Owing to the frequent use of bedside ultrasound, much is known about the regulation of and normative values for amniotic fluid volume and the mechanisms by which this fluid is regulated. The management protocols for conditions with extremes of amniotic fluid volume have become more exact, resulting in interventions more likely to improve outcome. Much is still unclear; there are no tools to measure amniotic fluid volume with precision, and measurement of fetal urinary output is cumbersome and error-prone.
由于经常使用床边超声，人们对羊水体积的调节和正常值以及调节羊水的机制有了更多的了解。羊水体积极值情况下的管理方案变得更加精确，从而使干预措施更有可能改善结果。但仍有许多不清楚的地方；没有工具可以精确测量羊水体积，而胎儿尿量的测量既繁琐又容易出错。
