'Sedation' is a
medical procedure involving the administration of
sedative drugs, generally to facilitate a medical procedure with
local anaesthesia.
Uses
Sedation is typically used in procedures such as
endoscopy,
vasectomy, or minor surgery and in
dentistry for reconstructive surgery, some cosmetic surgeries, removal of impacted
wisdom teeth, or for high-anxiety patients. Sedation methods in
dentistry include inhalation sedation (using
nitrous oxide), oral sedation, and intravenous (IV) sedation. Inhalation sedation is also sometimes referred to as ''Relative Analgesia''.
Sedation is also used extensively in the
intensive care unit so that patients who are being
ventilated tolerate having an
endotracheal tube in their
trachea.
Risks
Airway obstruction,
apnea and
hypotension are not uncommon during sedation and require the presence of
health professionals who are suitably trained to detect and manage these problems.
Levels of sedation
''Sedation scales'' are used in
medical situations in conjunction with a medical history in assessing the applicable degree of sedation in patients in order to avoid under-sedation (the patient risks experiencing pain or distress) and over-sedation (the patient risks side effects such as suppression of breathing, which might lead to death). Typically, levels are (i) agitation, (ii) calm, (iii) responsive to voice only, (iv) responsive to shaking only, (v) responsive to pain only, and (vi) not responsive.
Examples of sedation scales include: MSAT (Minnesota Sedation Assessment Tool) and the Ramsay Scale (Ramsay, et al. 1974)
