The parameters of the intrapartal fetal CTG and the actual pH are related to each other and to the Apgar score of the newborn. The interpretation was carried out by means of groups of 300 to 600 cases. The actual fetal pH has the most compact relation to the Apgar score of the newborn (C equals 0,31). But also this contingence is unsatisfactory. At fetal acidosis most of the Apgar scores are pathological, in that manner the pH is the most important test for indication of operative delivery. The rare CTG pattern as dip II and variable decelerations combined with tachycardia of bradycardia, the bradycardia with 80 bpm or less, are likewise indications of urgent delivery.
