How anesthesia is given, and by whom
MedlinePlus says the medicine used for anesthesia may be given by injection, inhalation, topical lotion, spray, eye drops, or a skin patch. In some cases a dentist, nurse, or doctor may give an anesthetic; in other cases a person may need an anesthesiologist. MedlinePlus lists the uses of anesthesia as minor procedures, such as filling a tooth; childbirth or procedures such as colonoscopies; and minor and major surgeries.
Sedation words heard alongside anesthesia
MedlinePlus names three levels of sedation. With minimal sedation a person is awake but more relaxed. With moderate sedation, also called conscious sedation, a person may feel sleepy and not remember much, but can still respond when spoken to or touched. With deep sedation a person is very drowsy and may respond only to repeated or stronger stimulation. Monitored sedation is listed with the types of anesthesia: it makes a person relaxed or sleepy.
What it means
Anesthesia is the use of medicines, called anesthetics, to prevent pain during surgery and other medical procedures. It can cause a loss of feeling, awareness, or both. There are several different types. Local anesthesia numbs a small area, like a tooth or a cut that needs stitches, and the person is awake. Regional anesthesia numbs a larger area, like an arm, a leg, or everything below the waist. General anesthesia affects the whole body and feels like a deep sleep. Sedation may be used with anesthesia; unlike full anesthesia, it does not make a person completely unconscious. An anesthesiologist is a doctor who specializes in giving anesthesia. Overall health, medical history, the procedure and other factors help determine the type of anesthesia a person receives.
Anesthesia in Spanish
- Spanish term
- Anestesia
- Gender and article
- feminine: la anestesia
- Pronunciation
- ah-nehs-TEH-syah
Anestesia is a feminine noun in the Real Academia Española dictionary, which defines it first as pérdida temporal de las sensaciones de tacto y dolor producida por un medicamento. The same entry has a further sense, sustancia anestésica, so in Spanish the one word can name the loss of feeling and the substance that produces it. MedlinePlus en español calls the medicines anestésicos and the specialist doctor an anestesiólogo.
The types are named with the adjective after the noun: anestesia local, anestesia regional and anestesia general. The National Cancer Institute's Spanish dictionary describes them in the same terms as its English entry: loss of feeling in a small area of the body, in a part of the body such as an arm or a leg, and a complete loss of feeling and awareness that feels like a very deep sleep. For sedation MedlinePlus en español writes sedación, with the levels sedación mínima, sedación moderada o consciente and sedación profunda.
