Ugh...just went throught this yesterday. Brought back our second pt after turning over the room, CRNA and I got her settled, everything was already for the surgeons and they weren't there- waited a few minutes, asked the CRNA and tech if I was supposed to call them (??? c'mon, you know you have another pt!!) They work with this group frequently, I don't. No I was assured they always come in on their own. Many minutes later I said I'm impatient, I'm calling (we call the secretary who pages for us) Many minutes later they breeze in casually and say you should have paged us, we were waiting for you to page.

We have delay codes we use to keep track anytime we're running behind so we know where our problems and trends are. We actuall have one for "surgeon lost between cases" I thought that was funny until yesterday.
Fact is, Most of our surgeons need to be summoned. We never take back the first pt of a suergeon's day until we have seen him/her for ourselves but following cases have a fairly predidctable turnover so although they don't wander far (unless they tell us, then we hold of) they do wander a little- they might be in another OR, "Dr's" lounge, "nurse's" lounge, front office, etc. It's a few extra seconds to call the sec on speed dial and say we're ready for so and so but it usually works well. Some Drs are predictible and we call ourselves over the intercom directly from, say, the Dr lounge.
Catching up with CRNA/MDA is almost never a problem. If it is it's usually because of a delay on my end and now they got involved helping a collegue and they catch me by the time the pt and I make it to the OR door. Hey, sometimes they take a pt back without me while I grab supplies for a last minute request.
