In general anesthesia (GA), drugs are administered by intravenous or inhalation routes which makes the person to be unconscious and do not feel or remember anything during the surgery. This patient is not wakened even by painful stimulation. General anaesthesia currently can only be performed in the operating room under the hospital setup where the sleep doctor (anaesthesiologist) will be the one to make the patient sleep.
GA is recommended for:
- Complicated, extensive, and prolonged treatment to be performed
- Working in difficult or multiple areas in the mouth
- Patient with special needs
- Uncooperative patient
- Patient with extremely dental anxiety – only if other form of sedation are ineffective
- The patient is unconscious – allows the dentist to perform surgery without concern of constantly moving, uncooperating or anxiety patient.
- Patient do not feel pain
- Patient cannot remember events occurred during the surgery
- Longer operating time
- The patient is unconscious – can be life threatening
- Higher risk of complications – higher risk of airway obstruction because patient unable to cough
- Patient cannot control the situation – do not respond to sound and touch
- Require assistant to maintain a patent airway – patient cannot breathe on his own
- Very expensive – require special equipment
- Patient must fast at least 8 hours before surgery
- Requires adequately and specially trained doctor (anesthesiologist) to perform
- Time consuming procedure – long recovery period
- Before administering GA, the patient should be assessed thoroughly by the anesthesiologist by taking detailed medical history, drug history, physical test, and extensive laboratory test. The patient should be explained about the procedure and informed consent form should be signed by the patient. Patient must fast at least 8 hours before the procedure.
- Then, GA drug administered intravenously or by inhalation to induce general anaesthesia.
- After GA is induced, the doctor will secure your airway by placing a tube into your lung via the nose, mouth or a opening in the neck to ensure sufficient oxygen to reach your lung before dental treatment begins.
- When dentist has finished the dental treatment, the doctor will stop the administration of GA drugs and begins to bring the patient back to consciousness. The patient should be monitored for 1-2days before discharging.
The uses for general anesthesia in dentistry have decreased over the years as other less invasive sedation techniques have evolved. Nevertheless, there are still many situations that require the use of GA.
- Dental Anxiety
- Gas Sedation
- Nitrous oxide delivery system
- Oral Sedation
- IV Sedation
- General Anesthesia
