Ankle blocks are routinely indicated for surgical anesthesia and postoperative analgesia of procedures involving the foot. Traditionally, ankle blocks have been performed by relying on landmark identification of nerves. The literature regarding the performance and efficacy of ankle blocks is inconsistent. ⋯ The ability to identify peripheral nerves, view needle movements in real-time, and observe the spread of local anesthetic has been shown to result in greater block efficacy, even with reduced volumes of local anesthetic. Additionally, ultrasound imaging gives the provider the option to perform regional anesthesia in specific patient populations not considered possible when using landmark technique. Despite the limited literature on ultrasound-guided ankle blocks, outcome metrics seem to be consistent with those of other peripheral nerve blocks performed using this technology.

Postoperative nausea and vomiting is one of the most common complications affecting surgical patients. The glucocorticoid dexamethasone is often used for the prevention of postoperative nausea and vomiting. ⋯ Although the majority of the literature reviewed found no association between single-dose intraoperative dexamethasone and an increase in surgical site infections, the need for a large-scale randomized controlled trial is consistently mentioned. Prudent clinicians should always use the most current evidence with their best clinical judgment when making medication decisions for their patients.

Use of opioids to provide adequate perioperative analgesia often leads to respiratory depression, nausea, vomiting, urinary retention, pruritus, and opioid-induced hyperalgesia, with the potential to increase length of stay in the hospital. In an effort to reduce perioperative opioid administration yet provide appropriate pain relief, researchers began to study the use of esmolol beyond its well-known cardiovascular effects. Perioperative esmolol has been shown to reduce anesthetic requirements, decrease perioperative opioid use, decrease the incidence of postoperative nausea and vomiting, lead to an earlier discharge, and increase patient satisfaction. This article provides a review of the literature on the use of esmolol as an adjunct for perioperative analgesia and anesthesia.

Perioperative outcomes research using anesthesia information management systems (AIMS) is an emerging research method that has not been comprehensively reviewed. This review reports an initial analysis of the use of AIMS for perioperative patient outcomes research from articles published between January 1980 and January 2013. ⋯ Use of AIMS for perioperative outcomes research can address clinically relevant topics that traditional research methods have been unable to adequately address, mainly because of the innate challenges presented by perioperative anesthesia practice. It is expected that perioperative effectiveness and outcomes research using large AIMS databases will be more widely embraced in the future to generate useful evidence and knowledge to improve anesthesia care.

Noise is a health hazard and a source of stress, and it impairs concentration and communication. Since 1960, hospital noise levels have risen around the world. Nowhere in the healthcare setting is noise more prevalent than in the operating room (OR). ⋯ The World Health Organization has recognized environmental noise as harmful pollution that causesadverse effects on health. Although noise in the OR is unavoidable, music is a choice. The purpose of this literature review is to provide further insight into the ramifications of the presence of music in the OR, evaluate its appropriateness in relation to care and safety for the patient and staff, and provide information for future research.
