时间可能受穿刺中得到的细胞数量的影响,因此,增加羊水中羊水细胞浓度的技术有可能缩短培养时间。1990年Carlan等的一项研究中,尝试增加下沉羊水细胞的悬浮,孕妇随意在检查床上或转体360℃或不转体,该研究未能表明母亲的活动对羊水细胞浓度或培养时间有好处。此调查的目的是评价遗传学羊膜穿刺术前用手对子宫处理的影响。
The time may be affected by the number of cells obtained in puncturing, and therefore, techniques that increase amniotic fluid cell concentration in amniotic fluid may shorten the incubation time. In a 1990 study by Carlan et al., Attempting to increase the suspension of sunken amniotic fluid cells, pregnant women were randomly placed in bed or swirling at 360 ° C or without swiveling, the study failed to show that mothers’ motility was negatively correlated with amniotic fluid cell concentration or culture time benefit. The purpose of this survey was to evaluate the effects of hand-on-uterine treatment prior to genetic amniocentesis.
