Popis: | The deceleration delay index (DDI) is a statistical parameter computed by an on-line system which analyzes fetal monitor output for the temporal relationship between each uterine contraction and any associated deceleration of the fetal heart rate. A similar parameter describing this relationship is known to be quantitatively predictive of fetal oxygenation in the rhesus monkey, a species for which the level of fetal oxygenation is also known to be directly and progressively related to aberrations in the vital signs, to brain damage, and to fetal death. Thus, the DDI should be of significant, practical value in predicting fetal hypoxia at a time early enough to avert severe neonatal depression and/or hypoxic brain damage. A blind clinical trial of 106 parturients is presented which supports this concept by showing the DDI to be highly correlated with another oxygenation-associated parameter, the one-minute Apgar score. |
