淮阴市级医院产科卡介苗接种质量分析

Quality analysis of BCG vaccination in city hospitals

1995年6月～1997年3月三所医院接生活婴3760名,接种卡介苗3647名,接种率97%;12周后268名婴儿接种 BCG-PPD,复验241名,复验率89.9%,阳性208名,阳性率86.3%,PPD 反应均径6.33mm,标准差2.39mm;卡痕均径≥3mm 者216名,占89.6%;<3mm 者占10.2%,无卡痕者占0.8%,卡痕均径3.85mm,标准差1.16mm。卡痕均径<3mm 25名 PPD 阳性16名,阳性率64.0%;≥3mm、<6mm194名,阳性率87.8%;卡痕>6mm20名,阳性率100%,卡痕大小与 PPD 反应强度,直线相关分析 r=0.469,t=5.959,P=0.000,呈正相关;直线回归方程 Y=2.781+0.943X。

In 1995.6—1997.3,3 760 babies are born in three hospitals,3647 are vaccinated with BCG,vaccination rates is 97%.After 12 weeks,268 babies vaccinated with BCG-PPD and 241 cases checked in 72 hours,reexamine rates is 89.9%.The positive among them are 208 cases,positive rates is 86.3%. The reaction induration average diameter of PPD are 6.3mm,standard deviation is 2.19mm;The scar aver- age diameter≥3mm are 216 cases(89.6%),<3mm is 10.2%,no scar is 0.8%.The scar average diameter is 3.85mm,standard deviation is 1.16mm.Among 25 cases of the sear average diametr less than 3mm,16 cases are positive of PPD reaction,the positive rates is 64.0%.Among 196 cases that the scar average diame- ter between 3mm and 6mm,the positive rates is 87.8%,and scar≥6mm in 20 cases,the positive rates is 100%.The analysis of straight line relation r=0.469,t=5.959,P=0.000.It's positive relation between the scar size and PPD reaction.The straight line regression eguation Y=2.781+0.943X.
