What is Anaesthesia?

Relieving pain and suffering is central to the practice of anaesthesia, which involves administering medications to eliminate sensations, including pain. This allows doctors to perform medical and surgical procedures without causing undue distress or discomfort to the patient.

Most people undergo anaesthesia at some stage in their lives. They may be anaesthetised for a short, simple day surgery or for major surgery requiring complex, rapid decisions. Modern anaesthesia is relatively safe due to high standards of training that emphasise quality and safety. There also have been improvements in drugs and equipment. Advances in anaesthesia have also resulted in patients being able to have more complex surgery as a day stay procedure because of more rapid recovery with modern anaesthesia; and they have facilitated many of the advances in surgery.

Australia and New Zealand have one of the best patient safety records in the world, thanks to increased support for research to improve anaesthesia. Specialist anaesthetists become involved in the patient’s care prior to surgery with assessment of their medical condition and planning their care as part of the surgical team. They closely monitor the patient’s health and wellbeing throughout the procedure and help to ensure a smooth and comfortable recovery.

There are several types of anaesthesia. General anaesthesia produces a drug-induced state where the patient will not respond to any stimuli, including pain. It may be associated with changes in breathing and circulation. Local anaesthesia involves the injection of local anaesthetic near the surgical site and is usually used for minor surgery. It may be used alone or in combination with sedation or general anaesthesia. Regional anaesthesia includes “nerve blocks” and “spinal blocks”. This is when local anaesthetic is injected in the vicinity of major nerve bundles that supply body areas such as the thigh, ankle, forearm, hand or shoulder. Procedural sedation is used for procedures where general anaesthesia is not required. It allows patients to tolerate procedures that may otherwise be uncomfortable or painful.

The majority of procedures performed at OBAS centres (such as wisdom teeth extraction and dental implants) are performed using general anaesthesia. This ensures the patients will not experience any discomfort during the procedure, and will have no memory of anything unpleasant. While the patient is under general anaesthesia, local anaesthesia will also be used which ensures patients wake up pain free.

Can I have my dental work / procedure done under general anaesthetic?

Office based anaesthesia can be appropriate for many different types of dental or minor surgical procedures. Whether it is appropriate for you to have your procedure performed under office general anaesthesia will depend on the nature of the procedure, your age, and your general state of health.

You are advised to discuss with your treating dentist / doctor about your suitability for having your procedure done under office general anaesthesia.

Is my practice suitable to be set up as an OBAS centre?

Office based surgery is a rapidly growing industry. The potential benefits to you, the practitioner, are many:

• You are able to look after your patients in your own clinic, without the need to refer to external services.
• Scheduling becomes easy, there is no need to fit in around a busy theatre/day surgery centre - you can book patients into surgical sessions that suit you.
• Procedures can be done using your own equipment and staff.
• Patients value the personal service, ability to be cared for at their regular clinic, with greater privacy, and usually lower cost than hospitals/day centres.

Office based surgery may be suitable for ambulatory procedures that would otherwise have traditionally been performed in day centres or hospitals as day cases. Common examples include dental extractions or implants. However, office based surgery can safely extend to other surgical disciplines for minor procedures.

OBAS has extensive experience in the field of ambulatory surgery and anaesthesia. To determine if this is the optimal model for your practice, OBAS performs a full assessment of the clinic, as we have done with many centres. A written report is produced detailing the suitability of your facility providing office based anaesthesia. The report specifies the requirements to make your facility OBAS compliant. At this point, if the model is appropriate and you wish to proceed, OBAS provides all necessary support and equipment in the establishment, as well as all ongoing anaesthetic services.
