Análise da eficiência da limpeza do centro cirúrgico do hospital regional Dr Hamilton Cidade (Manicoré, Amazonas, Brasil)

Abstract

Despite the progress made in controlling Hospital Infection (IH), it remains a major challenge for surgery, as it is an issue that is important for decision-making, however, to minimize and control its incidence, it is necessary to apply preventive, educational measures and control. Staphylococcus aureus, Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa are cited among the microorganisms that cause IH, as well as related to antimicrobial resistance. Occasionally cases of IH are reported at the Dr. Hamilton City Regional Hospital in the municipality of Manicoré, State of Amazonas. These cases are treated directly in the medical unit itself, but the cause of these infections is not investigated, making it impossible to develop prophylactic measures to minimize and / or eradicate them. Therefore, the objective of this study is to analyze the efficiency of cleaning of the operating room (CC) of this hospital. For this, seven samples were taken from the surfaces of CC materials, furniture and structures after concurrent cleaning. The samples were transported to the General Biodiversity Laboratory of the Leônidas and Maria Deane Institute - Oswaldo Cruz Foundation, where Pseudomonas isolated colonies were obtained by classical microbiological methodologies, as well as the resistance profile of P. aeruginosa against five antimicrobials. (CPM / 30μg, CAZ / 30μg, CIP 5μg, GEN / 10μg and MER 10μg) by disc diffusion technique. Of the seven samples collected on the surfaces of CC furniture and structures, about 86% showed Pseudomonas contamination, where six points showed growth. Moreover, the results show that 40% of the strains have resistance to CPM / 30μg and 60% of the strains have resistance to CAZ / 30μg, indicating that in the treatment of IH, these antibiotics are not effective. The results of this research were presented to the management and staff of the hospital's CC. A lecture on health education was also offered to the students of a 2nd year high school class at the State School of Full Time Historian Arindal Vinicius da Fonseca. It can be concluded that patients at the CC of Dr. Hamilton City Regional Hospital are susceptible to IH due to the ineffectiveness of concurrent cleaning. Thus, better cleaning conditions should be employed and further studies should be conducted to analyze its effectiveness and prevent the occurrence of HI as well as the indiscriminate use of antibiotics.
