Researchers at the University of Warwick, and the University Hospitals Coventry and Warwickshire NHS Trust, have devised a new sensor which dramatically improves the amount of early warning doctors and midwives get of a dangerous situation in the birth process when the unborn child's brain is starved of oxygen - Fetal Hypoxia.
The threat of fetal hypoxia carries dangers not only for the child but also for the woman giving birth as doctors often proceed quickly to a caesarean section if they feel there is a significant threat of fetal hypoxia. However current tests for this condition require blood samples to be taken to a lab for examination leading to delays which means doctors having to decide sometimes to proceed with a cesarean section rather than take the risk on waiting on that full analysis.
University of Warwick researcher Professor Nick Dale had been looking at the science surrounding a chemical that can be found in blood called hypoxanthine. An unborn child with more than 5 micromoles (5 millionths of a mole) of hypoxanthine per litre of their blood is at severe risk of fetal hypoxia. Professor Dale was frustrated at the lack of effective instrumentation available to detect and study this chemical and devised his own fine tuned probe to examine the chemical. On talking with colleagues in the University of Warwick's Medical School and University Hospitals Coventry and Warwickshire NHS Trust they pointed out that the probes would be of massive benefit to doctors in the delivery room.
