off day...

So I have to say Im officially having an "off" day. My shift tonight started out BUSY. We as the medics didnt have any calls, but the ER was swamped, and on divert for at least 6 hours. Things eventually calmed down and I was really getting into the game I was playing onmy laptop when the tones sound for an unconscious male, and it was my turn to take a call. As I am enroute further from dispatch is possible cardiac arrest. I keep waiting for the ambulance to mark up, and I wait, and I wait, and I wait. I request PD while Im enroute to the scene (fearing I will be left attempting a code by myself, I assume they can at least provide some man power). I arrive to find a rather large man in his 30s in cardiac arrest with 2 obviously distraught female bystanders.
Long story short: I get a bystander to help me with CPR for 5-7 min until another medic and PD and BLS crews show up. Pt is DRT, in asystole. I attempted an intubation, get no breath sounds but get gurgling, and then stomach distention. So I try a King, no distention this time but only gurgling and no air movement in lungs, so I try the fix all of airway devices, the S.A.L.T.....and still NOTHING, only copious amounts of vomit! My medic partner takes a look and sinks a tube....WTH?!?!?

We get to the ED and of course the doc calls it within 2 min. Then they start examining the body and they find track marks that I would never have seen in a house lit by one 30 watt bulb lamp and they find ice, yes ice cubes, down this guys pants (I had heard of this but never experienced it for myself....) So who knows??

It really affected me that I was unable to get the airway on this pt. I have no idea what, if anything, I was doing improperly and would it have made a difference? Oh, and of course it didnt cross my mind to give narcan a shot....I have been a medic for 29 months now and I still feel so insecure at times....
