That's the conclusion of recent studies from South Asia.
The umbilical cord is usually cut right after birth.
The World Health Organization recommends leaving the stump alone.
But that raw stump can be a pathway for potentially fatal infection if the cord is cut with an unsterilized instrument, or if the baby is born in an unsanitary environment.
Newly-published research led by scientists at Johns Hopkins School of Public Health in Baltimore, involved about 30,000 newborn babies in Bangladesh. In 1/3, the umbilical cord's stump was left untreated. In the other births the stump was cleaned with an antiseptic called chlorhexidine, either one time or daily for a week after birth.
Professor Abdullah H. Baqui says the survival rate was significantly higher when the antiseptic was used. "What we found is, in the single cleansing there's a 20% lower neonatal mortality. In the seven-day cleansing, there's only 6% lower mortality, which is not statistically significant."只要用便宜的消毒剂进行简单的处理，就能每年挽救成千上万新生儿的生命。
这是最近从对南亚地区的研究中得出的结论。
婴儿出生后，脐带通常会被立即剪断。
世界卫生组织建议不用对伤口进行任何处理。
但是，如果脐带被未杀菌的器材剪断，或者婴儿出生的环境不卫生，那么脐带未经处理的残余部分则可能成为让病菌侵入的通道，从而有造成致命感染的潜在危险。
在最新发布的研究中，位于巴尔的摩的约翰霍普金斯大学公共卫生学院的科学家们对孟加拉的三万名新生儿进行了调查研究。其中，有三分之一的新生儿的脐带被剪断后没有做任何处理。其它的婴儿的脐带残余处都用一种被称为“洗必泰”的抗菌剂清洗，有的一星期只清洗一次，有的每天进行清洗。
阿布杜拉教授表示，当使用杀菌剂清洁后，新生儿的存活率明显提高。“我们发现，简单消毒可以降低20%的新生儿死亡率，运用七天消毒，却只有6%的下降，这倒是没有多大的统计学意义。”
