  8. Biological hazards bloodborne pathogens airborne biological agents droplets containing infectious biological agents environmental biological contaminants

  9. Ergonomic hazards • associated with patient handling • associated with computer use • associated with material handling of equipment, furniture and supplies including lifting, carrying, pushing, pulling, etc. • associated with positioning and holding limbs, equipment, etc.

  10. Nervous-emotional strain

  11. Occupational Hazards in the Operating Room

  12. Hazards of surgeon work • Unfavorable microclimate • Contaminated air • High risk of trauma

  13. Hazards of surgeon work • A break of work and rest regimen • Working upright posture • Hard physical work

  14. Overstrain of a working hand

  15. The increased strain of vision

  16. Hospital acquired infections Hospital acquired infection is also called Nosocomial infection or Healthcare-associated infection nosocomial “nosus” = disease “komelion” = to take care of

  17. Condition of HAI spreading

  18. Prevalence of HAI • diseases of upper respiratory organs, children’s infections • staphylococcal and streptococcal infections of the skin, hypodermic cellular tissue, mucous membranes, post-operative suppurative inflammatory complications, septic diseases • intestinal infections

  19. Sources of HAI

  20. Сost of HAI treatment

  21. Risk factors of HAI with multiresistant pathogens • Advanced age • Underlying disease • Severity of illness • Transplantation • Gastrointestinal surgery • Exposure to medical devices • Heavy exposure to antimicrobial therapy • Prolonged hospital stay • Interinstitutional transfer of patient

  22. Prevention of HAI transmission • Nonspecific measures : architectural planning, sanitary and technical, sanitary and antiepidemic, disinfection and sterilization measures. • Specific measures : planned • and urgent specific prophylaxis

  23. General Recommendations for Control and Prevention of HAI transmission • Regular hand washing after contact with patients or surfaces in a hospital • Regular disinfection of potentially contaminated surfaces and equipment • Surveillance cultures necessary for infection control purposes for specific organisms such as VRE • Alcohol-based hand washing liquids • Antibiotic formulary intervention or restriction
