SOME cases benefit more from a longer on scene period, SOME need a snatch and run, most fall in between, because of reasons eveyone's tired of hearing me talk about. Rule out or in these "SOME" groups and work from there.
Im with you on the "it depends" answer.. i didnt vote in the poll.. because it really depends on what you're looking at. If you get on scene, and someone is shot, or its a trauma alert.. im gone before you realize i was there...literally.. 2 minute scene times...
if I arrive on scene of a chest pain, the FIRST thing im doing is a 12 lead to rule out an acute MI... because that completely changes the destination and treatment course you're going to use.
Altered level of consciousness is another good example.. you grab and go.. get in the truck.. begin transport. then find out the sugar is only 20.. you treat them.. and have an awake alert and conscious patient who either doesn't want transport.. or doesn't need transport.
Respiratory distress ... you need to do a good assessment. If i have a CHF exacerbation, im going to get them on my cot, in the truck, get a 12 lead.. 2 IV lines, initiate a tridal drip, and reassess them from there.. and either transport if they begin to improve.. or perform a Drug assisted intubation and get them on a ventilator with some PEEP if they arent improving.. ALL before i transport... while i still have my partner handy.. and a controlled enviroment (ie: not flying down the road lights and sirens trying to push meds, ventilate and intubate)
So it really depends on the situation... I think another user hit the nail on the head.. we need to start assessing and treating our patient's rather than giving them a fast glorified taxi ride.
In fact, here is the perfect example.. you get a call for a pediatric unknown.. walk in the house, and mom is freaking out and the kid is in cardiac arrest... how many of you are going to grab the kid and run like hell for the ER? (im talking ALS... BLS is a completely different story)
How many of you are going to work the child right where you're at.. and give them your best 20 minutes.. with good quality CPR and a good quality airway? (BLS airway typically, especially with children)
We just had this chat in our latest dept inservice and PALS renewal... our medical director and our Captain in charge of education and training made it a point to tell us to work the child on scene, and give it your best. The time you waste running for the truck and doing haphazard CPR all the way to the ER is going to ruin that child's chances for survival if there are any... not to mention, if the child does not recover ROSC on scene, you can pronounce and call the ME (at least in my agency, yours may be different) rather than transporting a dead child to the ER, which puts you, your crew, and the general public at risk...not to mention taking a dead child out of a house like that may be destroying and removing valuable evidence should this become a criminal case with law enforcement.
Just some examples.. YMMV
