Sterile - means free of microorganisms

including the pores.

Asepsis- means absence of

microorganisms that cause disease.


3/29

Medical Asepsis

practices designed toreduce the numbers of pathogenic

microorganisms in the clients environment

Sterile Asepsispractices that are used to

prevent the introduction of

microorganisms that could cause infection


4/29

Sterile techniques - are methods

employed inside the operating room to

prevent contamination of organisms

throughout the surgical procedure.

6/29

Preparation for an invasive procedure

In preparation of the sterile team to

handle sterile supplies and contact to the

surgical site (gowning, gloving and

scrubbing)


7/29

Skin preparation and draping of the

patient

Sterility maintenance throughout the

operation

Principle Number 1:

Only sterile items are used within thesterile field.


10/29

Drapes, basins, sponges are obtained from

a stock room with sterile packages. The

instruments used are sterilized and are

placed in a sterile table.

Any person who holds the sterile

equipments should be very cautious to

maintain sterility.


11/29

One important consideration in implementingsterility is this:

IF YOU ARE IN DOUBT ABOUT THE STERILITY

OF A CERTAIN OBJECT, CONSIDER ITUNSTERILE. Any suspected or known

unsterile items should not be placed the

sterile field.


12/29

Principle Number 2:

Sterile persons are gowned and gloved.


13/29

When wearing a gown, the consideredsterile area is the part where you can see in

front down to the level of the sterile field.

Thus, gowns are only considered sterile in

front of the chest, sleeves above the elbow

to the cuffs down to the level of the sterile

field.


14/29

Principle Number 3:

Tables are only sterile at Table Level

Principle Number 4:Sterile Persons Touch ONLY Sterile Items

while Unsterile OR Personnel Touch Only

Unsterile Items


15/29

Principle Number 5:

Unsterile persons avoid reaching over sterile

field and sterile persons avoid touching or

leaning over an unsterile area.

Principle Number 6:

Edges of anything that encloses sterile contents

are considered unsterile


16/29

Principle Number 7:

Sterile field is set-up just before a surgical

Principle Number 8:

Sterile areas are continuously kept in view.


17/29

Principle Number 9: Sterile persons keep well within sterile area.

Principle Number 10:

Sterile persons keep in contact with sterile areasto minimum.


Unsterile persons avoid sterile areas


18/29


Destruction of integrity of microbial barriers

result in contamination


19/29

A sterile packages integrity is destroyed by

the following instances:

Perforation

Puncture

Strike-through soaking of moisture

through unsterile or sterile layers or vice

versa.


20/29

Before opening a sterile package to be used

in a certain procedure or operation the

package should be checked thoroughly

before opening.


21/29


Microorganisms must be kept to

irreducible minimum


22/29

Sterilization is the process of removing

ALL microorganisms including the bacterial

spores. However, not all things or area

can be sterilized.


23/29


24/29

Skin cannot be sterilized thus, it can be verygood source of contamination in any

operation. To prevent entrance of

microorganism to the patients wound thefollowing are done:


25/29

Surgical hand washing

Chemical antisepsis of the skin around the

surgical site

Gowning and gloving

Application of sterile draping.


26/29


27/29

Air contains dust, droplets and shedding

that may cause contamination.

Environmental control measuresinclude:


28/29

Movement around the sterile field is kept

to a minimum.

Drapes are not flipped and fanned to avoid

the spread of dusts.

Talking inside the operating room is kept to

a minimum because moisture droplets are

expelled with force into the mask when a

person is talking.
