Accuracy of intrapartum fetal blood gas analysis by scalp sampling

Fetal blood gas analysis (FBGA) using scalp blood is commonly used to identify serious fetal distress. However, there is a lack of data regarding its accuracy and reliability. The aim of this study was to determine the positive predictive value (PPV) and negative predictive value (NPV) of FBGA for predicting postpartum acidosis in case of nonreassuring fetal heart rate tracings (NRFHRT). To thi...

Breech management with fetal blood sampling.

long-term availability of reprints means that the reports will be more accessible to a wider audience than much work which is conventionally published. One important feature of the I.R.C.S. is that it will provide ready access to work done in non-English-speaking parts of the world. At the mome:nt scitntists from such countries are usually fully aware of what is published in English language jo...

Fetal blood gas analysis at delivery.

Correspondence Fetal blood gas analysis at delivery Sir, In a recent article D'Souza et al.1 note that it is simpler and more convenient to obtain umbilical venous than arterial blood to assess the acid base status of a newborn infant at delivery. They add, however, that sampling arterial blood would be preferable to venous blood as the former reflects more closely the metabolic condition of th...

Changes in transcutaneous oxygen tension during capillary blood-gas sampling.

With a Radiometer TCM-1 oxygen monitor, we followed the fluctuations in transcutaneous oxygen tension (ptcO2) during capillary blood collection from a heel prick. Thirty premature infants who presented with some respiratory compromise showed unpredictably increased (43 of 125 observations) or decreased (82 of 125 observations) values during this blood-sampling process. The fluctuation exceeded ...
