Anesthetics are widely used in the management of neurocritical patients, although has never been proved that the use of these drugs can contribute to positive outcome. The aim of this review was to evaluate the expected benefit of anesthetics use in relation to the altered physiology of the damaged brain while considering possible related complications.
BACKGROUND Functional Magnetic Resonance Imaging (fMRI) is often used in preoperative assessment before epilepsy surgery, tumor or cavernous malformation resection, or cochlear implantation. As it requires complete immobility, sedation is needed for uncooperative patients. OBJECTIVE The aim of this study was to compare the fMRI cortical activation pattern(More)
KEY POINTS The mechanisms of action of anaesthetics on the living brain are still poorly understood. In this respect, the analysis of the differential effects of anaesthetics on spontaneous and sensory-evoked cortical activity might provide important and novel cues. Here we show that the anaesthetic sevoflurane strongly silences the brain but potentiates in(More)
STUDY OBJECTIVE To assess the safety of mechanical ventilation and effectiveness of extrinsic positive end-expiratory pressure (PEEP) (PEEPe) in improving peripheral oxygen saturation (SpO2) during direct microlaryngeal laser surgery; to assess the incidence, amount, and nature (dynamic hyperinflation or airflow obstruction) of ensuing intrinsic PEEP(More)
We report on the incidence of complications of 172 internal jugular vein retrograde catheterizations (IJVRCs) performed on 126 patients. Standard cannulation and X-ray control of the catheter tip placement were performed. Difficulties encountered during the manouvre were registered. Patients with a jugular catheter in place for more than one day had neck(More)
BACKGROUND No technique can be considered as a gold standard for ventilation during direct laser CO2 laryngeal microsurgery. We evaluated the feasibility of standard ventilation with laser-safe endotracheal tubes (ETTs) and inspired O2 fraction (FiO2) = 0.21 during direct microlaryngoscopy. METHODS During total intravenous anesthesia, standard mechanical(More)
Intravenous hypertonic fluid therapy has been proposed to improve secondary ischemic injury after cerebrospinal trauma. We report the case of a 14-year-old boy with vasospasm of the intracranial vertebral arteries and ischemic brain stem damage following head trauma. The patient presented with severe tetraparesis and somatosensory (SSEPs) and brain stem(More)
Magnetic resonance imaging (MRI) requires patient immobility and children generally need to be sedated. The ideal sedative agent for functional MRI (fMRI) should only minimally hamper the neurophysiologic effect of the administered sensorial stimulation. This study compares the effect of propofol and midazolam on the fMRI auditory activation pattern in(More)
