We can never cancel the medic especially when medication has been administered... I know just how easy it is for narcan to work- which is the problem... titrate to effect but not bring the person all the way back... or if they are opioid dependent you can cause other problems with narcan...
Why?
Why would you tie up another ambulance, especially a medic truck with a patient who's problem has been corrected?
And what other problems are you going to cause? A combative patient, not if your administering it correctly, vomiting, occluded airway? I can address those issues just as well if need be.
The problem is the latter generation of EMT with their compressed training and education has come to rely completely on paramedics, independent thought has been removed, replaced with call a paramedic even if the patient doesn't need one.
When I went to school there wasnt a medic truck on every corner and our education reflected that, we were educated/trained as sole providers able to care for patients, I simply don't drop back and punt if the complaint is in my grasp, we are are able to administer multiple medications, use advanced airways and such. I don't have to call a medic everytime I administer a medication, if it had the desired effect I take them to the hospital if it doesn't I contact some who can address it further.
