Because propofol is the sedative preferred by gastroenterologists, we focus this review on gastroenterologist-directed propofol sedation, provide simulations of the respiratory depressant effect of different dosing protocols and give a perspective on future developments in computer-assisted sedation techniques. ⋯ Propofol use by gastroenterologists may be well tolerated if appropriate patient selection, staff training, monitoring and low-dose sedation protocols are applied.

Opioid administration is a mainstay of anesthetic practice both for treating acute perioperative pain and for chronic pain syndromes. Growing pharmacogenetic data make it evident that many opiate-related phenomena are influenced by genetics. Genetic variation may significantly affect opiate absorption, distribution, metabolism, excretion and toxicity. We provide a current review of opiate pharmacogenetics. ⋯ Knowledge of genetic factors that affect opioid efficacy, metabolism, and side effects have the potential for personalizing both acute and chronic pain management, and for designing more effective opiate pain medications with lower side effect profiles.

We review the efficacy and safety of gantacurium and AV002, two novel, investigational fumarate-based nondepolarizing neuromuscular blockers, as well as sugammadex and cysteine, two novel reversal drugs that have no acetylcholinesterase inhibition properties. ⋯ In a multicenter phase-2 randomized controlled study in the European Union, the efficacy and safety of gantacurium were evaluated, but results have not yet been published. Sugammadex is currently available in the European Union, but the United States Food and Drug Administration has had concerns about its safety (hypersensitivity and allergic reactions) and has asked for additional safety data. It is hoped that the widespread use of sugammadex in the European Union will provide additional information.

Safety, quality, and patient satisfaction are not only defined by the incidences of serious adverse events but also include postoperative outcomes such as postdischarge nausea and vomiting (PDNV). PDNV has a high impact on patient recovery and may influence the cost-effectiveness of office-based surgical procedures. This article reviews the incidences and risk factors for PDNV as well as medications and concepts for prophylaxis and treatment. ⋯ PDNV is an under-recognized problem after outpatient anesthesia. Valid data for the incidence and the best treatment of PDNV after office-based anesthesia are rare. For safety, quality, and patient satisfaction, further research is needed to develop a prediction model to better identify patients at risk for PDNV in order to direct antiemetic prophylaxis for ambulatory patients undergoing office-based anesthesia.

Toxicity concerns and awareness during anesthesia issues continue to concern pediatric anesthesiologists. Most developmental pharmacokinetic, pharmacodynamic and pharmacogenomic changes occur within the first year of life. Understanding these early changes can improve drug use in this cohort. ⋯ Mechanistic models create a framework for the study of pharmacokinetic changes in infancy. Understanding these changes allows a target concentration approach to therapy and potential for reduced toxicity. The target concentration may be undefined because of a paucity of effect measures.
