Related to Surgery theatre: operating room
A room in hospital which contains an operating table or similar device, generally accommodating one patient at a time, during which, under the direct supervision of a medical or dental practitioner, the patient undergoes an operative procedure for the prevention, cure, relief or diagnosis of disease, or in pregnancy, childbirth. An operating theatre must: allow positioning of the patient on the table or device so as to render the operation possible or convenient; have adjustable lighting powerful enough to permit fine or delicate work under aseptic conditions; provide sterile instruments and facilities for staff to change clothing; provide deeper pain relief than the basic sedation administered in the ward or local anaesthetic.
