Sterilization


  • STERILIZATION is a method that ensures the death of vegetative and spore forms of pathogenic and non-pathogenic microorganisms in the sterilized material.
  • All items or certain types of diagnostic equipment that come into contact with wounds, blood, injections, and damaged mucous membranes should be sterilized.

Sterilization steps

Products to be sterilized are processed in several stages:

  • Cleaning;
  • Disinfection;
  • Pre-sterilization cleaning;
  • Sterilization.

In modern educational institutions, centralized sterilization departments (CSO) are organized, in which they carry out:

  • Pre-sterilization processing of medical instruments;
  • Sterilization:

A) medical products;

B) linen and dressings.


Pre-sterilization treatment

The purpose of pre-sterilization treatment is to remove protein, fatty, medicinal, mechanical contaminants (including blood, mucus) from medical devices, which ensures the effectiveness of subsequent sterilization and the safe use of sterilized products.


Pre-sterilization treatment methods

Pre-sterilization processing is carried out manual and mechanized ways.

Manual way:

Stage 1 - rinsing after disinfection with running water for 30 seconds until the odor of the disinfectant is completely removed.

Stage 2 - soaking the product in detergent - 15 minutes.

Stage 3 - washing each product in the same solution in which it was soaked using a brush for 30 seconds.

Stage 4 - rinsing with running water.

Stage 5 - rinsing with distilled water for 30 seconds.

Stage 6 - drying with hot air at a temperature of 75-85 o С in drying ovens


Methods, means and modes of sterilization

The following sterilization methods are used:

  • Thermal (steam, air);
  • Chemical (gas, chemicals);
  • Radiation;
  • Plasma and ozone (a group of chemicals).

The choice of a particular sterilization method for specific products depends on the characteristics of the product and the method itself - its advantages and disadvantages.

The most common methods in health care facilities are steam and air.


Steam sterilization method

The sterilizing agent is hot steam under pressure. An autoclave is used for this method.

Packaging: bix, kraft bags, laminated paper, coarse calico.

Materials: polymers, glass, latex, fabric, corrosion-resistant metals.

Advantages: high vapor permeability, a large selection of packaging, sterility remains longer, a cheap and easy-to-use method.

Disadvantages: wetting of products, corrosive to metals.


Air sterilization method

Dry heat ovens are used for this method.

The sterilizing agent is dry hot air (160-200 o C).

Packaging: kraft bags, coarse calico.

Materials: metal, textiles.

Advantages: a cheap, simple method, does not cause metal corrosion, does not wet the packaging and products.

Disadvantages: limited choice of packaging, slow and uneven heating of products, the need to use higher temperatures, the inability to use materials from rubber, polymers.


Gas sterilization method

Gas sterilizers are used for this method.

The sterilizing agent is formaldehyde or ethylene oxide.

Packaging: laminated paper, parchment, kraft paper.

Materials: polymers, glass, metal.

Advantages: low temperature, use of any materials.

Disadvantages: toxicity to personnel and explosion hazard if safety precautions are not followed, long sterilization cycle.


Radiation sterilization method

The radiation method is necessary for the sterilization of products made from thermolabile materials.

Sterilizing agent - ionizing γ and β radiation.

Packaging: in addition to paper bags, polyethylene bags are used.

Advantages: sterility in the package remains for a long time.

Disadvantages: high cost of the method.

Radiation is the main method of industrial sterilization. Used by enterprises producing sterile disposable products.

Introduction One of the most important areas of work of all medical personnel is the provision and control over the implementation of sanitary-hygienic and anti-epidemic measures and the requirements provided for by the relevant orders of the Ministry of Health of the Republic of Kazakhstan. Sterilization is the process of killing all types of microorganisms, as well as spores and bacteria.

Sterilization methods approved for use in health care facilities Physical (thermal) Steam-Water saturated steam under excess pressure Air-Dry hot air Infrared-Infrared radiation Glasperlen-Medium of heated glass beads Chemical, Gas-Ethylene oxide or its mixture with other components Plasma -Vapors hydrogen peroxide in combination with their low-temperature plasma Liquid -Solutions of chemical agents (aldehyde-, oxygen- and chlorine-containing)

Stages of sterilization 1) Disinfection is a set of measures aimed at destroying pathogens of infectious diseases and destroying toxins on environmental objects. Disinfection reduces the number of microorganisms to an acceptable level, but it may not completely destroy them. 2) Pre-sterilization treatment is the cleaning of medical devices before their sterilization, in order to remove protein, fat and mechanical contaminants, as well as drugs. 3) Sterilization is the complete destruction of all forms of microbes and their spores under the influence of high temperatures and other physical factors, chemicals, ionizing radiation.

Products to be sterilized 1) Medical and laboratory instruments of all kinds are subject to disinfection after each use. 2) All medical devices that come into contact with the skin and mucous membranes, organs, wound surfaces, contact with blood and other biological fluids are sterilized. 3) Disposable instruments (syringe, systems, scarifiers, spatulas, gynecological mirrors) are disposed of by burning in special or muffle furnaces at a temperature of at least 6000 C

Disinfection methods 1) Boiling Applied: for glassware, metal, heat-resistant polymer materials, rubber. 2) Steam Applied: for glass, metal, heat-resistant polymer materials, rubber, latex. Note: During disinfection by boiling and steam method, products made of polymeric materials should be packed in gauze 3) Air Applied: for glass and metal products. 4) Chemical Applied: for glass products, corrosion-resistant metals, heat-resistant polymer materials, rubber. Note: After chemical disinfection, products should be rinsed in running water until the odor of the disinfectant is completely removed.

Pre-sterilization treatment Algorithm of actions: 1) Upon completion of disinfection, medical instruments are rinsed with running water for 30 seconds. Then they are soaked with full immersion in a detergent solution at a temperature of 20-250 C for 15 minutes. 2) Washing each product in a detergent solution using a brush or cotton-gauze swab for 30 seconds. 3) Rinsing with running water for 10 minutes. 4) Rinsing with distilled water for 30 seconds 5) Drying with hot air in a drying oven at a temperature of 850 C until moisture completely disappears.

Types and methods of sterilization 1) Chemical method of sterilization This method is recommended for products made of polymer materials, rubber, glass, corrosion-resistant metals. It is carried out when the product is completely immersed in the solution, after which the product is rinsed with sterile water. The shelf life of a sterile product in a sterile container lined with a sterile sheet is 3 days. For immersion of products in des. the solution should be used in containers made of glass, plastic or enamelled 1) 6% hydrogen peroxide solution t = Not less than 18 0 С for 360 min 2) 10% gigasept solution for 300 min 3) 2, 5% solution of lysoformin-3000 t = 40 -50 0 С for 60 min 4) Sidex activated 2% solution of glutaraldehyde with p. H = 8, 2 -9, 2 t = 20 -25 0 С for 240 min 5) Glutaraldehyde 2, 5% p. H = 7, 0 -8, 5 t = Not less than 20 0 С during 360 min

2) Steam sterilization method Sterilization is carried out in sterilization boxes without filters or in sterilization boxes with a filter or in double soft packaging made of coarse calico or parchment, sack paper, non-impregnated wet-strength sack paper, paper for packaging products on machines of E grade, paper creped in a steam sterilizer ... The shelf life of products sterilized in boxes with a filter is 20 days, in the rest of the packaging - 3 days Sterilization mode Steam pressure, kg / cm 2 0, 11 Working temperature, 0 С 132 120 Holding time, min Applicability 20 Recommended for products made of corrosion-resistant metals, glass, rubber products 45 Recommended for products made of rubber, latex and certain polymeric materials (high density polyethylene, PVC

3) Air sterilization method Sterilization is applied to dry products, and it is carried out in packaging made of non-impregnated sack paper, wet-strength sack paper, paper for packaging products on machines of E grade, high-strength packaging paper, crepe paper, double-layer crepe paper or without packaging in an open container in air sterilizer Unpacked sterilized products are used immediately after sterilization, packaged - within 3 days. Sterilization mode Applicability Operating temperature, 0 С Holding time, min 180 60 150 Recommended for metal, glass and silicone rubber products

Sterilization control methods 1) Physical and chemical The parameters of the operating mode of sterilizers are monitored chemical methods are based on the color change of indicators upon reaching a certain temperature 2) Bacteriological Sterilization efficiency is assessed

Software control is carried out using the following tests: 1) Azopyram test is carried out for the presence of hemoglobin, oxidants, chlorine-containing substances, washing powder, rust. Prepare 1, 0 -1, 5% solution of hydrochloric acid aniline in 95% alcohol. It is stored in the refrigerator for up to 2 months, outside it - no more than a month. Before setting the sample, mix equal volumes of azopyram and 3% hydrogen peroxide. Use the mixture within 1-2 hours. Do not check hot tools, do not keep solution near heating devices and in bright light. When a blood stain is contacted with reagent, a violet color appears within one minute.

2) Amidopyrine test is performed for the presence of blood. Mix equal amounts of 5% alcohol solution of amidopyrine, 505 acetic acid and 3% hydrogen peroxide solution (2-3 ml each). Apply 2-3 drops of the reagent to the controlled item. In the presence of blood contamination, a blue-green color appears (exposure 3 minutes 3) Phenolphthalein test is carried out to check the quality of washing the active substances of the washing instrument from the surface of the instrument. Apply 1% phenolphthalein solution. If present, a pink coloration occurs.

modern effective
methods of pre-sterilization
processing and sterilization

The CSO should have two zones:
non-sterile and sterile.
The non-sterile area includes the "dirty"
and "clean".
The "dirty" zone includes:
reception and disassembly rooms
medical devices
washing room - the room is intended for
carrying out PSO products
auxiliary premises - wardrobe,
staff rest and meal room,
showers

A "clean" area is an area where
produced:
drying
quality control of cleaning
parsing, sorting, composing
sets
packaging and preparation for sterilization
products

Sterile area

includes:
unloading side of steam,
dry air and other
sterilizers
warehouse of sterile materials

When planning premises
it is advisable to envisage
organization of two processing streams:
1st stream - processing and sterilization
tools, rubber products.
2nd stream - preparation and sterilization
linen and dressings.
CSO is equipped with supply and exhaust
ventilation and bactericidal
lamps.

Pre-sterilization cleaning (PSO) of medical devices Second stage of instrument processing

PSO is used for cleaning products
medical supplies from
protein, fat, blood,
medicinal and other
pollution.
The quality of the USAR team directly affects
quality of sterilization.

PSO stages (manual method):

Soaking medical instruments
appointments in detergent solution 15 minutes
Mechanical processing with a brush,
cotton swab (30 seconds each)
removing from the solution, clean the needles
mandrin
Rinsing under running water at
using SMS "Biolot" - 5 min., others
7-10 minutes ("Astra", "Progress")
Rinsing in distilled water 30
seconds
Drying in a dry heat oven (85 0) to
complete disappearance of moisture
PSO control

The quality of the pre-sterilization
cleaning is carried out by samples:
for blood residues, disinfectants, SMS,
rust
- azopyramic - universal
- phenolphthaleic - for presence
leftover SMS
- amidopyrine - for blood residues
- Sudan 3 - for the presence of fatty and
protein residues

Result evaluation

2-3 drops of the reagent are applied to the controlled item and
rub it with a swab. With a positive azopyram test
a purple color appears, quickly, within a few
seconds, turning into pink-lilac and brownish. Coloring,
occurring later than 1 minute is not taken into account. Brownish
staining appears in the presence of rust and
chlorine-containing oxidants, otherwise staining
pink and lilac.
Phenolphthalein test in the presence of unwashed components
synthetic detergents gives a pink coloration.
With a positive amidopyrine test, a blue-green color occurs.
With positive samples, the entire batch of controlled
products must be re-processed before receiving
negative results.
The control results are reflected in the form No. 366 / U, approved by
by order of the Ministry of Health of the USSR on 04.10.1980. No. 1030 "Journal of quality accounting
pre-sterilization treatment ".

Subject to control: in the CSO - 1% of
of each product name, but not
less than 3-5 units.
In case of a positive sample
(reagent color change) all
a batch of products is subjected to
re-cleaning. results

plastics. He is strong
bactericidal, sporicidal and virucidal
means. His couples have a high
penetration. carried out at
low temperatures (18-80 ° С) and products
sterilized in packaging.
Disadvantages: toxicity to personnel and
explosion hazard in case of non-observance of the technique
security.

Gas sterilization

Cold sterilization method

Radiation method
The sterilizing agent is ionizing
gamma and beta radiation. Object temperature at
sterilization rises slightly, therefore
this method is called cold sterilization.
For individual packaging in addition to paper,
use polyethylene bags. Sterility in
such packaging lasts for years. Shelf life
indicated on the packaging. This way is widely
used in industrial plants,
manufacturing medical devices
single use (systems for
blood transfusions, obstetric kits).

Cold sterilization method

With plasma sterilization method
use high-frequency plasma in
domestic devices "Plaster", "Feruso".
For processing products from heat-sensitive
materials (endoscopes, pacemakers,
optical devices, endoprostheses, etc.)
the Sterrad 100-8 sterilizer is used.
This method is used for sterilization
small-sized medical devices
(dental burs, needles for
acupuncture, etc.).

reactor sterilizer.
Sterilization holding time 50 minutes,
ozone deactivation time 10 minutes.
Ozone sterilizer (СО-01-С or СО-5)
refers to low-temperature (temperature
40 ° C), used for sterilizing dry
scalpels, tweezers, mirrors, probes, spatulas,
dental burs in unpackaged form,
placed in 1 layer in a cuvette.

Ozone sterilizer

Chemical sterilization

Performed in closed containers,
covered with intact enamel, and
also made of glass or
plastics.
The objects to be sterilized are immersed in
solution at a temperature of 18 ± 2 °.
For sterilization, the instruments are completely
immersed in open (or disassembled)
form in one of these solutions.
When soaked in alcohol and triple
mortar tools are considered
sterile after 2-3 hours, in peroxide
hydrogen - after 6 hours.

Gas method

When sterilizing food
products, medicines
and various kinds of devices, as well as in
laboratory practice justified
the application of ethylene oxide ourselves,
which kills and vegetative
cells, and spores, but only acts in
if the subject
sterilization materials contain
some amount (5-15%) of water.
Ethylene oxide is used in the form
gas mixture (with N2 or CO2), in
which its share ranges from 2 to 50%.
The ethylene oxide method provides
the most gentle temperature
sterilization mode.

Gas sterilization method

Sterilizing agent -
formaldehyde or ethylene oxide.
Packaging: laminated paper,
parchment, kraft paper.
Materials: polymers, glass,
metal.
Advantages: low
temperature, use of any
materials.
Disadvantages: toxicity for
personnel and explosion hazard when
non-observance of safety precautions,
long lasting
sterilization cycle.
Gas sterilization method

Cold sterilization methods

Plasma method

allows you to create a biocidal
environment based on water
hydrogen peroxide solution,
as well as low-temperature
plasma (ionized
gas generated by
low pressure).
This is the most modern method
sterilization known at
present day. He
allows sterilization
any medical products,
from hollow instruments to
cables, electrical appliances, to
which in some cases
fails to apply at all
none of the known
sterilization methods.

Plasma sterilizers

Radiation method

Antimicrobial treatment can be carried out with
using ionizing radiation (y-rays),
ultraviolet rays and ultrasound. The greatest
application in our time has received sterilization uchas.
Radiation method or gamma ray sterilization,
used in special installations in industrial
sterilization of single use - polymeric
syringes, blood transfusion systems, Petri dishes,
pipettes and other fragile and heat-sensitive products.
The isotopes Co60 and Cs137 are used. Penetrating dose
radiation should be very significant - up to 20-25
μGy, which requires compliance with particularly stringent measures
security. In this regard, radiation sterilization
held in special rooms and is
factory sterilization method (directly in
it is not produced in hospitals).

Radiation sterilization method

The radiation method is necessary for sterilizing products
from thermolabile materials.
Sterilizing agent - ionizing γ and β radiation.
Packaging: in addition to paper, bags made of
polyethylene.
Advantages: sterility is maintained for a long time
packaging.
Disadvantages: high cost of the method.

Sterility assurance principles:

Only touch a sterile item with others
a sterile item to avoid contamination.
Always keep sterile items above your waist.
The sterile field must always be within sight.
Try not to talk, cough, sneeze, or
bend over a sterile surface as
the resulting air flows contain
microorganisms.
The border zone around the sterile field with a width of about
2.5 cm is considered potentially infested.
Do not allow wipes to get wet over sterile
surface, since any liquid penetrates through
tissue, and with it microorganisms.
If a sterile object touches a non-sterile one, everything
the sterile field is considered contaminated and prepared
new sterile field.
Consider an item as contaminated if you are unsure about it
sterility.

The indicators are a rectangular strip of
inert paper base coated on one
side with two colored marks (Fig. 1) - indicator 4 and
comparison standard 5, and labeling. For gluing
the indicator is necessary from its back side under the inscription
"Date", separate the left part of the security paper 1 (Fig. 1) by
notch line 2 glue the left side of the indicator to the line
perforation 3 to the package. In this case, the right side of the indicator
does not stick.
To remove the indicator from the packaging after sterilization
it is necessary, without separating the protective paper 1, to tear off
indicator along the perforation line from the glued left
parts. Glued left side of the indicator with service
inscriptions are not removed from the packaging and reaches
consumer, which allows you to control the multiplicity
using paper packaging material
