Related to operating theaters: Operating Suite
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.

operating theatreA room, or suite of rooms, designed for the safe performance of surgical operations. Much consideration is given in the design to minimizing the risk of infection. Walls and floors are commonly covered with washable material and are washed daily. Materials liable to build up charges of static electricity are avoided. Ventilation is arranged so as to avoid air contamination and exhaled anaesthetic gases are vented. Intense but shadowless illumination is provided by special lamps. X-ray and scan viewing boxes are often built into the walls. Ancillary rooms include changing rooms, scrub rooms, sterilizing rooms, anaesthetic rooms and recovery rooms.
