Abstract
We did retrospective assessment on the strategy of treatments for 19 mothers screened group B streptococcus［GBS］positive, antibiotics prophylaxis for 19 infants, the ratio of carrier of GBS in 19 infants, and the results of blood examination after birth from April 1, 2006 to January 31, 2008. We had 594 deliveries during this period. The strategy of treatment for mothers screened GBS positive was done according to the protocol of Centers for Disease Control and Prevention［CDC］. We made our original protocol of antibiotics prophylaxis for infants, considering of numbers of times of antibiotics prophylaxis for mothers, whether mothers had preterm rupture of membrane［PROM］or not. The mean number of times of antibiotics prophylaxis was 1.68（ 1～4 times）, 8 cases out of 19 mothers had PROM, the mean time from PROM to delivery was 13.1 hours （1～29 hours）, the mean gestational age was 39 weeks （37～41 weeks）, the mean birth weight was 2964g （2084～3284g）. We did antibiotics prophylaxis for 12 infants （63%）, 2 out of 12 were detected GBS colonization, none of them suffered from GBS infection. We did unnecessary antibiotics prophylaxis for 10 infants. So we realized that we should exchange information about mothers more closely with obstetricians and we should avoid unnecessary antibiotics prophylaxis for infants.
