The nurse plays a very important role in administering procedural sedation and monitoring the patient receiving it. Receiving specialized training and adhering to strict institutional standards helps to keep patients safe. The nurse's primary responsibility during procedural sedation is exclusively to that patient. The American Association of Nurse Anesthetists (AANA) suggests that the registered nurse managing and monitoring the patient receiving sedation and analgesia should have no other responsibilities during the procedure. One of the most important things the nurse can do to prevent complications is to avoid overmedication. Intravenous sedative and analgesic drugs should be given in small, incremental doses that are titrated to the desired end point of sedation and analgesia. The American Society of Anesthesiologists (ASA) agrees that continued observation, monitoring, and predetermined discharge criteria decrease the likelihood of adverse outcomes for both moderate and deep sedation.
