The frequency of uterine contractions was studied in 37 patients with severe abruptio placentae. They ranged from 3 to 16 per 10 minutes, with a mean of 7,86. When frequency of contraction was correlated with haematological and clinical data, a slight negative correlation was found between the frequency and haemoglobin and haematocrit values. In patients with intra-uterine fetal death, the mean frequency was 8,85 as opposed to 5,55 when the infant was born alive. This difference is statistically significant. The possible role of these abnormal contractions is causing intra-uterine death is discussed.
对37例重度胎盘早剥患者的子宫收缩频率进行了研究。收缩频率为每10分钟3至16次,平均为7.86次。当收缩频率与血液学和临床数据相关联时,发现频率与血红蛋白及血细胞比容值之间存在轻微的负相关。对于宫内胎儿死亡的患者,平均频率为8.85次,而婴儿存活时平均频率为5.55次。这种差异具有统计学意义。文中讨论了这些异常收缩在导致宫内死亡方面可能发挥的作用。
