A combination of intravenous anaesthetic, sedative and pain relieving medications is administered to create a very sleepy and pleasant dream-like state for the whole procedure so that you will be relaxed, comfortable and unaware of your surroundings while still maintaining the ability to breathe on your own, move and able to obey commands. The vast majority of people have no memory of the procedure. Memory before and after IV sedation is usually not affected. Patients often comment that the whole procedure has passed in only a few minutes when in reality it may have been several hours. Intravenous sedation also allows patients to avoid the risks, cost and time involved with having a general anaesthetic. It allows your dentist to care for you at their clinic and is safer, allows you to recover quickly and has minimal side effects compared to undergoing a general anaesthetic.
Intravenous sedation is available and very effective for any dental procedure. It is suitable and extremely safe for most people. No procedure is too small for IV sedation. Intravenous sedation is beneficial for patients who:
You will be continuously monitored with all the Australian and New Zealand College of Anaesthetists (ANZCA) recommended standard hospital grade full monitoring along with intravenous fluids as well as 100% oxygen therapy available via nasal prongs during the entire intravenous sedation and dental procedure.
An advanced programmable syringe driver, routinely used in all hospital theatres in Australia, will administer an accurate and continuous infusion of intravenous anaesthetic, sedative and pain relieving medications via a small IV cannula/drip placed in your arm or hand. The intravenous medications work quickly and are very effective and you will drift off into a relaxed, sleepy and pleasant dream-like state and you will be comfortable and unaware of your surroundings and the vast majority usually have no recollection of the procedure.
Local anaesthetic and/or any nerve blocks(for intra-operative and post-operative pain relief) are only administered once intravenous sedation is working so that there is no awareness and no memory of the needles or dental procedure in the vast majority of patients.
The comprehensive continuous patient monitoring performed (which includes end tidal CO2 levels(EtCO2), respiratory rate and pattern, oxygen saturation (SaO2), blood pressure, pulse/heart rate and rhythm, electrocardiogram(ECG) as well as anaesthetic medication levels monitoring) allows the anesthetist to accurately adjust and titrate the intravenous medications to the appropriate level required throughout the dental procedure. Although intravenous sedation is extremely safe, there will still be emergency and resuscitation medications and equipment available in the clinic in accordance with the Australian and New Zealand College of Anaesthetists(ANZCA) recommended guidelines.
Side effects and complications are rare with IV sedation. A very small minority of patients have dream-like recollections of the experience and can recall features of the clinic or verbal conversations but these are not distressing. IV sedation is generally very well tolerated and side effects/complications are rare and are more infrequent than compared with general anaesthesia. Transient minor side-effects can include dizziness and nausea. Intravenous anti-nausea medications are also given prophylactically so the risk of nausea is extremely low.
The relative contraindications or conditions where intravenous sedation should be ideally performed in a hospital setting instead of in a dental clinic include the following:
