Conscious sedation or nitrous oxide sedation is the minimally depressed state of consciousness where a person is able to retain his vital protective reflexes and can maintain the airway on his own. This means that he is able to speak and breathe but his pain threshold increases. Most people are somewhat apprehensive about dental surgery; conscious sedation eases some of the apprehension.

What a patient can expect
For a person under oral sedation, the feeling of warmth or tingling sensation in the hands and toes are the initial symptoms that appear. A person feels light and a floating sensation prevails. Many patients describe it as a drunken feeling, and though the dentist still has to use the local anesthetic injection, the anxiety about it comes down and the pain threshold becomes high. The patient can interact with the dentist and the dentist can comfort the patient throughout the duration of the treatment.
Nitrous oxide is given in a combination with oxygen and the titration is done slowly till the maximum dose of nitrous oxide is 40%. At the end of the treatment, 100% oxygen is given for 5 minutes and unlike general anesthesia, here the patient will be up and about in no time.
Why dentists should study oral sedation?
Using chair side sedation can help dentists with anxious patients, and especially with pediatric patients, where treatment becomes cumbersome just because of the patients’ tantrums. Many oral surgical procedures can lead to anxiety in patients and hence cause syncope, which is the most common medical emergency in dental practice. To avoid this, a thorough knowledge of the procedure, indications and the contraindications is indispensable.
Learning about the contraindications of oral sedation is of prime importance for the safety of the patient and the dentist’s career, and hence a detailed study course of sedation is required. Patients with any kind of respiratory problems or those with hypothyroidism should not be considered for oral sedation with nitrous oxide.
What do you learn?
American society of anesthesiologists has given a set of guidelines for the safe practice of conscious sedation for dentists, but proper hands-on training is required. This procedure is a boon to dental practice, as the gas inhalation is done by the nasal route, so the oral cavity is free from any tubes (as in GA) to work. The apparatus required is inexpensive and portable, and the nasal masks are available in different sizes for pediatric and adult patients also.
