    Q. Preoperative preparations with your scrub team are under way prior to performing a thoracotomy for persistent pneumothorax on a patient who is known to have AIDS. Which statement about transmission of HIV in the health care setting is true?

    a- A freshly prepared solution of dilute chlorine bleach will not adequately decontaminate clothing
    b- All needles should be capped immediately after use
    c- Cuts and other open skin wounds are believed to act as portals of entry for HIV
    d- Double gloving reduces the risk of intraoperative needle ticks
    e- The risk of seroconversion following a needle stick with a contaminated needle is greater for HIV than hepatitis B

    Answer: c. (Rhame, Postgrad, Med 91:141-152, 1992) the risk of contracting HIV is much less than the risk of contracting hepatitis B from a patient. Although the risk of transmission of HIV in the health care setting is very low, there re reported cases seroconversion after parenteral exposure. Particular precautions should be taken in operating on patients who are known to be seropositive for HIV or who have known risk factors. Recommendations include elimination of inexperienced personnel or personnel with open lesions on body surfaces from the operating room. Disposable gowns, drapes, masks, and eye shields should be used. Contaminated clothing should be soaked in a dilute solution (1:10) of chlorine bleach prior to washing. Double gloving does not reduce the major intraoperative risk of needle puncture, which is the primary source of risk to the operating team. Needles should never be capped; an uncapped needle is less dangerous than are the maneuvers to recap needles.
