Hippocampal N-methyl-D-aspartate receptors (NMDARs) are thought to be involved in the regulation of memory formation and learning. Investigation of NMDAR function during experimental conditions known to be associated with impaired cognition in vivo may provide new insights into the role of NMDARs in learning and memory. Specifically, the mechanism whereby(More)
We reviewed the results of intraoperative monitoring of short-latency cortical evoked potentials in 81 patients who underwent surgical procedures of the cervical spine. Of these patients, 43 had baseline somatosensory evoked potentials from stimulation of the upper and lower extremities, intraoperative monitoring for at least 3 hours, and absence of an(More)
Because of a suspicion that intraoperative penicillin antibiotics might be causing early postoperative seizures in craniotomy patients, a deliberate effort was initiated in 1987 to avoid these agents in favor of nonpenicillin antibiotics. This permitted a retrospective comparison of the incidence of early postoperative seizures in craniotomy patients who(More)
Failure to awaken after general anesthesia is a rare complication that may be caused by residual drug effect, systemic abnormalities, or neurologic injury. Failure to awaken often is initially attributed to residual drug effect, potentially delaying correct diagnosis. Three cases of failure to awaken because of neurologic injury are reviewed. Differential(More)
A prospective, randomized study was performed in 87 patients to compare the safety, efficacy and dose requirements of two sedation techniques for stereotactic headframe application. Sedation administration and headframe application averaged 30 min. Fifty patients weighing 76 +/- 13 kg (mean +/- SD) received mean doses of 154 micrograms fentanyl plus 5.5 mg(More)
