Case ReportsReversible cerebral vasoconstriction syndrome with limb myoclonus following intravenous administration of methylergometrine.
Neurological deficits associated with methylergometrine have been reported primarily as a result of reversible cerebral vasoconstriction syndromes (RCVS). RCVS are characterized by reversible multifocal vasoconstrictions of the cerebral arteries heralded by acute severe headache with or without neurological deficits. Here, we present the first case of suspected RCVS with transient limb myoclonus following the intravenous administration of methylergometrine during cesarean section. ⋯ No abnormalities were detected by brain computerized tomography, magnetic resonance imaging, and electroencephalogram. She fully recovered spontaneously within 12 h. We consider that the transient limb myoclonus in our patient appeared as a result of RCVS caused by the intravenous administration of methylergometrine.

Duration of cerebral desaturation time during single-lung ventilation correlates with mini mental state examination score.
Single-lung ventilation (SLV) is thought to reduce regional cerebral oxygen saturation (rSO(2)). In this study, we evaluated changes in rSO(2) during SLV and their correlation with perioperative changes in cognitive function. ⋯ Duration of cerebral desaturation time during SLV correlates with MMSE score. Additional studies are needed to determine whether intervention against cerebral desaturation during SLV can prevent postoperative cognitive dysfunction.
