In view of the release in May 2001 of the United Kingdom of the Royal College of Obstetricians and Gynaecologists (RCOG)/National Institute for Clinical Excellence (NICE) Guidelines on the use of electronic fetal monitoring 6 (which included a comprehensive bibliography an Evaluating the value of intrapartum fetal scalp blood sampling to predict adverse neonatal outcomes: A UK multicentre observational study Al Wattar, Bassel H. et al. European Journal of Obstetrics and Gynecology and Reproductive Biology, Volume 240, 62 - 6 The fetal blood sample (FBS) was introduced into clinical practice for pH measurements by Saling 38 in 1962 as the first invasive fetal monitoring tool. This methodology was an important step forward for understanding the effect of labor on blood gas homeostasis of the human fetus and for defining the importance of fetal heart rate (FHR) patterns2, 25 revealed by continuous FHR measurement.

Fetal scalp blood sampling is a test of historical importance as it was developed as a supplementary tool to intermittent auscultation with the Pinard stethoscope. It was subsequently used as an additional test of fetal wellbeing to reduce the false positive rate of CTG. However, to justify FBS in modern obstetric practice the obstetrician must. Fetal blood sampling (FBS) is a proce-dure carried out in labour in which a sample of capillary blood is obtained from the fetal scalp using an amnioscope. The Royal College of Obstetricians and Gynaecologists (RCOG) recommends that hospitals using electronic fetal moni-toring (EFM) by cardiotocograph tracin

the pH decreases in the hypoxic process and therefore serves as an early marker (RCOG, 2015). Fetal pH and lactate samples can be measured by fetal scalp blood sampling. Lactate is now the preferred measurement. Fetal lactate samples are more likely to be successfully performed, require fewer scalp incisions, and need a smaller amount of blood.

Fetal blood sampling (FBS) and fetal scalp electrode (FSE) should be avoided in babies expected to have severe or moderate haemophilia. In babies potentially affected with mild haemophilia, judicious use of FBS and FSE can be considered, in order to facilitate vaginal delivery and avoid morbidity associated with caesarean section in labour Continuous cardiotocography (CTG) Of the 409 babies where fetal monitoring was identified as a critical contributory factor by one or more reviewer, continuous CTG interpretation and/or its subsequent management was a significant contributory factor to the outcome for 341 babies. 47 of these babies had critical factors identified in both. Similarly fetal scalp blood sampling or the use of intrapartum scalp electrodes may increase the risk of bleeding. There is little data to inform the management of breech presentation at term in the context of haemophilia. However, there would be similar concerns regarding the potential for ICH in association with external cephalic version or.

Fetal scalp blood sampling is considered a useful fetal monitoring tool to prevent neonatal morbidity and mortality. In the delivery room, fetal scalp blood testing is performed to assess, with high specificity, birth asphyxia as a consequence of impaired oxygenation. This condition is a threat to the fetus and may require immediate. Fetal scalp blood sampling (FBS) is proposed as an objective test to assess the fetal metabolic status in labour, measuring capillary pH and base excess values, thus prompting further interventions when fetal acidaemia is suspected. The trainees of the UKARCOG network appreciate the help and guidance received from consultants on the RCOG.

A sample of blood is taken from the fetal scalp using an amnioscope and is subjected to blood gas analysis. The test has its short comings: it can be difficult to perform at cervical dilatation <3 cm; skill is required to ensure a good quality sample; and the procedure may be stressful and appear as an unnecessary intervention to the mother

The use of a vacuum is not contraindicated following a fetal blood sampling procedure or application of a fetal scalp electrode. [New 2020] Grade of recommendation: B. Operators should be aware that there is a higher risk of subgaleal haemorrhage and scalp trauma with vacuum extraction compared with forceps at preterm gestational ages A fetal scalp blood pH level of less than 7.20 is considered abnormal. In general, low pH suggests that the baby does not have enough oxygen. This may mean that the baby is not tolerating labor very well. The results of a fetal scalp pH sample need to be interpreted for each labor Where possible, fetal scalp electrodes and fetal scalp sampling should be avoided in women with HCV. Consensus-based recommendation Recommendation 5 Grade and reference As for all blood borne infections, it is recommended to bath the baby to remove any maternal body secretions and blood prior to IM injections e.g. vitamin K.

Fetal scalp lactate sampling resulted in statistically significant improvements in the success rate of fetal blood sampling (i.e., the testing meter was able to analyze the blood sample) when compared to fetal scalp pH testing. 2 The authors of the clinical trial that assessed this outcome attributed a majority of the failed samplings with a pH. Fetal blood sampling. This involves taking fetal scalp blood into capillary tubes for analysis of fetal pH and/or lactate. Acquiring samples can be time-consuming, can be difficult, and may fail to yield an adequate sample for analysis. Additionally, it can be falsely reassuring in the presence of chorioamnionitis or thick meconium

All fetal scalp blood estimations should be interpreted taking into account the previous measurement, the rate of progress in labour and the clinical features of the mother and baby.

Intrapartum fetal asphyxia is the presence of hypoxia during labor resulted in fetal acidosis and depression of vital functions and an increased risk of long-term morbidity [].Electronic fetal heart rate monitoring (EFM) during labor with a cardiotocography (CTG) was established as cornerstone in fetal surveillance [].Although normal results indicate that the fetus is getting enough oxygen. She may also take a tiny sample of blood from your baby's scalp (a fetal blood sample). The blood sample will be tested to see if your baby is getting enough oxygen (NCCWCH 2011, 2014). This is the best indicator of how your baby is coping with labour (NCCWCH 2014). To take a blood sample, your doctor will ask you to lie on your left side. 2019. Al Wattar, Bassel H. et al.

Percutaneous umbilical blood sampling (PUBS) or fetal scalp blood sampling is not recommended, as it is not helpful in predicting neonatal thrombocytopenia and is potentially harmful In the newborn, the platelet count reaches its nadir 2-5 days after delivery and rises spontaneously by day Amniocentesis (also referred to as an amniotic fluid test or, informally, an amnio) is a medical procedure used primarily in prenatal diagnosis of chromosomal abnormalities and fetal infections as well as for sex determination.In this procedure, a small amount of amniotic fluid, which contains fetal tissues, is sampled from the amniotic sac surrounding a developing fetus Fetal Scalp Blood Sampling Until recently fetal scalp blood sampling (FBS) was not practised in nearly 50% of the delivery units in the U.K 16, and even when the facilities exist, it is not used in all cases 6. This could be due to the difficulties in obtaining a sample when the head is high, or the cervix is not sufficiently dilated 16, or. In view of its very poor positive predictive value for metabolic acidosis and a high false positive rate, CTG requires additional tests of fetal wellbeing such as fetal scalp blood sampling, (FBS), fetal scalp lactate, fetal pulse oximetry and fetal electrocardiograph (fetal ECG also called STAN or ST-analyser)

Cardiotocography (CTG) is a technical means of recording the fetal heartbeat and the uterine contractions during pregnancy.The machine used to perform the monitoring is called a cardiotocograph, more commonly known as an electronic fetal monitor (EFM).. Fetal monitoring was invented by doctors Alan Bradfield, Orvan Hess and Edward Hon.The cardiotocograph is a refined form of fetal monitoring. It is advisable to leave the fetal membranes intact till late in labour to reduce the risk of cord prolapse. The fetal scalp electrode and fetal blood sampling use is contraindicated prior to 34 weeks gestation and hence any suspicious fetal monitoring trace should be considered as indication for caesarean section Evidence-based information on pre operative blood tests from Cochrane Database of Systematic Reviews for health and social care.
