“…The end point of fetal EEG deterioration as established by this series, the work of Rosen (1967) on the fetal guinea pig and Mann et a1 (1970, 1971 and 1972) on the fetal lamb, is a trace in which there is loss of all wave frequencies and an amplitude of under 2 pv. Previously described as 'iso-electric' or 'flat', the American Electroencephalographic Society (1976) has recommended that this change in the EEG be known as electrocerebral silence (ECS).…”

We investigated the effect of head compression and acidaemia during labour in 25 African primigravidae. Evidence that head compression had occurred during labour was confirmed by both clinical and radiological means at the end of a trial of labour. No significant difference could be demonstrated in the quantity of fetal electroencephalogram (EEG) abnormality that occurred in the groups with marked head compression as compared to the groups without marked head compression. Deterioration in the fetal EEG to a flat record known as electrocerebral silence (ECS) was associated with the development of acidaemia. As fetal heart rate (FHR) decelerations appeared the percentage of ECS in the fetal EEG record increased significantly (P < 0.05), and likewise, as fetal acidaemia developed a highly significant increase in ECS in the fetal EEG was demonstrated (P < O*OOl). We concluded that in the management of trial of labour there was no significant deleterious change in the fetal EEG as a result of head compression, unless fetal acidaemia supervened. However, in the majority of these cases a significant increase in ECS to more than 20 per cent occurred in association with only moderate acidaemia (pH 7.25 to 7.30).CEPHALOPELVIC disproportion remains a major obstetrical hazard in developing countries and contributes significantly to perinatal death rates. In many cases disproportion and fetal asphyxia co-exist and make the exact cause of death difficult to determine. Perinatal statistics from Harare Hospital, Salisbury reveal that between 15 to 20 per cent of perinatal deaths are due to 269

“…The group tried different techniques. They initially reported the use of metal skin clips soldered to a shielded cable, coated with non-conductive plastic glue, and filed at their tip to prevent deep scalp penetration (51). This type of electrodes was replaced by cup electrodes, initially with a platinum needle embedded in a lucid disc (49, 51) (with possible skin penetration of 1-2 mm), later replaced by a central silver or platinum pin avoiding penetration of the fetal skin (31).…”

“…The two major problems associated with intrapartum fEEG precluding its routine use were technical issues and data interpretation. Placement of electrodes over the occipital area is the area where electrodes are most easily applied but because the occiput is a relatively quiet electrical area of the brain, the parietal area is preferred (51). Because of the limited space, there is only a limited number of electrodes that can be placed precluding comparison of homologous areas of the brain (51).…”

“…The effect of forceps birth on fetal brain activity was also evaluated (15,26,33,34,51). FEEG recorded during labor involving forceps application required placement of the two electrodes along the sagittal suture and between the fontanelles to avoid the forceps blade (compared to their placement over the parietal region for normal birth) (15).…”

“…However, because the majority of the eligible studies, particularly the ones in humans, reported mainly descriptive findings, this turned out to be extremely challenging. Indeed, a lot of these studies just described fEEG traces of selected cases (19,22,26,33,39,40,42,(49)(50)(51)60). In fact, only 4 studies analyzed the fEEG in relation to the outcome at 1 year and are from the same group (with the same cohort for all but one study) (27)(28)(29)31).…”

Monitoring Fetal Electroencephalogram Intrapartum: A Systematic Literature Review

et al. 2020

Background: Studies about the feasibility of monitoring fetal electroencephalogram (fEEG) during labor began in the early 1940s. By the 1970s, clear diagnostic and prognostic benefits from intrapartum fEEG monitoring were reported, but until today, this monitoring technology has remained a curiosity. Objectives: Our goal was to review the studies reporting the use of fEEG including the insights from interpreting fEEG patterns in response to uterine contractions during labor. We also used the most relevant information gathered from clinical studies to provide recommendations for enrollment in the unique environment of a labor and delivery unit.
