Clinical TrialContinuous monitoring of fetal oxygen saturation by pulse oximetry.
To compare spectrophotometric saturation values of fetal blood sampling to the saturation readings by pulse oximetry. ⋯ Fetal pulse oximetry corresponds satisfactorily to results from fetal blood analysis. Low invasiveness and continuous monitoring are the advantages of this method. At present, the available sensor generates only a limited amount of signal time. However, in combination with FHR monitoring, pulse oximetry promises greatly improved detection of fetal hypoxia.

To describe eight cases of postpartum women who developed seizures associated with post-dural puncture headache. ⋯ We propose that cerebral vasoconstriction is the mechanism for post-dural puncture headaches and seizures. Anatomic brain displacement may incite this vasospasm. This mechanism could also be the cause of cranial nerve palsies that have been described after dural puncture.
