Fetal Scalp Blood Sampling

This article reviews existing clinical practices and sensor research undertaken to monitor fetal well-being during labour. Current clinical practices that include fetal heart rate monitoring and fetal scalp blood sampling are shown to be either inadequate or time-consuming. Monitoring of lactate in blood is identified as a potential alternative for intrapartum fetal monitoring due to its ability to distinguish between different types of acidosis. A literature review from a medical and technical perspective is presented to identify the current advancements in the field of lactate sensors for this application. It is concluded that a less invasive and a more continuous monitoring device is required to fulfill the clinical needs of intrapartum fetal monitoring. Potential specifications for such a system are also presented in this paper.

Fetal Scalp Blood Sampling

During a 3-month period, 1,062 mother-infant pairs were studied for infections following internal fetal monitoring during labor. Six infants (0.56%) developed septic scalp dermatitis at the site of the spiral electrode application. Factors associated with septic scalp dermatitis included the number of vaginal examinations, the use of an intrauterine pressure catheter or of more than one spiral electrode, and fetal scalp blood sampling. Maternal diabetes and endomyometritis were also associated with an increased risk of scalp infection. The duration of spiral electrode use and duration of ruptured membranes were not significant risk factors. Endomyometritis was documented in 41 mothers, an overall incidence of 3.9%. In women whose babies were delivered by cesarean section, the incidence of endomyometritis was 28/117 (23.9%). Using multivariate analysis by logistic regression, endomyometritis was associated with the number of vaginal examinations during labor but not with the duration of internal monitoring, duration of labor, or duration of ruptured membranes.

Intrapartum Fetal Monitoring

Antenatal surveillance and intrapartum fetal monitoring are routine components of obstetric care, particularly in the high-risk patient. The goal of antenatal testing is to reduce stillbirths in pregnancies with heightened risk. The goal of intrapartum monitoring is to reduce fetal acidemia, which can lead to asphyxia and long-term neurologic sequelae. Both antepartum and intrapartum monitoring of the fetal heart rate and its variability are sensitive to acidemia. Standard nomenclature exists for describing the features of fetal heart rate tracing. Ultrasonography is a useful adjunct to fetal heart rate monitoring, particularly for antenatal testing. The decision to initiate antenatal testing or intrapartum monitoring depends on many factors, particularly gestational age and maternal status. All forms of surveillance have high false-positive rates and poor positive predictive value. If the results of abnormal testing will not affect clinical management, testing should not be performed.

Fetal Scalp Blood Sampling

The paper presents an overview of current russian and foreign literature considering fetal monitoring in labor. Special attention is paid to the methods of invasive diagnostics of fetal condition, such as direct fetal electrocardiography with ST-segment analysis and fetal scalp blood sampling. A comparison of the effectiveness of these methods is performed, the incidence of complications is provided. Measurement of pH and lactate in fetal scalp blood samples is discussed.

ABSTRACT Objectives To evaluate the role of intrapartum vibroacoustic stimulation (VAST) and cardiotocography (CTG) for the prediction of neonatal outcome. Materials and methods One hundred and twenty-five patients in labor with cephalic presentation were selected and subjected to CTG and VAST was done further to find out whether fetus is reactive or nonreactive and findings were correlated with the fetal outcome. Results VAST is a good predictor of fetal well being. It is less time consuming, inexpensive and technically easy to perform. In developing countries, where fetal scalp blood sampling is not available in all institutions, VAST can effectively be used as a clinical tool to compliment abnormal CTG traces for better prediction of fetal outcome.
