What are medical gloves?
Medical gloves are disposable gloves used during medical procedures
![Page 4: Know your medical gloves for better protection and patient ... · powdered gloves Warning: Powdered gloves may lead to foreign body reactions and the formation of granulomas in patients](https://reader035.vdocuments.net/reader035/viewer/2022071022/5fd73672adca300ee4045415/html5/thumbnails/4.jpg)
• Medical gloves are single-use items
• Decontamination and reprocessing for reuse should be avoided
![Page 5: Know your medical gloves for better protection and patient ... · powdered gloves Warning: Powdered gloves may lead to foreign body reactions and the formation of granulomas in patients](https://reader035.vdocuments.net/reader035/viewer/2022071022/5fd73672adca300ee4045415/html5/thumbnails/5.jpg)
Main typesof medical gloves
Surgical
Use for conducting surgical procedures
ExaminationUse in:
• Medical examinations
• Diagnostic & therapeutic procedures
• Handling of contaminated medical materials

How gloves prevent infection� Gloves prevent contamination of the hands of
healthcare personnel when touching blood, body fluids, secretions, mucous membranes, and non-intact skin� Gloves reduce the likelihood that microorganisms
present on the hands of healthcare personnel will be transmitted to patients
Failure to change gloves between patient contacts is an infection control hazard

Wearing gloves does not replace the need for hand rubbing and washing

FDA potential warning on powdered gloves
Warning: Powdered gloves may lead to foreign body reactions and the formation of granulomasin patients. In addition, the powder used on gloves may contribute to the development of irritant dermatitis and Type IV allergy, and on latex gloves may serve as a carrier for airborne natural latex leading to sensitization of glove users.

Detection of holesin gloves� Introduce 1000 cm3
water into the glove
� Observe for leaks immediately
� If the glove does not leak immediately, make a second observation after 2 to 4 minutes

Limited useof vinyl gloves
Vinyl gloves are appropriate only for short-term tasks that involve minimum stress on the gloves and low risk of exposure to blood and other infectious materials

Latex protein allergy
qNatural rubber latex (NRL) contains proteins
qSome of the proteins are allergens
qSensitization to NRL is caused by direct contact
qPrevalence of latex allergy in the general public is 1% and in healthcare workers from 0.6% to 10%

Practical considerations in glove use
Change glove if …
• The integrity of a glove is compromised and complemented with hand hygiene
Use double gloves if …
• There is a need to take precautions against HBV, HCV and HIV for long surgical procedures (>30 minutes)
• Performing procedures in contact with large amounts of blood and other body fluids
• Undertaking high risk orthopaedic procedures

Conclusion
� Gloves prevent contamination and the spread of infection by providing an effective barrier against microorganisms
� There are many different types of gloves and selecting the right ones for use will result in better infection control and protection of the healthcare personnel
