1987～1990年,对我市卫生院用75％酒精浸泡消毒塑料头皮针与压力蒸汽灭菌硅胶管头皮针的消毒效果进行了监测。对75％酒精浸泡的148份头皮针,用RPHA法检查了乙型肝炎表面抗原,结果阳性样品19份(12.8％);对压力蒸汽灭菌硅胶管头皮针,检查134份,阳性2份(1.5％)。两组经统计处理,x~2=21.3,P<0.01,有非常显著性差异。对细菌污染的检测;75％酒精浸泡的头皮 From 1987 to 1990, the disinfection effect of 75% alcohol-impregnated plastic scalp needles and pressure-steam-sterilized silicone scalp needles was monitored in our hospital. Of 148 scalp needles soaked in 75% alcohol, HBsAg was examined by RPHA method, and 19 samples (12.8%) were positive samples. For pressure-steam sterilized silicone scalp needles, 134 samples were positive and 2 samples were positive 1.5%). Two groups by statistical processing, x ~ 2 = 21.3, P <0.01, there is a very significant difference. Detection of bacterial contamination; 75% alcohol-soaked scalp
