3. © 2007 McGraw-Hill Higher Education. All rights reserved. Bloodborne Pathogens  Pathogenic organisms, present in human blood and other fluids  cerebrospinal fluid, semen, vaginal secretion and synovial fluid can potentially cause disease  Most significant pathogens are Hepatitis B, C and HIV  Others that exist are hepatitis A, D, E and syphilis

4. © 2007 McGraw-Hill Higher Education. All rights reserved. Hepatitis B  Major cause of viral infection, resulting in swelling, soreness, loss of normal liver function  Signs and symptoms  Flu-like symptoms like fatigue, weakness, nausea, abdominal pain, headache, fever, and possibly jaundice  Possible that individual will not exhibit signs and symptoms -- antigen always present

5. © 2007 McGraw-Hill Higher Education. All rights reserved.  May test positive for antigen w/in 2-6 weeks of symptom development  85% recover within 6-8 weeks  Prevention  Good personal hygiene and avoiding high risk activities  Proceed with caution as HBV can survive in blood and fluids, in dried blood and on contaminated surfaces for at least 1 week  Vaccination against HBV should be provided by employer to those who may be exposed  Athletic trainers and allied health professionals should be vaccinated Hepatitis B

6. © 2007 McGraw-Hill Higher Education. All rights reserved.  Prevention (cont.)  Three dose vaccination over 6 months  Post-exposure vaccination is also available after coming into contact with blood or fluids Hepatitis B

16. © 2007 McGraw-Hill Higher Education. All rights reserved. HIV and Athletic Participation  No definitive answer as to whether asymptomatic HIV carriers should participate in sport  Bodily fluid contact should be avoided  American with Disabilities Act says athletes infected cannot be discriminated against and may only be excluded with medically sound basis  Must be based on objective medical evidence and must take into consideration risk to patient and other participants and means to reduce risk

17. © 2007 McGraw-Hill Higher Education. All rights reserved. Testing Athletes for HIV  Should not be used as screening tool  Mandatory testing may not be allowed due to legal reasons  Testing should be secondary to education  Athletes engaged in risky behavior should undergo voluntary anonymous testing for HIV  Multiple tests are available to test for antibodies for HIV proteins

18. © 2007 McGraw-Hill Higher Education. All rights reserved.  Detectable antibodies may appear from 3 months to 1 year following exposure  Testing should occur at 6 weeks, 3 months, and 1 year  Many states have enacted laws that protect confidentiality of HIV infected person  Athletic trainers should be familiar with state laws and maintain confidentiality and anonymity of testing Testing Athletes for HIV

19. © 2007 McGraw-Hill Higher Education. All rights reserved. Universal Precautions in Athletic Environment  OSHA (Occupational Safety and Health Administration) established standards for employer to follow that govern occupational exposure to blood-borne pathogens  Developed to protect healthcare provider and patient  All sports programs should have exposure control plan  Include counseling, education, volunteer testing, and management of bodily fluids

20. © 2007 McGraw-Hill Higher Education. All rights reserved.  Preparing the Athlete  Prior to participation, all open wounds and lesions should be covered with a dressing  When Bleeding Occurs  Athletes with active bleeding must be removed from participation and returned when deemed safe  Bloody uniform must be removed or cleaned to remove risk of contamination Universal Precautions in Athletic Environment

Skin Wounds  Types of wounds  Abrasions Skin scraped against rough surface Top layer of skin wears away Often involves exposure to dirt and foreign materials = increased risk for infection  Laceration Sharp or pointed object tears tissues – results in wound with jagged edges May also result in tissue avulsion  Incision Wounds with smooth edges

27. © 2007 McGraw-Hill Higher Education. All rights reserved.  Puncture wounds Can easily occur during activity and can be fatal Penetration of tissue can result in introduction of tetanus bacillus to bloodstream All severe lacerations and puncture wounds should be referred to a physician  Avulsion wounds Skin is torn from body = major bleeding Place avulsed tissue in moist gauze (saline), plastic bag and immerse in cold water Take to hospital for reattachment Skin Wounds

28. Abrasion Laceration PunctureIncision Avulsion

29. © 2007 McGraw-Hill Higher Education. All rights reserved. Immediate Care  All wounds should be treated as though they have been contaminated  To minimize infection clean wound with copious amounts of soap, water and sterile solution  Avoid hydrogen peroxide and bacterial solutions initially

30. © 2007 McGraw-Hill Higher Education. All rights reserved. Dressing  Sterile dressing should be applied to keep wound clean  Occlusive dressing are extremely effective in minimizing scarring  Antibacterial ointments are effective in limiting bacterial growth and preventing wound from sticking to dressing  Utilization of hydrogen peroxide can occur several times daily before reapplication of ointment

31. © 2007 McGraw-Hill Higher Education. All rights reserved. Are sutures necessary?  Deep lacerations, incisions and occasionally punctures will require some form of manual closure  Sutures should be used within 12 hours preferably a 4 hour window  Physician may decide wound does not require sutures and utilize steri-strips or butterfly bandages

32. © 2007 McGraw-Hill Higher Education. All rights reserved. Signs of Wound Infection  Same as those for inflammation  Pain  Heat  Redness  Swelling  Disordered function  Pus may form due to accumulation of WBC’s  Fever may develop as immune system fights bacterial infection

33. © 2007 McGraw-Hill Higher Education. All rights reserved. Signs of Wound Infection  Most wound infections can be treated with antibiotics  Staphylococcus aureus has become resistant to some antibiotics  Methicillin-resistant staphylococcus aureus (MRSA) is more difficult to treat and infection is extremely difficult to treat  If cause of infection is not discovered early and improper antibiotics are used initially, infection could spread into other aspects of the body

34. © 2007 McGraw-Hill Higher Education. All rights reserved. Signs of Wound Infection  Tetanus  Bacterial infection that may cause fever and convulsions and possibly tonic skeletal muscle spasm for non- immunized athletes  Tetanus bacillus enters wound as spore and acts on motor end plate of CNS  Following childhood vaccination, boosters should be supplied once ever 10 years  If not immunized, athlete should receive tetanus immune globulin (HyperTET) immediately following skin wound
