旧金山加利福利亚大学一项研究表明:用β-肾上腺素能药阻止早产,平均每分娩一次能节约母婴医疗费10,000美元以上。研究者发现,在妊娠的第34周之前用子宫松弛剂以延长妊娠时间,节约的新生儿护理费用远远超过孕妇接受药物治疗所花的费用。在妊娠的第26—33周开始用抑制药防止早产,可使每分娩一次节约开支11,240美元。如果在妊娠的第20-25周开始治疗,每个幸存的婴儿节约的开支甚至高达39,000美元。近年来,已广泛应用β-贤上腺素能药阻止早
A study at the University of California, San Francisco, showed that the use of beta-adrenergic drugs to prevent premature birth, the average cost per childbirth can save more than 10,000 US dollars of maternal and child medical expenses. The researchers found that using uterine relaxants to extend pregnancy time before the 34th week of pregnancy saves the cost of neonatal care much more than the cost of a pregnant woman receiving medication. Preventing preterm birth with inhibitors from the 26th to the 33rd week of pregnancy saves $11,240 per point of delivery. If treatment is started between the 20th and 25th week of pregnancy, each surviving infant saves even as much as $39,000. In recent years, β-adrenergic drugs have been widely used to prevent early
