TI  - Effects of different disinfection and sterilization methods on tensile strength 
      of materials used for single-use devices.

AB  - Driven by economic and time constraints, some medical centers and third parties 
      are resterilizing single-use devices (SUDs) for reuse. The steam autoclave is 
      quick, but most plastics used in SUDs cannot survive the temperature. Thus, a 
      number of new methods of cleaning, disinfecting, and sterilizing these complex 
      devices are being introduced on the market. The present study investigated the 
      effects of a range of methods on the tensile strength of latex rubber, silicone 
      elastomer, 2 different formulations of polyurethane, nylon, and high-density 
      polyethylene (HDPE) specimens. The methods used were sodium hypochlorite bleach 
      (Clorox), peracetic acid + hydrogen peroxide (Steris), formaldehyde gas 
      (Chemiclave), low-temperature peracetic acid and gas plasma (Plazlyte), and 
      low-temperature hydrogen peroxide gas plasma (Sterrad). The results showed that 
      silicone elastomer was minimally affected, whereas the strengths of nylon, 
      polyethylene, and latex were reduced by some of the methods. Depending on the 
      formulation, the strength of polyurethane either increased or decreased. The data 
      demonstrated that disinfection and sterilization can affect the tensile strength 
      of certain materials used in medical devices.
