CRITICAL LOCUS REQUIRMENTS

THE OT COMPLEX MANAGEMENT
THE OT PLAN AND DESIGN

Where should it be located?
All operating theatres should be centralized in one operating
Area rather than spread in the hospital.
this has been shown to be the most economic approach;
-For good engineering and
-Focused nurse’s services,
-Use of equipment and
-Training of staff.

How is it designed?

Present trends in hospital design favor the low-rise building,
Two/three floors high.
With an internal courtyard. This enables maximum use of natural light and ventilation.
The operating department should be constructed separate from general traffic and air movement in the rest of the hospital.

How to plan?
Movement of patients is made easier if at the time of planning
The requirement of the operating department surgical wards and
Intensive care unit (ICU)
Accidents and emergency departments (AED)
Radio diagnostic (X-ray) departments are all considered.
The laboratory facilities should also be close by.

How to Design and Control Environmental?
The term operating suite is sometimes used to designate the room used for surgery.
This room is usually 400sq ft with minimum of 20 feet distance from cabinets and wall shelfs.
Special surgery suits cardiac, orthopedic neurosurgery and minimal invasive surgery and requires 600 sq ft. of space.
The support areas (changing rooms, scrub and utility
Rooms) are separate.
All operating suites are similar in design.

They are roomy enough to allow scrubbed staff to move around
Sterile equipment without the risk of contamination.
The design is such that dust is not trapped in areas that would be difficult to clean.
The surface vinyl material is free of joints and crevices.

The operating suite, is designed to insure maximum patient safety

* The floors, ceilings, and other surfaces are smooth, non-
Porous, and made of fireproof materials.
* The smooth surfaces allow thorough cleaning and prevent the
trapping of biologic material that could cause cross
Contamination
* All surface materials are made to withstand frequent washings
And cleaning with strong disinfectants
The ventilation system in the surgical suite has filters to
Prevent the contamination of the clean environment by
Air-borne bacteria.
The entry of air is thru high up vents
* The current requirements is, 15 exchanges of air per
Hour, 3 of which must be fresh air.
• Clean air exchange is possible if there is a positive pressure within the suite.
• This air is derived directly from the outside to avoid circulating air that might be contaminated By passage through other areas of the hospital
* The humidity is also controlled to minimize static
Electricity and consequent ignition of any flammable
Solutions or objects used in the operating room.
* The ideal humidity level to achieve minimal static and also
Reduce bacterial growth is 30% to 55%.
The air temperature
Is maintained at 200C to 240C (680F to 750F).
* Emergency signal. The O.T.Management committee should
Consider installing an alarm system in case of a life
Threatening emergency. The activation of this alarm will
Save valuable time to mobiles. The emergency designate staff
And direct them to the site of the emergency.
