The objectives of the study were to assess the ability of a fetal pulse oximeter to measure the fetal oxygen saturation (SPO2) continuously during labor and to assess the correlation between readings of fetal pulse oximetry and cord blood gases at birth. The Nellcor N-400 Fetal Oximeter was used in 62 women prospectively. The mean SPO2 was unchanged at the different stages of normal labor. 53.3 +/- 9.1 to 50.1 +/- 11.8% (n = 50). The SPO2 recorded during the pushing phase of stage II (n = 40) was correlated significantly with umbilical cord arterial pH (r = 0.55; p = 0.0002), venous pH (r = 0.63; p = 0.0001), venous PCO2 (r = 0.47; p = 0.002) and venous PO2 (r = 0.39; p = 0.01). SPO2 was also correlated with scalp pH (r = 0.52; p < 0.05; n = 21). No side effects were noted. Fetal pulse oximetry could be useful to assess fetal oxygenation during labor and at birth.
本研究的目的是评估胎儿脉搏血氧仪在分娩期间连续测量胎儿血氧饱和度（SPO2）的能力，并评估胎儿脉搏血氧测定读数与出生时脐血气之间的相关性。前瞻性地对62名妇女使用了Nellcor N - 400胎儿血氧仪。在正常分娩的不同阶段，平均SPO2没有变化。从53.3±9.1%至50.1±11.8%（n = 50）。第二产程用力阶段记录的SPO2（n = 40）与脐动脉pH（r = 0.55；p = 0.0002）、静脉pH（r = 0.63；p = 0.0001）、静脉PCO2（r = 0.47；p = 0.002）和静脉PO2（r = 0.39；p = 0.01）显著相关。SPO2也与头皮pH相关（r = 0.52；p < 0.05；n = 21）。未观察到副作用。胎儿脉搏血氧测定法可能有助于评估分娩期间和出生时的胎儿氧合情况。
