title: Sedation, analgesia, and local anesthesia: a review for general and interventional radiologists.
abstract: Radiologists, like other physicians, need to know how to use sedatives, analgesics, and local anesthetics; however, their exposure to patients requiring discomfort control is limited, not just during residency but also in postgraduate practice. The purpose of this article is to provide a reference guide for radiologists who need pertinent and ready information on discomfort control. The authors discuss policies and standards that the Joint Commission has established for sedation providers; also discussed are the clinical pharmacology and dosage recommendations for the sedative, analgesic, anesthetic, and reversal agents that radiologists are most likely to use. Monitored anesthesia care and patient-controlled analgesia pumps, and in what circumstances they may be appropriate, are discussed. Anesthesia consultations are not uncommon when a nonanesthesiologist needs either of these services. Stiff chest syndrome, serotonin release syndrome, and systemic toxicity due to local anesthesia, all life-threatening conditions that sedation and analgesia providers may encounter, are discussed. The causes of these conditions and their necessary treatments are included in the discussion, along with cases in which a nonanesthesiologist may need an anesthesia consultation. It is important to understand that the control of pain and anxiety are not mutually exclusive but can occur either separately or together; when an agent that controls anxiety and an agent that controls pain are given together, the overall effect is synergistic. It is also important to understand the concept of multimodal analgesia; this is the use of opioids and nonopioids together to take full advantage of the analgesic effects of each component while minimizing potential side effects. Radiologists are fully capable of providing effective and safe pain control on their own and with the assistance of an anesthesiologist.
