B-D胰岛素注射器重复使用的方法及安全性探讨

Study on the Safety of Reuse Disposable Insulin Syringe

塑料一次性胰岛素注射器重复使用的现象十分普遍。本文介绍重复使用B-D胰岛素注射器近千副的体会及注射器使用后的细菌观察结果。具体方法是每位患者不论每天注射几次,凡用满2d后均更换-副注射器。注射后用酒精棉签擦拭消毒针头.再重新套上针尖帽套。全部注射均由护士执行,并观察记录有无注射部位的红、肿、硬块形成及痛觉加重。接受治疗的55例糖尿病患者中,在 2 d内重复使用 4次者 24例,共 1960次;重复使用 6次者 25例,共 3100次;重复使用 8次者 6例,共 344次,均无1例出现过皮肤红肿、发痒及皮下硬结等。对其中8例重复使用各1～7d后的注射针头和针管作细菌培养,均无细菌生长。因此,作者认为2d内重复使用4～6次是十分安全的。

It is very common to reuse disposable plastic insulin syringes in clinical practice. Experiences in reuse of thousands of disposable insulin syringes and results of microbiological examination after reuse are reported. No matter how many injections were done daily, the syringe was replaced after two days. The needle of used syringe was sterilized with alcohol swab and covered with needle cap. All injections and observation of possible side effects were done by nurses. In 55 diabetic patients, syringes were reused for 4 times within 2 d in 24 diabetics, totally 1960 times; for 6 times in 25 cases, totally 3100 times of 344 times. No side effects such as red swollen, itch of skin and subcutaneous masses were found in all cases. In 8 cases, the syringes were reused for 1-7 d, and bacteriological cultural examinations were made on needles and syringes. No positive bacterium was found in all cultural dishes. It is concluded that it is quite safe to reuse disposable insulin syringes for 4-6 times within 2 d.
