Inhalational anaesthetic substances are either volatile liquids or gases, usually delivered using an anaesthesia machine composing a mixture of oxygen, anaesthetics and ambient air, delivering it to the patient and monitoring patient and machine parameters. Liquid anaesthetics are vaporized in the machine. Many compounds have been used for inhalation anaesthesia, but only a few are still in widespread use. Desflurane, isoflurane, and sevoflurane are the volatile anaesthetics most widely used today. They are often combined with nitrous oxide. Older volatile anesthetics, such as halothane, enflurance and methoxyfluraneless are less popular. Researchers are also actively exploring the use of xenon as an anaesthetic. Injection anaesthetics are used for induction and maintenance of a state of unconsciousness. Anaesthetists prefer to use intravenous injections as they are faster, generally less painful and more reliable than intramuscular or subcutaneous injections. Among the most widely used drugs are: * Propofol * Etomidate * Barbiturates such as methohexital and thiopentone/ thiopental * Benzodiazepines such as midazolam and diazepam * Ketamine is used in the UK as "field anaesthesia", for instance at a road traffic incident, and is more frequently used in the operative setting in the US. The volatile anaesthetics are a class of general anaesthetic drugs composed of gasses and liquids which evaporate easily for administration by inhalation. All of these agents share the property of being quite hydrophobic (i.e., as liquids, they are not freely miscible with in water, and as gases they dissolve in oils better than in water).[information sourced and edited from Wikipedia "General Anaesthetic"]

What effect does laughing gas have on the patient?
It is a general anaesthetic. If too much is given, it will also create nausea and probably vomiting.

Who invented anaesthetics?
Salomon Nathans Dentz Jr is reputed to be the first person to use anaesthetic. The invention of anaesthetic, also called narcosis, is not that old. The first successful operation under anaesthetic was carried out in 1847. On that occasion chloroform was used. This method was slightly more effective than the ether that had previously also been used as an anaesthetic. Chloroform was used mainly by dentists to alleviate the patient's pain. For this purpose special anaesthetic masks were invented. The oldest known anaesthetic masks is that of the Amsterdam dentist Salomon Nathans Dentz Jr. Under the mouth and nose sections are sponges which hold the chloroform. This slowly anaesthetises the patient and keeps him under narcosis. Once the patient is unconscious the flap can be removed from the mouth and the operation can begin.

What is preanaesthetic check up?
pre anaesthetic check up is done on the patient undergoing certain surgical procedure. it should be done by a trained anaesthesiologist to detect any co-existing disease in the patient relevent to the anaesthesia being given and also to asses the fitness of the patient for the particular surgery. it helps the anaesthesiologist to be prepared for any mishaps beforehanded
What determines whether an anaesthetic is injected into the sub-arachnoid space versus the epidural space?
when an anaesthetic is injected into the sub-aracnoid sapce the patient can have a copmlete block that can lead to death,whilst into the epidural space painrelief will be effective.,
How is the ureteral stricture treated?
Initially under anaesthetic with urethral dilators.Then the patient is shown how to do these procedures themselves as stricture are recurring
Why do you have a loss of feeling in the mouth after anesthetic?
Because the anaesthetic is, by definition, meant to make the patient lose feeling, which of course includes pain.
Can too much anesthetic given to person with high blood pressure cause a stroke.?
I don't think so. It is much more likely that the stroke was going to happen anyway. There are many causes of strokes, and remember too that most people having surgery aren't very well, and are having surgery to try to make them better. If someone isn't well or has been seriously injured, problems such as strokes or heart attacks are more likely to happen. Under anaesthetic, the anaesthetist continually monitors the patient's blood pressure and if it is too high or too low, they administer medication to stabilise it. An anaesthetic is not just one drug. They first give you a drug to knock you out, and then they give you other drugs to keep you under anaesthetic. They correct any physical reactions that are not normal using drips or drugs. The patient is connected to monitors which the anaesthetist and the anaesthetic nurse concentrate on very attentively. At times the anaesthetist will decide that the patient isn't coping with surgery and they will tell the surgeon to stop the procedure and the patient then usually goes to Intensive Care until they are strong enough to be taken back to the operating theatre. If a patient had a stroke in theatre, the anaesthetist would notice straight away, and may advise that the patient should be taken to ICU. But the anaesthetic itself is very unlikely to cause the stroke.
Why emetics not given to unconscious patient?
Because - an emetic is given to force the patient vomit. If given to an unconscious patient - the patient could choke if the vomit enters the airway.
What does an anaesthetic doctor do?
An anaesthetic doctor is responsible for administering anaesthesia to patients before surgery or medical procedures. They monitor the patient's vital signs during the procedure and manage pain control post-operatively. They also play a crucial role in resuscitation efforts in emergency situations.
