C-部分早产增加的关键因素

根据九年的国家出生数据的分析，剖宫产部分占U.S.Singleton早产出生物的几乎所有增加。

Between 1996 and 2004 there was an increase of nearly 60,000 singleton preterm births and 92 percent of those infants were delivered by a cesarean section, (c-section), according to research by investigators from the March of Dimes and the U.S. Centers for Disease Control and Prevention (CDC) that will be published in the June issue of Clinics in Perinatology.

虽然在此期间，辛格尔顿早产的产量增加了约10％，但该组的C型率增加了36％。

早产是一个严肃且昂贵的健康问题，是生命的第一个月的主要死因。超过520,000名婴儿 - 每年八个中的一次 - 每年都在美国出生。

迟到的早产婴儿，那些出生于34-36周的妊娠，占美国单例的大部分增长率出生率。这些婴儿的呼吸问题具有更大的风险，喂养困难，温度不稳定（低温），黄疸，延迟大脑发育和死亡而不是处于期间出生的婴儿。这个新分析表明，这些晚期早产儿的C型递送量最大。

“While maternal and fetal complications during pregnancy may result in the need for a c-section, we’re concerned that some early c-section deliveries may be occurring for non-medically indicated reasons,” said Alan R. Fleischman, M.D., the March of Dimes medical director and senior vice president. “We need research to determine how many c-sections that result in preterm babies are not medically indicated and may place both mother and baby at risk for little or no medical benefit. ”

C部分是女性最常见的主要手术程序。More than 30 percent of the 4.1 million U.S. live births are delivered via c-section and the rate has increased dramatically since 1996. A c-section delivery can be lifesaving when there are complications during pregnancy, but it is a major operation with potential risks to the mother from the surgery and anesthesia and to the baby, if the delivery occurs too soon. The March of Dimes is concerned that some early deliveries may occur without good medical justification and may be done at the request of the mother or based on an inappropriate recommendation from the doctor.
