Which method is NOT used to create a non-moric environment in an operating room?

1. Use of powdered gloves

2. Use of lint-free drapes

3. Rinsing instruments with saline

4. Use of milipore filters

The correct answer is: Use of powdered gloves

The choice of using powdered gloves is not a method employed to create a non-moric environment in an operating room. In fact, powdered gloves can introduce contaminants into the sterile field. The powder used on these gloves can carry particles that may lead to infections or complications during surgery, which goes against the principles of maintaining a sterile and non-moric environment. In contrast, utilizing lint-free drapes helps to prevent the introduction of fibers or lint that could carry microorganisms, thereby enhancing the sterility of the operating room. Rinsing instruments with saline is a method to ensure that any debris or contaminants are removed from surgical tools before they are sterilized and used, further supporting a non-moric environment. Milipore filters are used to ensure that liquids, such as solutions and subject materials, are sterilized by filtering out microorganisms, thereby contributing to the prevention of infections during surgical procedures.
