Multicenter StudyCerebrospinal Fluid Glucose and Lactate Levels After Subarachnoid Hemorrhage: A Multicenter Retrospective Study.
In patients with subarachnoid hemorrhage (SAH), abnormalities in glucose and lactate metabolism have been described using cerebral microdialysis. Glucose and lactate concentrations in cerebrospinal fluid (CSF) are more easily accessible, but scarce data are available in this setting. The aim of this study is to assess the relationship of CSF glucose and lactate with blood concentrations and with unfavorable neurological outcome after SAH. ⋯ CSF glucose and lactate levels poorly correlated with blood concentrations. Low CSF glucose/lactate ratio was associated with poor neurological outcome.

Transient Neurological Events After Surgery for Pediatric Moyamoya Disease: A Retrospective Study of Postoperative Sedation Practices.
Moyamoya disease is a cerebrovascular disease characterized by bilateral stenosis of the intracranial internal carotid arteries and an abnormal collateral vascular network at the base of the brain. Transient neurological events (TNEs), which are episodes of neurological dysfunction lasting <24 hours, are associated with stroke in pediatric patients with Moyamoya disease. Perioperative agitation often occurs in pediatric patients. We hypothesized that anesthetic technique and postoperative sedation would modify the association between TNE and superficial temporal artery-middle cerebral artery (STA-MCA) bypass in pediatric patients with Moyamoya disease. ⋯ In pediatric patients with Moyamoya disease, crying was associated with increased TNE and postoperative sedation is associated with decreased TNE.

Multicenter StudyInternational Multicenter Survey of Perioperative Management of External Ventricular Drains: Results of the EVD Aware Study.
The perioperative management of patients with external ventricular drains (EVDs) is not well defined, and adherence to published management guidelines unknown. This study investigates practice, patterns, and variability in the perioperative management of patients with EVDs. ⋯ The EVD Aware study identifies opportunities for improvement in the perioperative management of patients with EVDS, including global awareness, formal EVD training, and dissemination of educational tools.

Propofol TCI Reductions Do Not Attenuate Significant Falls in Cardiac Output Associated With Anesthesia Induction and Knee-Chest Positioning in Spinal Surgery.
Induction of anesthesia and the knee-chest position are associated with hemodynamic changes that may impact patient outcomes. The aim of this study was to assess whether planned reductions in target-controlled infusion propofol concentrations attenuate the hemodynamic changes associated with anesthesia induction and knee-chest position. ⋯ Planned reductions in propofol concentration do not attenuate anesthesia induction and knee-chest position-related decreases in CO. The knee-chest position is an independent risk factor for decrease in CO. Minimally invasive CO monitors may aid in the detection of clinically relevant hemodynamic changes and guide management in anesthetized patients in the knee-chest position.

This review is intended to provide a summary of the literature pertaining to the perioperative care of neurosurgical patients and patients with neurological diseases. General topics addressed in this review include general neurosurgical considerations, stroke, neurological monitoring, and perioperative disorders of cognitive function.
