Why are fetal scalp blood oxygen tensions such a poor guide to the state of the fetus ? That they are "unhelpful" has been noted by GULIN, ESCARCENA and POSE [12], KERENJI, FALK, METTEL and WALKER [17] and ourselves in $n earlier paper [23]. Yet fetal oxygen tensions do alter with maternal oxygen tensions — both in blood and in tissue particularly when the maternal level falls [3, 9, 10, 18, 19, 28, 32, 36]. In many cases of fetal acidosis, however, oxygen tensions in scalp blood are normal, even when acidosis is profound (pH < 7.00) and hypercapnia marked. This paper reports full blood-gas and acidbase measurements in 38 cases of fetal acidosis and attempts to explain the findings.
