The prevalence of fetomaternal macrotransfusion (FMMT), defined as fetomaternal haemorrhage (FMH) greater than or equal to 10 ml, was calculated in a series of 15,724 postpartum Kleihauer tests recorded in six hospitals. The mean prevalence in this retrospective survey, the largest published to date, was 0.83% (SEM 0.22) but values varied according to the technique used to quantify the volume of FMH. A number of obstetric factors that have been suggested as influencing the occurrence and extent of FMMT were examined. The frequencies of these factors in cases with FMMT were compared with those in a control group without FMMT selected from the same population. Manual removal of the placenta (P less than 0.0001) and fetal distress in labour (P less than 0.0001) occurred significantly more frequently in the case group. We are unable to confirm previous reports that other obstetric factors may influence the occurrence and extent of FMMT.
在六家医院记录的15724例产后克列豪尔试验中，计算了胎儿 - 母体大量输血（FMMT，定义为胎儿 - 母体出血（FMH）大于或等于10毫升）的发生率。在这项迄今为止发表的最大规模回顾性调查中，平均发生率为0.83%（标准误0.22），但根据用于量化FMH量的技术不同，数值有所差异。研究了一些被认为会影响FMMT发生和程度的产科因素。将FMMT病例组中这些因素的频率与从同一人群中选取的无FMMT对照组中的频率进行了比较。病例组中胎盘人工剥离（P<0.0001）和产时胎儿窘迫（P<0.0001）的发生频率明显更高。我们无法证实先前关于其他产科因素可能影响FMMT发生和程度的报道。
