Abstract:

Background: Needlestick injuries are always associated with a risk of infection, because these types of punctures may expose healthcare workers to a patient’s blood and/or body fluids.

Objective: To compare the efficacy of 4 different types of surgical gloves for preventing exposure to blood as a result of needlestick injury.

Methods: For simulation of needlestick injury, a circular sample of pork skin was tightened onto a bracket, and a single finger from a medical glove was stretched over the sample. First, a powder-free surgical glove with a gel coating was used to test blood contact. Second, a glove with a patented puncture indication system was used to test blood contact with a double-gloved hand. Third, 2 powder-free latex medical gloves of the same size and hand were combined for double gloving, again to test blood contact. Finally, we tested a glove with an integrated disinfectant on the inside. The punctures were carried out using diverse sharp surgical devices that were contaminated with 99T marked blood. The amount of blood contact was determined from the transmitted radioactivity.

Results: For the powder-free surgical glove with a gel coating, a mean volume of 0.048 μL of blood (standard error of the mean [SEM], 0.077 μL) was transferred in punctures with an automated lancet at a depth of 2.4 mm through 1 layer of latex. For the glove with an integrated disinfectant on the inside, the mean volume of blood transferred was 0.030 μL (SEM, 0.0056 μL) with a single glove and was 0.024 μL (SEM, 0.003 μL) with 2 gloves. For the glove with the patented puncture indication system, a mean volume of 0.024 μL (SEM, 0.003 μL) of blood was transferred.

Conclusions: Double gloving or the use of a glove with disinfectant can result in a decrease in the volume of blood transferred. Therefore, the use of either of these gloving systems could help to minimize the risk of bloodborne infections for medical staff.
