So are you saying that you would not preform any ALS skills on said pt?
I am saying if I thought the pt had an ectopic pregnancy I would not delay transport to wait for an ALS unit to arrive if a BLS unit was already on scene and capable of immediate transport.
If I was an ALS unit that responded as the initial unit I would start a line in addition to other treatments based on my findings. In the event of a suspected ectopic I would make a determination if I was going to run fluid based on clinical signs of hemostasis. But either way I doubt the fluid would be a determining factor in outcome.(unless it was a massive hemorrhage in which case a fluid bolus would likely make it worse.) I would be more concerned about slowing or stopping the bleed. (which could also be done by an astute basic while in route to surgery)
I maintain slowing or stopping a bleed and rapid transport would be more effective in a ruptured ectopic pregnancy than any ALS procedure available on most squads in the US.
I also am not too bad at Hx and PE and could probably narrow down the diagnosis a little closer than abd pain as presented by the OP, which would determine exactly what treatment I thought appropriate in the event it was not likely an ectopic.
