Information for patients about Inhalational Sedation
(Happy air)

What is Inhalational sedation?

This type of sedation is suitable for all age groups from small children to older adults. It can enable patients who are anxious about coming to the dentist to have treatment in a relaxed and comfortable way. It is particularly suitable for short appointments and you are able to continue your day as normal afterwards.

How will it make me feel?

The effect of this sedation does vary between individuals. Most people experience a feeling like they are floating on air and have a warm sensation in their fingers and toes. They feel relaxed and happy hence its alternative name “Happy Air”. Some people describe it as a feeling similar to several alcoholic drinks without the side effects.

What is the gas and how is it given to me?

The gas given to you is actually a mixture of two gases, oxygen and nitrous oxide. This is the same as the gas mixture given to ladies during childbirth. It is administered to you using a small mask that fits comfortably over your nose leaving your mouth free. This mask can be unscented, orange or strawberry depending on your preference. A special machine controls the amount of nitrous oxide gas that is given to you. How much you need depends on how you feel. The dentist will adjust this to the correct level for you.

Will I be “knocked out” ?

This is not a general anaesthetic, even though it is a gas. You will not go to sleep during this treatment, but you will feel relaxed and comfortable. Things that made you anxious about dental treatment before will not seem such a problem to you. We will still need to make your gum numb for treatment using special cream and anaesthetic so you don’t feel a thing.
Is it safe?

As this mixture of gases includes oxygen, it is extremely safe. The dentist and nurse treating you have received special training in this type of sedation. The machine has a special safety mechanism so there is no possibility of the nitrous oxide being given without oxygen. The machine is checked before each appointment to ensure it is working correctly.

What must I do to have sedation?

The dentist must check your general health and it is important that you tell them about any medicines that you are taking from your doctor or pharmacist. They will ask you to complete a medical questionnaire. They will take your blood pressure and record your heart rate.

The dentist will explain the details of the treatment that you are having. If you wish to proceed, you must sign a consent form.

What to do on the day of treatment

· This type of sedation does not require you to have another adult with you. If it is your first time for this type of sedation or you are having a long appointment, you may prefer to have someone with you.
· Do arrive early for your appointment to allow any paperwork to be completed and visit the bathroom.
· Do continue to take any medicines that you usually take, unless told otherwise by the dentist
· Do tell the dentist if you have been to the doctor or hospital since the appointment was made.
· Wear loose fitting comfortable clothing. It is particularly important to have loose sleeves.
· Remove all nail varnish and heavy make up.
· Do not starve yourself before your appointment. Eat a light meal or snack and have drinks as normal.

Special precautions after inhalational sedation

· Remember that your mouth may still be numb, be careful not to bite or burn yourself until sensation returns to normal.
· Eat light and digestible food for the rest of the day.
· Continue to take any regular medicines as normal.
· The effect of the sedation will have worn off by the time you leave the surgery. You are safe to drive your car and return to work as normal immediately after your appointment.
