The aim of this study was to determine whether there are any changes in short time variation (STV), foetal movements, and blood flow in the umbilical artery in the trance state.
Six pregnant patients who had already attended two hypnoreflexogenous birth preparation course units had a standardised hypnosis intervention under cardiotocography (CTG). Using the CTG-Player ((R)) STVs and foetal movements were calculated from the electronically saved CTG traces and evaluated against control CTGs recorded before and after hypnosis. Before and after the induction of hypnosis, blood flow in the umbilical artery was measured.
Using the Wilcoxon test there is a significant lowering of blood flow resistance in the umbilical artery after hypnosis (p=0.042). There was a trend that the foetal movements increas at the beginning of the trance (Wilcoxon test, p=0.075). There was no significant difference in the STVs before, during and after trance.
Preliminary results showed that blood flow of the umbilical artery can be improved by hypnosis. Further clinical studies are required to verify this hypothesis. The subjective impression of participants that foetal movements increase at the beginning of the trance seems to be correct.
本研究的目的是确定在催眠状态下，短时间变异性（STV）、胎动和脐动脉血流是否存在任何变化。
六名已参加过两个催眠反射性分娩准备课程单元的孕妇在胎心监护（CTG）下接受标准化催眠干预。使用CTG-Player软件从电子保存的CTG记录中计算STV和胎动，并与催眠前后记录的对照CTG进行评估。在催眠诱导前后，测量脐动脉血流。
使用Wilcoxon检验，催眠后脐动脉血流阻力显著降低（p=0.042）。在催眠开始时胎动有增加的趋势（Wilcoxon检验，p=0.075）。在催眠前、催眠期间和催眠后，STV没有显著差异。
初步结果表明，催眠可以改善脐动脉血流。需要进一步的临床研究来验证这一假设。参与者认为在催眠开始时胎动增加的主观印象似乎是正确的。
