I know those beds all too well. My youngest son used to find it amusing to take the controls when the nurse wasnt looking, to see if he could squash me into the ceiling. Luckily it always stopped before I hit my head.
With regards to bruising, I think I had lots of bruising twice out of six procedures. The biggest problem I had was an ache in the inner thigh, up towards the groin, which made me walk like john wayne. Have you had the array of contraptions used on your entry site? like the sand bag and the clamp? After my initial MI, my blood was so thin they had trouble stopping the bleeding. I woke up with a very stiff leg and I couldn't believe it when I looked down and saw a sand bag laying over the wound. Half asleep, I thought it was a cleaner who left it there so I threw it on the floor and went back to sleep, only to be woken up by a very angry senior nurse. The heavy bag didn't work so a strange strap mechanism was then used which was even worse for discomfort. I had been heavily dosed with aspirin, plavix and clexane.
rofl..............lol.....too funny. After one, the hospital had a bed that would lift you up. Kind of like the chairs that elevate you up. So after all my screaming about my back hurting they elevated the entire bed until I was about at a 75 degree angle. Then the straw worked for me.
Maybe there are slightly different rules adhered to. I've had angiograms in three different hospitals in the UK and each time I have had to lay flat for 30 mins, then I'm elevated to 30 degrees for half an hour. Only though if there is no bleeding. If bleeding has occurred, you always jump back to stage one, the laying down flat position. A bit like go to jail do not pass GO. Then it's one hour sitting upright. If still no bleeding, get dressed and go home. However, they do give clear instructions in a leaflet what to look out for and what measures to take. So two hours has been the average for me.
I think it's fascinating how they have always insisted I have a drink in the 30 degree position using a straw. I still haven't got the hang of that and end up soaking wet. No twisting, sitting more upright or anything, just rest the drink somewhere near your body and try to get the straw into your mouth. It's beyong the realms of physics.
That happened to me the very first cath I had. (I've had 9 now, after yesterday's) No problems or anything to worry about, though. They accidently let the cath fall out and I had bleeding to my knee. It was not painful though. And I was at my usual workload the next day. The one thing that I am wondering though is why they allowed you to get up at all after only 2 hours? The minimum for me has always been 4. 6 if they stent anything. I seem to be having more trouble with the one they did yesterday than any of them, and they didn't stent, so no larger cath.
