Ketamine has neuroprotective characteristics as well as beneficial cardiocirculatory properties and may thus reduce vasopressor consumption. In contrast, sedation with ketamine (like any other sedative drug) has side effects. This study assesses the influence of ketamine on intracranial pressure (ICP), on the consumption of vasopressors in induced hypertension therapy, and on the occurrence of delayed cerebral ischemia (DCI)-associated cerebral infarctions, with particular focus on the complications of sedation in patients with aneurysmal subarachnoid hemorrhage (SAH). ⋯ Ketamine decreases the ICP and is not associated with a higher rate of complications. The rate of DCI-associated cerebral infarctions was lower in the ketamine group. Ketamine administration led to a reduction of vasopressors used for induced hypertension.

Case Reports
Traumatic Frontal Epidural Hematoma Caused by Multiple Arterial Injuries in the Anterior Fossa.
This case report illustrates the need to evaluate the possibility of multiple arterial sources when presented with a frontal epidural hematoma associated with facial trauma. ⋯ We report a case of an epidural hematoma caused by 2 distinct arterial feeders. We discuss radiologic review and operative management of anterior fossa epidural hematomas and stress the importance of considering arterial bleeding from sources other than the middle meningeal artery in anterior fossa epidural hematomas. We discuss the utility of preoperative angiography for these patients and reinforce the need for acute postoperative imaging to ensure successful operative and patient outcomes.

Case Reports
Ultrasonography monitoring with Superb Microvascular Imaging technique in brain tumor surgery.
Neuronavigation based on preoperative magnetic resonance imaging has been developed as a useful tool to improve visibility of the surgical site in the operative field. Ultrasonography (US) monitoring has also been used as a reliable imaging technique, providing real-time information during neurosurgical operations. We combined the latest innovative imaging technique for detecting very low-flow components, Superb Microvascular Imaging (SMI), with US monitoring during brain tumor surgery. ⋯ We combined SMI technique with US monitoring during brain tumor surgery and observed healthy and tumor vessels. Further research is important for the development of a more precise and reliable neurosurgery.

The primary objective of this study is to examine the effects smoking status on rhBMP-2 supplementation in spinal fusion constructs. ⋯ While rhBMP-2 supplements arthrodesis of instrumented lumbar fusion constructs, smoking status ascertains the strongest predictor of reoperation for pseudarthrosis, instrumentation failure, and adjacent segment.

The Western Cape Province of South Africa has a great shortage of diagnostic expertise, rehabilitative infrastructure, and support services for patients with traumatic brain injury (TBI). The neurosurgical outpatient setting is busy and often chaotic, and patients are frequently lost to follow-up. This study sought to continue with the design and development of a comprehensive, yet brief tool to aid patient referrals and ensure that no consequence of TBI is left unidentified and unaddressed. ⋯ The findings further highlight the prevalence of the cognitive, behavioral, and psychological consequences of TBI and shed additional light on the particular types of problems that patients with TBI face. Following the identified changes, the questionnaire and algorithm combination are now ready to be validated in the neurosurgical clinical setting.
