How gloves prevent infections 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

What are medical gloves?

Used during medical examinations and procedures, and

surgery

Disposable

Powdered or powder-free

Made of polymer

Main typesof medical gloves

Surgical

Use for conducting surgical procedures.

Examination

Use in:Medical examinations

Diagnostic & therapeutic procedures

Handling of contaminated medical materials

Chemotherapy glovesFor safe handling of highly toxic cancer chemotherapeutic drugs

Thicker and longer than surgical or examination gloves

Tested for resistance to permeation of chemo drugs

Worn by:• Oncologists• Oncologic nurses• Hospital pharmacists• Pharmaceutical manufacturers

Gloves can be powdered or powder-free

Powdered gloves are coated with corn starch to make them easier to don

Powder-free gloves are chlorinated or have a synthetic coating for ease of donning

Barrier protection

The reason for wearing medical gloves is that they provide barrier protection against infectious agents

Natural Rubber Nitrile Vinyl

Rego A and Roley L, American Journal of Infection Control, Volume 27, Number 5, 1999.

Failure of vinyl gloves

after simulated use increased by

520%

Page 15: Know your gloves for better infection control · Selecting gloves. How gloves prevent infections ... Disposable. Powdered or powder-free Made of polymer Prevent contamination. Main

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

Page 16: Know your gloves for better infection control · Selecting gloves. How gloves prevent infections ... Disposable. Powdered or powder-free Made of polymer Prevent contamination. Main

Use of plasticizersin vinyl gloves

Vinyl or polyvinylchloride (PVC) is a hard plastic

It can be made softer and more flexible by the addition of plasticizers

The most common plasticizer used is di(2-ethylhexyl) phthalate, better known as DEHP

Vinyl gloves can contain up to 40% of DEHP

DEHP is not bound chemically to the PVC and can be leached out when in contact with blood or body fluids

Page 17: Know your gloves for better infection control · Selecting gloves. How gloves prevent infections ... Disposable. Powdered or powder-free Made of polymer Prevent contamination. Main

Sanctions against DEHP

US Department of Health and Human Services (DHHS) and Environmental Protection Agency (EPA) label DEHP as potential carcinogen and reproduction toxin

Many countries have banned DEHP in children’s toys

Japan and the European Union have banned DEHP in food service gloves

DEHP is banned in California’s Safe Drinking Water and Toxic Enactment Act of 1986

Latex protein allergy

Natural rubber latex (NRL) contains proteins

Some of the proteins are allergens

Sensitization to NRL is caused by direct contact

Prevalence of latex allergy in the general public is 1% and in healthcare workers from 0.6% to 10%

Page 19: Know your gloves for better infection control · Selecting gloves. How gloves prevent infections ... Disposable. Powdered or powder-free Made of polymer Prevent contamination. Main

Symptoms of latex protein allergy Local or systematic urticaria

Hay fever-like symptoms

Abdominal cramps

Difficulty in breathing

Rapid heart rate

Drop in blood pressure

Anaphylactic shock
