1950年9月,一位足月经产妇因急性右下腹痛到德克萨斯大学(Universityof Texas)的帕克兰德医院(Parklandhospital)急诊室就诊。当平躺在检查床上时,孕妇出现面色苍白、浑身虚汗、血压测量不到、心率160次/每分钟。医生怀疑子宫破裂,急诊开腹探查,子宫、胎儿均正常。什么原因引起这个孕妇术前的休克症状呢?几天以后,又一个孕妇急诊入院,平躺时出现休克症状,血压65/40mmHg。但是,这个孕妇自己换成侧卧位,休克症状消失,血压回升到132/80mmHg。当医生要求这个孕妇再一次平躺几分钟后,她的血压又降到60/35mmHg。当然,孕妇拒绝继续平躺。这是产科医生霍华德(Howard Ben K)等人1953年发表的论文开头的两个病例(1)。
