目的:本文旨在探索两种常用的灭菌方法(C060辐照灭菌和EO灭菌)对聚乳酸材料本身性能的影响。方法:采用测试和对比聚乳酸材料灭菌前后的抗压强度的方法评价不同灭菌方法对材料性能的影响。结果:C060灭菌后,聚乳酸材料发生脆性断裂,而EO灭菌对材料的抗压强度影响不显著。结论:C060辐射灭菌会对聚乳酸造成结构性的破坏从而影响其力学性能,EO灭菌则对此没有影响,但是聚乳酸材料对EO的吸附力较强,采用真空干燥法去除EO残留具有较好的效果。 相似文献

The paper deals with problems associated with reduction of undesirable effects of ethylene oxide in polymers in medical devices on the patient's health. The authors explain the need of careful elaboration and validation of the sterilization and aeration process incl assessment of ethylene oxide (EO) residues. The authors investigated the effect of the type of material and conditions of sterilization and aeration on the assessed EO concentration. For research of the behaviour of different polymers in the sterilization process model sterilizations of actual items of medical devices with a known composition proved more suitable than assessment in medical devices from medical institutions. The main conclusions of the investigation were a classification of polymers into those suitable and unsuitable for sterilization or resterilization, and attention was also drawn to poor reproducibility of results in old sterilizers, in particular those lacking effective aeration in aerators. 相似文献

Ethylene oxide (EO) is widely used in the health care industry as a gas sterilant for medical products that cannot withstand the high temperature and humidity associated with conventional steam sterilization. As a consequence, approximately 100,000 health care workers are exposed to residual EO each year. The acute toxicity of exposure to EO has been well documented, and recent concern about the mutagenic potential of occupational exposure to EO has resulted in an effort to further reduce workplace exposure levels to EO. The Environmental Protection Agency has issued a rebuttal presumption against registration of EO as a pesticide and the American Conference of Governmental Industrial Hygienists (ACGIH) has proposed a sharp reduction in the threshold limit value permitted for EO. Recognizing the need for environmental health personnel to become more familiar with this workplace hazard, it is appropriate to briefly review the toxic effects of acute and chronic exposure to EO residuals. The authors describe a gas sterilization system successfully utilized at the U.S. Public Health Service Hospital in New Orleans, La., which has demonstrated exposure concentrations well below the EO threshold limit value recently proposed by the ACGIH, while preserving the principal goal of assuring the sterility of reusable medical products which cannot be subjected to steam sterilization. 相似文献

Personal and environmental (stationary) ethylene oxide (EO) gas concentrations in gas sterilization facilities were measured at six workplaces in five hospitals. An ethylene oxide gas monitor (3M #3551) was used for both personal and stationary samplings. A gas detector tube was also used for instantaneous sampling. In most workplaces, the personal exposure levels of EO were below the detection limit of the gas monitor. Most of the time-weighted average (TWA) concentrations by the stationary sampling were below the threshold limit value of EO (TLV-TWA = 1 ppm), but in one workplace, more than 4 ppm of EO were detected in front of the sterilizer in a clean room during a 24-hour measurement, although all the personal exposure levels were below the detection limit. Method of aeration after the sterilization was very important for reducing the EO exposure. The EO gas concentrations in two workplaces where sufficient aeration was carried out were below the detection limit in all the stationary samples. In one workplace where insufficient aeration was performed, EO was detected from 16 of 17 stationary samples, and more than 90-200 ppm of EO was determined by the gas detector tube near the worker's face at the moment when the door of the sterilizer was opened and the sterilized materials were removed. 相似文献

The present study describes an investigation on the use and management of ethylene oxide (EO) which is used mainly as a sterilant in medical institutions in a Cabinet-order designated city. Information was obtained from a self-administered questionnaire on safety and health matters related to sterilization with EO gas. The questionnaire was sent to 189 medical institutions including major hospitals and randomly selected clinics. 127 questionnaire were returned and the analysis was carried out for 120 respondents, excluding seven respondents whose answers were found to be inappropriate. The proportion of medical institutions, employing more than 50 workers, in which an occupational health physician and/or health supervisor was appointed was 70% and was lower than for other industries. 1.6% of the employees engaged in EO sterilization activities in the hospitals, whereas in clinics the percentage was as high as 20%. Several problems were found both in the management and work methods with EO: operations were not isolated in 46%; gas leaks and back-streaming of exhaust gas were found in 59% and 41%, respectively; and personal protective clothing was not used in 69%. Improvement was found only for three items among the institutions where an occupational health physician was appointed. These results suggest that good workplace controls and practices are essential for medical institutions using hazardous materials including EO for sterilization. 相似文献
