Midazolam is a short-acting water soluble benzodiazepine that has been used with an increasing frequency in the last years. Although there are reports on its use in status epilepticus, there is none in the neonatal period. A pre-term (35 w) AGA newborn infant with a severe hypoxic-ischemic encephalopathy secondary to grade III hyaline membrane disease… (More)
Digital EEG (DEEG) and quantitative EEG (QEEG) are recently developed tools present in many clinical situations. Besides showing didactic and research utility, they may also have a clinical role. Although a considerable amount of scientific literature has been published related to QEEG, many controversies still subsist regarding its clinical utilization.… (More)
Neurophysiological evaluation of patients in coma through multimodality sensory evoked potentials: general aspects. SUMMARY — Noninvasive sensory evoked potentials (SEP) performed at bedside in the Intensive Care Unit for patients in coma can be helpful in establishing both a diagnosis and a prognosis. Based on a more than 6-year experience on this subject,… (More)
Noninvasive sensory evoked potentials (SEP) performed at bedside in the Intensive Care Unit for patients in coma can be helpful in establishing both a diagnosis and a prognosis. Based on a more than 6-year experience on this subject, the authors discuss general aspects concerning these EP, their probable known generators, and propose a classification… (More)
Brazilian Clinical Neurophysiology Society guidelines and pertaining comments concerning electroencephalogram (EEG) recording in suspected brain death are presented. EEG is not intended as a substitute, rather as a complement to neurologic evaluation.
OBJECTIVE Better definition of normal amplitude asymmetry values on the classical EEG frequency bands. RESULTS EEG amplitude asymmetry index (AAI) is physiologically low in normal adults, differences usually lesser than 7%. CONCLUSION Persistent or intermittent amplitude asymmetry regional differences higher than 7% may be suggestive of pathology after… (More)
Based upon the results observed in 15 patients submitted to tumor resection by the CO2 microlaser technique and submitted to brain stem auditive evoked potential (BAEP) intraoperative determination, the authors emphasize the importance of the technique. BAEP during the intraoperative period and the ultrasonic control of removal of tumors proved useful in… (More)
