The purpose of this study was to examine and to determine whether triplet pregnancies are associated with a significantly greater risk of adverse outcome than are twin pregnancies.
Maternal and perinatal outcomes were evaluated retrospectively in 41 sets of triplets and twin pregnancies that were matched for maternal age, parity, mode of delivery, preterm delivery, mode of conception, and antepartum complications.
Perinatal outcome in triplet versus twin gestation.
Triplets had a significantly lower mean average birth weight than in twin gestation (1,596 vs. 2,317 g, p<0.018) and gestational age at delivery (32.9 vs. 35.9 weeks; p< 0.03). Preterm labour occurred significantly more often in triplet than in twin gestation (80.5 vs. 41.5%) as did preterm delivery (87.8 vs. 46.2%). Triplets required a longer hospital stay than did twins (25 vs. 9 days; p<0.04). There were no significant differences between the groups in number of administrations to the Special Care Baby Unit (32.5 vs. 30.5%). Apgar score <7 at 5 min was significantly more in triplet as compared with twin gestation (17 vs. 6%; p<0.0015). Neonatal deaths occurred significantly more in triplets than in twins (26 vs. 8.5%; p< 0.0001). There were no significant differences between the groups in maternal antepartum or neonatal complications such as anaemia, pregnancy-induced hypertension, placental abruption, respiratory distress syndrome or intraventricular haemorrhage. Preterm labour was the only complication that occurred significantly more often in the triplet than in the twin gestation.
We concluded that this information could be useful in counseling patients with respect to the anticipated perinatal outcome of triplet pregnancies.
本研究旨在检验并确定三胎妊娠与双胎妊娠相比，不良结局风险是否显著更高。
回顾性评估41组三胎和双胎妊娠的孕产妇及围产期结局，这些妊娠在产妇年龄、产次、分娩方式、早产、受孕方式和产前并发症方面进行了匹配。
三胎妊娠与双胎妊娠的围产期结局。
三胎妊娠的平均出生体重显著低于双胎妊娠（1596克对2317克，p<0.018），分娩时的孕周也显著低于双胎妊娠（32.9周对35.9周；p<0.03）。三胎妊娠中早产的发生率显著高于双胎妊娠（80.5%对41.5%），早产分娩的发生率也是如此（87.8%对46.2%）。三胎妊娠比双胎妊娠需要更长的住院时间（25天对9天；p<0.04）。两组在特殊护理婴儿病房的护理次数上没有显著差异（32.5%对30.5%）。与双胎妊娠相比，三胎妊娠5分钟时Apgar评分<7的情况显著更多（17%对6%；p<0.0015）。三胎妊娠的新生儿死亡显著多于双胎妊娠（26%对8.5%；p<0.0001）。两组在产妇产前或新生儿并发症如贫血、妊娠高血压、胎盘早剥、呼吸窘迫综合征或脑室内出血方面没有显著差异。早产是三胎妊娠中比双胎妊娠显著更常发生的唯一并发症。
我们得出结论，这些信息对于为三胎妊娠患者提供围产期预期结局的咨询可能有用。
