OBJECTIVE We describe the development of an alternative approach to intraoperative magnetic resonance imaging (iMR)-guided neurosurgery and report our initial experience with 22 craniotomies and 16 brain biopsies. The advantages and disadvantages of each approach are examined. METHODS An iMR suite houses a 0.2-T open configuration system (Siemens Medical(More)
OBJECT Cerebral hemispherectomy for intractable seizures has evolved over the past 50 years, and current operations focus less on brain resection and more on disconnection. In addition, cases involving cortical dysplasia and Rasmussen encephalitis are being identified and surgically treated in younger individuals. Few studies have been conducted to compare(More)
OBJECT Encephaloduroarteriosynangiosis (EDAS) is a form of revascularization that has shown promising early results in the treatment of adult patients with moyamoya disease (MMD) and more recently in patients with intracranial atherosclerotic steno-occlusive disease (ICASD). Herein the authors present the long-term results of a single-center experience with(More)
OBJECTIVE We evaluated a combined technique designed for procedures requiring intraoperative language mapping. We planned to induce general anesthesia with endotracheal intubation and hyperventilation and then to awaken and extubate the patient for speech testing. After the latter, endotracheal reintubation and general anesthesia were planned. METHODS(More)
Since the development of the WHO Safe Surgery Saves Lives initiative and Surgical Safety Checklist, numerous hospitals across the globe have adopted the use of a surgical checklist. The UCLA Health System developed its first extended Surgical Safety Checklist in 2008. Authors of the present paper describe how the time-out checklist used before skin incision(More)
We describe a case of propylene glycol toxicity due to intravenous administration of etomidate for cerebral protection. A continuous etomidate infusion was titrated to burst suppression of the electroencephalogram during surgical resection of a large intracranial arteriovenous malformation. The etomidate formulation used (Amidate, Abbot) contains etomidate(More)
Medical histories for 105 consecutive children who underwent selective posterior rhizotomy (SPR) were reviewed to determine the incidence and clinical significance of adverse events related to anaesthesia and surgery. No intraoperative or postoperative events with potential for lasting morbidity, nor life threatening events, were identified.(More)
OBJECTIVES Reducing variability is integral in quality management. As part of the ongoing Encephaloduroarteriosynangiosis Revascularisation for Symptomatic Intracranial Arterial Stenosis (ERSIAS) trial, we developed a strict anaesthesia protocol to minimise fluctuations in patient parameters affecting cerebral perfusion. We hypothesise that this protocol(More)
There is little information available concerning the alterations in skeletal muscle energy metabolism which occur in response to chronic arterial occlusive disease. In addition, the effect of arterial reconstruction on skeletal muscle energy metabolism in patients with peripheral vascular disease has not been defined. Needle biopsies were obtained from the(More)
OBJECTIVE In July 2011, the UCLA Health System released its current time-out process protocol used across the Health System. Numerous interventions were performed to improve checklist completion and time-out process observance. This study assessed the impact of the current protocol for the time-out on healthcare providers' safety attitude and operating room(More)
