配药注射器有效使用时间的研究

Effective Storage Life of Unsealed Syringes Used for Dispensing Solutions

目的 确定注射器启封后的有效使用时间。方法 对 12个科室的 12 0具注射器在启封后配制非抗生素药液与抗生素药液过程中每隔 1h采样培养做微生物学鉴定。结果 启封后配制非抗生素药液 ,4h内无细菌生长 ,7h内样本合格率达 88 81% ;配制抗生素药液 ,5h内无细菌生长 ,7h内样本合格率达 93 33%。结论 配药注射器使用有效时间定为 4h。

OBJECTIVE To determine the storage life and applicability of unsealed syringes. METHODS A hundred and twenty syringes used in 12 clinical departments of this hospital were divided into two groups: one for dispensing antibiotic solutions and the other for non-antibiotic solutions.Samples from the unsealed syringes were collected,cultured and evaluated every one hour for identification of bacteria. RESULTS Negative bacterial cultures were obtained during the initial 4 and 5 hours in the groups of dispensing non-antibiotic and antibiotic solutions. The total eligibility rates were 82.67%and 96.43%, respectively for the groups of dispensing non-antibiotic and antibiotic solutions, 7 hours after unsealing. CONCLUSIONS Syringes should be used within 4 hours after unsealing.
