During the past four years, an attempt has been made in Malmö to reduce the frequency of preterm termination of twin pregnancies. For this purpose, the entire pregnant population of this medium-sized city was subjected to general ultrasonic screening in the second trimester. This detected 88 per cent of the twin pregnancies. The screening has a methodological error of 2 per cent. Eightysix of the women with twin pregnancy were subjected to bedrest in hospital for more than two weeks in the second half of gestation. The incidences of twins born with birth weight below 1 500 g and of twins light-for-gestational-age were reduced compared with those a decade earlier. Also the group of twins born before the 37th week decreased, and the perinatal mortality rate fell to the same level as in singleton pregnancies. Early detection of twin pregnancies followed by rest for the pregnant women seems to contribute to an improved outcome of these gestations.
在过去四年里，马尔默一直在尝试降低双胎妊娠早产的发生率。为此，这座中等规模城市的所有孕妇在孕中期都接受了常规超声筛查。这检测出了88%的双胎妊娠。该筛查的方法误差为2%。86名怀有双胎的女性在妊娠后半期住院卧床休息了两周多。与十年前相比，出生体重低于1500克的双胎以及小于胎龄双胎的发生率有所降低。37周前出生的双胎组也减少了，围产儿死亡率降至与单胎妊娠相同的水平。早期检测双胎妊娠并让孕妇休息似乎有助于改善这些妊娠的结局。
