目的：回顾日本妇女三胎妊娠的临床特征和短期结局。研究方法：对2005年1月至2008年12月期间在22孕周或以上分娩的320例三胎妊娠（8例单绒毛膜三胎，75例绒毛膜三胎和150例三绒毛膜三胎; 87例胎盘绒毛膜情况不明）的日本女性进行了回顾性分析。结果：剖宫产315例（98%）。分娩时的孕龄分别为32.3 ± 2.8周（平均值± SD）和33.2周（中位数），97%、61%和14%的妇女分别在小于37、小于34和小于30孕周分娩。对于活产婴儿，最重、中等和最轻三胞胎的平均出生体重分别为1762 +/- 437 g、1608 +/- 396 g和1406 +/- 380 g。18名（5.6%）妇女发生围产期死亡（1名妇女发生3例三胞胎，4名妇女发生2例三胞胎，13名妇女发生1例三胞胎）。围产期死亡率为每1000例分娩25例死亡，并随着绒毛膜数量的增加而下降（每1000例单胎、双胎和三胎分娩分别为125例、44例和20例）。结论：日本三胎妊娠的短期结局良好。这些数据可能对咨询三胞胎怀孕的日本妇女有用。(C)2012年国际妇产科联合会。由Elsevier爱尔兰有限公司出版。保留所有权利。
Objective: To review clinical features and short-term outcomes of triplet pregnancies among Japanese women. Methods: A retrospective analysis was carried out among 320 Japanese women with triplet pregnancies (8 monochorionic, 75 dichorionic, and 150 trichorionic triplets; 87 with unknown placental chorionicity) who delivered at 22 gestational weeks or more between January 2005 and December 2008. Results: Delivery was by cesarean for 315 (98%) women. Gestational age at delivery was 32.3 +/- 2.8 weeks (mean +/- SD) and 33.2 weeks (median), and 97%, 61%, and 14% of women delivered at less than 37, less than 34, and less than 30 gestational weeks, respectively. For live-born infants, mean birth weight was 1762 +/- 437 g, 1608 +/- 396 g, and 1406 +/- 380 g for the heaviest, middle, and lightest triplet, respectively. Eighteen (5.6%) women experienced perinatal mortality (3 triplets for 1 woman, 2, triplets for 4 women, and 1 triplet for 13 women). Perinatal mortality was 25 deaths per 1000 deliveries, and decreased with increasing number of chorionic membranes (125, 44, and 20 per 1000 mono-, di-, and trichorionic triplet deliveries, respectively). Conclusion: Short-term outcomes were good among triplet pregnancies in Japan. The data may be useful for counseling Japanese women with triplet pregnancies.
