Serial transabdominal amniocentesis was performed on eight mares in late gestation. Ultrasonography was used to identify the two placental fluid sacs and the foetus. A biopsy guide attached to the transducer allowed visualisation of the needle path during insertion. Amniotic fluid was obtained in 85 per cent of the attempts, although as mares approached parturition substantial pools of amniotic fluid were more difficult to locate. Two mares aborted during the study probably because of complications of the procedures, whereas six mares produced normal foals at term. The abortions preclude clinical use of this technique currently. However, there was sufficient success in retrieval of amniotic fluid and outcome of pregnancies to continue the study of amniocentesis in larger groups of mares to determine the clinical and research value of this technique.
在妊娠晚期，对8匹母马进行了经腹连续羊膜穿刺术。使用超声检查来识别两个胎盘液囊和胎儿。连接在换能器上的活检导向器可在穿刺过程中显示针的路径。85%的穿刺尝试获得了羊水，不过随着母马临近分娩，大量羊水池更难定位。在研究过程中有两匹母马流产，可能是由于手术并发症，而另外六匹母马足月产下了正常的马驹。目前这些流产事件使该技术无法用于临床。然而，在获取羊水方面有足够的成功率以及妊娠结局，足以继续在更大数量的母马群体中研究羊膜穿刺术，以确定该技术的临床和研究价值。
