Cerebral oxygenation and regional cerebral perfusion responses with resistance breathing during central hypovolemia.
Resistance breathing improves tolerance to central hypovolemia induced by lower body negative pressure (LBNP), but this is not related to protection of anterior cerebral blood flow [indexed by mean middle cerebral artery velocity (MCAv)]. We hypothesized that inspiratory resistance breathing improves tolerance to central hypovolemia by maintaining cerebral oxygenation (ScO2), and protecting cer...
متن کاملCerebral tissue oxygenation index and SIDS.
In this issue of Pediatrics, Fyfe et al present convincing evidence that cerebral tissue oxygenation index (TOI) is lower in habitually supinesleeping preterm infants placed prone rather than supine, and that the cerebral TOI for preterm infants placed prone is lower than the TOI for term infants placed prone. Increased rates of sudden infant death syndrome (SIDS) among all infants sleeping pro...

متن کاملRegional cerebral hyperperfusion associated with postictal paresis.
The pathophysiology of postictal paresis and other symptoms of Todd's phenomenon are not fully understood. Various hypotheses about its mechanism include exhaustive neuronal firing, desensitization, and active suppression. This case series demonstrates CT perfusion findings of two patients with postictal paresis that show hyperperfusion, increased cerebral blood flow, increased cerebral blood v...
متن کاملCranial Doppler resistance index measurement in preterm newborns with cerebral white matter lesion.
OBJECTIVE To investigate whether the resistance index (RI) within the first 72 hours of life of newborn infants with cerebral white matter lesion (WML) is correlated with the adverse outcome of WML. METHODS Retrospective study. Newborn infants with WML were identified based on cranial ultrasound results, and those with Doppler imaging and RI measurement were selected. The newborn infants were...
