Ambulatory anesthesia is used for surgical procedures where the patient does not need to stay overnight in the hospital. The same anesthetics that are used in the operating room setting are used in the ambulatory setting, including general, regional and local anesthetics. Sedation anesthetics are also given in the ambulatory setting. This issue will cover best practices and procedures for perioperative care, regional anesthesia, pediatric anesthesia, administering office anesthesia, and more.

As with all anesthetics, perioperative management may be divided into preoperative, intraoperative, and postoperative management. Preoperatively, one of the things that makes the practice of ambulatory anesthesia unique is the appropriate selection of patients. Most ambulatory anesthesiologists have encountered the patient who is deemed an inappropriate candidate because of his or her comorbidities. A question often asked of experienced ambulatory practitioners is whether there is a checklist or the like that can be applied to determine appropriate patients for the outpatient setting. This checklist might include answers to questions such as, “what is the maximum body mass index; should I care for a patient with a difficult airway; is a spinal anesthetic appropriate; are patients with an implantable cardiac defibrillator (ICD) acceptable?” There is potential value in creating such a checklist for the anesthesia provider and the proceduralist, but there are potential problems as well. To uniformly refuse service to all individuals with a given condition likely unduly limits access and does not allow the facility to take full advantage of its potential. Rather than a checklist that limits itself to just one aspect, it is best to recognize that it is not just the patient selection process that is important, but one must also consider the providers, the procedure, and the facility (place), taking into account the comorbidities of the patient, the skillsets of and access to providers, the procedure itself, and the availability of equipment in, and the location of, the facility. Facilities (place) where ambulatory anesthesia is practiced include hospitals, where there can be a designated suite of operating rooms for these cases or where they can be interspersed throughout the larger operating room suite. Alternatively, there can be a separate dedicated building where ambulatory procedures are performed, referred to as an “on-campus” setting. Outpatient procedures can also be performed in a freestanding surgicenter located some distance away from a major hospital. The final location is that of the office, which is probably the ne plus ultra of ambulatory anesthesia. Obviously, each of these settings has its advantages and limitations in terms of its ability to care for the more complex patient because of the available personnel and equipment and the proximity to other facilities for support or even transfer. The number of providers and their level of training also impact the selection process. The skillset of the ancillary staff is important, especially when it comes to postanesthesia care. Having a receptionist with no medical training who also serves as the individual who monitors the patient after the procedure limits the complexity of both the procedure and the anesthetic technique. Having two trained and capable postanesthesia care unit nurses may mean that more complex procedures and anesthetics may be performed. Having an anesthesia technician may provide more equipment support so more sophisticated techniques (eg, fiberoptic bronchoscopy) may be available. Thus, the caliber and quantity of primary and support personnel influence the selection process. The procedure is clearly an important part of the equation. In the 1990s, criteria for an acceptable procedure included minimal blood loss/fluid shift, duration of less than 90 minutes with simple equipment, minimal postoperative care, and minimal pain able to be treated with oral medications.1 In the twenty-first century, the requirement is merely that the patient be able to go home the same day or, in some settings, within 23 hours. There really are no hard and fast rules that can be applied to distinguish an ambulatory procedure from an inpatient procedure other than the ability to safely go home the same day. When an anesthesiologist can provide an anesthetic from which the patient should be able to recover within a few hours, the limiting feature becomes the postoperative care associated with the procedure. The final factor in the equation is the patient. Some may believe that only American Society of Anesthesiologists physical status class 1 or 2 patients should be cared for in an ambulatory setting, but this fails to take into account the impact of the place, the procedure, and the personnel. For example, a patient with obstructive sleep apnea can safely receive a lower extremity regional anesthetic with intravenous sedation and analgesia in many ambulatory facilities. There is little if any evidence that an otherwise healthy patient with a body mass index above a certain level is at increased risk for an ambulatory procedure, but there is the caveat that the operative table must be able to support the weight. While some may be loathe to care for a patient with an ICD in an office-based practice or a surgicenter, performing a procedure for this patient in an on-campus or integrated facility may be entirely appropriate. Thus, one must look at a variety of factors and integrate them into a meaningful whole to determine the appropriateness of admission to an ambulatory setting. Figs. 1 and 2 illustrate this principle, where a patient with an ICD is acceptable in an on-campus setting but not in an office setting.

The defining aspect of an ambulatory anesthetic is the patient’s ability to safely and comfortably leave the facility the same day. There are at least four sequelae to consider that are dependent on the anesthesiologist’s preoperative, intraoperative, and postoperative management. While these will be dealt with in greater detail in other articles, they can be summarized to provide an overall recommendation for perioperative management. These “barriers” to discharge include pain, postoperative nausea and vomiting, excessive sedation, and significant pathophysiologic derangements. Pain is regarded as the most common and most important adverse postoperative outcome.2–4 Multimodal therapy using low-dose opioids, nonsteroidal anti-inflammatory drugs, and regional anesthesia serves to mitigate this. Postoperative nausea and vomiting can likely be regarded as the second most significant impediment and is also amenable to a multimodal approach, both to avoid the problem and to treat it. Excessive sedation also results in delayed discharge,5 so preoperative and intraoperative sedative-hypnotics and intraoperative and postoperative opioids should be used judiciously. Morbid events, such as cardiac ischemia, hyperglycemia, cerebral vascular accident, or persistent hypotension, may also delay discharge, but the preoperative selection process and overall perioperative management should minimize this. Managing to avoid the sequelae of these comorbidities and other “complications” is of paramount importance to ensure a safe and timely discharge to home. For this issue of Anesthesiology Clinics, our authors have detailed many of the clinical and logistical perioperative ambulatory anesthesia concerns that may lead to suboptimal outcomes and offer ways to manage them. We have also included articles on the administrative aspect of the practice of ambulatory anesthesia, since quite often it is the anesthesiologist who serves as the medical director and administrative go-to person in the facility. We finish with a glimpse of the future, including articles on the electronic medical record and the application of quality assurance registries in the ambulatory domain. We hope to provide a relatively broad overview of the practice of ambulatory anesthesia while also yielding a deeper understanding of some of the more common or pressing issues. Summary
The bottom line is that proper preoperative selection and preparation and the application of certain intraoperative techniques will best ensure that those who walk in to an ambulatory surgery facility will be able to walk out the same day. References
