Conscious Sedation

Conscious sedation is a safe way to help you forget about a procedure that makes you worry you will panic or experience pain. It can only be offered for minor procedures and dental procedures.

It is safe because your vital signs are closely monitored by an expert doctor, and you are able to breathe and move throughout the procedure.

Sedation makes you sleepy and most people fall asleep, even though this is not the aim, but the effect of the sedatives and pain killers.

With sedation you are unlikely to remember anything about your procedure.

On the other hand, in hospital you would be offered a General anaesthetic, which paralyses you completely and they connect you to a breathing machine through a tube in your throat. This is essential where major surgery is involved, but can be avoided in minor or dental surgery.

If you are interested, please get your practitioner to contact us.

Who can benefit from
Conscious Sedation?




Pre-Sedation Instructions

If you suffer from any medical conditions or take any acute or chronic medicine, please inform us before the procedure. Please bring a list of any medications you take with you on the day of your procedure


If you feel sick or unwell, please contact us so that we can decide if it is necessary to postpone your treatment.


Please wear comfortable clothes with loose fitting sleeves and flat shoes.

Please ensure you have nothing to eat or drink 4 hours prior to the procedure, not even water. This is very important.


If you take regular medication please take this on the day of the procedure unless advised not to by your dentist/surgeon or myself. Diabetics need to discuss with me what medication/insulin they take on the sedation day.


Please arrive in good time for your appointment with a responsible adult to accompany you home.

A Patient Journey

1
Step

We email the pre- and post-operative information, a consent form and an invoice to the patient. The invoice can also be sent to the practice. We will call the patient to conduct a sedation consultation before their appointment.

2
Step

The patient attends the surgery, having starved for four hours. A responsible adult escort to take the patient home is a legal requirement, and is required to stay with them for the following 12 hours.

3
Step

The sedation equipment will be set up in the surgery. The patient is greeted and any questions regarding the sedation will be answered.

4
Step

The patient is cannulated and given some intravenous drugs to make them relax. The patient is closely monitored throughout the whole procedure.

5
Step

Optional IV drugs can be administered via a drip as necessary: IV Paracetamol, IV Voltarol, IV fluids and or/IV Dexamethasone

6
Step

Post-operative instructions will be explained to the escort while the patient recovers after the procedure.

7
Step

Once the doctor is satisfied that the patient is safe, they will leave them in the care of their escort. The patient will have amnesia from the procedure.

8
Step

The patient will be emailed the day after the treatment for feedback.

For Parents

If your child is offered sedation

We offer IV sedation in suitable children. IV sedation is successful for the majority of anxious children, but dentists usually offer gas and air as a first option.

The other option is being treated in hospital under GA (general anaesthesia), but there is usually a long waiting list for hospitals and some parents feel this is too invasive for their child, who only needs a minor dental or surgical procedure.

You may request IV sedation, but the decision will be joint between the treating dentist/surgeon and the sedation doctor, as we need to consider the National Guidelines.

When it is agreed that your child would need sedation, we will phone you at a suitable time to discuss the procedure.

Our nurse will meet you and your child an hour before the procedure to apply the numbing cream if needed and to get to know your child.

The sedatives and pain relief medication is then administered through the butterfly. Sedation is not dangerous as your child can still breathe, cough, move and react.

Your child will be closely monitored during the procedure and therefore parents cannot stay during the procedure. After the procedure you will be called in and your child will be in a recovery area and ready to go once they are strong enough to walk.

Recovery is usually within an hour after the procedure, which is much quicker than after a GA in hospital.

It will not be safe for your child to go home in public transport as they will be unsteady on their feet and others might be emotional.

We advise going home by car/taxi and staying home for the rest of the day until your child is fully recovered from the IV medication.

IV sedation involves placing a small “butterfly” (cannula) which most children find painless with distraction techniques and numbing cream.

Post-Sedation Instructions

A responsible adult must take you home after the sedation, and stay with you for the next 12 hours.

On arriving home, we advise the patient to have a small drink of water or squash. If they can tolerate this, then they may progress onto something bland to eat e.g scrambled egg.

The patient should not experience any nausea or vomiting after sedation. If they do vomit more than once, we advise them to contact myself or their surgeon/dentist.

The sedation will result in some amnesia. This is temporary and sometimes lasts for a few hours.

We advise the patient not to drive, operate machinery or have any alcohol for 24 hours following the procedure. We also advise them not to use anything electrical, e.g kettle, iron, drill…

We advise the patient not to make any irreversible decisions or sign any legal documents for 24 hours following the sedation.

If the patient is taking regular medication, we advise them to ask myself or their dentist/surgeon when they should take their next dose after the sedation.

We do not anticipate that you will have any adverse effects or complications. Should you become concerned about anything, please contact us directly.

Frequently Asked Questions

Patients who would like to be sedated are welcome to ask their doctor or dentist to contact us for more details.
Dentists, Doctors or Oral surgeons who wish to perform minor procedures under sedation are welcome to contact us for more details.

Any minor procedure can be done under conscious sedation:

  • Dental: extractions, root canal treatment, implants, fillings, periodontal treatment and crown preparations
  • Non-dental: any minor or non-invasive procedure
The length of sedation is tailored to suit the length of appointment. This can be anything from one to eight hours.

Patients who are healthy and have well controlled medical conditions e.g. diabetes, hypertension and asthma, are suitable for sedation (ASA I and II). Patients with significant or uncontrolled conditions e.g. severe heart disease, morbid obesity, need to be assessed on a case-by-case basis. Please contact us if you are unsure or have unusual cases and we will advise appropriately.

The aim of sedation is not to put you to sleep, but to make you drowsy/sleepy. Most people naturally fall asleep during the procedure. With conscious sedation you are able to communicate throughout the procedure but afterwards you will not recall anything.
Although it is rarely possible to remember following a conscious sedation, advanced sedation involves administration of analgesia and amnesics, which prevents patients having any unpleasant memories.
Conscious sedation is completely safe. Our doctors have done many sedations and know how to treat any emergency. If they are not sure they can always ask a more experienced sedation practitioner.
No, this is very rare. It is very unlikely that you will feel sick after the sedation, but by starving for four hours prior to the sedation it will make this even less likely.
Charges are based on the dentist/doctor’s estimated procedure duration and may vary depending on duration and distance. We are happy to send the practice an instant quote upon request. When calculating the appointment time an additional 30 minutes needs to be added to the treatment time for recovery time. Recovery could be even longer with procedures longer than four hours.
Payment can be made to Advanced Sedation directly or, if your dentist/surgery prefers you can pay them and we can invoice the surgery.
Our doctors have plenty of experience and a network of supporting colleagues if they need further advice.
Our doctors are registered with the General Medical Council (GMC), Society for the Advancement of Anaesthesia in Dentistry (SAAD) and members of the Association of Dental Anaesthetics (ADA). They all attend regular Continued Professional Development (CPD) as this is part of the GMC requirements for Revalidation. Some have a background in Emergency Medicine and others in Anaesthetics. Either way they have experience in sedation since working in various hospitals.
After the procedure, it is essential to have an adult present to take you home and stay with you for 12 hours. During the first few hours, please do not sign any legal documentation or operate any heavy machinery.

For safety reasons everyone is required to have an escort.

Advanced Sedation Ltd have always required an escort, this is reflected on our instructions to patients as well as requiring an escort signature before discharge. We sincerely apologise about the incorrect information that was previously shown on our website.
