An anesthetic stops you feeling pain during a medical surgical procedure (an operation).
Modern anesthetics are complex, they make you unconscious, paralyze you and take away pain.
stops you from feeling pain
You possibly mean "anesthetics" since anestnetics is not an English word. Anesthetics are drugs used to render a person unconscious, such as during a surgical procedure, or it can be used for the drugs used to block the pain by some other means like with local nerve blocks, epidural blocks, or local Novocaine to numb a small area before some invasive procedure is done in medicine.
The term 'anaesthetic' covers a wide range of difference drugs and substances designed to do different things.
Anaesthetics may be classed as general or local.
A general anaesthetic involves making a patient completely unconcious (anaesthesia) AND unaware of pain (analgesia). This state can be achieved in a number of different ways, but often begins with a drug (such as propafol) being administered into the patient's veins called an INDUCTION AGENT. This has the benefit of acting very quickly, and if left at that, would generally last about 20 minutes in most adults.
As most surgeries go on longer than 20 minutes, a MAINTENANCE AGENT will often be given throughout the operation, usually as volatile gas that the patient inhales with oxygen through a mask. Examples of commonly used volatile anaesthetic gases are sevoflurane and isoflurane. These have the benefit of being fairly short acting, so the patient remains asleep for as long as the gases are switched on. At the end of the operation, the gases can be turned off, and the patient should begin to wake up quite soon after.
Muscle relaxants are given in some surgeries where the patient is needed to be completely still (some operations on bones and joints) or where natural muscle tone needs to be relinquished (such as in open abdominal surgery).
Analgesia (pain relief) is usually given into the veins at the beginning of the operation and throughout. There are many, many different types and classes of analgesic drugs, but morphine and its family of drugs are common. These sorts of drugs (called opiates) are great at taking pain away but often make people feel sick, so invariably a special drug called an anti-emetic (such as ondansetron) is also given to combat this.
General anaesthetics are very safe when done correctly and admistered by an experienced anaesthetist with appropriate patient monitoring.
Local anaesthetics covers a wide range of different techniques where the patient is awake. These include:
Topical anaesthetics - creams and gels rubbed onto the skin or gums to combat pain
Regional anaesthesia - injections of anaesthetic around specific nerves in the body
Specialised regional anaesthesia - special types of 'nerve blocks' such as epidurals or spinal anaesthetics, often used when women need pain relief when in childbirth, or for patients are particularly painful operations (e.g. removal of the colon)
This is a very brief overview of anaesthetics - you could (and many have) write thousands of long books on the subject!
Anaesthetics are chemicals that makes a patient go unconscious and/or feel no pain.
Antiseptics are chemicals that are used to make certain areas, tools and items in a hospital sterile, so no diseases can infect the patient in an operation
Topical anesthetics.relieve pain and itching by blocking the sensory nerve endings in the skin. They are.in a variety of nonprescription products that are applied to the skin.These products are sold as creams, ointments, sprays, lotions, and gels.
Anaesthesia literally means 'without sensation' (from ancient Greek words), and anaesthetics are the drugs that bring about anaesthesia.
A local anaesthetic removes sensation in one part of the body. The patient remains conscious.
A general anaesthetic removes sensation in all of the body. The patient is unconscious and has no memory afterwards of what happened during general anaesthesia.
Anesthesia is a method of preventing sensation, or the loss or prevention of pain as caused by anesthesia.
It depends on the anesthesia.
Unless advised by a doctor, topical anesthetics should not be used on or near any part of the body with large sores, broken or scraped skin, severe injury, or infection. They should also not be used on large areas of skin.
There are different types of anesthetic. Some states may allow assistants to apply topical anesthetics, but no state allows assistants to inject local anesthetics or induce nitrous oxide or general anesthetics.
One common use for topical anesthetics is to relieve pain from problems such as sores in the mouth, skin scrapes, and hemorrhoids. The other broad category of use for topical anesthetics is to prevent pain from medical examinations or procedures
You need to understand that piercings cant be frozen, injection and topical anesthetics will distort the tissue and cause the piercing to be twisted and misaligned besides this point professional body piercers can not legally use injection anesthetics and topical anesthetics only work for specific piercings. Really what's the point in getting anesthetic for a piercing if you need to be poked with a needle to get the piercing done in the first place.
Topical anesthetic medications must be selected carefully and used in proper amounts in order to prevent harmful reactions. For instance, some topical drugs should be used only on intact skin to avoid rapid absorption into the body.
The use of injection anesthetics by professional body piercers in North America is illegal. Talk to your piercer there are other options like topical anesthetics, but these should only be used with the knowledge and supervision of your piercer.
Overall, topical anesthesia tends to be very safe. Minor problems might include discoloration of the skin at the application site or an uncomfortable feeling of numbness that lasts longer than expected.
Yes it is, unless the dentist does anything illegal. But usually topical anesthetics are widely sold from dental supply compagnies, and the price isn't expensive, so there is no reason for dentists to buy anything cheaper and not controlled.
Anesthetics are used during anesthesia. There are many different anesthetics used, the most common being Propofol.
A local anesthetic is a mild anesthetic used to numb a specific area of the body (such as a Novocaine shot). Novocaine is the most commonly used local anesthetic, though there are topical local anesthetics that can be rubbed on the skin (i.e. Oragel)
Commonly used, twenty-first-century drugs include benzocaine, lidocaine, prilocaine, and tetracaine, These drugs come in several application forms, such as cream, jelly, ointment, solution, and spray, are available in varying strengths
Pain relief remedies, such as topical anesthetics, may be used to reduce the pain of the sores.
