Course Description:

The Maryland State Board of Dental Examiners (MSBDE) recently adopted rules which allow properly-trained registered dental hygienists to monitor nitrous oxide sedation during dental hygiene-related procedures. This course fulfills and exceeds MSBDE educational requirements for registered dental hygienists.

The first portion of this course will consist of four hours of lecture, followed by a written examination. The course will include the history, physiological and pharmacologic effects of nitrous oxide sedation; definitions and descriptions of the physiological and psychological aspects of pain and anxiety;  concepts and management of pain and anxiety; indications and contraindications; anatomy and physiology of respiration; medical assessment of a patient prior to administration of nitrous oxide; armamentarium and equipment; moderate sedation, deep sedation and general anesthesia versus nitrous oxide; pharmacological and physiological effects of nitrous oxide, including drug interactions; a description of the distinction between consious and unconscious state; monitoring and evaluating a patient to whom nitrous oxide has been administered; recognition and management of complications and medical emergencies; chart documentation; occupations exposure and toxicity; preventing, recognizing and managing possible complications of inhalation sedation.

Attendees will also participate in a two-hour practical demonstration and proficiency testing. Course work includes readings and a homework assignment. Course participants must pass the written and proficiency exams with a 75 or greater.

Course Objectives:

Upon completion of this course, the participants should be able to:

  • Recognize patient indications for nitrous oxide sedation 
  • Describe the basic physiology of the human respiratory system 
  • Describe the pharmacological effects of oxygen and nitrous oxide, including drug interactions
  • Assess and manage pain and anxiety
  • Assess a patient prior to administration of nitrous oxide
  • Describe the stages of anesthesia, and the planes of analgesia, including signs and symptoms of each
  • Identify specific clinical symptoms associated with each of the planes of analgesia while monitoring nitrous oxide
  • List the steps in administering nitrous oxide sedation
  • Calculate the total liters of flow per minute
  • Recognize and manage complications and medical emergencies
  • Properly record chart entries including administration of nitrous oxide sedation
  • List health hazards associated with nitrous oxide toxicity
