Review Meta AnalysisNon-pharmacological interventions for assisting the induction of anaesthesia in children.
Induction of general anaesthesia can be distressing for children. Non-pharmacological methods for reducing anxiety and improving co-operation may avoid the adverse effects of preoperative sedation. ⋯ This review shows that the presence of parents during induction of general anaesthesia does not reduce their child's anxiety. Promising non-pharmacological interventions such as parental acupuncture; clown doctors; hypnotherapy; low sensory stimulation; and hand-held video games needs to be investigated further.

ReviewTeaching off-pump coronary artery bypass surgery.
Off-pump coronary artery revascularization requires a unique skill set and a different conduct of operation compared with on-pump coronary artery bypass. Not only must the surgeon perform anastomoses on the beating heart, but he/she must understand the hemodynamic consequences of cardiac positioning and stabilization, the effects of regional ischemia on hemodynamic function, contractility, and arrhythmias, and the importance of anesthesia and grafting sequence given variants of anatomy and clinical conditions. Given these differences, the ability to teach off-pump coronary artery bypass to residents and surgeons places unique demands on the teaching surgeon. In this article, we review the available literature about the safety and efficacy of teaching off-pump coronary artery bypass to residents, discuss the fundamentals for training residents, and review the future of simulation and new training paradigms and the impact this will have on current training methods.

Intraoperative hypoxaemia and postoperative respiratory complications remain the challenges of modern anaesthetic practice. Anaesthesia causes both depression of respiratory centres and profound changes of respiratory mechanics. ⋯ In this review, we briefly describe the mechanisms responsible for the impairment of intraoperative gas exchange and provide guidelines to prevent or manage hypoxaemia. Moreover, we discuss several aspects of mechanical ventilation that can be employed to improve patients' outcome.

This article discusses the issues of morbidity and mortality associated with deep sedation and general anesthesia specifically in the dental office-based setting for patients with special needs (PSN). A focused review of a particular environment and patient population was challenging as it was difficult to identify articles that discuss the unique scope of this subject. During the review of the literature, no article was identified that discussed this exact topic. ⋯ In addition, an analysis of the author's practice over a 4-year period is discussed in an effort to present relevant data per the scope of this article. After reviewing the literature and the author's clinical practice, it appears that the incidence of mortality for PSN in the dental office-based setting is minimal and the incidence of morbidity for this same population is limited to relatively minor events. Ultimately, it was concluded that the delivery of general anesthesia for PSN in the dental office-based setting can be considered a very safe and successful procedure.

ReviewThermal management during anaesthesia and thermoregulation standards for the prevention of inadvertent perioperative hypothermia.
Incidence of inadvertent perioperative hypothermia is still high, and thus thermoregulatory standards are warranted. This review summarizes current evidence of thermal management during anaesthesia, referring to recognized clinical queries (temperature measurement, definition of hypothermia, risk factors, warming methods, implementation strategies). Body temperature is a vital sign, and 37 degrees C is the mean core temperature of a healthy human. ⋯ The patient's body temperature should be above 36 degrees C before induction of anaesthesia, and should be measured continuously throughout surgery. Active warming should be applied intraoperatively. Postoperative patient temperature and outcomes should be evaluated.
