The most important acute neurological diseases seen at neurosurgery departments are traumatic brain injuries (TBI) and subarachnoid hemorrhages (SAH). In both diseases the pathophysiological sequela are complex and have not been fully understood up to now, and rodent models using rats and mice are most suitable for the investigation of the pathophysiological details. In both models, surgery is performed under anesthesia, followed by assessment of their functional outcome and behavioral testing before brain tissue analysis after euthanasia...

The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) provides a rich database of North American surgical procedures and their complications. Yet no external source has validated the accuracy of the information within this database. Using records from the 2006 to 2013 NSQIP database, we used two methods to identify errors: (1) mismatches between the Current Procedural Terminology (CPT) code that was used to identify the surgical procedure, and the International Classification of Diseases (ICD-9) post-operative diagnosis: i...

Background: Chronic subdural hematoma (CSDH) is a very common clinical emergency encountered in neurosurgery. While both general anesthesia (GA) and monitored anesthesia care (MAC) can be used during CSDH surgery, MAC is the preferred choice among surgeons. Further, while dexmedetomidine (DEX) is reportedly a safe and effective agent for many diagnostic and therapeutic procedures, there have been no trials to evaluate the safety and efficacy of DEX vs. sufentanil in CSDH surgery. Objective: To evaluate the safety and efficacy of DEX vs...

Background: Approximately 60% of patients experience moderate-to-severe pain after neurosurgery, which primarily occurs in the first 24-72 h. Despite this, improved postoperative analgesia solutions after neurosurgery have not yet been devised. This retrospective study was conducted to evaluate the effect of intra- and post-operative infusions of dexmedetomidine (DEX) plus sufentanil on the quality of postoperative analgesia in patients undergoing neurosurgery. Methods: One hundred and sixty-three post-neurosurgery patients were divided into two groups: Group D (DEX infusion at 0...

The Pediatric Anesthesia Neuro Development Assessment (PANDA) team at the Anesthesiology Department at Columbia University Medical Center held its fifth biennial symposium to discuss issues regarding potential neurotoxicity of anesthetic agents in pediatric patients. Overall optimal surgical timing as well as a "critical window" for surgery on a specialty specific basis are areas of focus for the American Academy of Pediatrics Surgical Advisory Panel. An ad hoc panel of pediatric surgical experts representing general surgery, urology, neurosurgery, and ophthalmology was assembled for this meeting and provided a dialogue focused on the benefits of early intervention versus potential anesthetic risk, addressing parental concerns, and the need for continued interdisciplinary collaboration in this area...

OBJECTIVE: Neurosurgery in general anesthesia exposes patient to hemodynamic alternations both in prone and sitting position. As the comparison of the sitting and prone position in neurosurgery is scarce, we aimed to evaluate hemodynamic profile during stroke volume-directed fluid administration in patients undergoing neurosurgery either in sitting or prone position. METHODS: Thirty patients in prone and 28 in sitting position in two separate prospective trials were randomized to receive either Ringer's Acetate (RAC) or hydroxyethyl starch (HES 130 kDa/0...

Since 2011, data on patients exposed to direct oral anticoagulants (DOAs) while undergoing invasive procedures have accumulated. At the same time, an increased hemorrhagic risk during perioperative bridging anticoagulation without thrombotic risk reduction has been demonstrated. This has led the GIHP to update their guidelines published in 2011. For scheduled procedures at low bleeding risk, it is suggested that patients interrupt DOAs the night before irrespective of type of drug and to resume therapy six hours or more after the end of the invasive procedure...

The aim of this prospective observational study was to evaluate the performance of lung ultrasound (LUS) in detecting post-operative atelectasis in adult patients under general anesthesia. Forty-six patients without pulmonary comorbidities who were scheduled for elective neurosurgery were enrolled in the study. A total of 552 pairs of LUS clips and thoracic computed tomography (CT) images were ultimately analyzed to determine the presence of atelectasis in 12 prescribed lung regions. The accuracy of LUS in detecting peri-operative atelectasis was evaluated with thoracic CT as gold standard...

REVIEW
Mazda K Turel, Mark Bernstein
The current trend in all fields of surgery is towards less invasive procedures with shorter hospital stays. The reasons for this change include convenience to patients, optimal resource utilization, and cost saving. Technological advances in neurosurgery, aided by improvements in anesthesia, have resulted in surgery that is faster, simpler, and safer with excellent perioperative recovery. As a result of improved outcomes, some centers are performing brain tumor surgery on an outpatient basis, wherein patients arrive at the hospital the morning of their procedure and leave the hospital the same evening, thus avoiding an overnight stay in the hospital...

Hypertensive patients in neurosurgery are becoming more common, which increased the risk of surgical stress response. Meanwhile, the relationship between hypertension and anesthesia methods is unclear on the stress response. The purpose of this study is to compare the effect of different anesthesia methods on high-sensitivity C-reactive protein (Hs-CRP), blood glucose, and leucocyte levels in neurosurgical patients with hypertension or normal.Eighty neurosurgical patients were randomly divided into 4 groups (n = 20): balanced anesthesia group (A), balanced anesthesia with hypertension group (B), total intravenous anesthesia group (C), total intravenous anesthesia with hypertension group (D)...

REVIEW
Samuel Grodofsky
This review includes a summary of contemporary theories of pain processing and advocates a multimodal analgesia approach for providing perioperative care. A summary of various medication classes and anesthetic techniques is provided that highlights evidence emerging from neurosurgical literature. This summary covers opioid management, acetaminophen, nonsteroidal antiinflammatories, ketamine, lidocaine, dexmedetomidine, corticosteroids, gabapentin, and regional anesthesia for neurosurgery. At present, there is not enough investigation into these areas to describe best practices for treating or preventing chronic pain in neurosurgery; but providers can identify a wider range of options available to personalize perioperative care strategies...

BACKGROUND: Quantitative estimates of surgical capacity and infrastructure, as well as perceived care limitations in low -resource countries are essential baseline measures that can provide strategies for improving access to surgical care. Information about these barriers in Africa is scarce, particularly with respect to neurosurgery. We conducted a survey to better understand the unmet surgical need and resources available for the care of neurosurgery patients in sub-Saharan Africa. METHODS: Using SurveyMonkey®, we administered a neurosurgery-specific survey to neurosurgery attendings and residents in sub-Saharan African countries...

TOPICALITY: The fast track technology means a complex of targeted measures involving rational preoperative preparation, minimally invasive surgery, regional anesthesia and short-acting anesthetics, and early postoperative rehabilitation. Elucidating the possibility of applying the fast track technology in neurosurgery, in particular in spinal surgery, is extremely topical. This is associated with the epidemiological data and the fact that minimally invasive techniques used in neurosurgery are highly expensive...

OBJECTIVE Historically, performing neurosurgery with the patient in the sitting position offered advantages such as improved visualization and gravity-assisted retraction. However, this position fell out of favor at many centers due to the perceived risk of venous air embolism (VAE) and other position-related complications. Some neurosurgical centers continue to perform sitting-position cases in select patients, often using modern monitoring techniques that may improve procedural safety. Therefore, this paper reports the risks associated with neurosurgical procedures performed in the sitting position in a modern series...

Although neuroprotection to contain the initial damage of spinal cord injury (SCI) is difficult, multicentre studies show that early neurosurgery under general anaesthesia confers positive benefits. An interesting hypothesis is that the general anaesthetic itself might largely contribute to neuroprotection, although in vivo clinical settings hamper studying this possibility directly. To further test neuroprotective effects of a widely used general anaesthetic, we studied if propofol could change the outcome of a rat isolated spinal cord SCI model involving excitotoxicity evoked by 1 h application of kainate with delayed consequences on neurons and locomotor network activity...

Intracraneal hypotension headache is a well known syndrome in neurosurgery practice. In most cases cerebrospinal fluid leaks are caused by medical interventions, such as lumbar puncture, peridural anesthesia and surgical interventions on the spine. Clinical symptoms tipically show orthostatic headache that resolves in supine position, and other symptoms like neck tightness, vertigo and diplopia. RMI diagnostic confirms paquimeningeal enhancement and subdural hygromas. Conservative treatment usually includes bed resting, hydratation and administration of caffeine or glucocorticoids, resolving spontaneously in one to four months...

In the past decade, the New World common marmoset (Callithrix jacchus) has taken a seminal position in neurobiological research, fueled in part by its smooth cortical sheet, which allows cortical areas to be easily accessed by current technologies on the dorsal surface of the brain. In this protocol, we describe a method for the precision placement of agents (e.g., tracers or neurotoxins) into small brain regions of the infant and adult marmoset, using an MRI-guided approach. This strategy uses a protocol for prolonged anesthesia without the need for intubation that we have recently developed, alongside appropriate analgesia and monitoring...
