A 5-year retrospective analysis of the management of 177 twin pregnancies was undertaken. Despite increased use of bed rest and ultrasonography as currently recommended, the perinatal mortality among twins (13.2%) remained almost 10 times that for singleton births. Although elective hospitalization for bed rest prolonged the pregnancy, it did not decrease the perinatal mortality. The authors believe this was attributable to bed rest being instituted too late, as 70% of perinatal mortality occurred before the 30th week of gestation, which was also the period of greatest neonatal morbidity. Suggested recommendations for improving management of twin pregnancies are discussed.
对177例双胎妊娠的管理进行了一项为期5年的回顾性分析。尽管目前建议增加卧床休息和超声检查的使用，但双胎围产期死亡率（13.2%）仍几乎是单胎分娩的10倍。尽管选择性住院卧床休息延长了孕周，但并未降低围产期死亡率。作者认为这是由于卧床休息开始得太晚，因为70%的围产期死亡发生在妊娠30周之前，而这也是新生儿发病率最高的时期。文中讨论了改善双胎妊娠管理的建议。
