The sterilization efficacy of reprocessed single use diathermy pencils

Abstract

In Brazil, single use diathermy pencils (SUDP) are among the most common reused devices.This study assesses the sterilization efficacy of reprocessing SUDP using two cleansing methods (manual or automated), followed by one of three of the low-temperature sterilization methods: Hydrogen Peroxide Plasma (HPP), Ethylene Oxide (ETO) or Low-Temperature Steam Formaldehyde (LTSF). The sample was composed of 360 SUDP after their first use.The probability of sterilization failure was estimated considering the number of positive microbiological results obtained by cultures of the studied devices. The overall sterilization failure probability for SUDP was 0.26. The sterilization method, which presented the lowest failure probability was the LTSF (0.01), followed by ETO (0.21) and HPP (0.56). Automated cleansing obtained a better result than manual cleansing. This trial demonstrated that the probability of sterilization in reprocessed SUDP is highly dependent on both the type of cleansing and the sterilization method applied.

Evaluation of efficacy of repeated decontamination and sterilization of single‐incision laparoscopic surgery ports intended for 1‐time use

“…The material composition of single‐use devices (SUD) makes effective decontamination and sterilization difficult to achieve. SUDs have demonstrated mechanical malfunction and bacterial colonization when reused .

“…SUDs have demonstrated mechanical malfunction and bacterial colonization when reused. [5][6][7][8][9][10] The US Food and Drug Administration (FDA) issued a review and recommendations for reuse of single-use instruments. 7 The FDA stated that although data was insufficient to reach a conclusion, using reprocessed devices does not appear to pose elevated health risks.…”

Recent advances in low temperature sterilization - Moving ahead from Cidex™/ETO to OPA/Ozone: An update

“…Low temperature sterilization (LTS) has invaded the operation theatre (OT) because many components of advanced minimally invasive surgical (MIS) instruments, including robotic surgery equipment, have zero tolerance for high temperature steam sterilizers. Modern low-temperature sterilization processes[ 1 2 3 4 5 6 7 ] include ethylene oxide (ETO), hydrogen peroxide plasma, low-temperature steam and formaldehyde (LTSF), gamma radiation, electron beam technology and liquid chemical sterilizing (LCS), with the latest addition being ozone (O 3 ).…”

“…However it requires prolonged aeration times besides being mutagenic, carcinogenic, irritant to the eye, skin and airway, and can cause neurological, liver and kidney damage. [ 1 2 ] Gas plasma sterilization is safe, quick and requires no aeration. Vaccum, injection, diffusion, plasma and vent are the five steps followed by the Sterrad™ gas plasma system that are completed within 30 minutes.…”
