双胎妊娠中影响单卵双胎生长的急性羊水过多是少见的,其临床症状主要来自于其中一个羊膜囊的迅速扩张。早产是此症造成双胎妊娠围产死亡率(PMR)的主要因素。如果不予治疗,PMR可达100%。本研究的目的是要确定在瑞典双胎妊娠中急性羊水过多的发生率,并将有无经过羊膜腔穿刺放水治疗的结果作了比较。瑞典1980年1月1日至1987年12月31日期间15所医院共收治36名双胎妊娠合并急性羊水过多病例。诊断标准为入院前一周内耻骨联合至宫底高度(SF)突然增加超过3 cm。患者均经卧床休息及
Acute polyhydramnios, which affects the growth of monozygotic twins in twin pregnancies, is uncommon and the clinical symptoms are mainly due to the rapid expansion of one of the amniotic sacs. Preterm birth is the main cause of twin pregnancy perinatal mortality (PMR). PMR up to 100% if left untreated. The purpose of this study was to determine the incidence of acute polyhydramnios in twin pregnancies in Sweden and to compare the results with and without amniocentesis. Sweden from January 1, 1980 to December 31, 1987 15 hospitals treated a total of 36 pairs of twins with acute polyhydramnios cases of pregnancy. The diagnostic criteria for sudden increase in pubic symphysis to the fundus height (SF) within a week prior to admission increased more than 3 cm. Patients were bed rest and
