They are both great jobs. Our hospital ambulatory surgery center and endoscopy center was combined into one unit. I had been a nurse for 20 years before ambulatory nursing, however I had been in administration for 5 years so was really nervous about what skills I had lost.
Honestly it is really pretty easy. The patient has been seen by his primary MD, his surgeon or gastroenterologist, and gets assessed by the anesthesiologist. So they do not even enter the ambulatory surgery center if these doctors think they are not basically healthy enough to not need to be admitted to a hospital. So you are taking care of healthy patients for relatively minor procedures.
It can be very fast paced, the center makes it money by doing a lot of procedures every day.
Paperwork and speed can take priority over patient assessments. Of course they must be assessed but remember they have already been deemed healthy. You will be doing very limited patient assessments.
In surgery the unconscious patient is giving up all their care to us. You must be their protector, are they signing the correct consent for the correct body part. When did they eat, are the allergic,.......the OR or pre-op check list is critical. Once the patient is unconscious it is too late to discover that they did eat, or are allergic to such and such.
You may need to start IV's, but in some places anesthesiologists do this.
There is tons more to know, consider. Look over PACU nursing for some ideas about PACU nursing. But realize SOME of the PACU responses are referring to acute care major surgery PACU nursing. What they say may not apply at all to ambulatory PACU nursing.
You will probably need ACLS.
