Conscious Sedation

The information below is intended for patients preparing for a Conscious Sedation procedure at Lumus Imaging.

What is Conscious Sedation?

Sedation involves the use of the medicines used for anaesthesia which will make you feel relaxed and sleepy, but you will not be unconscious. These medicines may be  beneficial for you during your medical imaging examination or procedure if you find it uncomfortable  being confined in spaces or if have difficulty remaining still. This is sometimes referred to as conscious sedation. Most people recover from the effects of consious sedation in about 20 to 30 minutes.

How long will the procedure take?

Conscious sedation is given as part of  another procedure.

Please allow an extra hour to the time that the  procedure will take.  

Is there any special preparation required?

At the time you book your appointment, please advise our staff that your referring doctor has requested for you to have conscious sedation.

You will not be allowed to leave alone or drive yourself home and we require that a responsible adult take you home following the examination/procedure. Please ensure that this is arranged for the day of your appointment.

Whilst the side effects are minimal, you may feel drowsy for the rest of the day so we advise that you do not return to work and that you are not left alone for the remainder of the day. A medical certificate can be provided, you can ask our staff to arrange this on the day of your examination/procedure.

I still have questions; who can I ask?

Medical information can be complex, and you may receive information that you do not fully understand. It is important for you to consider the risks and outcomes of the procedure as well as your personal needs before making a decision to undergo the procedure.

If you have read this online information and are still unsure if this is the correct procedure for you; before making a booking, you should discuss your questions or concerns with your referring doctor in the first instance.
