Understanding conscious sedation in the operating room.

Conscious sedation is an appropriate choice for patients who do not require a general anesthetic, but rather need sedation to alleviate anxiety, minimize the discomfort of less invasive surgical procedures, or even to tolerate a regional or local anesthetic. New pharmaceutical agents, with their short half lives, provide amnesia, analgesia, and sedation quite safely. This concept, combined with standardized and controlled safety monitoring, offers an anesthetic alternative quite acceptable to many patients and health care providers. Standards and guidelines have been extensively developed by the American Society of Anesthesiologists, and the American Association of Nurse Anesthetists, to set forth a practice for all providers that will promote patient safety and provider vigilance (AANA, 1998). The purpose of this article is to review the process of conscious sedation.
