据近两年来我市城乡有些地方和有些外地调查资料表明,常有接种卡介苗不当形成局部脓肿病例,或接种成功率在60%左右,远远低于85%指标的要求。什么原因影响接种质量的提高呢?笔者经过近两年的实际操作观察认为,主要与操作方法、用药剂量和用针手法不对有关。根据卡介苗的特性和临床注射要求,要提高接种成功率应把好“四关”:一是责任关。就是要有高度的责任心,注射前要看清标签和有效期,皮内注射用的卡介苗绝不能注射到皮下或肌肉内。液体和冻干菌苗稀释后,用前一定要摇匀。另外卡介苗是活菌苗,活菌数会随着贮存时间的延长而下降,即使在有效期也是如此。因此,应及时使用效果较好。二是进针关。皮肤常规消毒,酒精干后,左
In recent two years, urban and rural areas in our city and some field survey data show that often inoculated BCG inappropriate formation of local abscess cases, or vaccination success rate of 60%, far below the 85% index requirements. What factors affect the quality of vaccination? The author after nearly two years of practical observation that the main method of operation, dosage and needle method is wrong. According to the characteristics of BCG and clinical injection requirements, to improve the success rate of vaccination should be a good “four off”: First, responsibility. Is to have a high sense of responsibility, to see labels and expiration before injection, intradermal injection of BCG must not be injected into the skin or muscle. Liquid and lyophilized bacteria diluted, be sure to shake well before use. In addition BCG is a live vaccine, the number of viable bacteria will decline as the storage time, even in the period of validity as well. Therefore, it should be timely and effective. Second, into the needle. Skin routine disinfection, alcohol dry, left
