[Intracranial hypertension related to sedation with sevoflurane using the AnaConDa(®) device in a patient with severe traumatic brain injury]. / Hipertensión endocraneal asociada a la sedación con sevoflurano mediante el dispositivo AnaConDa(®)en un paciente con traumatismo craneoencefálico severo.

ABSTRACT

Sedation in neurocritical patients remains a challenge as there is no drug that meets all the requirements. Since the appearance of the AnaConDa(®) device, and according to the latest recommendations, sevoflurane has become an alternative for patients with brain injury. The use of AnaConDa(®) produces an increase in the anatomical dead space that leads to a decrease in alveolar ventilation. If the decrease in the alveolar ventilation is not offset by an increase in minute volume, there will be an increase in PaCO2. We report the case of a patient with severe traumatic brain injury who suffered an increase in intracranial pressure as a result of increased PaCO2 after starting sedation with the AnaConDa(®) device.
