Question

The primary source of airborne bacteria transmission in the OR is the __?

A) Surgical instruments
B) Air ventilation system
C) Healthcare personnel
D) Patient's clothing

Answer 1

Healthcare personnel are the primary source of airborne bacteria transmission in the OR, contributing to nosocomial infections via aerosols produced through activities such as coughing, sneezing, and talking.

Step-by-step explanation:

The primary source of airborne bacteria transmission in the operating room (OR) is C) Healthcare personnel. Though bacteria can be introduced into the OR environment through various means, including contaminated medical devices such as ventilators and intubation equipment, the movement and activity of healthcare personnel typically generates a significant amount of airborne bacteria.

These individuals are in constant motion, shedding skin cells, and bacteria, particularly when proper aseptic techniques are not followed meticulously. Studies have shown that even simple actions such as coughing, sneezing, or talking can produce aerosols carrying bacteria that can contribute to nosocomial or healthcare-associated infections. Therefore, diligent adherence to hygiene practices and protocols is crucial in minimizing the risk of bacterial transmission in surgical settings.

Answer 2

The primary source of airborne bacteria transmission in the OR is healthcare personnel. While all options could potentially contribute to bacterial spread, properly maintained medical equipment and ventilation systems typically prevent such issues. Healthcare personnel are consistently active in the OR environment and may shed bacteria despite sterile procedures. The correct option is C) Healthcare personnel.

Step-by-step explanation:

The Primary Source of Airborne Bacteria Transmission in the Operating Room

The question inquires about the primary source of airborne bacteria transmission in an operating room (OR). In the settled and procedure-driven environment of an OR, a variety of sources can contribute to the transmission of airborne bacteria, which can potentially result in nosocomial infections. The options given are surgical instruments, air ventilation system, healthcare personnel, and patient's clothing.

While surgical instruments and the air ventilation system have been noted as potential vectors for bacteria introduced via contamination, they are routinely sterilized and maintained to prevent such risks. Conversely, healthcare personnel move in and out of the sterile field and are engaged in the procedure. This activity can disperse bacteria into the air, particularly from their skin or attire. Moreover, a patient's clothing is generally not present within the sterile field of the OR.

Bacteria introduced via contaminated equipment, such as ventilators or intubation tubes, do play a role in infection, but these are not airborne sources. Airborne transmission commonly involves pathogens dispersed through activities like coughing or sneezing, which is less of a concern from properly sterilized instruments or well-maintained ventilation systems. The correct option in this context, focusing on airborne transmission as the mode of bacterial transfer, is C) Healthcare personnel. This aligns with the practices to reduce risk, such as the use of masks, gowns, and other protective gear designed to contain and minimize the spread of bacteria from individuals in the OR.
