A retrospective study to determine how well cardiotocogram (CTG) and micro blood analysis (FBA) results correspond to each other was made on 200 deliveries which had been monitored sub partu by these techniques. FBA was performed 306 times. CTG results were analysed according to Hammacher's method and the scores compared with the FBA results. In 40 cases with a normal Hammacher score, a normal ...

OBJECTIVE To study interobserver agreement in the assessment of intrapartum automated fetal electrocardiogram ST interval analysis (STAN). DESIGN Observational study. SETTING Labor ward in tertiary level university hospital. Sample. Two hundred (140 reassuring and 60 non-reassuring) STAN recordings on non-selected women with singleton, vertex, term pregnancies were selected from our archive...

BACKGROUND The rate of caesarean sections around the world is rising each year, reaching epidemic proportions. Although many caesarean sections are performed for concerns about fetal welfare on the basis of abnormal cardiotocography, the majority of babies are shown to be well at birth, meaning that the operation, with its inherent short and long term risks, could have been avoided without comp...

OBJECTIVE To examine detailed intrapartum events in cases of neonatal metabolic acidosis despite monitoring using STAN (cardiotocography [CTG] plus ST waveform analysis of fetal electrocardiogram [ECG]). DESIGN Retrospective case review. SETTING High-risk pregnancies monitored by STAN. METHODS Case note review was performed in newborns with metabolic acidosis where no significant ST chang...

OBJECTIVE To determine whether short time variation (STV) of fetal heart beat correlates with scalp pH measurements during labor. PATIENTS AND METHODS From 1279 deliveries, 197 women had at least one fetal scalp pH measurement. Using the CTG-Player, STVs were calculated from the electronically saved cardiotocography (CTG) traces and related to the fetal scalp pH measurements. RESULTS There ...
