Abstract

We describe a 13-year-old child who developed inadvertent intraoperative cerebral oxygen desaturation attributed to empiric hyperventilation during posterior fossa craniotomy, diagnosed by jugular venous oximetry. Although restoration of normocapnia at age-appropriate mean arterial blood pressure improved jugular venous saturation (SjvO), it remained below acceptable values. Transcranial-Doppler (TCD) ultrasonography-guided stepwise increase in mean arterial pressure led to a linear increase in the mean flow velocity of the middle cerebral artery and SjvO₂ to desirable values. Intraoperative SjvO₂ monitoring and TCD ultrasonography may be utilized together to individualize hemodynamic targets and ventilation parameters and maintain adequate cerebral oxygenation during paediatric craniotomies.
