1a) Asepsis and its principlesin healthcare facilities
Definition
complete absence of microorganisms and germs,
antisepsis is achieved by means of sterilization (aseptic = sterile).
Related terms
Antisepsis
a set of measures and procedures,
the aim is to destroy infections on the surface of the body, mucous membrane and in tissues of the human body,
antisepsis is ensured by the application of antisepticon the surface of the body or into body cavities, into the wound.
1a) Asepsis and its principlesin healthcare facilities
Related terms
Disinfection
destruction of most microorganisms on inanimate objects, materials, surfaces, in the air or water,
the aim is to interrupt the path of infection from the sourceto susceptible individual,
unlike antisense during disinfection, we can use relatively toxic agents, since disinfection is not performed on living tissuesof the organism.
Sterilization
a set of measures leading to the removal or destruction of all microorganisms and higher organisms and / or its possible forms.
1a) Asepsis and its principlesin healthcare facilities
Asepsis technique
working method to prevent the spreadof infection and to achieve antisepsis.
Basic asepsis procedures
hygienic hand washing and disinfection of hands beforeand after direct contact with the patient,
use of protective equipment,
contaminated material stored in containers designed for this purpose,
careful handling of tools as the prevention of injuries,
provide a sterile environment during invasive procedures.

1a) Asepsis and its principlesin healthcare facilities
Basic asepsis procedures
observing of the skin surface of the patient and his vital signs,
pressure ulcer prevention and treatment,
isolation of patients with infectious diseases,
providing of optimal food and fluid intake,
education of the patient and family,
compliance of barrier care.

1b) Nosocomial infections
1b) Nosocomial infections
these infections are directly connected with the stay in a hospital environment,
they are an important indicator of quality of care,
nosocomial infections can affect not only patients' but also medical staff.
Division
by occurrence - specific X nonspecific,
by origin - exogenous X endogenous,
according to the clinical display.
1b) Nosocomial infections
Division by occurrence
Nonspecific nosocomial infections
infections that occur commonly outside the medical facilities,and the are also present in healthcare facilities due to the epidemiological situation in the region (e. g. flu),
infectious agents are usually well sensitive to antibiotics.
Specific nosocomial infections
they arise in a hospital environment in connection with diagnostic or therapeutic procedures,
they are characterized by the proliferation of specific, often highly resistant originator, different approaches to prevent and treat compared to hospital infections.
1b) Nosocomial infections
Division by origin
Exogenous nosocomial infections
the infectious agent is outside the body of the patient (staff, polluted air, material ...).
Endogenous nosocomial infections
they are caused by the patient's own microbial flora,
infectious agent is brought from the colonized organ or mucosal surface into the surrounding tissue or to another organ(e. g. intestinal microorganisms into the abdominal cavity).
1b) Nosocomial infections
Division according to clinical display
urinary tract infection (approximately 40 %),
infection spread to surgical wounds (approx. 25 %),
respiratory infection – pneumonia (approx. 20 %),
bloodstream infections – bacteremia (approx. 10 %),
others – e. g. gastroenteritis, sinusitis (to 10 %).
1b) Nosocomial infections
Transmission routes
Direct – source of infection is present:
direct contact – most hands of personnel,
droplet infection.
Indirect – source of infection is not present:
nonspecific carrier – air, water, food, clothes…,
specific carrier– surgical wounds, parenteral administrationof medication, catheterization, mechanical ventilation, etc.

disease… ), nutritional status (malnutrition, obesity, alcohol, smoking, drugs..), diagnostic and therapeutic procedures (iv inputs, urine
catheterization. bladder, surgical drains, tracheotomy... ), trauma (injuries, burns, pressure ulcers... ), specific treatment (cytostatic, antibiotics, steroids... ), length of hospitalization.
1b) Nosocomial infections
Prevention
washing and hand disinfection, use of protective equipment, adherence to the principles for handling laundry, decontamination of biological material, sanitary handling of food, individualization of equipment/tools, isolation of infectious patients, or those who are at risk of infection, prevention of infectious aerosols with appropriate cleaning
procedures, cleaning and disinfection of the environment.

hygienic hand washing and hand disinfection,
use of protective equipment,
purity (personal, environmental, patient),
a small number of patients in the room,
use of individual devices for patients.
1c) Barrier care
Basic rules of barrier care:
decontamination of biological material, used equipment, instruments, medical supplies…,
adherence to aseptic procedures during dressing changes,
adherence to the principles for handling linen (clean and used),
sanitary handling of food,

1e) The use of gloves
1e) The use of gloves
The use of disposable gloves
- gloves are protective equipment that:
provides mechanical barrier, ↓ the risk of transmission of infection
from medical staff to patients and frompatients to medical staff,
↓ the risk of contamination of the hands of medical staffwith biological material.
Rules of the use of disposable gloves:
perform hygienic hand disinfection before sliding it ontothe glove,
put gloves after the disinfectant is dry.
*
1e) The use of gloves
Rules of the use of disposable gloves: always use gloves, if there is a potential risk of contamination
by biological material,
gloves do not replace hand hygiene,
clean pair of gloves for each patient,
changing gloves when contamination even when taking care of one patient (e. g. hygienic care before performing dressing... ),
gloves undress immediately after the activity for which they were used,
do not use damaged gloves,
used gloves dispose of as infectious material,
gloves do not provide complete protection against contamination,it is required to do sanitary disinfection and hand washing after using gloves.
1e) The use of gloves
The use of sterile gloves
Indication:
surgery,
invasive radiological procedures,
the provision of central vascular access,
performances regarding cavities (with the exception of naturally non-sterile body cavities), e. g. bladder catheterization,

• ways of handling sterile material
• principles of handling sterile material
1f) Handling with sterile material
1f) Handling with sterile material
We distinguish between two ways of handling sterile material:
1. Administered way– surgical instruments are placed in sterile packs, they are pulled out with sponge holding forceps.
2. Non-administered way– surgical instruments or materials are individually packaged.
1f) Handling with sterile material
Rules: the manipulation of sterile material is treated after hygienic hand
washing or disinfecting hands and in clean work clothes,
sterile material is removed from a drum or container right before its using,
we pull out sponge holding forceps from quivers in the middle of the quiver, we can not touch the quiver,
we administer the tools with grasping part,
we hold a tampon in sponge holding forceps on the edge,
we must never put hands into the cassette,
we hold the sterile sponge holding forceps above the waist,
sterile material is added into the sterile field from a height of 10-15 cm.
1f) Handling with sterile material
Rules:
a cap of cassette is put down the outer pad and it is closedas quickly as possible,
swabs are soaked into a sterile solution only once,
sterile material, that is removed from the drum or container,we can not get back even if it was not used.
• indications for preparing sterile field
• basic tools
• the procedure for preparing sterile field
1g) Preparation of sterile spacefor asepsis procedures
Indications for preparing sterile field:
the introduction of vascular inputs (central venous catheter, arterial catheter),
tracheostomy,
thoracic drainage,
minor surgical interventions,
more extensive wound dressing,
surgeries etc.
1g) Preparation of sterile spacefor asepsis procedures
stainless steel containers for surgical instruments
Basic tools:
surgical mask + hat,
sterile gloves,
sterile gown,
basic surgical instruments (tweezers,hemostats, scissors),
sterile swabs and squares,
2 syringes (10 ml),
needle and suture,
bowl for saline.
Other tools depending on the type of performance.
1g) Preparation of sterile spacefor asepsis procedures
1g) Preparation of sterile spacefor asepsis procedures
Steps:
check the integrity of the table and if it is possible to adjustthe height of the desktop,
mechanically clean the table and disinfect it,
Put surgical mask back to front on the table,
Put needed tools on the set table from a height of 10 - 15 cm,
2.5 cm from the edge masks are considered non-sterile,
if you need to move a cart, touch only the lower part,
if needed (a surgery is not performed immediately), coverthe prepared table with a sterile drape, which is put front to back.
