650—29.1 (153) Definitions. For the purpose of these rules, relative to the administration of deep sedation/general anesthesia, moderate sedation, minimal sedation, and nitrous oxide inhalation analgesia by licensed dentists, the following definitions shall apply:
“Antianxiety premedication” means minimal sedation. A dentist providing minimal sedation must meet the requirements of rule 650—29.7(153).
“ASA” refers to the American Society of Anesthesiologists Patient Physical Status Classification System. Category 1 means normal healthy patients, and category 2 means patients with mild systemic disease. Category 3 means patients with moderate systemic disease, and category 4 means patients with severe systemic disease that is a constant threat to life.
“Conscious sedation” means moderate sedation.
“Deep sedation/general anesthesia” is a controlled state of unconsciousness, produced by a pharmacologic agent, accompanied by a partial or complete loss of protective reflexes, including inability to independently maintain an airway and respond purposefully to physical stimulation or verbal command.
“Maximum recommended dose (MRD)” means the maximum FDA-recommended dose of a drug as printed in FDA-approved labeling for unmonitored home use.
“Minimal sedation” means a minimally depressed level of consciousness, produced by a pharmacological method, that retains the patient’s ability to independently and continuously maintain an airway and respond normally to tactile stimulation and verbal command. Although cognitive function and coordination may be modestly impaired, ventilatory and cardiovascular functions are unaffected. The term “minimal sedation” also means “antianxiety premedication” or “anxiolysis.” A dentist providing minimal sedation shall meet the requirements of rule 650—29.7(153).
“Moderate sedation” means a drug-induced depression of consciousness, either by enteral or parenteral means, during which patients respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation. No interventions are required to maintain a patent airway and spontaneous ventilation is adequate. Cardiovascular function is usually maintained. Prior to January 1, 2010, moderate sedation was referred to as conscious sedation.
“Monitoring nitrous oxide inhalation analgesia” means continually observing the patient receiving nitrous oxide and recognizing and notifying the dentist of any adverse reactions or complications.
“Nitrous oxide inhalation analgesia” refers to the administration by inhalation of a combination of nitrous oxide and oxygen producing an altered level of consciousness that retains the patient’s ability to independently and continuously maintain an airway and respond appropriately to physical stimulation or verbal command.
“Pediatric” means patients aged 12 or under.
