The effects of the prolonged use (greater than seven days) of tocolytic agents, along with other established procedures of conservative, expectant management, were studied in 45 patients with either total or marginal-partial placenta previa. Our regimen prolonged pregnancy for seven days or more in 81.2% of total placenta previas and 91.7% of marginal-partial ones. Antepartum hospitalization and shortened neonatal length of stay resulted in a total saving of $18,175 per case. The prolonged use of tocolytic agents, in addition to expectant management, in patients with placenta previa increased the length of pregnancy, decreased neonatal morbidity and was cost effective.
对45例完全性或边缘部分性前置胎盘患者，研究了使用宫缩抑制剂（使用时间超过7天）以及其他已确立的保守性期待治疗程序的效果。我们的治疗方案使81.2%的完全性前置胎盘患者和91.7%的边缘部分性前置胎盘患者的妊娠延长了7天或更长时间。产前住院和新生儿住院时间缩短，每例患者总共节省了18,175美元。对于前置胎盘患者，除了期待治疗外，延长宫缩抑制剂的使用可增加妊娠时间，降低新生儿发病率，且具有成本效益。
