ReviewImproving outcomes in ambulatory anesthesia by identifying high risk patients.
Currently, outcome data in ambulatory anesthesia are somewhat limited though results are quite good with low reported rates of mortality and major morbidity. As patient comorbidities and surgical invasiveness increase, identifying those patients at higher risk will help to focus quality improvement energy and research where most effective. Better data collection and analysis will refine patient and procedure selection and improve outcomes going forward. ⋯ Identifying high-risk ambulatory patients can help facilitate development of a strategy to triage these patients, optimize their conditions prior to surgery, and manage their care and disposition postoperatively. Inpatient surgery or admission should be considered for higher risk patients having high invasive surgery.

ReviewEcho-guided invasive pain therapy: indications and limitations.
The purposes of this review are to summarize the advantages and limitations of ultrasound-guided pain interventions, and to illustrate those interventions with peripheral, axial and musculoskeletal pain procedures. ⋯ Pain intervention under ultrasound guidance is particularly valuable in peripheral and musculoskeletal procedures. There is growing interest of its application in cervical spine and sacroiliac joint. More outcome studies are required in the future to make ultrasound-guided pain intervention as the established procedure.

ReviewNeuromonitoring in the ambulatory anesthesia setting: a pro-con discussion.
Various neurologically focused monitoring modalities such as processed electroencephalography (pEEG), tissue/brain oxygenation monitors (SbO2), and even somatosensory evoked responses have been suggested as having the potential to improve the well tolerated and effective delivery of care in the setting of outpatient surgery. The present article will discuss the pros and cons of such monitors in this environment. ⋯ The use of advanced neuromonitoring techniques (primarily pEEG) may be considered reasonable in two instances: for the prevention of intraoperative awareness during the administration of total intravenous anesthesia coupled with the use of a neuromuscular blocking drug, and for the prevention of relative drug overdose (and possibly postoperative delirium) in the elderly.

ReviewRebound pain after regional anesthesia in the ambulatory patient.
Regional anesthesia is popular in ambulatory setting allowing safe and fast recovery. The problem of 'rebound pain', that is very severe pain when peripheral nerve block (PNB) wears off represents a clinically relevant problem and a cause of increased healthcare resource utilization. This review tries to make the point on a not so rare, unwanted and often neglected side effect of PNB. ⋯ Patients' report of excruciating pain and major distress when PNB wears off questions the quality of current anesthesia practice in ambulatory setting. Rebound pain unanswered questions are challenging in the area of perioperative medicine.

The increasing number of procedures done in the ambulatory surgical setting necessitates the need for analgesic modalities that enable the management of postsurgical pain with fast onset, predictable duration of action, and minimal need for management of undesirable side-effects. ⋯ Local anesthetics, opioids, and NSAIDS are the mainstay of multimodal analgesic management, and as such, improving their efficacy in the ambulatory surgical setting remains the primary focus. However, as knowledge of the modulating pathways involved in transduction of pain increases, newer agents that utilize this knowledge are also becoming more widely available.
