Very true Noyac and FFP. Cardiac is my bread and butter so when I see sick patients I tend to approach them that way. Personally, I hate digging under drapes and hunching over and putting in "less sterile" central lines, when I can do it at the beginning, sterile, and if need start my infusions if his heart can't handle the case. So I tend to look at it as: 1) the patient could need it and 2) yes, it makes me feel better.
No the CVP won't tell me anything about his heart function, per se. My thoughts are, why wait for trouble to build up my arsenal and instead have my arsenal ready when trouble arrives.
Alot of factors in this case, which is why I think it's funny when threads are like "EF 15%..would you do the case? K+ 5.2...would you do the case", so much more goes into the thought process. Even where I work I think we CVP people who don't need them (due to surgeon request), which is probably why I'm so quick to put one in if I think the situation may need it. But that's private practice for you. Keep the business happy.
