Back in the day.. ha ha.. when I first began, which was a mere 14yrs ago.. we covered a truly massive area. Went to the edge of our 1st due, more than 30 miles out and picked up a chest pain patient. An ALS Squad unit assisted, did an EKG didn't find anything...and released care. Sent us on our way to the ER, which by patient choice, was over 45min away. Pain came in waves, so I called a different paramedic unit to intercept. Just because. I went head to toe, b/c that's what I was taught. Felt something strange, it was like a balloon rapidly inflating and deflating, a balloon within a balloon. The vitals, as I recall, were relatively normal. Then the patient had a sudden onset of pressure in the abdomen, with pale skin, diaphoresis and hypotension. Medic got on, did the EKG, said, probably an MI, stop at the nearest ER. I suggested it was something more, which he sort of ignored b/c I was fresh out of the box. Described it. He felt. Met a chopper along the road. Patient survived his ruptured AAA.
I've had several AAA patients, and I always thought - should I palpate or shouldn't I? Will it cause it to rupture? Usually, they were already ruptured.
