Why should no more than 750 ml of urine be removed from the bladder at one time?

Because it can cause extreme sudden changes in pressure in the bladder and abdomen which may cause the blood vessels in the pelvis to become engorged which may possibly cause acute hypotension.

Not to mention the sudden fluid shift, would be equivlent to taking 750 out of a vessel....also consider that if you deflate too quickly, you're putting pressure on the ureters and kidneys...

Just like a pirate...way to steal the first response.... ;)

Wow this is so different from what happenes in the real world. If someone has more than 750 cc in the bladder they are usually in agony and we just let the foley fill. Interesting.

I was taught no more than a 1000ml but that was some years ago. But I havent' seen it done in practice.

But the posters are correct it is because of the sudden shift of fluid.

Well you see a lot of things in clinical setting that aren't done the "correct" way. ;)

I'm going to try to do things the way Potter and Perry say to help prevent harm to my patients. :D

I heard last year from my Clinical Instructor that we shouldnt take out more than 1000 at a time.

However, I asked nurses at my current clinical placement and they said that the urologist told them that it does not cause any of the problems mentioned above.

I am stilll confused on who to believe...!!!

We were told over 1,000 could lead to bladder spasms. Never seen it, only huge relief.

Ok, question for you then... hopefully this isn't something I should have done, but the RN I was with didn't say anything about it. About 3 weeks ago at clinicals, we received a patient from another facility and the pt's bladder was seriously distended and stated he hadn't voided all day (diff from report from RN at other facility) so we bladder scanned him and showed 933 mL. We straight cath'd him and got out about 980 mL. How would I have stopped at 750 mL without causing him some pain and making a huge mess? Thanks for any feedback!

kink the plastic part of the tubing to allow urine to build up, and use the clamp attached to the line.

Hi! You would just clamp it. ;)

p.s. ~ however, I'm learning now that at some places it is being taught that removing >750 mL from the bladder does not cause that problem. Who knows...
