O2 non rebreather and was also given albuterol. IV was initiated and fluid run. Medics could not figure out what was wrong with her so they waited for the flight nurse to come on board before pushing meds. Flight nurse and medic also did not know what was wrong with her. Flew pt to children's hospital. So... what are your thoughts as to what was wrong and how would you have handled this situation?
