Abstract：
In numerous medical conditions, including pregnancy, gravity and posture interact to impact physiology and pathophysiology. Recent investigations, for example, pertaining to maternal sleeping posture during the third trimester and possible impact on fetal growth and stillbirth risk highlight the importance and potential clinical implications of the subject. In this review, we provide an extensive discussion of the impact of maternal posture on fetal physiology from conception to the postpartum period in human pregnancy. We conducted a systematic literature search of the MEDLINE database and identified 242 studies from 1991 through 2021, inclusive, that met our inclusion criteria. Herein, we provide a synthesis of the resulting literature. In the first section of the review, we group the results by the impact of maternal posture at rest on the cervix, uterus, placenta, umbilical cord, amniotic fluid, and fetus. In the second section of the review, we address the impact on fetal-related outcomes of maternal posture during various maternal activities (e.g., sleep, work, exercise), medical procedures (e.g., fertility, imaging, surgery), and labor and birth. We present the published literature, highlight gaps and discrepancies, and suggest future research opportunities and clinical practice changes. In sum, we anticipate that this review will shed light on the impact of maternal posture on fetal physiology in a manner that lends utility to researchers and clinicians who are working to improve maternal, fetal, and child health.
摘要：
在许多医疗条件下，包括怀孕,重力和姿势相互作用，影响生理学和病理生理学。最近的调查,例如,关于孕妇在妊娠中期的睡眠姿势以及对胎儿生长和死产风险的可能影响突出了该受试者的重要性和潜在的临床意义。在这次审查中,我们提供了广泛的讨论，从怀孕到产后期间，母亲的姿势对胎儿生理的影响。我们对MEDLINE数据库进行了系统的文献检索，并确定了1991年至2021年的242项研究，符合我们的纳入标准。在这里，我们提供了所得文献的合成。在回顾的第一部分，我们通过产妇休息姿势对子宫颈的影响对结果进行分组，子宫,胎盘,脐带,羊水,还有胎儿.在审查的第二部分，我们讨论了在各种产妇活动期间产妇姿势对胎儿相关结局的影响(例如，睡眠,工作,锻炼)，医疗程序(例如，生育力,成像,手术），分娩和分娩。我们介绍已发表的文献，突出差距和差异，并建议未来的研究机会和临床实践的变化。总之,我们预计，这篇综述将揭示产妇姿势对胎儿生理的影响，从而为致力于改善产妇的研究人员和临床医生提供实用性，胎儿,和儿童健康。
