Abstract:

Background: Perinatal asphyxia is a major cause of neonatal and childhood morbidity and mortality. Electronic foetal monitoring is used routinely to know the condition of the baby during Intrapartum period. Normal trace correlates highly with absence of acidemia at birth. Abnormal trace needs further evaluation. In order to better define the metabolic status of the new born, umbilical lactate levels have been measured. Objectives of this study were to determine the validity of umbilical cord blood lactate levels in predicting the adverse early neonatal outcome in babies with intrapartum foetal

Abstract:

Objective. To study the characteristics of oximetry and electrolyte balance of umbilical cord arterial and venous blood in newborns with fetal growth restriction. Patients and methods. Laboratory analysis of oximetry and electrolyte balance in blood samples from the umbilical artery and vein in 40 newborns after vaginal delivery at term and uncomplicated pregnancy (the control group) and in 30 newborns with fetal growth restriction after vaginal delivery at term (the study group) was performed. Results. The analysis revealed that the levels of FHbF, pO2, sO2, FO2Hb, FCOHb, cCa2+ and ctO2 in um

Background: Currently phenylephrine (PE) is recommended to treat hypotension after spinal anesthesia for cesarean delivery (CD). Recently low dose norepinephrine has been proposed as effective alternative with advantage of less depression of maternal heart rate and cardiac output.Methods: This was prospective observational study in women scheduled for CD under spinal anesthesia, patients received either PE 100 µg (group PE) or norepinephrine 8 µg (group NE). Primary objective was to study the difference in umbilical artery pH with use of both drugs. The secondary objectives were to compare mat

Abstract:

Background/Objectives: The optimal anesthetic technique for category 2 and 3 cesarean deliveries remains debated, with concerns about impacts on decision-to-delivery interval (DDI) and perinatal outcomes. This study examined the influence of epidural, spinal, and general anesthesia on DDI, surgical and postoperative complications, and neonatal outcomes. Methods: This prospective cohort study at a tertiary perinatology center enrolled parturient women undergoing category 2 and 3 cesarean deliveries. Three DDI phases were assessed for each anesthetic modality: transfer time (decision for cesarea

Background: Even in low risk mothers, fetal acidosis occurs as in high risk groups. Aim of fetal monitoring is to detect early response to intrauterine hypoxia and prevent irreversible neurological damage and death. Objective of this study was to correlate the intrapartum fetal distress with the help of cardiotocography CTG with umbilical cord blood sampling.Methods: A total 100 consecutive patients attending the labor ward were studied. Immediately at birth, before the baby’s first breath and before delivery of the placenta, the umbilical cord blood was collected as per the standard guideline

Abstract:

Umbilical cord rupture (UCR) in utero is a very rare and critical emergency that can cause fetal death within minutes. A 38-year-old nulliparous woman was admitted at 39 weeks in labour. Sudden watery vaginal discharge and bleeding with a rapid drop in the fetal heart rate to 60 beats/min necessitated an emergency caesarean section. A male infant weighing 2632 g was delivered 21 min after the onset of bradycardia; Apgar scores were 0 and 1 at 1 and 5 min, respectively. He was extremely pale; the umbilical arterial blood pH was 6.89 and haemoglobin was 9.0 g/dL. The umbilical cord had a velamen

Abstract:

Asphyxia during birth is one of the three leading causes of neonatal morbidity and mortality among newborns carried to term. The objective of this study was to evaluate the measurement of the foetal scalp blood pH as a measure of foetal status, evaluating: cord gases, meconium-stained fluid, APGAR score or the need for neonatal resuscitation in pregnant women undergoing caesarean sections. A cross-sectional study was carried out over a period of 5 years (2017–2021) at the Hospital de Poniente (southern Spain). A total of 127 pregnant women participated from whom a foetal scalp blood pH sample

The use of color Doppler ultrasonography provides noninvasive observation, confirmation and quantification of pathophysiological processes in fetoplacental circulation in pregnant patients. By blood vessel mapping and the obtained waves spectral analysis it is possible to evaluate vascular resistency of the fetus blood vessels. The aim of the study was to evaluate cerebral-umbilical pulsatility index ratio in fetal circulation in prediction of fetal distress in patients with preeclampsia. Methods. By measurement of pulsatility indices in medial cerebral and umbilical arteries in

Background: The risks of maternal morbidity and mortality associated with a caesarean section may not be reasonably justified by the degree of neonatal compromise at birth associated with caesarean section done for clinically diagnosed foetal distress. The aim was to study the association of clinical diagnosis of non-reassuring foetal status with umbilical artery acidaemia at birth in women undergoing caesarean section for foetal distress and to evaluate outcomes in neonates born by caesarean section performed for foetal distress.Methods: Prospective observational study of all the women underg
