Subanesthetic Dose of Ketamine Improved CFA-induced Inflammatory Pain and Depression-like Behaviors Via Caveolin-1 in Mice
Conclusions: In CFA-treated mice that exhibited pain behavior and depression-like behavior, ketamine reversed depression-like behavior. The prefrontal cortex and nucleus accumbens are the important brain regions in this regulation network. Despite these findings, other molecules and their mechanisms in the signal pathway, as well as other regions of the brain in the pain matrix, require further exploration.

Real-time Monitoring of Cerebral Blood Flow and Cerebral Oxygenation During Rapid Ventricular Pacing in Neurovascular Surgery: A Pilot Study
Conclusions: RVP reduces CBF and cerebral oxygenation. Brain tissue pO2 and regional cerebral oxygenation are correlated but unlike CBF respond to RVP in a delayed manner. Further research is required to evaluate the impact of longer RVP bursts on brain oxygenation. (Source: Journal of Neurosurgical Anesthesiology)

Bilateral Ultrasound-guided Erector Spinae Plane Block for Postoperative Analgesia in Lumbar Spine Surgery: A Randomized Control Trial
Background: Major lumbar spine surgery causes severe postoperative pain. The primary objective of this randomized controlled study was to compare the effect of ultrasound (US)-guided erector spinae plane (ESP) block on 24-hour postoperative cumulative opioid requirements with standard (opioid-based) analgesia. Postoperative pain control and patient satisfaction were also assessed. Materials and Methods: Adults scheduled for elective lumbar spine surgery under general anesthesia were randomly assigned to the following (and they are): Control group-no preoperative ESP block, or ESP block group-preoperative bilateral US-...

Effect of Daytime Versus Night-time on Outcome in Patients Undergoing Emergent Neurosurgical Procedures
Conclusions: This study found no difference in the rate of unfavorable neurological outcome in patients undergoing emergent neurosurgical procedures during the daytime and night-time. However, our findings cannot exclude the possibility of an association between timing of surgery and outcome given its limitations, including small sample size and omission of potentially confounding variables. Further well-designed prospective trials are warranted to confirm our findings. (Source: Journal of Neurosurgical Anesthesiology)

Mannitol Improves Intraoperative Brain Relaxation in Patients With a Midline Shift Undergoing Supratentorial Tumor Surgery: A Randomized Controlled Trial
Background: Mannitol is widely used to reduce brain tissue swelling and improve brain relaxation during neurosurgery. However, the optimal dosage for patients with midline shift undergoing supratentorial tumor resection remains unclear. Methods: In this randomized, controlled double-blinded study, 204 patients with preoperative midline shift who underwent elective supratentorial brain tumor surgery were equally allocated to receive placebo or 0.7, 1.0, or 1.4 g/kg mannitol infusion. The primary outcome was the proportion of satisfactory brain relaxation. Results: Demographics and baseline characteristics wer...

Perioperative Management of Direct Oral Anticoagulants in Intracranial Surgery
The use of direct oral anticoagulants is increasing rapidly, because of perceived benefits over older agents, such as predictable pharmacokinetics and a reduced risk of bleeding. Elderly patients, who are more likely to be prescribed these drugs, are also presenting for neurosurgical procedures more often. The combination of these factors will result in neurosurgeons and neuroanesthesiologists encountering patients prescribed direct oral anticoagulants on an increasingly frequent basis. This review provides a summary of the current evidence pertaining to the perioperative management of these drugs, in the context of electi...

Language Monitoring in Brain Surgery Under General Anesthesia
Conclusions: To our knowledge, this is the first demonstration that phonological processing can be measured during brain surgery under general anesthesia, suggesting that some language processing persists under the condition of unconsciousness. These results encourage further study of language processing under general anesthesia with the goal of making intraoperative neuromonitoring. (Source: Journal of Neurosurgical Anesthesiology)

Pulse Pressure Variations and Plethysmographic Variability Index Measured at Ear Are Able to Predict Fluid Responsiveness in the Sitting Position for Neurosurgery
Background: Pulse pressure variation (PPV) and plethysmographic variability index (PVI), dynamic indicators of preload dependence based on heart-lung interactions, are used to predict fluid responsiveness in mechanically ventilated patients in the supine position. The sitting position for neurosurgery, by changing intrathoracic blood volume, could affect the capacity of PPV and PVI to predict fluid responsiveness. The aim of the study was to assess the ability of PPV and PVI to predict fluid responsiveness during general anesthesia in the sitting position. Methods: In total, 31 patients were included after settling in...

Near-infrared Spectroscopy–derived Cerebral Autoregulation Indices Independently Predict Clinical Outcome in Acutely Ill Comatose Patients
Conclusions: Averaged COx ≥0.05 is independently associated with short and long-term mortality and long-term severe disability in acutely comatose adults with neurological injury. We propose that COx ≥0.05 represents an accurate threshold to predict long-term functional outcome in acutely comatose adults. (Source: Journal of Neurosurgical Anesthesiology)

Perioperative Care of Patients at High Risk for Stroke During or After Non-cardiac, Non-neurological Surgery: 2020 Guidelines From the Society for Neuroscience in Anesthesiology and Critical Care
Perioperative stroke is associated with considerable morbidity and mortality. Stroke recognition and diagnosis are challenging perioperatively, and surgical patients receive therapeutic interventions less frequently compared with stroke patients in the outpatient setting. These updated guidelines from the Society for Neuroscience in Anesthesiology and Critical Care provide evidence-based recommendations regarding perioperative care of patients at high risk for stroke. Recommended areas for future investigation are also proposed. (Source: Journal of Neurosurgical Anesthesiology)

Cerebrospinal Fluid Glucose and Lactate Levels After Subarachnoid Hemorrhage: A Multicenter Retrospective Study
Background: In patients with subarachnoid hemorrhage (SAH), abnormalities in glucose and lactate metabolism have been described using cerebral microdialysis.

Defining a Taxonomy of Intracranial Hypertension: Is ICP More Than Just a Number?
Intracranial pressure (ICP) monitoring and control is a cornerstone of neuroanesthesia and neurocritical care. However, because elevated ICP can be due to multiple pathophysiological processes, its interpretation is not straightforward. We propose a formal taxonomy of intracranial hypertension, which defines ICP elevations into 3 major pathophysiological subsets: increased cerebral blood volume, masses and edema, and hydrocephalus. (1) Increased cerebral blood volume increases ICP and arises secondary to arterial or venous hypervolemia. Arterial hypervolemia is produced by autoregulated or dysregulated vasodilation, both o...

Patterns of Hysteresis Between Induction and Emergence of Neuroanesthesia Are Present in Spinal and Intracranial Surgeries
Conclusions: Hysteresis was observed between propofol concentrations at LOR and ROR, in both patients presenting for spinal and intracranial surgeries. Manipulation of the brain does not appear to change patterns of hysteresis, suggesting that neural inertia may occur in humans, in a way similar to that found in animal species. These findings justify performing a clinical study in patients using measured propofol concentrations to assess neural inertia. (Source: Journal of Neurosurgical Anesthesiology)
