Hello. I need to pick a topic on post-op complications. A lot of people are already doing pneumonia, incision infections. I recently encountered an elderly patient whose baseline is a&o x 3 who, 2 days after surgery pt started becoming disoriented on and off. I was told this was a big problem with elderly patients. I wanted to look into this more but haven't found much on the topic. So I am trying to see if it isn't really that common. I am wondering how many others have encountered something like this?If you have can you describe the behavior (how often confused, which post-op day did it start, how old was the pt, did they get over the delirium, etc.). Also if you know of a good recent article on the topic that would be very helpful.
