Is the correlation between fetal oxygen saturation and blood pH sufficient for the use of fetal pulse oximetry?
None of three cases with pH below 7.05 would have been detected using mean SpO2 over the last 30 min prior to fetal scalp blood sampling or delivery. Only one case would have been detected using the lowest SpO2 measurement over this period. We conclude that fetal SpO2 measurements during labor are of poor diagnostic value, with a disappointing feasibility and therefore are not ready for implementing into daily clinical practice.
Our finding that the HDL-C level in this population was higher than the previously reported levels in Turkey indicates that HDL-C levels may not be as low as previously thought. We believe that lower HDL-C levels that were previously reported might be due to the difference between techniques of analysis, nutritional status, and percent of subjects who were fasting in the day of analysis or improper subject inclusion which did not reflect the Turkish population causing selection bias.
