分娩过程中产妇是否应限于一种体位或限制产妇活动早有争议。十九世纪末及二十世纪初,部分学者认为:产妇限制于一种体位是一种过头的措施,它使产程延长、产妇疲劳、先露异常及产妇痛苦不安。随着围产医学的发展,产妇、胎儿及婴儿的安危日益受到重视,产科工作中是否存在过多的人为干预仍是目前所关注的问题。产妇体位便是其一。在分娩过程中除产力、产道及胎儿三因素外,为更全面地了解分娩过程,还应考虑产妇体位(maternal posture或positioning)。在决定产妇能否自然分娩时与其他三因素同样重要。产妇体位能改变宫缩、胎儿及骨盆间的关系,改变重力的作用,改变与分娩进程有 It is controversial whether maternity should be limited to a position during maternal delivery or to limit maternal activity. At the end of the nineteenth and early twentieth centuries, some scholars believed that the maternal restriction to a body position is an overcorrential measure that prolongs the labor process, maternal fatigue, the first abnormalities and maternal agony. With the development of perinatal medicine, the safety of mothers, fetuses and infants is receiving more and more attention. Whether there are too many human interventions in obstetric work remains the current concern. Maternal body position is one of them. In addition to the three factors of labor, birth and fetus during labor, maternal posture or positioning should also be considered in order to get a more complete picture of the delivery process. It is as important as the other three factors in deciding whether or not a woman can spontaneously deliver. Maternal body position can change the contractions, the relationship between the fetus and the pelvis, change the role of gravity, change and delivery process
