Assessment of brain dysfunction in head injured patients is important as an index of severity of brain damage and forms the basis of monitoring. . The Glasgow Coma scale (G.C.S.) is a practical scale for nurses. The Liege Coma scale contains the three variables of the G.C.S. and provides informations concerning the brain stem reflexes. In a series of 60(More)
The effects of two calculated plasma sufentanil (SUF) concentrations on the hemodynamic and bispectral index (BIS) responses to Mayfield head holder (MH) application were studied in 20 patients scheduled for intracranial surgery. Premedication consisted of hydroxyzine, alprazolam, and atropine given orally 1 hour before surgery. Anesthesia was provided with(More)
The object of this study was to determine whether the addition of information on brain stem reflexes improves the prognostic precision of the Glasgow coma scale for patients with severe head trauma. The study is based on 109 patients with a Glasgow coma score of 7 or less during the first 24 hours after injury. The average age was 23 years. The patients(More)
The effect of propofol on the toxicity induced by glutamate (GLU), N-methyl-D-aspartate (NMDA), kainate (KA), and amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) was investigated on cultured fetal rat hippocampal neurons. The degree of neuronal injury was quantified by measuring the release of the neuron-specific enolase (NSE) into the culture(More)
BACKGROUND Through their action on the locus coeruleus, alpha2-adrenoceptor agonists induce rapidly reversible sedation while partially preserving cognitive brain functions. Our goal in this observational study was to map brain regions whose activity is modified by clonidine infusion so as to better understand its loci of action, especially in relation to(More)
A new method of intraoperative localisation of the primary motor cortex is described, based on the application of single anodal electric pulses to the brain surface. Patients were anaesthetised with propofol infusion, and neuromuscular blockade was temporarily alleviated to allow recording of surface EMG responses (CMAPs) to the stimuli. Primary motor areas(More)
This clinical report investigated the potential benefit of acute normovolemic hemodilution (ANH) as a blood-saving technique in the surgical repair of craniosynostosis. Over a 4-year period, 34 healthy children undergoing surgical repair of scaphocephaly or pachycephaly were randomly assigned to two groups of 17 patients each. Patients of the first group(More)
We separately studied the antioxidant properties of propofol (PPF), Diprivan (the commercial form of PPF) and intralipid (IL) (the vehicle solution of PPF in Diprivan) on active oxygen species produced by phorbol myristate acetate (10(-6) M)-stimulated human polymorphonuclear leukocytes (PMN: 5 x 10(5) cells/assay), human endothelial cells (5 x 10(5)(More)
We describe the target-controlled administration of propofol and remifentanil, combined with monitoring of the bispectral index, during an awake craniotomy for removal of a left temporo-parietal tumour near the motor speech centre. Target concentrations of the two drugs were adjusted according to the patient's responses to painful stimuli and surgical(More)
This study is based on 109 patients with severe head injury who had a Glasgow coma score equal to or less than 7 and a Liège coma score equal to or less than 12 in the first 24 hours. The syndrome of inappropriate secretion of antidiuretic hormone seems to us to be a frequent complication of severe craniocerebral trauma. It has been discovered in 33% of our(More)
