  1. HYGIENIC AND PREVENTIVE PROCEDURES Dragica Kopić, MD Department Of Anesthesiology and Intensive Treatment, University Hospital Split, Croatia

  2. The principal task of health care institution • To provide a good health care service • To prevent hospital infection; and • To prevent hospital infection transmission and spreading

  3. Transmission of infection from patient to health care workers, and the other way around, occurs: • By direct contact and touch • By fecal - oral transmission (food and drink) • By air (inhalation) • By blood

  4. The infections are caused by: • bacteria, • viruses, • fungi … • They are present in: • water, • air, • patient’s environment, and • Patient can be a source of infection, too.

  5. Asepsis • Method we use to control microbes transmission • from one place to another, • from one patient to the other one, or • from patient to health care workers. • To achieve asepsis we use: • disinfection • sterilization

  6. Disinfection • The process of destroying majority of microorganisms • Bacterial spores may survive and contaminate • Highly effective disinfectants, acting in prolonged time (6-10 h) can eliminate bacterial spores.

  7. Disinfection techniques are applied on: • Health care providers’ hands • Patients’ skin and mucous membranes • Instruments and equipment • Working surfaces, floors, walls • Air in rooms • All patients’ requisites and equipment • Patients’ clothes, health care workers clothes and footwear.

  8. Self protection measures • Regular and proper hand cleaning • Appropriate use of protective clothing and footwear • Appropriate use of masks and gloves • Appropriate handling of sterile materials

  9. Hand cleaning • This is the most important and the most effective preventive method against spreading microbes between health care workers and patients in the hospital. • The basic condition for proper hand hygiene is that nails do not overgrow finger cushion. • Jewelry and long artificial nails are strictly prohibited

  10. Hand cleaning • There are three levels of hand cleaning: • – standard, • – hygienic disinfection , • – surgical disinfection.

  11. Standard hand washing • Hands have to be cleaned: • Before handling food • Before meal • Before feeding patient • After use of bathroom Swab taken of unwashed hands

  12. Standard cleaning • Hands are washed in hot water and with soap over one minute period. Swab from washed hands

  13. Hygienic hand disinfection or antisepsis • Before and after dealing with patient • Before performing invasive procedure • Before and after wound dressing, handling urinary catheters, tubes, iv lines etc. • Before and after gloves usage • After contact with blood and other patient secretions and excretions • After contact with patient with know hospital bacterial colonization

  14. Hand disinfection is made in two steps • Hygienic hand washing with antiseptic soap over one minute period • Hygienic scrubbing with alcohol based antiseptic lasting one minute.  Swab after hand desinfection

  15. Surgical hand antisepsis • Goal of surgical disinfection or antisepsis is to eradicate microbes. • Procedure of surgical hand cleaning is in principle the same as hygienic disinfection • The difference is in duration of hand washing, surgical one lasts longer, 2-3 minutes, and • The are to be washed is larger, includes wrists and forearm • Common antiseptic substances are chlorinebased antiseptics - chlorhexidine; iodine based and alcohol based ones.
