Outpatient plastic surgery is growing around the world. This industry faces unique challenges in terms of patient selection and standards of practice to ensure safety and cost-effectiveness. This review will highlight information about anesthesia practice for outpatient cosmetic surgery in Brazil, especially regarding regulation, legislation, and medical tourism. ⋯ Brazil is one of the world's leaders in cosmetic surgery. Strong legislation governing outpatient facilities and continued development of accrediting standards for healthcare facilities are indications of a commitment to patient safety and high quality of care. Although the market for medical tourism in this country is high, there are still barriers to overcome before Brazil reaches its full potential in this industry.

ReviewNew insights in the systemic and molecular underpinnings of general anesthetic actions mediated by γ-aminobutyric acid A receptors.
The review highlights novel insights into the role of γ-aminobutyric acid A (GABAA) receptors in mediating clinically relevant actions of anesthetic agents. ⋯ Identification of the molecular and cellular substrates involved in anesthesia and insights into disease and drug-induced alterations in the expression patterns of GABAA receptors in the central nervous system are emphasizing the need for individualized anesthesia care. Introducing neuroactive steroids into clinical anesthesia is expected to reduce cardiovascular and respiratory side-effects.

ReviewDo we really need sugammadex as an antagonist of muscle relaxants in anesthesia?
Sugammadex is a selective relaxant-binding agent that is designed to encapsulate rocuronium and chemically similar steroidal muscle relaxants such as vecuronium. This review summarizes recent information on the use of sugammadex in clinical practice. ⋯ Sugammadex offers a significantly faster and more predictable recovery profile than neostigmine. It is now possible to reverse rapidly and efficiently any level of neuromuscular blockade and to avoid the risk of adverse events because of residual paralysis such as critical respiratory events during recovery from anesthesia.

ReviewLevosimendan: new indications and evidence for reduction in perioperative mortality?
In the last years, the perioperative use of levosimendan in cardiac surgery patients is spreading. Moreover, newer indications have been suggested such as the treatment of sepsis-associated myocardial dysfunction. In the present review, we discuss the most recent evidences in these settings. ⋯ Although a strong rationale likely exists to use levosimendan in the setting of perioperative and critical care medicine, evidence mainly comes from small and often poor-quality randomized clinical trials, whose results acquire significance only when pooled in meta-analyses. Moreover, some aspects related to which subgroups of patients may derive the most benefits from receiving levosimendan, to the optimal timing of administration, and to the potential adverse effects need to be further clarified. Important insights will be hopefully provided soon by the several large multicenter investigations which are currently ongoing.

ReviewOpioids and tumour metastasis: does the choice of the anesthetic-analgesic technique influence outcome after cancer surgery?
Cancer is now one of the leading causes of death worldwide, and excisional surgery is an essential treatment for the four most common adult cancers. Opioids remain the most commonly prescribed analgesics in the perioperative period of cancer surgery, yet the question of whether opioids could influence recurrence or metastasis remains unanswered. ⋯ Prospective randomized trials are required to investigate this important topic further. Several are currently ongoing. Until the results of these are available for scrutiny, there is currently insufficient evidence to recommend any changes to current clinical practice. Opioids continue to play an important role in the perioperative period.
