What's the difference between anaesthetic and sedation?

Anaesthetic


Definition:

  • (a.) Capable of rendering insensible; as, anaesthetic agents.
  • (a.) Characterized by, or connected with, insensibility; as, an anaesthetic effect or operation.
  • (n.) That which produces insensibility to pain, as chloroform, ether, etc.

  • (9) An epidemiological survey carried out in 460 public and private institutions chosen at random country-wide in France made it possible to study injuries whose treatment had necessitated an anaesthetic.
  • (10) In order to investigate the ability of a computer-assisted continuous infusion (CACI) system to maintain constant plasma levels of sufentanil during cardiopulmonary bypass (CPB) using pharmacokinetic data derived from healthy surgical patients to determine the infusion rate, ten patients were anaesthetized with diazepam, enflurane and oxygen until ten minutes prior to the expected time of initiation of CPB.
  • (11) Molecular biology and electrophysiology have shown different mechanisms of action on this sodium channel, which depend on the chemical structure and electrostatic charge of the local anaesthetic molecule.
  • (12) Chloralose-urethane is considered a suitable anaesthetic in rats when studying the effects of noradrenaline and guanethidine.
  • (13) The increase probably reflects an inhibition of the re-uptake of released 3H-noradrenaline; in addition, phencyclidine appears to enhance the release of noradrenaline per pulse.--The actions of phencyclidine and ketamine on central noradrenergic neurones may contribute to the characteristic psychotropic side-effects of these general anaesthetics.

  • (20) Seven or 14 days of treatment with the beta 2-adrenoceptor agonist clenbuterol, 0.3 mg kg-1, s.c., twice daily, increased the basal mean blood pressure in normotensive urethane-anaesthetized rats.

Sedation


Definition:

  • (n.) The act of calming, or the state of being calm.

Example Sentences:

  • (1) The effects of sessions, individual characteristics, group behavior, sedative medications, and pharmacological anticipation, on simple visual and auditory reaction time were evaluated with a randomized block design.
  • (2) Open field behaviors and isolation-induced aggression were reduced by anxiolytics, at doses which may be within the sedative-hypnotic range.
  • (3) However, the degree of sedation caused by diphenhydramine was significantly greater than that caused by cimetidine (P = .0001).
  • (4) Although lorazepam and haloperidol produced an equivalent mean decrease in aggression, significantly more subjects who received lorazepam had a greater decrease in aggression ratings than haloperidol recipients; this effect was independent of sedation.
  • (5) Adverse outcomes were reported more frequently by consultant physicians, by those who 'titrated' the intravenous sedative, and by those who used an additional intravenous agent, but were reported equally frequently by endoscopists using midazolam and endoscopists using diazepam.
  • (6) Alterations in mean systolic blood pressure appeared to be modest, consisting of a 10 percent decrease from the control level, related to sedation, and a 10 percent rise from baseline during the procedure, associated with a concomitant mild tachycardia.
  • (7) We have evaluated the action of hypnotics on the sleep-wakefulness cycle in freely implanted rats during their maximally active period because it is easier to estimate the duration of the sedative effect.
  • (8) A survey into the current usage of tracheal tubes and associated procedures, such as various sedation regimes and antacid therapy, in intensive care units was carried out in Sweden by sending a questionnaire to physicians in charge of intensive care units in 70 acute hospitals which included seven main teaching hospitals.
  • (9) The results show that both drugs possess sedative, antispasmodic, antipyretic, antiinflammatory, cardiotonic and hypotensive effects, the strength of effect and toxicity being similar.
  • (10) This suggests that the fluphenazine-induced sedation is not mediated via its effect on brain NA content, but is possibly due to the effect of the drug on NA turnover rates in the brain.
  • (11) The introduction of non-sedating H1-selective antihistamine drugs and local corticosteroids has been an important therapeutic advance.
  • (12) Neither a sedative nor other side effects could be seen.
