Artigos esterilizados em calor úmido: validação do sistema de guarda

Abstract

We aimed at identifying the period of validity of the sterilization of items by humid heat, taking into account the conditions of sterilization and storage. The validation was carried out by means of microbiological tests performed with instruments in the same load and evaluated in 0, 7, 10, 15, and 25 days. 30% of the instruments in each package were analysed and put in a Mueller Hinton solution and incubated at 37 degrees C for 72 hours. The reading was accomplished taking into consideration how dark the solution was. Out of the samples evaluated in nine loads, none showed microbiological growth. It was concluded that, although sterilization and storage conditions of the material were not fully in accordance with parameters recommended by the literature, the sterilization happened and was maintained for a period of 25 days.

Reusing sterile cotton fabric barriers in the clinical practice: an observational and longitudinal study

“…Considering the findings of the studies that evaluated microbial growth in SVP-sterilized HPs ( 19 - 21 ) and the results of the DIN methodology test used in this study and in the aforementioned one ( 9 ) , it can be asserted that the fabric offers an effective microbiological barrier, although without consensus on the maximum frequency of washes to guarantee the barrier.…”

“…A survey ( 19 ) that evaluated SPV-sterilized HPs packed in cotton fabric concluded that, after 25 days of storage under controlled conditions, there was no microbial growth in the HPs. Another two studies ( 20 - 21 ) evidenced that the 100% double cotton fabric maintained sterility of the HPs for periods of 148 and 18 days, respectively.…”

Evaluation of Fabrics' Resistance for Surgical Aprons After Washing-Sterilization Process

“…It is worth noticing, though, that most studies use different sterilization methods according to internal norms of each institution (hospital laundry or industrial laundry services), lacking a standardization. For example, in hospital A, each sterilization cycle lasts for 17 minutes using temperatures ranging from 121ºC to 131ºC, hospital B uses temperatures of 121ºC to 123ºC for 30 minutes, in a third hospital C they used a sterilization process of 134ºC for 45 minutes, while a fourth institution utilized 134ºC for 12 minutes (Burgatti, J. C., Possari, J. F., Moderno, 2004;Neves et al, 2004;E. Rodrigues et al, 2006).…”

Causas de retrabalho de produtos para Saúde no centro de materiais e esterilização

“…Autores consideram que caixas cirúrgicas mantiveram-se estéreis mesmo após contaminação proposital por microrganismos e armazenamento inadequado 10 . No entanto, pesquisadores afirmam que esse prazo deve ser estabelecido, levando-se em conta vários fatores, como limpeza, invólucro e armazenamento, que possam garantir a manutenção da esterilidade 11,12 .…”
