WOW, I am really amazed at the behaviors I have read here. Why not go to the doc that complained and say I was unsure of whom to call and in the future I will know. If its surgery related or is a expected result of surgery N/V, pain, increased temp etc. call the surgeon. If its BP or other complaint call the attending. Those of you that chose to give vindictivenss as advice. Bad advice. You want respect for the job you do, so do the docs. Remember the direct approach is always more effective than revenge.
