Providing adequate sedation and analgesia is an Integral part of the practice to deal with anxiety. Selected patients may not require any sedation for certain basic procedures. However, a few dental procedures are performed under moderate sedation and analgesia, which is also known as “conscious sedation.” At this level of sedation, the patient is able to make a purposeful response to verbal or tactile stimulation whilst having the dental procedure.
This is usually accomplished by the use of a narcotic and/or a benzodiazepine. By comparison, patient responsiveness during “deep sedation” is intact but fear and anxiety stimulus is suppressed.
Depending on the procedure the total dose given may vary and range from minimal to moderate. For minimal sedation, oral sedation is recommended and it’s usually taken about an hour before the procedure. The medication will make the patient drowsy, although he/she will still be awake and need a local anesthetic. At times a larger dose may be needed and given to produce moderate sedation. This is the type of anesthesia most commonly associated with sedation dentistry. Some people become dazed enough from moderate oral sedation to actually fall asleep during the procedure. They usually can be awakened with a gentle shake. This type of sedation for dentistry is very safe and have near to none side effects. A responsible relative is essential to monitor while the patient gets sedated and also take him/her home and further monitor up to 24 hours. Instructions will be explained by the dentist before, during and after the procedure. Regardless of the type of sedation we use, patients also need a local anesthetic at the site where the dentist is working in the mouth. This most probably the patient will not remember after the sedation effect wears off.
Nitrous oxide (N2O) is simply a gas which you breathe in, it has no color, smell, and doesn’t irritate. It is administered through nose for handling anxiety during treating or providing dental care.
Also called as Inhalation sedation, laughing gas, relative analgesia, happy gas, nitrous, nitrous oxide, N2O-O2; this is more used than any other sedation technique type. Inhalation sedation achieved with nitrous oxide
(N2O) and oxygen (O2) together has been described as representing most ideal clinical sedative technique.
After 5 minutes or so of breathing in the gas along with oxygen, patient feel a euphoric effect spread throughout the body giving a happy feeling.
Some people find that there will be a hallucinating effect which is auditory or visual effects. Patients will feel a bit light headed and often people get the giggles that make nitrous oxide one of the drugs of choice for young people. When used with oxygen, nitrous can be administered for a prolonged period of time and people can come out of the effect almost instantly with no side effects what so ever.
