Operation Theatre Essentials

An operation theatre is a sterile room where delicate surgical operations are carried out. Operation theatre is also known as operating room or operation suite. Operation rooms should be spacious, easy to clean and well maintained. Usually operation theaters have a single door for entry and exit and are window less. Automated systems for temperature and humidity control are installed inside.

Operation theatre rooms are equipped with oxygen, suction and other gases. Major equipment consist of a table called an operation table and an anesthesia cart. Surgical instruments are arranged in a surgical tray. Disposable items are placed in a container. There is a scrubbing area just adjacent to an operation tray where the nurses, doctors and surgeons are required to scrub themselves (before entry). Visitors are strictly not allowed in the operation theatre so waiting chairs for the patient’s visitors are also placed outside the operation theatre.
