OBJECTIVES: We aimed at evaluating the predictive value of amniotic fluid index ≤5 on perinatal outcome in terms of effect on cardiotocography, mode of delivery, meconium in liquor, birth weight, fetal distress, APGAR score at birth and neonatal admission to ICU. METHODS: This is a prospective study of 308 antenatal women admitted to labor ward of MIMS during February 2014-December 2015 with gestational ages between 34 and 41 weeks. All women enrolled were subjected to history taking, examination, AFI estimation and compared between those with AFI ≤5 from rest...

Cardiotocography (CTG) is a technique used to monitor intrapartum fetal condition and is one of the most common obstetric procedures. Second line methods of fetal monitoring have been developed in an attempt to reduce unnecessary interventions due to continuous cardiotocography and to better identify fetuses at risk of intrapartum asphyxia. The acid-base balance of the fetus is evaluated by fetal blood scalp samples, the modification of the myocardial oxygenation by the fetal ECG ST-segment analysis (STAN) and the autonomic nervous system by the power spectral analysis of the fetal heart variability...

OBJECTIVE: To evaluate the ability of intrapartum ultrasound to differentiate occipitoposterior (OP) rotation with normal flexion of the head from deflexion, to compare the accuracy of ultrasound with the digital examination, and to assess the outcome of labor according to the type of presentation. PATIENTS AND METHODS: A retrospective study of patients with abnormal labor because of either prolongation and/or abnormal cardiotocography and OP rotation who underwent intrapartum sonography...

Continuous intrapartum fetal monitoring remains a significant clinical challenge. We propose utilising cohorts of routinely collected data. We aim to combine non-classical (data-driven) and classical cardiotocography (CTG) features with clinical features into a system (OxSys), which generates automated alarms for the fetus at risk of intrapartum hypoxia. We hypothesise that OxSys can outperform clinical diagnosis of 'fetal distress', when optimised and tested over large retrospective datasets MATERIAL AND METHODS: We studied a cohort of 22,790 labouring women (≥36 weeks gestation)...

OBJECTIVE: To analyze the effect of maternal betamethasone given for fetal lung maturation on fetal short-term variation (STV) and average acceleration and deceleration capacity (AAC/ADC). Both of these factors are calculated by phase-rectified signal averaging (PRSA) and represent new parameters to assess the fetal autonomic nervous system. STUDY DESIGN: A longitudinal prospective study including 26 pregnant women at risk for preterm delivery was performed. Two injections of 12mg betamethasone were administered intramuscularly at a 24h interval for lung maturation...

AIM: To rule out maternal and pregnancy factors that may contribute to platelet count (PLT) changes in the first trimester of gestation and examine if there is any association between its levels and adverse perinatal outcome. METHODS: The study population included all patients from the first-trimester visit between 2013-2015 with pregnancy results. Linear multiple regression was constructed to rule out variables that may have a significant contribution to PLT. For each adverse outcome at birth, multiple logistic regression analysis was implemented to estimate the PLT effect...

Cardiotocography (CTG) has disappointingly failed to show good predictability for fetal acidemia or neonatal outcomes in several large studies. A complete rethink of CTG interpretation will not be out of place. Fetal heart rate (FHR) decelerations are the most common deviations, benign as well as manifestation of impending fetal hypoxemia/acidemia, much more commonly than FHR baseline or variability. Their specific nomenclature is important (center-stage) because it provides the basic concepts and framework on which the complex "pattern recognition" of CTG interpretation by clinicians depends...

Cardiotocography (CTG) is currently the most often used technique for detection of fetal distress. Unfortunately, CTG has a poor specificity. Recent studies suggest that, in addition to CTG, information on fetal distress can be obtained from analysis of fetal heart rate variability (HRV). However, uterine contractions can strongly influence fetal HRV. The aim of this study is therefore to investigate whether HRV analysis for detection of fetal distress can be improved by distinguishing contractions from rest periods...

Rupture of the uterus is rare but catastrophic. Rupture often results in fetal bradycardia, abdominal pain, haemodynamic changes and vaginal bleeding. A 36-year-old healthy woman, gravida 3, para 1, went into spontaneous labour at gestation age 39 + 4, and at orificium 7 cm she received epidural analgesia. Following the epidural, the fetal heartbeat could not be registered by external cardiotocography, and caput could not be palpated. Spontaneous birth was attempted, but a caesarean section was necessary. The baby was found in the abdomen...

BACKGROUND: The goal of fetal monitoring in labour is the early detection of a hypoxic baby. There are a variety of tools and methods available for intermittent auscultation (IA) of the fetal heart rate (FHR). Low- and middle-income countries usually have only access to a Pinard/Laënnec or the use of a hand-held Doppler device. Currently, there is no robust evidence to guide clinical practice on the most effective IA tool to use, timing intervals and length of listening to the fetal heart for women during established labour...

Monitoring the fetal behavior does not only have implications for acute care but also for identifying developmental disturbances that burden the entire later life. The concept, of 'fetal programming', also known as 'developmental origins of adult disease hypothesis', e.g. applies for cardiovascular, metabolic, hyperkinetic, cognitive disorders. Since the autonomic nervous system is involved in all of those systems, cardiac autonomic control may provide relevant functional diagnostic and prognostic information...

OBJECTIVES: In the recent TRUFFLE study it appeared that, in pregnancies complicated by fetal growth restriction (FGR) between 26 and 32 weeks, monitoring of the ductus venosus (DV) combined with computerised cardiotocography (cCTG) as a trigger for delivery, increased the chance of infant survival without neurological impairment. However, concerns in interpretation were raised as DV monitoring appeared associated with a non-significant increase in fetal death, and part of the infants were delivered after 32 weeks, after which the study protocol was no longer applied...

Timely recognition and appropriate management of high-risk pregnancies, such as intrauterine growth restriction (IUGR), are of paramount importance for every obstetrician. After the initial screening of IUGR fetuses through sonographic fetometry and Doppler, the focus is shifted to the appropriate monitoring and timing of delivery. This can, especially in cases of early IUGR, become a very difficult task. At this point, cardiotocography (CTG) is introduced as a major tool in the day-to-day monitoring of the antenatal well-being of the IUGR fetus...

BACKGROUND: Unnecessary routine interventions in uncomplicated labour and birth, like cardiotocography (CTG), amniotomy, use of scalp electrode and oxytocin treatment, are associated with further interventions that could harm the woman and the infant. A four year Action Research (AR) project was done on a labour ward to enhance the capacity of local midwives in the promotion of physiological labour and birth. AIM: To describe the use of interventions during labour and birth in healthy women at term with spontaneous onset of labour, before and after initiation of an Action Research project...
