SCALP BLOOD GAS ANALYSIS - 07/09/11
Résumé |
The fetal blood sample (FBS) was introduced into clinical practice for pH measurements by Saling38 in 1962 as the first invasive fetal monitoring tool. This methodology was an important step forward for understanding the effect of labor on blood gas homeostasis of the human fetus and for defining the importance of fetal heart rate (FHR) patterns2, 25 revealed by continuous FHR measurement techniques, which were introduced at about the same time.18
Although the use of FBS has been widely advocated to improve the specificity of FHR monitoring, it remains an unpopular procedure7 because it is inconvenient for both the clinician and mother and invasive for the mother and fetus. Consequently, the frequency of its use varies dramatically from Europe to North America, from unit to unit, and even within the same unit dependent on individual clinicians. Physicians who embrace it in their practices would gladly give it up; however, it currently remains the only inexpensive practical procedure (with a physiologic basis and an evidence base) to clarify complex and uncertain patterns found on continuous FHR monitoring.
