Anesthesia

Anesthesia or anaesthesia ("without feeling" from Greek) is a condition of controlled, temporary loss of sensation or consciousness caused for medical purposes. These can contain any or all of analgesia (relief or pain prevention), paralysis (relaxation of muscles), amnesia (loss of memory), and unconsciousness. A patient under the influence of anesthetic medicines is called anesthetic. The clinician selects one or more drugs in preparation for a medical procedure to achieve the types and degree of anesthesia characteristics that are appropriate for the type of procedure and the particular patient. The types of medications used include general anesthetics, local anesthetics, hypnotics, sedatives, medicines that inhibit neuromuscular, opioids, and pain relievers. The risks of complications during or after anesthesia are also difficult to distinguish from those of the operation for which anesthesia is administered, but they are primarily linked to three factors: the patient's safety, the difficulty (and stress) of the operation itself, and the technique of anesthetics. Of those factors, the patient's wellbeing has the greatest effect.
