Difference between anesthesia and analgesia
Anesthesia vs analgesia:
There exists a plethora of drugs in the world which are invented for various purposes particularly for relieving human beings from sickness, pain and suffering. They are thus categorized in to groups and anesthesia and analgesia two such groups of drugs which correspond to certain functions which they induce in the body.
What is anesthesia?
The term anesthesia refers to the lack of sensation which is exactly what is gained through this type of drug. Anesthetic drugs come in many forms such as medical gases, injection needles and medical breathing vapors. There are also four types of anesthesia- local- which only numbs one small area of the body, conscious or IV sedation which uses a mild sedative to relax the body and deliver pain medicine to relieve pain. During this procedure, the patient stays awake but may not remember the procedure afterwards, regional anesthesia which blocks pain in an area of the body, such an arm or leg or general anesthesia which affects the whole body during which the patient goes to a deep sleep.
What is analgesia?
The term analgesia refers to the reduction or relief from pain and they are known to affect the peripheral and central nervous systems of the human body, thus preventing an individual from feeling pain. Analgesic drugs are usually swallowed as a pill and they do not cause numbness in the body, except dulling the sensation of pain. While analgesics can be categorized in to two sections such as narcotics and non-narcotics, some examples for analgesic drugs can be listed as Tylenol, paracetamol, Morphine, Opium, etc.
What is the difference between analgesia and Anethesia?
While anesthesia refers to the lack of sensation which often involves the numbing or the cessation of sensation of a certain part of the body or the whole body in general, analgesia refers to the reduction or relief from pain which does not involve numbing the senses. While anesthetic drugs numb the senses by administering a drug for the patient to sometimes lose consciousness completely, analgesic drugs merely keep the individual from feeling pain which eventually result in the decrease of pain. Also, while analgesics may be targeted for the whole body, anethesics may be concentrated on to a specific part of the body.
Also, analgesic and anesthetic drugs take different forms. While most analgesic drugs come in pill form and need to be swallowed, anesthetic drugs often come in the form of gas, injection needles and medical breathing vapors.
While using analgesia, the patients are fully conscious and aware of what is happening. And yet, while using anesthesia, the patient might be partly or even fully unconscious and may not even remember what happened afterwards.
Anesthesia is often used during surgical instances and is controlled and administered by a person who specializes in anesthesia and yet, analgesia is taken in everyday life for common headaches and muscle pains and it is controlled by the individual itself.
