[FBA and/or CTG: fetal blood analysis and/or cardiotocography].

"The Ranking and Value of Intrapartum Cardiotocography--A Contribution to the Efficiency of the Method", and "Overrating of Cardiotocography and Negative Clinical Effects", two round-table discussions on specialist congresses during 1982/1983, prompted a controversial discussion on the subject: Intensive Care during Pregnancy and Delivery via FBA (foetal blood analysis) and/or CTG (cardiotocography)? In two recently published papers originating from the working team of Professor Saling, Hammacher's score was used as measure for assessing the value of cardiotocography. Hence, the author has been both prompted and challenged to this editorial not only as the inaugurator, but also as "interpretative acrobat" of cardiotocography. In his opinion, the overrated use of FBA represents an additional risk to the foetus due to possible compressions of the umbilical cord--placenta circulation because of the artificial rupture of the membranes which is often necessary when performing FBA.

Significance of oscillation frequency in intrapartum fetal monitoring.

Until now, no statistical data have been available on the significance of the frequency of FHR oscillations. In order to evaluate the relation between oscillation frequency and neonatal outcome, the last 30 minutes of 812 FHR records were analyzed with respect to the number of 812 FHR records were analyzed with respect to the number of oscillations per minute only. Close correlations were found between slow oscillations below 2 per minute and the arterial cord pH as well as the Apgar scores after 1 and 5 minutes, respectively.
