The clinical course is characterized by right upper quadrant and epigastric pain, hypertension, proteinuria and edema. Maternal and neonatal morbidity are high. The underlying cause for this pregnancy-related syndrome is still unclear. As soon as a reliable diagnosis is established handling of patients suffering from HELLP-Syndrome is ambivalent: Immediate termination of pregnancy, however, poses a problem at early gestational age. Therefore some authors have advocated a conservative management. At our department active management and delivery by Caesarean section as soon as possible has gained acceptance in the past 5 years. We report our experience with 23 patients over a 12 year period, and with 4 patients from the intensive care unit (N = 27). Mean gestational age was 33.5 weeks (+/- 4.8) and the mean birthweight was 1922.5 g (+/- 971.5). 19 patients were delivered by Caesarean section. Most complications were based on a delayed delivery and subsequent deterioration of maternal condition. Reduction of the time interval between establishment of diagnosis and termination of pregnancy (1980-1985-3 days; 1986-1992-12 hours) resulted in a better outcome.

Therefore we looked for a new method to quantify the de novo-synthesis of H(+)-ions due to both pathways and to correlate them with the clinical condition of the newborn.</p><p><strong>Methods: </strong>Using pH-, pCO2 (mmHg)- (and pO2 (mmHg)) measurements in umbilical blood (artery (UA), vein (UV)) of 8882 newborns, which were delivered vaginally in vertex position without cord-entanglements and without major malformations, the pHqu40 (metabolic pathway) and the pHnm (non-metabolic pathway) were computed. Thus both components of fetal acidosis could be determined together with actual pH in one unity i.e. H(+)-ion-concentration (nmol/l). By introduction of a reference-point, which denotes the mean actual pH- (7.373) and the mean pCO2- (36.4 mmHg) value in umbilical venous blood of 599 Apgar 10-babies it is possible to compute the mean de novo-synthesis of H(+)-ions in different clinical neonatal conditions (Apgar-score 1 min).</p><p><strong>Results: </strong>In the case of slightly depressed neonates (Apgar 7-10) the respiratory acidosis dominates the metabolic one. In moderately asphyxiated newborns (Apgar 4-6) both components are equally involved. In severe fetal asphyxia (Apgar 0-3) both components can probably be determined by extrapolation: the metabolic component seems to be dominant.

This means, that actual pH-measurements are of high clinical importance in severely asphyxiated newborns. They should not be abandoned.

The pressure values were correlated to various obstetric variables. Typically, the head pressure remained elevated beyond the end of the uterine contraction in primiparae, whereas it decreased simultaneously with the amniotic pressure in multiparae. On the average, the head pressure was higher in primiparae indicating, together with the longer lasting bearing down period, a higher resistance of the birth canal. Deliveries with pudendal block or peridural analgesia showed no differences, but these two groups differed in other factors which might have influenced the results. Infusion of oxytocin during the course of labor was associated with higher head pressure values that could not be deduced from the hormone administration per se, but from a higher resistance of the birth canal. Maternal age did not influence the head pressure.
