The feasibility of prolonging the delivery interval of the fetus or fetuses in multiple gestations after the preterm delivery of one fetus has been demonstrated. Five clinical reports and a literature review served as the database for this study. Pregnancy was extended in each of five patients with multiple gestations after the extreme preterm delivery of one fetus. Four of the six remaining infants survived. The literature reviewed shows successful survival in 42 of 52 (81%) such asynchronously delivered infants. Use of tocolytic therapy, broad-spectrum antibiotics and cerclage allows pregnancy extension when delivery occurs asynchronously in multiple gestations. The patient's strong desire and full understanding of the potential risks are mandatory before such an endeavor is attempted.
在一个胎儿早产之后延长多胎妊娠中一个或多个胎儿分娩间隔的可行性已得到证实。五篇临床报告及一篇文献综述作为本研究的数据库。五例多胎妊娠患者在一个胎儿极早产之后，妊娠得以延长。其余六个婴儿中有四个存活。所综述的文献显示，在52例此类不同步分娩的婴儿中有42例（81%）存活成功。当多胎妊娠不同步分娩时，使用宫缩抑制剂、广谱抗生素及宫颈环扎术可延长妊娠。在尝试这种做法之前，患者的强烈意愿及对潜在风险的充分理解是必不可少的。
