Intravenous conscious sedation
This is the most commonly used technique for adult patients who are generally fit and well. It is usually delivered via a small plastic tube in the back of the hand or arm. A sedative medication called midazolam is given through the tube and the amount required is tailored to each patient. For patients who are anxious about needles we sometimes advise using inhalation conscious sedation to relax them and provide some pain relief prior to the injection. We can also use EMLA cream or freeze spray to numb the back of the hand in advance.
Most patients receiving intravenous conscious sedation are more deeply sedated compared with inhalation conscious sedation and many patients will not remember the procedure, although they are still awake. This technique is ideal for highly anxious patients who need prolonged or more invasive procedures including the treatment of multiple teeth.
This treatment is available to patients who are aged 18 years and over, where appropriate.
