Disposable gloves are one of the highest volume supplies for hospitals. With various departments, clinical tasks and all member of staff requiring different types and sizes of gloves, choosing the right one can be challenging.
Thanks to advancements in technology, exam and surgical gloves today have more features and benefits than ever before. Medline wants to make it easier for you to evaluate all the options on the market in order to select the right glove and material.
This guide breaks down the differences between major glove types in order to educate and help you make informed decisions.
A high percentage of healthcare professionals suffer from glove-related hand allergies. Clinical evidence shows that over 80 per cent of allergic contact dermatitis is attributed to a chemical allergy.1
A chemical allergy is a reaction to specific allergens such as chemical accelerators used in the glove manufacturing process of both latex and synthetic gloves.2 Using an accelerator-free glove can help prevent a user from suffering an outbreak.
Gloves with Accelerators Can Cause Chemical Allergies
Clinically speaking a chemical allergy will present itself as red, irritated, cracked and itchy skin on and around the area of contact.
The chemical allergy response begins when the antigens, such as residual chemical accelerators, leach from the glove and penetrate the skin, triggering the formation of T cells sensitised to the specific antigens.
Repeated exposure to the antigen in individuals who are allergic results in the reactivation of sensitised T cells and incites the inflammatory response causing the symptoms of red and itchy skin.2
How to Prevent Chemical Allergies
There are many ways to identify a chemical allergy, such as patch testing, diagnostic skin testing and blood or allergy testing. Once the chemical allergy is determined as the cause, the primary treatment is avoidance or minimisation of exposure to the allergen; however, there are also some medications and moisturisers that can help alleviate the symptoms.
DID YOU KNOW?

of 954 respondents at AORN congress indicated that staff continued to have allergy issues even when they switched to gloves without natural rubber latex.9
What Are the Different Types of Accelerators?
Accelerators are the chemicals used in the glove manufacturing process to help make gloves more durable and elastic. Some of the common chemical accelerators used are thiurams, dithiocarbamates, mercaptobenzothiazoles and diphenylguanidine.

Role in Glove Munufacturing
Thiurams
Account for 60% of accelerator-related skin irritation and are the primary cause of chemical allergy.3
The universal vulcanising agent for rubber is sulphur. Thiurams are ultra-fast accelerators and are the preferred primary accelerator for sulphur-cured rubbers with low unsaturation content. Thiurams are used as vulcanising agents in the absence of sulphur; the vulcanisates attain high degree of state of cure, exhibiting high tensile strength, lower elongation at break, higher rebound resilience and lower tear resistance.3 Because manufacturers can produce gloves containing thiurams in high quantities, the overall cost is low.
Dithiocarbamates / Carbamates
Account for 30% of accelerator-related skin irritation.3
Dithiocarbamate accelerators are widely used as ultra-fast accelerators for natural rubber latex-based compounds that absorb sulphur and facilitate cross-linking. They can also find applications as primary or secondary accelerators in most dry rubber-based sulphur-cured compounds.4
Mercaptobenzothiazoles (MBTs)
Account for between 1% and 5% of accelerator-related skin irritation.3
MBTs are a fast curing accelerator suitable for most common rubbers and contribute to tensile strength; the presence of stearic acid and zinc oxide is necessary for good cures. MBTs cause fewer cases of contact sensitivity.4
Diphenylguanidine (DPG)
Allergic reactions to this chemical are on the rise according to some recent reports.3
Diphenylguanidine is used as a secondary foam stabiliser in the silicofluoride foam process. It does not show better activity than thiuram and dithiocarbamates, but it does have better stability and also contributes to tensile strength. It is used as a complexing agent for the detection of metals and organic bases.5
Accelerator-Free Gloves
Accelerator-free gloves are a solution to the growing number of cases of type IV allergies.6 They will help reduce the number of professionals suffering from skin irritation not caused by latex. With a variety of options on the market, switching to accelerator-free gloves will allow individuals who have chemical allergies to continue working safely. It will also lessen treatment costs and limit the use of external staff when regular staff are unable to work.

Why Use Latex-Free Gloves?
There are multiple benefits to using latex-free gloves, for patients and staff as well as medical centres and the broader healthcare industry. Latex can cause varying degrees of allergic reactions, ranging from a stuffy nose and asthma attacks to anaphylaxis and very rarely, death.1 Some groups of society are especially susceptible, so it makes sense to use latex-free gloves across all health centres, thus eliminating the risk altogether.
Allergy Assessment
Whilst skin prick tests are available to assess sensitivity, these are costly and time-consuming.
Many patients and staff are unaware of their latex allergy, so this makes effective risk assessments difficult to perform.
With this in mind, healthcare professionals may choose to use latex-free gloves as a precautionary measure, particularly because it is fairly common for latex allergies to build up over time or develop suddenly and unexpectedly.1
Hospital Impact
Every time there is an incident involving latex gloves, it affects health, productivity and finances. Healthcare workers who have a latex allergy may have to deal regularly with dry, itchy and irritated skin; this could cause them to miss work because their hands are in such poor condition they cannot wear gloves.
When the regular staff is absent, temporary or external staff need to fill in. This could slow down hospital productivity and efficacy because they are not as familiar with the rounds, patients or policies.
From a financial point of view, the use of latex gloves could cost the hospital more money for treatments and creams for those effected by the allergy and increase the wage bills to external agencies.
Why Use Latex-Free Gloves
In 2003 a survey was conducted across the NHS in the UK and the outcome showed that 60 per cent of all sites had not made provisions to minimise or manage the risk of latex exposure.2 A lot can be done to improve these figures, and replacing latex with non-latex gloves is an easy and effective start. Once done, the advantages are quickly apparent.
By using only latex-free gloves, the cost of stock may decrease, as buying one product in bulk is cheaper than multiple products.
The number of incidents occurring in latex-free wards has decreased dramatically when a straightforward swap from latex to latex-free gloves was made.3 Reducing the number of incidents will directly correlate with a reduced amount of treatment costs for latex allergic reactions and decrease the costs for temporary or external staff.
Using latex-free gloves is clinically responsible, cost-effective and time-saving. Making the change to latex-free gloves allows patients to feel confident and secure in their treatment and contributes to a smoothly running medical centre. These are all priorities for healthcare professionals, so any opportunity to make a difference should be taken advantage of.
Why Use Powder-Free Surgical Gloves?
The use of powdered gloves remains prevalent in hospitals and surgeries, despite the wide range of risks and multiple international organisations advocating a switch to non-powdered stock. This means that preventable situations are occurring with both patients and staff.
Multiple studies have been conducted around the world and they have revealed a number of concerns. In some countries these studies have resulted in an outright ban of powdered gloves. There is wide-ranging literature supporting and explaining how changes can be made. The FDA (US Food and Drug Administration) has already banned the use of all powdered gloves.1 In the UK, there are government-led and health authority recommendations in place to discourage the use of powdered gloves.2
Staff Safety
The health of staff is directly connected to smoothly running hospitals. Infection control is understandably a key aspect of patient care, which should be prioritised, but perhaps other issues such as allergic reactions are not as widely understood.
Asthma and other breathing problems are connected to the use of powdered gloves because of the potential airborne nature of the powder. Conjunctivitis and joint inflammation are also most commonly connected to the use of powdered gloves.3
Dry skin, which can be exacerbated or turn into Irritant Contact Dermatitis (ICD),4 becomes difficult to manage and treat if powdered gloves continue to be used by healthcare professionals.
Prevention of Germ Transmission
Concerns around the use of powdered gloves are common in regard to wound closure too. The issue here is simply that any tape used to close a wound is more likely to stick to a powdered glove than a non-powdered one worn by the physician.
The powder that coats the gloves binds with sweat and any mucous and this contributes considerably to the risk of infection being spread across clinical spaces. As the powder comes into contact with equipment and fittings, infection or germs can begin to spread and are hard to isolate. More chemicals are contained in and are used for making powdered gloves. These chemicals can cause an allergic reaction and also make it harder for existing conditions to heal. This impacts the clinician’s ability to carry out frontline duties of care, which in turn may contribute to staff shortages and related cost issues, such as having to pay for external agency staff.
The smooth running of clinical spaces means meeting the needs of patients and staff in cost-effective and efficient ways. The challenge of providing a safe barrier against dirt and infection can be successfully overcome, as can ensuring that allergic reactions are kept to an absolute minimum, but investment and the openness for change are necessary. Non-powdered gloves are a sure way of impacting both of these challenges with instant and far-reaching results.5
Why Double Glove?
The risk of exposure to blood-borne pathogens is a major concern for surgeons and operating theatre staff. Although often undetectable to the human eye, microperforations in surgical gloves are large enough to allow pathogens to pass between the glove wearer and the patient and cause infection.
A recent study reported that over 80 per cent of all surgical glove perforations go unnoticed.¹ Another study reported that the incidence of glove microperforations increased with duration of wear.²
A proven method to reduce these risks is to double glove with a dark-coloured underglove.
Double Gloving Technique
While wearing a single glove protects the wearer from blood-borne infections, more protection is needed when needles and sharp instruments are involved, due to the high risk of punctures. Wearing two pairs of surgical gloves greatly minimises the risk of cross-contamination by adding an extra layer of protection.

Double Gloving Technique
If a perforation occurs, the inner glove is protected by the outer glove. A study by the American College of Surgeons showed double gloving reduces the risk of exposure to patient's blood by as much as 87 per cent when the outer glove is punctured.³
With the double gloving technique, the number of perforations in the inner glove can be reduced significantly, and the surgeon can identify holes faster when a darker underglove is used. According to a clinical study in the AORN Journal, when using on underglove with a contrasting colour, 84 per cent of perforations were recognised in an average of 22 seconds, whereas 8 per cent of perforations were identified in 47 seconds when using a single glove.4
How Does the System Work?
The wearer dons the specially designed darker-coloured underglove as the first layer of protection followed by a light-coloured or translucent overglove.
In the event that the outer glove is breached during surgery, blood and other fluids seep between the two glove layers, and the contrasting colour of the dark green underglove alerts the wearer to change gloves.
Changing gloves immediately following the breach minimises the risk of transmission of pathogens between the wearer and the patient.
While double gloving combinations are often a personal preference, it is highly recommended to use a different coloured underglove in order to spot the breach more quickly if the glove is punctured.
What About Surgical Technique?
Many surgeons are reluctant to use the double gloving technique because they feel it may reduce their tactile sensation and, consequently their dexterity can be impaired. However, a study conducted by the Royal College of Surgeons of England on double gloving and surgical technique shows that there is no significant difference in the surgical technique when using single gloves or double gloves.5 The results suggest that double gloving does not alter the surgeon's dexterity.
