4. Types of Surgery
Elective-Performed on the basis of client’s
choice; not essential and may not necessary
for health.
Urgent- Necessary for client’ health, may
prevent additional problem from developing
(e.g. tissue destruction);not necessarily
emergency.
Emergent- Must be done immediately to save
life or preserve function of body part.
Required- Has to performed at some point; can
be pre-scheduled.
5. Types of Surgery
• Diagnostic-Allows to confirm diagnosis.
• Corrective- Excision or removal of
diseased body part.
• Reconstructive-Restore function or
appearance to traumatized or
malfunctioning tissues.
6. Types of Surgery
• Procurement for transplant- Removal of
organs and/or tissues from a person
pronounced brain death for
transplantation into another person.
• Constructive- Restores function lost or
reduced as result of congenital anomalies.
• Cosmetic- Performed to improve personal
appearance.
7. Types of Surgery
• Extent of surgery :
Simple- Only the most overtly affected areas
involved in the surgery.
Radical- Extensive surgery beyond the area
obviously involved; is directed at finding a root
cause.
• Location: Based on the area of the body on
which the surgery occurs (e.g. abdominal,
heart surgery).
8. Purpose of Surgery
• Diagnostic
– Determine or confirm a diagnosis
(breast biopsy, bronchoscopy)
• Cure/Curative
– Removal of diseased tissue, organ, or
extremity (appendectomy, amputation)

congenital anomalies (cleft lip repair)
• Prevention/Preventive
– (e.g. removal of mole)
9. Purpose of Surgery
• Reconstructive
– Rebuild tissue or organ that has
been damaged (skin graft after a
burn, total joint replacement
• Exploration – Surgical examination
to determine the nature or extent of
a disease (Laparotomy)
• Cosmetic Improvement –
(repairing a burn scar, or changing breast
shape)
10. Purpose of Surgery

21. Definition
• Specialized facility in hospital
where invasive treatment is
given under strict aseptic
controlled environment by
trained personnel
22. • An OT is that specialized facility of the
hospital where life saving or life
improving procedures are carried out
on human body by invasive methods
under strict aseptic conditions in a
controlled environment by specially
trained personnel to promote healing
and cure with maximum safety,
comfort and economy.
23. OPERATING ROOM
• The identification of physiological &
sociological needs of the client, & the
implementation of an individualized
program of care in order to restore
or maintain the health & welfare of
the patient before, during & after
surgical intervention.
24. PHILOSOPHY :
• To give service that aims to provide
comprehensive support physically,
morally, psychologically, spiritually, &
socially to a patient undergoing
surgery.
25. Support services play a large part in
maximizing efficiency by providing:
• Pre-operative preparation and assessment
•Available beds
•Sterile theatre equipment
•Portering, cleaning and maintenance staff.
26. Goals
Key elements to efficient use of operating
theatres are:
• Effective management
• Good communication
• Well trained staff
• Appropriate facilities and equipment
• Operational layout that allows flow of patients
27. Fundamental purposes of the O.R. :
It is a place. . .
1. To correlate theory & practice.
2. To develop skills in assisting the surgeon in
the operation.
3. To create a suitable sterile field for surgical
procedures to prevent complications.
28. OBJECTIVES OF PLANNING
• Promote high standards of asepsis
• Ensure maximum standard of safety
• Optimum utilization of OT and staff time
• Optimize working conditions
• Patient and staff comfort in terms of
thermal, acoustic and lighting
requirements
29. OBJECTIVES OF PLANNING………
• Allow flexibility
• Facilities coordinated services
• Minimize maintenance
• Ensures functional separation of spaces
• Provide a smoothing environment
• Regulate the flow of traffic
30. DESIGN PARAMETERS
• Avoidance of unrelated hospital traffic flow
• Convenient functional flow between
related departments like ICU,CCU etc
• Avoidance of outdoor noise
• Provision for future expansion
• Sliding doors
• Desirable floors to be smooth and non-
slippery
• Ceilings to be painted with washable paints
31. DESIGN PARAMETERS………..
• Taps in scrub room should be knee/elbow
operated /infrared operated.
• Provisions of high speed autoclaves
• Essential pharmaceutical storage
• X-ray films illuminators
• Emergency communicators that can be
activated without the use of hand
• Toilets
38. PHYSICAL EVIRONMENT
•Air – supply, direction of flow, pressure
changes in areas, air changes, monitoring
of quality
•Temperature and humidity – 21-24 centi,
45-60% humidity
•Lighting – at incision area 50 to 125K lux
with intensity cntrl, non-shadow ,blue-
white color of daylight, heat cntrl
39. Areas with higher hygienic
requirements for air quality.
• Areas with high clean-air requirements include the
operating theatre, any sterile preparation and pre-
operative areas, sterile storage, the anesthesia and
equipment storerooms and the entrances and the
exits.
• The highest clean-air requirements apply to the
operation area and the sterile preparation area.
• With respect to air treatment, the operating theatre
and a number of adjacent areas have to comply with
the provisions of the working conditions policy
regulation.
40. • From a technical point of view, the
protective effect of the air surrounding the
patient, operation team and instrument
table, can be achieved by installing a large
Laminar Air Flow (LAF) device(plenum).
• This LAF device with a down flow has a
surface area of 8 to 9 m2(e.g. square or
octagonal 3 x 3m, rectangular 2.8 x 3.2m).
41. • The air velocity from the down flow plenum is
24 to 30 cm/sec and flow temperature from the
LAF device is 1 to 2°C lower than the ambient
air.
• There are also possible solutions and
satisfactory results in environmental control
using special LAF devices in which the supplied
air has different speeds and temperatures and
which also improved the thermal comfort of
the surgical team.
42. • In order to be able to safeguard the
requisite air quality in the operating
theatre, a very large air flow is
necessary.
• A re-circulation down flow system
can be installed for this purpose.
43. • Part of the air from the down flow system
is re-circulated via fans to the HEPA filter
(HIGH EFICIENCY PARTICULATE AIR).
• POSSILE AIR CLEALIESS: The desired
germ level of less than 10 colony forming
units (CFU)per m3
• There must be no windows that can be
opened and outside walls must be
completely sealed.
44. Air Distribution
• Turbulent or mixing air distribution
system
• Downward displacement piston
system
• Unidirectional air flow system
(laminar flow)
45. The most important basic quality requirements
concerning spatial relationships are:
• The surgical department is independent of traffic
flows in the rest of the hospital; through traffic is
not permitted through this department.
• Airlocks physically seal a surgical department
from the rest of the hospital.
• Staff working in the operating theatre complex
can move from one ‘clean’ area to another
without needing to pass through ‘non-clean’
areas.
46. Other basic quality requirements
• The following basic quality
requirements apply to the use of
equipment & operational reliability
of installations.
• Health risks to staff such as exposure
to microbiological and chemical
Contamination, and lasers and
ionizing radiation can be avoided as
far as possible by drawing up
guidelines and protocols.
47. • Operational reliability of the technical
installations and an optimal
indoor environment for both patients and
staff form the basis for the design and
maintenance of the mechanical
engineering and electro technical
installations.
• The finish of floors, walls and ceilings
must be smooth, flawless or closed.
48. • Corners and transitions between floors and
walls will be rounded to prevent accumulation
of dirt.
• The different areas should be constructed and
furnished in such a way as to allow effective
cleaning and if necessary disinfection with
commonly used cleaning agents and
permitted disinfectants.

reflector to provide cool, bright and
homogenous illumination.
• OT Lights are made to spot light the operation
table area.
• They illuminate the area to the right level of
brightness
92. Types of air supply
Air is supplied to the operating theatre by:
1. Plenum Ventilation: This is the most frequently used system in
generalpurpose
• operating rooms. The bacterial counts at the wound site should
• be no more than 50 -500 colony forming units (cfu) per cubic meter.
2. Laminar Flow Ventilation (Ultra Clean Ventilation): This system is
• unidirectional and delivers air flow over the operating table of 300 air
• changes per hour. A bacterial count of 10 cfu or less per cubic meter at
• the wound site is achieved.
93. • 3. Wall Mounted Air Conditioners: These are installed in some tropical
• countries more for comfort than for clean air delivery. They should not be
• used as air delivery systems. The units are usually mounted on the hot
• outside wall and the air is directed down and back onto the unit itself
• (towards the wall). The operating table does not receive any significant air
• changes and the bacterial counts remain unaffected.
• 4. Free-standing Air Conditioners: These are cooling units with no
filtration
• of air and therefore do not fulfill the criteria for air delivery systems,
• especially for an OT.
94. Remember
• • Windows should remain closed.
• • The operating theatre should maintain at positive pressure.
• • Air should be introduced at the ceiling and should be exhausted near the floor
• in order to prevent bacterial contamination in the operative field.32
• • Air changes should be at least 20 changes per hour.
• • Air should first pass through a series of dust filters and then enter the room
• through a HEPA filter. Split-unit air conditioning is not allowed.
• • Humidity should be controlled and maintained between 50-55%.
• • Temperature should be controlled and maintained between 18-24 degrees
• Celsius.
