Over the past several decades, there have been evolutionary changes in both surgery and anesthesia. Newer anesthetics have excellent safety profiles and are associated with fewer hemodynamic side effects and rapid elimination from the body. Innovative surgical techniques are less invasive and cause less perioperative patient pain. ⋯ Because of the remote nature of the private surgeon's office, the proper selection of both patient and procedure to be performed is of utmost importance. It is likewise imperative that the practitioner assures that the patient does not experience excessive postoperative pain and/or nausea and vomiting. It is of the utmost importance that the practicing anesthesiologist assure that every location in which procedures and surgeries are performed is a safe anesthetizing location.

Anemia is common in critically ill patients. Although the goal of transfusion of red blood cells is to increase oxygen-carrying capacity, there are contradictory results about whether red blood cell transfusion to treat moderate anemia (e.g., hemoglobin 7-10 g/dL) improves tissue oxygenation or changes outcomes. Whereas increasing levels of anemia eventually lead to a level of critical oxygen delivery, increased cardiac output and oxygen extraction are homeostatic mechanisms the body uses to prevent a state of dysoxia in the setting of diminished oxygen delivery due to anemia. ⋯ These studies have generally shown increases in near-infrared spectroscopy derived measurements of tissue oxygenation following transfusion. Studies evaluating the effect of transfusion on the microcirculation have shown that transfusion increases the functional capillary density. This article will review fundamental aspects of oxygen delivery and extraction, and the effects of red blood cell transfusion on tissue oxygenation as well as the microcirculation.

In a complicated and specialized population, such as patients undergoing cardiac and major vascular procedures, patients, clinicians, and hospitals may be best served and resources conserved with a specialized preanesthesia clinic. A specialized preanesthesia clinic for cardiac and major vascular procedures has a focused staff usually consisting of practitioners with cardiac and major vascular surgical care experience designed to address the patient evaluation, the information gathering, the necessary consultations, the required testing, and specific needs for the day of cardiac and major vascular surgery. ⋯ Resident trainee education can also be enhanced by a specialized preanesthesia clinic for cardiac and major vascular rotations. The ultimate goal of a specialized preanesthesia clinic is to ensure a safe and efficient perioperative cardiac and major vascular surgical experience in complicated patients undergoing complex procedures.

This report reviews and critically evaluates the development of 3 movements in healthcare that have had a profound impact on changes occurring at all levels of medical education: patient safety, healthcare simulation, and competency-based education (exemplified by the Accreditation Council for Graduate Medical Education). The authors performed a critical and selective review of the literature from 1999 to 2011 to identify uses of simulation to address patient-safety issues aligned according to the Accreditation Council for Graduate Medical Education 6 core competencies: (1) patient care; (2) medical knowledge; (3) interpersonal and communication skills; (4) professionalism; (5) practice-based learning; and (6) systems-based practice. ⋯ Simulation-based learning can lead to positive patient outcomes and reduction of medical errors particularly when used for individual skills. However, particular attention needs to be placed on the organizational context in which it is implemented if improvements in practice-based learning and systems-based practice are to be realized.

Reduction in retained surgical items is an important part of any operating room patient-safety effort. Any item used in an operation can result in a retained surgical item, but sponges are the most frequent and the abdomen is the most common location. ⋯ This review will examine counting, teamwork, radiography, and new technology as methods used to prevent retained surgical items. Even though none of these techniques individually is likely to completely prevent retained surgical items, when used together the numbers can be reduced.
