Fetal scalp sampling in labour.
In the linked randomised controlled trial, Wiberg-Itzel and colleagues compare the effectiveness of two methods of diagnosing hypoxia in the fetus during labour— scalp pH analysis and scalp lactate analysis.1 Fetal wellbeing during labour depends on several factors—an adequate supply of oxygenated maternal blood reaching the placental intervillous space, gas exchange across an undamaged placent...
متن کاملLactate analyzer with continuous blood sampling for monitoring blood lactate during physical exercise.
To monitor changes in the concentration of blood lactate during physical exercise, we used an automated lactate analyzer based on an electro-enzymatic method with continuous blood sampling through a catheter. The lactate concentration was measured every 2 min; between measurements, the instrument was calibrated with a lactate standard. Ascorbic acid, bilirubin, hemoglobin, creatinine, uric acid...
متن کاملAmnioscopy and foetal blood sampling: observations on foetal acidosis.
Amnioscopy is available as an out-patient procedure, whenever hazards threaten the life of the foetus during late pregnancy. An endoscope-the amnioscope-is passed into the cervical canal so that the amniotic fluid can be inspected through the intact forewaters. Amniotic fluid which is clear, or milky from emulsification of vernix, indicates that conditions within the uterus are normal. Green or...
متن کاملFactors influencing the pH value of foetal scalp blood with special reference to caput succedaneum.
Foetal loss and neonatal death rate are still challenges to obstetricians. Several techniques have been developed to estimate the foetal well-being in utero-the pH determination of the foetal blood being one of these. The technique has been described by Saling' and Morris and Beard.'" Several reports showed the reliability of this technique in predicting the Apgar score of the foetus."" There a...
متن کاملRupture of the foetal heart during labour.
