The operating room, commonly abbreviated to OR, is the location within a hospital where surgical procedures are performed by surgeons. The OR is a sterile environment designed to prevent infection during surgery, and it contains all the equipment the surgical team needs to perform procedures and respond to complications.

What You'll Learn
The OR is a sterile environment to prevent infection
The operating room (OR) is the location within a hospital where surgical procedures are carried out. The OR is a sterile environment, designed to prevent infection during surgery.
Creating a sterile field reduces the number of microbes present. The operating room is a sterile field, and the furniture is arranged to minimise the risk of contamination. For example, furniture should be placed 12 to 18 inches from the walls or any objects that could contaminate the field. The back table, which is used to open all other supplies, is the main sterile field. An imaginary 1-inch border is considered unsterile and should be avoided when placing items on the field.
To ensure the OR is kept sterile, hospitals use a variety of sterilisation techniques. Steam sterilisation, which combines heat, moisture, and pressure, is one of the most widely used methods due to its efficiency and low cost. Other methods include vaporised hydrogen peroxide technology and ethylene oxide sterilisation, which are low-temperature methods used for instruments that cannot withstand high temperatures and pressures.
The OR is also brightly lit and air-conditioned to further prevent infection and ensure the surgeon can see clearly. The room contains all the equipment the surgical team needs to perform the procedure and respond to any complications.

Surgeons wear protective eyewear, gowns, gloves, and shoe covers
An operating room (OR) is a sterile environment in a hospital where surgical procedures are performed. It is brightly lit and air-conditioned to prevent infection and accommodate the needs of the surgical team.
Surgical gowns create a barrier against microorganisms, chemicals, and bodily fluids, thus maintaining aseptic conditions in the OR. Gowns, along with gloves, also prevent the transfer of bacteria between the surgical staff and the patient. Gloves are essential when touching any bodily fluids or when the surgeon has wounds on their hands. They protect both the patient and the surgeon from harmful microorganisms and infections.
Shoe covers are worn to maintain a sanitary environment by preventing dirt and microbes from entering the OR. They also protect the wearer from accidental spills and bodily fluids.

Patients are asked to arrive early and change into a gown
The operating room (OR) is the location within a hospital where surgical procedures are carried out. It is a sterile environment, designed to prevent infection during surgery. The OR is also well-lit and air-conditioned to ensure the surgeon can see clearly and to further reduce the risk of infection.
Patients are asked to arrive early for their surgery so that they can be prepared for their procedure. This includes checking in at reception and providing personal information, such as name, address, and phone number. Patients will also be asked questions about their health and may undergo a physical exam. It is important that patients are open and honest during this process to ensure the procedure can be carried out safely.
Patients are typically asked to change into a hospital gown before surgery. This is to ensure the surgical site is easily accessible and to reduce the risk of infection. However, the hospital gown is often associated with negative feelings of vulnerability and loss of control. Patients may feel that the gown affects their mood and perspective, and it can be a reminder of sickness and loss of health.
To improve patient well-being, some hospitals are introducing new designs for hospital gowns. These gowns aim to enhance patient comfort and dignity, providing a sense of independence and autonomy. Made from comfortable, natural materials, these gowns are also easy to put on and take off, even for patients with limited mobility. By addressing the negative connotations of the traditional hospital gown, hospitals can help to maintain a positive mental framework for patients during their care.

ORs are brightly lit and air-conditioned to prevent infection
An operating room (OR) is a sterile environment in a hospital where surgical procedures are performed. ORs are designed to prevent infections during surgery. They are equipped with all the tools and equipment that surgeons need to perform procedures and respond to complications.
Air quality in ORs is critical to preventing infection. Airborne contaminants can cause infections, and studies have shown that better air management may be preferable to simply increasing the volume of air. Air-change rates, which measure the volume of air exchanged per hour, are important for maintaining air quality. The current code for air-change rates in ORs is 20 ACH, but some facilities use a rate of 25 ACH.
Airflow in ORs is also important for preventing infection. Air velocity is measured to ensure that sterile instruments are being adequately protected from contaminants.

Digital ORs use data integration and advanced imaging
An operating room (OR) is a location within a hospital where surgical procedures are performed. It is a sterile environment that aims to prevent infections during surgery. ORs are also well-lit and air-conditioned to prevent infections and ensure the comfort of surgeons and patients.
Digital ORs are one of the three types of operating rooms, the other two being hybrid and integrated. Digital ORs are built around central data systems that integrate imaging, software, and video data systems. They enable the sharing, transfer, and collection of medical data, which may be used during or after an operation to assess outcomes and inform care plans.
Advanced imaging tools also include hybrid ORs with built-in imaging devices like CT scans, MRIs, and fixed C-arms. These imaging devices provide valuable information about the patient's internal structures, enabling surgeons to make more informed decisions during surgery.
Data integration in digital ORs allows for the sharing and transfer of medical data, including imaging data, patient records, and metadata. This integration enables real-time access to patient records, which can inform surgical procedures and improve patient outcomes. For example, India's Ayushman Bharat Digital Mission is building a nationwide digital health infrastructure that enables real-time access to patient records.
As ORs become more digital and connected, cybersecurity and data privacy have become critical concerns. Integration systems handle sensitive patient data, medical images, and device controls, making them attractive targets for cyberattacks. Hospitals are now implementing stronger security frameworks, including data encryption, secure access, and regular audits, to protect patient data and the integrity of connected devices.
