Every day in PACU is different, as every patient and surgery is different. No two surgeries are alike, and people emerge from anesthesia differently as well. I do both PACU and I also sedate patients. Some patients roll out of OR into PACU up and awake, some take very long to wake up, some have airways in place or an ETT. Two people can have the same surgery, one has no pain, the other has severe pain. It's not an easy dept. to work in, can be very fast paced, you mostly have two patients at a time, and you are pressed to get them recovered and transferred to the floor, or discharged home within a certain amount of time. Your hold up in PACU can hold up the OR, and hold up the docs, and no-one likes to be held up. I've come to just accept that I will have at least one bad day in PACU, BUT will have good days as well.
Oh, and you need to be thick skinned!
