760. Frage
One of a surgeon's worst fears includes bacterial contamination during surgery. As a surgery technician, your job is to minimize the risk of bacterial contamination. Which of the following factors is most consistently documented to influence the incidence of wound contamination and subsequent infection?

Antwort: B

Begründung:
Technically speaking, all of the answer choices may lead to bacterial contamination. However, the highest incidence occurs regardless of other factors the longer the anesthetic procedure and event takes.
Exogenous sources of contamination of concern include the air we breathe, the supplies used and the surgical instruments, the patient's skin, and all surgical team members. Studies suggest that the risk of infection doubles for each additional hour the pet remains under anesthesia. Thus, ensuring all equipment and personnel practice aseptic techniques and instruments are properly sterilized, efficiency and effectiveness are key. The surgical team can minimize exogenous wound contamination and prevent infection through strict aseptic practices and procedures.
Endogenous sources can occur via the bloodstream (bacteremia). The presence of gingivitis or dermatitis may be sufficient to create endogenous sources of contamination.
