The document discusses the design of operation theaters. It explains that operation theaters are designed to facilitate functional and aseptic flow of patients and staff. They are planned according to architectural practices to create a healthy environment. Historically, operation rooms evolved from demonstration theaters of the 18th century. The layout considers patient flow and transportation of supplies. Operation theaters are divided into zones - the dirty outer zone, clean zone, and sterile core. The zones are separated by physical barriers to maintain different cleanliness levels. Recent changes due to COVID-19 include full personal protective equipment and sterilization of instruments.

6. CONT.
Operation theatre as the name suggests are the units in health care
organization which are concerned with manipulation of human bodies for
the purpose of treatment or diagnosis of health disorders. These should be
planned and designed according to the appropriate architectural practices
observed.
The basic principle in designing an OT is that the patients and staff should
flow functionally and aseptically from and to the OT so that effectiveness,
efficiency and safety in achieving the service functions are achieved. It must
create healthy and aesthetic atmosphere and environment for clients, public
and staff.

7. HISTORY

8. HISTORY
• In the past 300 years, the design of operation rooms and their
ancillary spaces has responded to changes in surgical needs and
practice.
• But in the 18th century the demonstration and teaching of surgery
became important, so dedicated rooms for surgical operations were
built. They were designed as theatres with accommodation for
spectators—based on the old anatomy theatres—such as the one
established at St Thomas’ Hospital, London, in 1751.

9. LAYOUT OF OT

10. LAYOUT OF OT
• Important design considerations include the mix of inpatient and
outpatient operations, patient flow, into and out of the operating
room (OR) area, the transportation of supplies and waste
materials to and from the OR, and flexibility to allow the
incorporation of new technologies.
• The operating theater should be zoned into aseptic and clean
areas in addition to being separated from the outer areas

11. ZONES
Zone Barrier Areas included
Dirty outer zone Physical Sluice, storage, waste disposal, outside
corridor, changing rooms
Clean Partial Supply store, disinfection room,
anesthetic room, recovery room.
Sterile core Physical Operating Room, sterile preparation.

12. MINIMUM SERVICES
INCLUDE
• Major operating room
• Recovery room

23. SCRUBBING AREA

24. RESTING AREA, LOUNGE AND
TOILET FACILITIES

25. STERILE AREA

26. STERILE AREA
This zone is also called as the restricted zone and it is actual
operating section of an OT and in this the rooms should be
located and arranged in such a way that the non-related
members are prevented from passing through the room so that
this area can be maintained in sterile condition.

27. • Wear full PPE , scrub suits during any surgical procedure.
• Check for the COVID report and if emergency, then all sterile
antiseptic procedure to be maintained properly for the need of
COVID to not spread to any other.
• Sterilization or even discarding the instruments post surgery is
safe practice.
• Post surgery, OT is also sterilized through fumigation method.

• Did your first build work, or did
you have to change your ideas?
Why?
• Did you have to change the
materials you used as you tested
your invention? Why?

31. The number of operating rooms and recovery beds and the sizes
of the service areas shall be based on the expected surgical load.
In the programe, the size, location, and configuration of the
surgical suit and support service departments shall reflect the
projected volume of outpatient. This may be achieved by
designing either an outpatient surgery facility, or a combined
inpatient-outpatient surgical suit. Therefore, clearly an OT design
is very important aspect in any surgical procedure.

32. ASSIGNMENT
What are the zones of OT? Explain.
