新鲜蒸馏水和储留蒸馏水冲洗清除热原效果比较

目的了解新鲜蒸馏水和储留蒸馏水冲洗去热原的效果。方法用鲎试验方法对三效热原灭活剂浸泡去热原洗涤的玻璃注射器进行了检测。结果经用新鲜过滤流动蒸馏水清洗的注射器,热原检测合格率为98.3%。用储存24 h的蒸馏水清洗后的注射器热原检测合格率65.0%;储存48h的蒸馏水清洗后的注射器热原检测合格率为45.0%。结论经去热原处理后的玻璃器材应该用新鲜流动蒸馏水进行清洗,储存24 h以上的蒸馏水清洗会影响最终去热原效果。

COMPARATIVE EFFICACY OF RINSE WITH FRESH DISTILLED WATER VS. STORED DISTILLED WATER IN ELIMINATING PYROGEN

Objective To know the efficacy of rinse with fresh distilled water and stored distilled water in eliminating pyrogen.Methods Limulus amebocyte lysate test was used to examine the glass syringe which had been immersed in triple-effect pyrogen inactivator for washing off pyrogen.Results The pyrogen examination eligible rate of the syringe washed with fresh filtrated flowing distilled water was 98.3%,while that of the syringe washed with the distilled water which had been stored for 24 h was 65.0% and that of the syringe washed with the distilled water which had been stored for 48 h was 45.0%.Conclusion The glass appliances after treated for eliminating pyrogen should be washed with fresh flowing distilled water,while washing with distilled water which had been stored for longer than 24 h would influence the final efficacy in eliminating pyrogen.
