Choosing
the Right Glove: Latex, Vinyl or Nitrile?
A HIDA HAND HEALTH TOOL
HIV. Hepatitis C. Anthrax. The best way to avoid contact with microorganisms
and to avoid widespread contamination among clinicians and patients
is to put a barrier between hosts. This means selecting a glove that
will provide the tactile sensitivity and strength needed to perform
the task at hand while controlling glove associated reactions and exposure
to infectious substances. To accomplish this, clinicians need to evaluate
the performance and durability of a glove’s base material and
consider these factors in conjunction with the level of patient contact,
the procedure being performed, and the exposure and infection risks
associated with providing care.
BASE MATERIAL:
Gloves can be manufactured from latex, vinyl, nitrile, polyurethane,
neoprene, and a host of other materials. Each barrier has its strengths
and weaknesses. Latex is flexible, strong, and long lasting, but latex
allergies can produce severe reactions. Vinyl gloves
can be an alternative to latex, but the barrier can crack, break, or
separate when stressed by instruments, fingernails, or stretching. Nitrile
is resistant to many chemicals and resistant to punctures and abrasion
but tends to be stiffer than latex. Other glove materials can be degraded
when exposed to certain chemicals commonly used in patient care setting
or when improperly stored.
COMMON PRACTICES:
Glove performance can only be as good as the practices that maintain
their integrity. Certain oils, such as Vaseline, can break down latex
and should be washed away before glove donning. Fingernails and jewelry
can tear or compromise virtually any glove’s performance. Gloves
not properly changed between tasks and procedures can spread infectious
agents. Glove material can be fatigued by rigorous manipulation. Clinicians
must consider activities and practices when selecting their gloves.
POWDER:
Glove powder can absorb latex proteins and other chemicals. As a result,
glove powder can become aerosolized during donning and glove removal
and provide a vehicle for spreading latex proteins and other substances.
Powder can also carry microorganisms, which could contribute to disease.
Powder in a wound or surgical site can reduce the effectiveness of the
patient’s local immune system making him more vulnerable to infections.
Strong consideration should be given to restricting the use of powdered
gloves in contagious infection wards, in immune-comprised isolation
setting, in neonatal units, and in surgical environments. The National
Institute of Occupational Safety and Health (NIOSH) recommends that
latex gloves be powder-free, with reduced protein
content.
PERFORMANCE
It is essential that gloves have the barrier durability needed to perform
the task at hand. Glove durability needs to be considered when contact
with infectious materials is expected.
