To investigate the outcome of triplet pregnancy and the necessity and benefit of multifetal pregnancy reduction (MFPR).
Sixty cases of triplet pregnancy were collected. In 15 cases that did not choose MFPR, the triplets were spontaneously obtained. Out of the 45 cases with triplets obtained after infertility treatment, 32 chose reduction to obtain twins using transvaginal puncture of the fetal heart and physical hurt. The maternal obstetric complication rate, preterm delivery rate, means gestational age at delivery, birth weight of infants and percentage of fetal weights < 1,500 g were compared between these two groups.
The maternal obstetric complication rate and preterm delivery rate were lower significantly in the reduction group. Deliveries occurred earlier slightly in the triplets group compared with the reduction group. The mean birth weight of infants was higher and the percentage of low weight infants (< 1,500 g) was lower in the reduction group.
MFPR of triplets to twins is effective to improve pregnancy outcome. MFPR applied on triplets is reasonable and should be accepted if requested.
探讨三胎妊娠结局以及多胎妊娠减胎术（MFPR）的必要性和益处。
收集60例三胎妊娠病例。15例未选择MFPR的病例，三胞胎自然分娩。45例经不孕治疗后获得三胞胎的病例中，32例选择减胎术，通过经阴道穿刺胎儿心脏的方法减胎为双胎，造成了身体伤害。比较两组的孕产妇产科并发症发生率、早产率、平均分娩孕周、婴儿出生体重以及出生体重<1500g的胎儿比例。
减胎组的孕产妇产科并发症发生率和早产率显著更低。三胞胎组的分娩时间比减胎组稍早。减胎组婴儿的平均出生体重更高，低体重婴儿（<1500g）的比例更低。
三胎减为双胎的MFPR对改善妊娠结局有效。对三胎妊娠实施MFPR是合理的，如有需要应予以接受。
