The effect of focal twitching on the intracranial pressure during paralysis and mechanical ventilation.
Three patients with head injuries developed minor facial twitching while their intracranial, intrathoracic and systemic arterial pressures were being monitored and they were on mechanical ventilation. These twitches were disclosed by the coincided great and damaging increases in the intracranial pressure, while the intrathoracic and arterial pressures were virtually unchanged. The intracranial hypertension was attributed to cerebral vasodilatation which was presumed to be due to the accumulation of cerebral metabolites since other causative factors such as systemic hypertension and hypoxia were under control. Cerebral elastance modulated the rise in intracranial pressure.
