One hundred eighty-nine twin pregnancies were delivered at Wilford Hall United States Air Force Medical Center from July 1977 through December 1985. Among these, 57 were referred from distant bases and were excluded from further analysis. The remaining 132 pregnancies from our local population make up the study group. Sixty-seven women (51%) followed our advice to be hospitalized at or before 28 weeks' gestation for prophylactic ward rest. The remaining 65 women (49%) were not hospitalized until after 28 weeks' gestational age or until a pregnancy complication or labor occurred. Only three of 134 infants (2%) whose mothers were admitted died, versus 11 of 130 infants (8.5%) whose mothers were not admitted (P less than .03). The results suggest that prophylactic ward rest, implemented at or before 28 weeks' gestational age, may reduce perinatal mortality in this condition.
1977年7月至1985年12月期间，189例双胎妊娠在美国威尔福德霍尔空军医疗中心分娩。其中，57例是从偏远基地转诊而来，被排除在进一步分析之外。其余来自本地人群的132例妊娠构成了研究组。67名女性（51%）听从我们的建议，在妊娠28周及以前住院接受预防性病房休息。其余65名女性（49%）直到孕28周后或出现妊娠并发症或临产才住院。母亲入院的134例婴儿中只有3例（2%）死亡，而母亲未入院的130例婴儿中有11例（8.5%）死亡（P<0.03）。结果表明，在妊娠28周及以前实施预防性病房休息，可能会降低这种情况下的围产期死亡率。
