Conscious Sedation

Conscious sedation is a technique in which sedative drugs (usually midazolam, a benzodiazepine) are administered intravenously to produce a deeply relaxed, drowsy state while you remain conscious and able to respond to simple instructions. It is combined with local anaesthetic so you feel no pain.

What it feels like

Most patients describe conscious sedation as feeling very calm, almost sleepy, with a pleasant disconnection from their surroundings. The majority have little or no memory of the procedure afterwards — this is a normal effect of the medication called anterograde amnesia.

What to expect

• A cannula (thin needle) is placed in a vein in your hand or arm
• Sedative is given slowly until you reach the desired level of relaxation
• Local anaesthetic is then administered — you should feel very little of this
• You must have someone to drive you home afterwards
• You should not drive, operate machinery, or make important decisions for 24 hours

Is it suitable for everyone?

Most healthy adults are suitable for conscious sedation. Certain medical conditions or medications may affect suitability — this is assessed at your consultation. It is particularly beneficial for patients with dental phobia, strong gag reflex, or who are undergoing longer or more complex procedures.
