Yes. Our 25 bed ICU was created back in the 70's specifically for recovering patients from anesthesia following thoracic (CABG/valves/thoracic aneurysms) and vascular surgery including heart, lung and heart/lung transplants. We also recover general surgery/trauma patients as overflow from the 24 bed med/surg/trauma ICU.
Like mattsmom81 stated, the patient is rolled into the ICU from the OR suite by the surgeons and anesthesia and handed off directly to us, the RNs. They bypass any recovery room associated with the OR.
Whether these patients are 1:1 depend on how their surgery went. 99% of our post-op patients come back intubated and still under the effects of anesthesia. If it was a complicated or lengthy case, or if they come back with a balloon pump, VAD, ECMO, or are bleeding they're defintely 1:1. Sometimes these patients can need 2-3 RNs (2 at the bedside and 1 charting) to stabalize them. It can get very hairy especially when they're bleeding.
We also do open chest on the unit when the patient is too unstable to safely move back to the OR. Occasionally there can be 5-6 people in the room with one very sick patient...RN's, an anesthesiologist, surgeon, and CNS (also an OR tech if we're opening). In the 4 years I've been in this ICU, I don't think I've ever seen a patient roll in with neuromuscular blockade agents running as a gtt, but we do use those drugs for other reasons..ARDS, etc.
If the case was a routine CABG or uncomplicated transplant or vascular, the RN receives the fresh post-op with another stable patient already assigned. This assignment is busy for the first couple of hours, but the skill level of the typical RN on this unit is amazing and we do it, and do it well, all the time.
At no time on our unit is one RN responsible for more than 2 patients, even on breaks. It's been like this forever not only due to the acuity of our patients, but because it's also the law. Our unit staffs for this by having 1-3 RN floats (depending on the unit's census) to cover breaks, and lend a hand where needed.
As far as when the post-op anesthesia period ends, I guess it depends on the individual patient and the preference of the individual attending physician. I guess the anesthesia period, for me, ends when I hear bowel sounds.
Many times we will keep patients sedated with propofol (and pain meds) or fentanyl/versed for an extended period of time. With routine, uncomplicated cases we have a standing order to extubate within 6-8 hours depending on how the patient wakes up from anesthesia. As a matter of fact, all of our fresh post-op orders are standardized with additional orders for the individual patient. We are very autonomous.
We've had some routine heart transplants awake, alert and talking after only a total of 7-8 hours, including the surgery itself! It's amazing!
I don't know what the AACN's guidelines are. I'm sure there's plenty of info out there if you do a search.
