The main difficulty with removing lower molar teeth (including wisdom teeth) is the difficulty in ensuring profound anaesthesia. The lower jawbone is dense and nerve blocks may be successful only about 50-60% of the time (if insufficient waiting time and only a single block is utilized). Patients with heavy musculature and a history of bruxism are more likely to encounter anaesthetic failure because of underlying chronic inflammation in the tissues surrounding their teeth. This is the main reason why patients and dentists have difficulties with extractions or procedures on lower molars.

Generally, wisdom tooth removal involving surgical extraction can be carried out with only local anaesthesia. With local anaesthesia, you will not feel any discomfort or pain during surgery since the tooth and surrounding area will be totally numbed. General anaesthesic for wisdom tooth removal is hardly used. But it is occasionally used when the surgery is carried out at the hospital, which also requires other surgeries at the same time. If you are particularly worried about the surgery, sedation would be a good option to relax during the procedure.

Thank you for your question and please also see the article I wrote on frozen shoulders here. Wrt the surgical treatment, MUA is basically where you are anaesthetised and the surgeon manually moves your arm to break the adhesions. There is a the risk of other trauma to the shoulder but it is an option. The arthroscopic approach requires more finess and surgical training/experience. This is where the surgeon uses a minimally invasive approach to then cut away at the adhesions from within.

The short answer is yes. Any medication, given as a single dose, will recede in effect. However, anesthesia practice has a strong safety emphasis and safeguards to prevent this situation from happening. This is where maintenance of anesthesia occurs. Machines monitored by the anesthesiologist throughout surgery will provide the anesthetic medication while other measurements such as the blood pressure and heart rate, give indications of such events. Well established and researched levels of anesthetic are maintained during surgery as well to reduce such occurrences.

Hi, IV sedation is always optional. Dental procedures may cause discomfort and cause a degree of anxiety. Hence dental procedurists always administer various forms of medication for relief of anxiety. This may range from oral tablets to having medication injected intravenously. On occasion, deeper sedation may be required; this is where an anesthesiologist will be booked for the procedure. This doctor stays throughout the duration of the procedure, monitoring your oxygenation, heart rate, and blood pressure while adjusting the level of sedation medication. I hope this helps!

Contrary to rumours you hear, gastroscopy is not really painful. In fact, most patients do not recall the procedure at all thanks to the sedation given to them. The sedation is usually given through a small plastic cannula inserted into the back of your hand just before the procedure. there is also a spay treatment given to numb your throat before the procedure. Gastroscopy takes approx 15 minutes to complete and your doctor will be able to explain to you the findings at the end of the procedure. At times, tissue samples may be taken for inspection under the microscope.

In Singapore, the surgical procedure of liposuction is regulated by the Ministry of Health. Only certified doctors are able to perform liposuction. There are many regulations in place such as Amount of fat removed Choice of facility where the procedure is carried out. These determine the type of anaesthesia that is used.

Anesthesia involves the use of 3 classes of medication-1. Anesthesia2. Analgesia 3. Muscle relaxants (depending on type of surgery and assessment by anesthesiologist)Use of such medication by untrained people is potentially disastrous hence this reply will be brief. Do discuss any further queries with your friendly anesthesiologist prior to surgery. Anesthetic drugs are used to induce and maintain the state of 'deep sleep', loss of reflexes and amnesia. Analgesic medication reduces the pain response. This is not just numbing the body to pain as most welness practitioners may suggest.
