Operating Room Supply

Operating theater / Operating Room

An operating theater (also known as an operating room, operating suite, operation theatre or operation suite) is a facility within a hospital where surgical operations are carried out in a sterile environment.

Historically, the term “operating theatre” referred to a non-sterile, tiered theater or amphitheater in which students and other spectators could watch surgeons perform surgery. Contemporary operating rooms are devoid of a theater setting (though some in teaching hospitals may have small galleries), making the term “operating theater” a misnomer for the modern facility.

Operating rooms are spacious, easy to clean, and well-lit, typically with overhead surgical lights, and may have viewing screens and monitors. Operating rooms are generally windowless and feature controlled temperature and humidity. Special air handlers filter the air and maintain a slightly elevated pressure. Electricity support has backup systems in case of a black-out. Rooms are supplied with wall suction, oxygen, and possibly other anesthetic gases. Key equipment consists of the operating table and the anesthesia cart. In addition, there are tables to set up instruments. There is storage space for common surgical supplies. There are containers for disposables. Outside the operating room is a dedicated scrubbing area that is used by surgeons, anesthetists, ODPs (operating department practitioners), and nurses prior to surgery. An operating room will have a map to enable the terminal cleaner to realign the operating table and equipment to the desired layout during cleaning.

Several operating rooms are part of the operating suite that forms a distinct section within a health-care facility. Besides the operating rooms and their wash rooms, it contains rooms for personnel to change, wash, and rest, preparation and recovery rooms(s), storage and cleaning facilities, offices, dedicated corridors, and possibly other supportive units. In larger facilities, the operating suite is climate- and air-controlled, and separated from other departments so that only authorized personnel have access.

Operating room equipment

The operating table in the center of the room can be raised, lowered, and tilted in any direction.
The operating room lights are over the table to provide bright light, without shadows, during surgery.
The anesthesia machine is at the head of the operating table. This machine has tubes that connect to the patient to assist him or her in breathing during surgery, and built-in monitors that help control the mixture of gases in the breathing circuit.
The anesthesia cart is next to the anesthesia machine. It contains the medications, equipment, and other supplies that the anesthesiologist may need.
Sterile instruments to be used during surgery are arranged on a stainless steel table.
An electronic monitor (which records the heart rate and respiratory rate by adhesive patches that are placed on the patient’s chest).
The pulse oximeter machine attaches to the patient’s finger with an elastic band aid. It measures the amount of oxygen contained in the blood.
Automated blood pressure measuring machine that automatically inflates the blood pressure cuff on patient’s arm.
An electrocautery machine uses high frequency electrical signals to cauterize or seal off blood vessels and may also be used to cut through tissue with a minimal amount of bleeding.
If surgery requires, a Heart-lung machine, or other specialized equipment, may be brought into the room.
Heart lung machine takes the temporary control of the heart and lung during the surgery maintaining the circulation of blood and oxygen content of the body
Advances in technology now support Hybrid Operating Rooms, which integrate diagnostic imaging systems such as MRI and Cardiac Catheterization into the operating room to assist surgeons in specialized Neurological and Cardiac procedures.

Surgeon and assistants’ equipment

People in the operating room wear PPE (personal protective equipment) to help prevent germs from infecting the surgical incision. This PPE includes the following:

A protective cap covering their hair
Masks over their lower face, covering their mouths and noses with minimal gaps to prevent inhalation of plume or airborne microbes
Shades or glasses over their eyes, including specialized colored glasses for use with different lasers. a fiber-optic headlight may be attached for greater visibility
Vinyl gloves on their hands; latex is used as well, but much less common due to latex sensitivity which affects some health care workers and patients
Long gowns, with the bottom of the gown no closer than six inches to the ground.
Protective covers on their shoes
If x-rays are expected to be used, lead aprons/neck covers are used to prevent overexposure to radiation

The surgeon may also wear special glasses that help him/her to see more clearly. The circulating nurse and anesthesiologist will not wear a gown in the OR because they are not a part of the sterile team. They must keep a distance of 12-16 inches from any sterile object, person, or field.
