Validation of instrument reprocessing methods for the Ipas manual vacuum aspiration devices

To validate recommended reprocessing methods for Ipas manual vacuum aspiration (MVA) devices.

All recommended reprocessing methods for Ipas MVA devices were tested for effectiveness in cleaning, achieving high-level disinfection (HLD) and/or sterilization, and any physical effects on instruments. Worst-case scenario testing was performed using artificial soil and microorganisms. Study protocols replicated standard steps for reprocessing. The specified method for reprocessing was performed 25 times on multiple devices, including controls. After runs 1, 2, 3, 15, and 25, devices and controls were analyzed for: microbial growth; residual soils; surface damage; and functionality.

All samples were negative for microbial growth and residual soils. On inspection and functionality testing, no damage was observed for aspirators and cannulae except with STERRAD and Cidex OPA. Other methods of HLD and sterilization did not affect surfaces or functionality through 25 cycles.

Ipas MVA devices were not negatively affected following validated instrument reprocessing methods for HLD or sterilization for up to 25 reuse cycles. STERRAD and Cidex OPA did not meet assessed standards and are therefore not recommended. Strict adherence to guidance is critical for effective reprocessing of instruments.
