What is intravenous sedation?
Intravenous (IV) sedation is used to help people who are very anxious cope with dental treatment. It is also useful if you are to have a surgical procedure performed.
How is intravenous sedation given?
“Intravenous” means that the drug is given through a vein. An extremely thin needle is placed into a vein close to the surface of the skin into either the back of the hand or the arm. The needle is then removed leaving a soft plastic tube in place called a cannula. The sedation drug is given through this plastic tube. Throughout the procedure, your pulse and oxygen levels are measured using a “pulse oximeter”. This clips onto a finger and measures pulse and oxygen saturation.
What does it feel like? Will I be asleep?
Intravenous sedation does not make you go to sleep. You will feel drowsy and relaxed and will be able to understand and respond to requests from your dentist. Time will appear to pass very quickly and most people remember very little of the treatment afterwards. You will still have local anaesthetic to numb the treatment area but this will not be given until you are sedated.
What drugs are used?
A sedative, anti-anxiety drug called midazolam.
