Could you define inappropriate fluid therapy for me here Vene? You've got a pt. with a sys down in the 50's are you still holding that its inappropriate for me to toss a 20cc/kg bolus his way? (88y/o Seated syncope, altered, rigid abdomen/cramping lower abd px, cold skin etc.)
It is patient specific. But, generally if adding fluid makes the patient numbers look nicer but worsens the condition, it is inappropriate.
If you seriously suspect a AAA, adding pressure adds to blood loss. It can make a small hole a complete rupture. (paramedic assisted death)
You see it in other conditions, not only with bleeding, like cardiogenic shock of various etiology.
Likewise the reverse is true. A patient in cardiogenic shock from septal anterior motion actually benefits from fluid bolus.
Citing yor example, would you rather deliver an unconscious patient to the ER with a systolic of 50, 40, 30 over garbage or doing chest compressions with a BP of 0/0 and an intrisic heart rate of 0 and in irreversible shock?
If the patient is in progressive shock, the crystaloid does nothing for them anyway. They need oxygen offloading capacity to help. In 2011 that means a blood product.
Would the patient be better off in a basic squad that could do nothing or an advanced squad that was making their situation worse?
Can you always come up with the exact differential in the field? Hell no. Anyone who thinks they can is either a fool or a liar.
But you have to make a decision. Right or wrong, it is your call and you live with the consequences. Choosing to follow a formula irrespective of patient condition is a choice. It is a choice providers make every day. But that choice may sometimes mean that you took away what little chance the patient had. It means that you may have made things worse than no medical help. It means that you are not treating patients who do not fall into the most causes or presentations.
You have to decide for yourself if you are ok with that.
Sometimes discretion is the better part of valor.
