No one enjoys going to a dentist to have a tooth pulled, even though the tooth may be extremely painful. The experience, although still not completely painless, is nevertheless a far cry from what it was prior to 1846. Back then, there was no...

The discovery and development of anesthesia is one of the most important medical discoveries of the nineteenth century. It not only relieved pain, it also allowed doctors to perform life-saving surgical procedures, thereby increasing a person's...

Anesthesia The loss of feeling or sensation. It may be accomplished without the loss of consciousness, or with partial or total loss of consciousness. Anesthesiology is a branch of medical science that relates to anesthesia and anesthetics. The...

Anesthesia is the loss of sensation of painful stimuli either with or without loss of consciousness. Anesthetic agents produce a state of anesthesia. Anesthetics can be broken down into two basic categories: general anesthetics (those that cause loss...

The term "anesthesia" refers to insensibility to pain. Efforts to ease or eliminate pain are as old as pain itself. The early Chinese used both acupuncture and Indian hemp to dull the perception of pain. Ancient Hindu civilizations used henbane and...

Loss of sensation resulting from pharmacological depression of nerve function caused by administration of a DRUG or by other medical interventions, or from neurological dysfunction usually by damage to a nerve or receptor. Somewhat arbitrary divisions...

Aesthesia is the depression or numbing of nerve pathways in all or part of the nervous system. The effect of anesthesia is the loss of sensation, principally the loss of pain. Thus, anesthesia functions to keep a patent free from pain during surgery. A...

Drugs that reversibly depress neuronal function with accompanying loss of pain perception (ANALGESIA) and/or other sensations (anti-nociceptive; see NOCICEPTION). Drugs that induce a state of ANAESTHESIA fall into three main categories. (1) General: an...

A drug that induces a lack of sensation when applied locally to a relatively small region. Typically, local anaesthetics block nerve conduction in the affected region, thus reducing or blocking transmission of PAIN signals to the brain. Local...

Medical specialty dealing with anesthesia and related matters, including resuscitation and pain. Originally concerned only with general anesthesia in the operating room, anesthesiology now includes epidural anesthesia (injection of local anesthetics...

A substance that induces loss of sensation in living tissue. General anaesthetics are substances used in medical procedures to produce a reversible state of unconsciousness in a patient, usually during surgery. Local anaesthetics induce a localised...

Agent that produces a local or general loss of sensation, including pain, and therefore is useful in surgery and dentistry. General anesthesia induces loss of consciousness, most often using hydrocarbons (e.g., cyclopropane, ethylene); halogenated...

Anesthesia or anaesthesia (see spelling differences; from Greek αν- an- “without” + αἲσθησις aisthesis “sensation”) has traditionally meant the condition of having the feeling of pain and other sensations blocked. This allows patients...
