Veränderung des Gefäßwiderstands der Arteria umbilicalis, der fetalen Bewegung und der Herzzeitvariation durch Hypnose – Erste Ergebnisse

Abstract

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.

Change of Spectral Analysis of Fetal Heart Rate During Clinical Hypnosis: a Prospective Randomised Trial from the 20th Week of Gestation Till Term

“…Heart rate results showed that the heart rate is slightly lower with increased standard deviation during hypnosis. These results support previous studies, which indicate that the fetus is more active during hypnosis [13]. Similar to previous studies [21,34], in our study fetal HRV changed with gestational age.…”

“…In our study increased fetal LFnu and decreased fetal HFnu can only be explained as secondary sympathetic reaction to the maternal hypnosis. In previous studies the increased fetal movements are consistent with this reaction to hypnosis [13,24,48], rather than the expected parasympathetic reaction of the fetus of deep relaxation like the mother [36,44,45].…”

“…Furthermore typical reflex responses of the parasympathetic nervous system only begin at term and reach adult levels after birth [22]. Fetal LF and HF bands are influenced by the behavioural state [23], but results of our study group also showed an effect of fetal behavioural state depending on the state of the pregnant women [13,24]. Recently, a non-invasive abdominal fetal electrocardiogram (ECG), which provides true beat-to-beat evaluation with good signal quality [25][26][27], has been approved for clinical usage from the 20th week of gestation onwards.…”

“…The hypnotisability varies from person to person, but is higher during pregnancy [7]. The ability to influence and access function beyond conscious control is increased during the hypnotic state [8,9], which might proof beneficial in preterm labour [10][11][12] and might be able to influence the blood flow of the A. umbilicalis [13]. The autonomic nervous system is altered during hypnosis which includes acute [14] and chronic [15,16] (after hypnotherapy) changes.…”

Hypnotherapie, Gestationsalter und Frühgeburtenrate

“…M ö gliche Wirkmechanismen der hypnotherapeutischen Technik k ö nnten die St ä rkung der Immunabwehr durch Hypnose sein [33] , die Reduktion der erlebten Stressbelastung und die F ö rderung der Angstbew ä ltigung [24,25] . Obwohl immer h ä ufi ger objektive Eff ekte einer Hypnotherapie in der Geburtshilfe nachgewiesen werden konnten [27,28,34,35] , ist noch nicht endg ü ltig gesichert, ob sich in der vorliegenden Studie tats ä chlich nur ein spezifi scher Eff ekt der Hypnotherapie manifestiert. Diese Frage kann jedoch nur durch eine prospektive randomisierte Studie gekl ä rt werden.…”
