Have you ever wondered just exactly it is that "laughing gas" is? Here it is explained in detail for your education.
Nitrous Oxide Gas or N20, often referred to as laughing gas or sweet air, is an effective anesthetic drug that has many benefits for patients seeking dental treatment.
Nitrous Oxide was first discovered by an English cleric named Joseph Priestley in 1774. Later, in 1800, Humphry Davy, an English chemist and physicist, picked up on his work. He subjected himself and animals to the gas and made many observations, most notably, that the gas produced a very pleasant sensation, and reduced the sensitivity to pain.
It was not until 1844, that a young Connecticut dentist named Dr. Horace Wells saw a public demonstration of nitrous oxide at a carnival and realized the possibility of using it for dental treatment. The next day, Dr. Wells had nitrous oxide delivered to his office, and had a colleague extract his own infected tooth under the influence of the gas.
The results were astonishing, and Dr. Wells continued to use N20 gas for patient treatment thereafter. Nitrous oxide is used in roughly one third of dental practices in the United States.
The benefits of nitrous oxide are many, and the risks are few. The gas is administered with a comfortable mask placed over the nose, and the patient is instructed to breathe in through the nose and out through their mouth.
As a precaution, patients should not eat anything for about two hours prior to use of the gas. The patient begins to feel a pleasant level of sedation in anywhere from 30 seconds to three or four minutes.
The cheeks and gums will also begin to feel numb in about a third of the patients. After the gas is adjusted to the appropriate dose, and the patient is relaxed and sedated, the dentist can comfortably give the injection (if needed) to the patient, and then proceed with dental treatment.
Dentists find nitrous oxide especially useful for fearful patients as well as young children. The effect of nitrous oxide is often remarkable. A patient that was anxious just a minute or two before treatment will become relaxed and calm.
Because N20 is so effective, dentists rarely need to prescribe Valium for anxious patients before treatment. If you are nervous before or during dental treatment, ask you dentist if he or she has nitrous oxide available -- it works wonders!
After the treatment is completed, the patient is given pure oxygen to breathe for about five minutes, and all the effects of sedation are usually reversed. Unlike IV sedation or general anesthesia, the patient can almost always leave the office by themselves, without an escort.
Nitrous oxide has few side effects. High doses can cause nausea in some patients, and about 10% of patients do not benefit from it.
If you find that you get severe nausea, or your extremities are going numb, ask the dental staff to remove you from the nitrous. You could simply be oversensitive to it, or even allergic.
Please call if you display the following symptoms following nitrous oxide sedation:
High fever and chills
Extreme irritability
Vomiting more than twice
Signs of an allergic reaction, such as wheezing, a rash or hives
Difficulty breathing - Call 911
When that happens, most people are content with the numbing shots alone, instead of combined with the gas.
Patients that are claustrophobic or have blocked nasal passages cannot use nitrous oxide effectively. Nitrous oxide is one of the safest anesthetics available.
Interestingly, it is also routinely used by anesthesiologists for general anesthesia in combination with other more potent gases.
