Several methods of anesthesia are available. The method of anesthesia that is chosen for or by a patient depends upon the nature of the surgical procedure and the patient’s level of apprehension.
The following table illustrates the choices of anesthesia, a description of the anesthetic technique, and the usual indications for that technique.
Description
The patient remains totally conscious throughout the procedure. A local anesthetic (e.g. lidocaine) is administered in the area where the surgery is to be performed. Local anesthetic is used in conjunction with the other methods of anesthesia in all oral surgery procedures.
Usual Indications
Simple oral surgery procedures such as minor soft tissue procedures and simple tooth extractions.
Description
A mixture of nitrous oxide (laughing gas) and oxygen is administered through a nasal breathing apparatus. The patient remains conscious in a relaxed condition. Nitrous oxide has a mild sedative and analgesic (pain- controlling) effect.
Usual Indications
Simple oral surgery procedures to more involved procedures such as removal of wisdom teeth and placement of dental implants.
Description
Medications are administered through an intravenous line (I.V.). The patient falls asleep and is completely unaware of the procedure being performed. Medications most commonly used are Fentanyl (opiate), Versed (benzodiazepine), Ketamine, and Diprivan. Supplemental oxygen is delivered through a nasal breathing apparatus and the patient’s vital signs are closely monitored.
Usual Indications
Sedation is available for all types of oral surgery. A patient may choose this for simple procedures depending on their level of anxiety. Most people having their impacted wisdom teeth removed or having a dental implants placed will choose sedation. I.V. sedation may be necessary if local anesthesia fails to anesthetize the surgical site which often occurs in the presence of infection.
When it comes to anesthesia, our first priority is the patient’s comfort and safety. If you have any concerns regarding the type of anesthesia that will be administered during your oral surgery procedure, please discuss your questions with your doctor at the time of your consultation.
