SPECIALIZED STRUCTURES
HOSPITAL OPERATING THEATERS
Operating rooms, also called Surgical Suites or Surgical Theaters, are dedicated spaces where physicians and nursing staffs perform surgery and administer medications based on diagnoses. Hospitals have long functioned under best-practice procedures of maintaining aseptic conditions. The more sterile the environment is, the safer the patient during surgical procedures. The proper equipment and furnishings will help reduce recovery times from illness or injury, while contributing to the overall efficiency of the healthcare facility. Operating suites serve to protect both the patient and the medical staff; cleanliness is maintained to shelter patients from contamination and post-surgical infections, as well as prevent transmission of disease to hospital personnel. Operating Theaters are located in the main hospital or infirmaries, as well as emergency rooms/departments to more conveniently treat those in urgent need. Following surgery, patients are transferred to a post-operative location or isolation room for recovery. Positive outcomes in operating rooms largely depend on sanitation, safety and efficiency.
Operating theaters are spacious, easy to clean, well-lightened rooms with no windows or restricted windows. The air, temperature and humidity need to be regulated by special ventilation system.
MRI ROOMS – CT-ROOMS SUITES
Primarily utilizes non-ionizing electromagnetism and radio-frequency to image soft tissue for medical diagnosis. This typically requires special copper and/ or steel shielding, filters and internally screened window assemblies. This shielding is primarily to protect delicate electronics, computers and equipment from magnetic and/or radio-frequency damage and is performed by specialized companies involved exclusively in this spectrum and type of non-ionizing fields. Dual modality MRI/CT rooms do require radiation and magnetism shielding.
MRI suite is actually comprised of three rooms:
1. Scan Room
This room is where the magnet and the table live. It’s where your patients will be scanned.
2. Equipment Room
This space is home to the gradient cabinets, compressors, and other electronics that connect to the magnet.
3. Control Room
The technologist will work from this room during the scan. It houses a workstation (computer, monitor, etc.) along with a desk, chair, and any other office miscellaneous you might like to keep on hand.
Extra room/cabin for changing
While it’s not required, it’s very common for facilities to build in a small changing room for patients. This improves their experience and can also be a helpful place for you to store your QA phantoms, manuals, or other system accessories.
MRI Suite Dimensions
Recommendations for room dimensions vary by manufacturer, but here are some general minimums that should work for the majority of models:
- Scan Room: 21’-6” X 13’-4” with 8’-9” ceiling height (after shielding is installed)
- Equipment Room: 11’-0” X 11’-6” with 8’-0” ceiling height (after shielding)
- Control Room: 12’ X 8’ (this is typically ample room for workstation, desk/chair, and a bit of storage)
While minimum dimensions are OK to use in your site planning, be aware that they can result in increased service time. With only minimal space to work in, service personnel will need to exercise extra caution. Minimum dimensions can also restrict the possibility of HVAC or system-related upgrades that may need to be made in the future.
STERILIZED ASEPTIC ROOMS
Asepsis refers to the absence of infectious material or infection. Surgical asepsis is the absence of all microorganisms within any type of invasive procedure. Sterile technique is a set of specific practices and procedures performed to make equipment and areas free from all microorganisms and to maintain that sterility. In the literature, surgical asepsis and sterile technique are commonly used interchangeably, but they mean different things. Principles of sterile technique help control and prevent infection, prevent the transmission of all microorganisms in a given area, and include all techniques that are practiced to maintain sterility.
Sterile technique is most commonly practiced in operating rooms, labor and delivery rooms, and special procedures or diagnostic areas. It is also used when performing a sterile procedure at the bedside, such as inserting devices into sterile areas of the body or cavities (e.g., insertion of chest tube, central venous line, or indwelling urinary catheter). In health care, sterile technique is always used when the integrity of the skin is accessed, impaired, or broken (e.g., burns or surgical incisions). Sterile technique may include the use of sterile equipment, sterile gowns, and gloves.
Sterile technique is essential to help prevent surgical site infections (SSI), an unintended and oftentimes preventable complication arising from surgery. SSI is defined as an “infection that occurs after surgery in the area of surgery”. Preventing and reducing SSI are the most important reasons for using sterile technique during invasive procedures and surgeries.
RADIOLOGY / X-RAY ROOMS
In these rooms typical energy levels can range between 100kvp to 150kvp, with a downward table and chest wall bucky primary target beam area. Rooms are typically smaller in size from 10’0″ x 12’0″ and up to 16’0″ x 20’0″ and require shielded walls, x-ray glass control window minimum 18″ x 18″ or larger for a clear view of patient and procedures, and shielded door(s). Shielding is based on the specific imaging equipment utilized and typically will involve several different lead thicknesses depending upon primary beam and secondary scatter radiation fields, surrounding occupancy factors and other considerations.
Typically, states or countries have rules in effect that regulate the use of x-ray equipment. All rooms containing fixed x-ray equipment must be evaluated for shielding to keep x-ray dose to people in adjacent areas below regulatory limits.
The amount of shielding required is specified by a qualified radiation expert (QRE) and is designed to limit the radiation dose directly outside of a room or facility to 1 millisievert (mSv) per year or less. This is usually the regulatory dose limit for members of the general public.
In addition, a QRE evaluates the installed shielding by performing an area radiation survey of the x-ray room. This is to verify that the shielding was installed properly and that the installed shielding protects people outside the room as expected.
Nigerian government agency regulates the use of x rays where you live to determine if a particular facility is registered and inspected as an x-ray facility and is in compliance with federal regulations.
BIOLOGY LABORATORY FACILITY
The biology laboratory facility has a general ventilation system with air intakes and exhausts that are capable of providing source of air for breathing. The system also provides air for input into the local ventilation systems such as fume hoods. Labels and warning signs should alert employees to potentially hazardous materials and allow those unfamiliar with the laboratory surroundings to identify hazardous chemical use and storage areas, safety facilities, emergency equipment, exits, and aid emergency response personnel.
Types of Code Requirements That Affect Most Laboratory Construction Projects
- Ventilation—to maintain comfort and occupational health
- Fire prevention—to detect and suppress fires, in part by limiting quantities of flammable and hazardous chemicals
- Emergency power supply—to maintain operation of vital life-safety systems such as egress lighting, fire detection, and protection systems during electrical interruption
- Control of hazardous gases—to reduce the risk from and to control accidental releases of gases
- Building height—to limit the height of laboratory buildings based on chemical usage
- Safe mechanical system and water sewage system.
- All furniture must be sturdy. All work surfaces (e.g., bench tops and counters) must be impervious to the chemicals used. The counter top should incorporate a lip to help prevent run-off onto the floor.
