RESUMO
Background: Along with several significant factors in chemotherapy treatment management’s nurses plays the pivotal role. The objective of this study was to evaluate the knowledge of nurses in relation to handling chemotherapy and the current practice of cancer centers in different hospitals in Bangladesh.Methods: The cross-sectional study was designed based on anonymous self-administered questionnaire. The questionnaire was developed from literature and expert input and validated by subject experts.Results: A total of 96 nurses were the respondents in this study. Around half of them already exposed directly with chemotherapy agents. Some 72.9% of nurses had not any training and 58.3% of respondents were not aware about use of closed system transfer devise in chemotherapy. A greater proportion 58.3% of nurses did not know the same health hazard of both oral and parenteral drugs. One third (33.3%) respondents used biological safety cabinet for doing preparation. Nurses’ did not use especial personal protective equipment and the designed treatment room also was absent. None of nurses went through regular medical checkup.Conclusions: The evidence-based results suggested that nurses have average knowledge about chemotherapy handling, however, use of personal protective equipment and biological safety cabinet, follow guidelines, medical surveillance and training are appeared to be a hindrance. More fundamentally, nurses need more education and professional training about chemotherapy agents handling in nursing school and through in-service continuing education as well as adopt required facilities are necessary.
RESUMO
Objective:There are many different kinds of biological safety cabinets, it make some difficulties in the allocation. Scientific selection which based experimental requirements choose the right equipment match experiments, it can effectively prevent the spread of pathogenic microorganisms of operation personnel damage and environmental pollution.Methods: According to its working characteristics, different laboratory levels, detection items and actual operation of dangerous levels of pathogenic microorganisms, to determine the matched biological safety cabinet.Results: According to the different experiments correctly, choose the appropriate biological safety cabinet, bio-safety has been obviously improved, the incidence of adverse events decreased from 12% to 3%; the experimenter's security has improved.Conclusion: Through the use of biological safety cabinet clear and selection method, can not only improve biological testing of safety consciousness, but also strengthen the biological safety standardization, institutionalization and standardization of the management mechanism, avoid the use of biological safety, improve the quality of the efficiency of laboratory work and experiment, laboratory personnel biological safety.
RESUMO
BACKGROUND: The purpose of this study was to compare the concentration of total airborne bacteria (TAB) in biosafety cabinets (BSCs) at universities and hospital microbial laboratories to assess the performance of BSCs. METHODS: TAB was determined by using the single-stage Anderson sampler (BioStage Viable Cascade Impactor). The samples were obtained three times (with the BSC turned off and the shield open; with the BSC turned off and the shield closed; and with the BSC tuned on and operating) from the areas in front of 11 BSCs. RESULTS: TAB concentrations of accredited and nonaccredited BSCs were determined. No significant differences were observed in the TAB concentrations of the accredited BSCs and the nonaccredited BSCs for the areas outside the BSCs in the laboratories (p > 0.05). TAB concentrations for the BSCs sampled with the shield open and the instrument turned off showed differences based on the sampling site outside the BSC in each laboratory. CONCLUSION: These results imply that TAB concentration is not altered by the performance of the BSCs or TAB itself and/or concentration of TAB outside the BSC is not a good index of BSC performance.

OBJETIVOS: Verificar evidências da formação de aerossóis durante a manipulação de cepas de micobactérias para teste de sensibilidade às drogas (ANT) e identificação (TIP) e o efeito da descontaminação com solução de álcool 70 por cento e luz ultravioleta (UV) na cabine de segurança biológica (CSB), após os procedimentos laboratoriais. MÉTODOS: Uma placa foi exposta na CSB durante os procedimentos de ANT e TIP. Ao término, a CSB foi limpa e descontaminada com álcool 70 por cento e exposta à luz UV por 15 minutos. Após esse tempo outra placa foi exposta por duas horas, somente com a ventilação da CSB ligada. As placas foram incubadas a 37ºC e observadas por 30 dias. Os esfregaços das colônias isoladas foram corados pelas técnicas de Ziehl Neelsen e Gram, e as colônias de bacilo álcool-ácido-resistente (BAAR) foram identificadas pelos métodos tradicionais. RESULTADOS: Nas 38 placas expostas durante o ANT, cresceram micobactérias em 10 placas (26,3 por cento), fungos em uma (2,6 por cento) e outros bacilos em duas (5,3 por cento). Das placas com micobactérias, oito (80 por cento) foram identificadas como M. tuberculosis e duas (20 por cento) tiveram identificação inconclusiva. Mesmo após a descontaminação com álcool 70 por cento e uso de UV, cresceram fungos em duas placas (5,3 por cento) e cocos em outras duas (5,3 por cento). Nas 30 placas colocadas nas CSB durante a TIP, cresceram micobactérias em 10 placas (33,3 por cento), fungos em duas (6,6 por cento), cocos em uma (3,4 por cento) e uma mistura de micobactérias e outro bacilo em uma (3,4 por cento). Não houve crescimento nas placas expostas após descontaminação das CSB com álcool a 70 por cento e uso de UV ao término da TIP. CONCLUSÃO: Durante os procedimentos houve formação de aerossóis contendo micobactérias, fato que ficou comprovado pelo crescimento de colônias de micobactérias nas placas expostas. Técnicas laboratoriais adequadas devem ser respeitadas para minimizar a formação de aerossóis...
OBJECTIVES: To verify the evidence of aerosol formation during the manipulation of mycobacteria strains for susceptibility (ST) and identification tests (IT) as well as the decontamination effect of alcohol solution 70 percent and ultraviolet (UV) radiation in biological safety cabinets (BSC) after laboratory procedures. METHODS: One plate was exposed in a BSC during ST and IT procedures. Afterwards, the BSC was cleaned and decontaminated with alcohol solution 70 percent and exposed to UV radiation for 15 minutes. After that, another plate was exposed for two hours, only with the BSC ventilation on. Both plates were incubated at 37ºC and observed for 30 days. The smears from the isolated colonies were stained with Ziehl Neelsen and Gram techniques, and acid fast bacilli (AFB) were identified by conventional methods. RESULTS: In 38 plates exposed during ST, there was mycobacteria growth in 10 plates (26.3 percent), fungi in one (2.6 percent) and bacilli in two (5.3 percent). Among those plates that presented mycobacteria growth, eight (80 percent) were identified as M. tuberculosis and two (20 percent) had inconclusive identification. Even after decontamination with alcohol solution 70 percent and UV radiation, two plates presented fungi growth (5.3 percent) and other two presented cocci growth (5.3 percent). Among 30 plates exposed during IT procedures, there was mycobacteria growth in 10 of them (33.3 percent), fungi in two (6.6 percent), cocci in one (3.4 percent) and one (3.4 percent) mixed mycobacteria and another bacillus. No growth was observed when alcohol solution 70 percent and UV radiation were used for decontamination after IT procedures. CONCLUSION: During the procedures there was aerosol formation with mycobacteria, which was proved by mycobacteria growth on the exposed plates. Not only should adequate laboratory techniques be respected to minimize aerosol formation, but professional expertise, the continuity of capacity...
