目的了解卡介苗(Bacillus Calmette Guerin,BCG)预防接种质量,分析存在问题及其影响因素,提出改进措施,促进预防接种规范、安全、有效地开展。方法用卡介菌纯蛋白衍生物(Purified Protein Derivative of BCG,BCG-PPD)试验方法,随机调查248名儿童接种BCG3个月后的阳转率。结果BCG-PPD试验总阳性率为78.23%;城市儿童BCG-PPD试验阳性率高于农村儿童。卡痕大小与BCG-PPD试验阳性率呈正相关;医院产科接种BCG的儿童,BCG-PPD试验阳性率高于在预防接种门诊接种BCG的儿童。结论加强对BCG接种人员,尤其是农村预防接种门诊人员的技术培训,提高接种质量。严格实行在医院产科为新生儿接种BCG,有利于提高及时接种率和接种质量。
Objective To understand the quality of vaccination against Bacillus Calmette Guerin (BCG), analyze the existing problems and their influencing factors, propose improvement measures and promote vaccination norms, and carry out them safely and effectively. Methods The positive rate of BCG in 248 children after 3 months of BCG inoculation was investigated by the method of Purified Protein Derivative of BCG (BCG-PPD). Results The total positive rate of BCG-PPD was 78.23%. The positive rate of BCG-PPD in urban children was higher than that of rural children. The size of the mark was positively correlated with the positive rate of BCG-PPD test. The positive rate of BCG-PPD test in children hospitalized with obstetrical BCG was higher than that of BCG vaccinated clinic. Conclusion The technical training of BCG inoculation personnel, especially rural vaccination clinic staff should be strengthened to improve vaccination quality. Strict implementation of obstetrics and gynecology at the hospital for neonatal inoculation of BCG, help to improve timely vaccination rates and vaccination quality.
