Several decades ago, the analgesic properties of buprenorphine were discovered. Its approval for the use as an agent for the treatment of opioid abuse has led to increasing numbers of patients presenting for surgery on buprenorphine. This article describes the challenges, advantages, and disadvantages of the use of buprenorphine as an analgesic for postoperative pain in patients with and without preoperative maintenance therapy.

Over the last several decades, the average age of patients has steadily increased, whereas the use of general anesthesia and deep sedation has grown largely outside the operating room environment. Currently available general anesthetics and delivery models represent limitations in addressing these trends. At the same time, research has tremendously expanded the knowledge of how general anesthetics produce their beneficial effects and also revealed evidence of previously unappreciated general anesthetic toxicities. The goal of this review is to highlight these important developments and describe translational research on new general anesthetics with the potential to improve and reshape clinical care.

ReviewAdvances in perioperative pain management: use of medications with dual analgesic mechanisms, tramadol & tapentadol.
Recovery from ambulatory surgical procedures can be limited by postoperative pain. Inadequate analgesia may delay or prevent patient discharge and can result in readmission. More frequently, postoperative pain produces discomfort and interrupts sleep, contributing to postoperative fatigue. ⋯ In contrast to pure opioid agonists, both drugs are believed to have lower risks of respiratory depression, tolerance, and dependence. The Food and Drug Administration has approved both drugs for the treatment of moderate-to-severe acute pain in adults. This article provides an evidence-based account of the role of tramadol and tapentadol in modern clinical practice.

ReviewApplications of ultrasonography in ENT: airway assessment and nerve blockade.
This article presents a comprehensive narrative review of the published literature relating to ultrasound imaging relevant to anesthesia for ear, nose, and throat (ENT) surgery. The review comprises 2 main subject areas: the use of ultrasonography related to assessment and management of the airway, and the use of ultrasonography related to nerve blockade for ENT surgery. The relevant sonoanatomy and suitable probe placement are illustrated in relation to applicable regional anatomy (they are not discussed). The possible value of the use of ultrasonography to improve existing clinical practice in these areas is explored.

ReviewLaser surgery and fire hazards in ear, nose, and throat surgeries.
Operating room fires are rare but can be devastating. These fires can occur during almost any surgical procedure but are more likely during airway surgery, during head and neck surgery, and if volatile flammable liquids are used. Each team in the operating room (ie, anesthesia, surgery, and nursing) has special expertise and responsibility in preventing and responding to a fire. Fires can be prevented by ongoing education and an interdisciplinary discussion of risks and responsibilities prior to each high-risk case.
