Chronic or neuropathic trigeminal facial pain can be challenging to treat. Neurosurgical procedures should be applied when conservative treatment fails. Neuromodulation techniques for chronic facial pain include deep brain stimulation and motor cortex stimulation, which are complex to perform. Subcutaneous nerve field stimulation is certified for chronic back pain and is the least invasive form of neuromodulation. We applied this technique to treat chronic and neuropathic trigeminal pain as an individual therapy concept...

In the early days of modern neurological surgery, the inconveniences and potential dangers of general anesthesia by chloroform and ether using the so-called "open-drop technique" led to the quest for alternative methods of anesthesia. This became all the more necessary, since patient positioning and the surgical arrangements often hindered the use of a drop bottle. One approach to solve this problem was intra-rectal ether application. The present article aims to shed light on this original, less well-known anesthesia technique in the neurosurgical field...

REVIEW

For a long time, the right hemisphere (RH) was considered as "non-dominant", especially in right-handers. In neurosurgical practice, this dogma resulted in the selection of awake procedure with language mapping only for lesions of the left "dominant" hemisphere. Conversely, surgery under general anesthesia (possibly with motor mapping) was usually proposed for right lesions. However, when objective neuropsychological assessments were performed, they frequently revealed cognitive and behavioral deficits following brain surgery, even in the RH...

BACKGROUND: Endovascular neurosurgery is known to be associated with potentially serious perioperative complications that can impact the course and outcome of anesthesia. We present here our institutional experience in the anesthetic management of various endovascular neurosurgical procedures and their related complications over a 10-year period. METHODS: Data was obtained in 240 patients pertaining to their preoperative status, details of anesthesia and surgery, perioperative course and surgery-related complications...

BACKGROUND: Traditionally, mechanical ventilation is achieved via active lung inflation during inspiration and passive lung emptying during expiration. By contrast, the novel FLEX (FLow-controlled EXpiration) ventilator mode actively decreases the rate of lung emptying. We investigated whether FLEX can be used during intraoperative mechanical ventilation of lung-healthy patients. METHODS: In 30 adult patients scheduled for neurosurgical procedures, we studied respiratory system mechanics, regional ventilation, oxygenation, and hemodynamics during ventilation with and without FLEX at positive end-expiratory pressure (PEEP) of 5 and 7 cm H2O...

Hironobu Hayashi, Masahiko Kawaguchi
In neurosurgical procedures that may cause visual impairment in the intraoperative period, the monitoring of flash visual evoked potential (VEP) is clinically used to evaluate visual function. Patients are unconscious during surgery under general anesthesia, making flash VEP monitoring useful as it can objectively evaluate visual function. The flash stimulus input to the retina is transmitted to the optic nerve, optic chiasm, optic tract, lateral geniculate body, optic radiation (geniculocalcarine tract), and visual cortical area, and the VEP waveform is recorded from the occipital region...

OBJECTIVE: Stereotactic biopsy is an everyday procedure implemented in numerous neurosurgical departments. The procedure is performed in order to obtain tumor tissue of unclear diagnosis. Going in hand with low complication rates and high diagnostic yield, stereotactic biopsies can be performed in adults and children likewise for histopathological evaluation of lesions in eloquent localizations. Little is known, however, whether aged patients do benefit from stereotactic biopsy or rather the therapy that is derived from histopathological results...

Neuroendoscopy has established itself as a routine neurosurgical procedure in pediatric population. To have an uneventful smooth perioperative course, it is important for anesthesiologist to know about the key steps, possible complications, and specific anesthetic requirements. Among neuroendoscopies, endoscopic third ventriculostomy is the commonly performed one.

The functional organization of human auditory cortex remains incompletely characterized. While the posteromedial two thirds of Heschl's gyrus (HG) is generally considered to be part of core auditory cortex, additional subdivisions of HG remain speculative. To further delineate the hierarchical organization of human auditory cortex, we investigated regional heterogeneity in the modulation of auditory cortical responses under varying depths of anesthesia induced by propofol. Non-invasive studies have shown that propofol differentially affects auditory cortical activity, with a greater impact on non-core areas...

Background and Study Aims Surgical treatment for acute subdural hematomas (ASDHs) in elderly patients is still considered unsatisfactory. Series focusing on the use of conventional craniotomy or decompressive craniectomy in such patients report discouraging results. Glasgow Coma Scale (GCS) score at admission seems to be crucial in the decision-making process. Deteriorating patients with a GCS score between 9 and 11 are those who would benefit most from the surgical treatment. Unfortunately, elderly patients often present other comorbidities that greatly increase the risk of severe complications after major neurosurgical procedures under general anesthesia...

BACKGROUND: Arnold-Chiari malformation Type 1 (ACM-1) in parturients is a topic of ongoing discussion between obstetricians and anesthesiologists. The primary unanswered question remains; How should the anesthesia provider proceed with labor analgesia and anesthesia for cesarean section when confronted with an advanced, asymptomatic, or minimally symptomatic case of ACM-1 during labor? CASE DESCRIPTION: A 24-year-old, ASA II, G1P0 full-term parturient presented to Labor and Delivery for vaginal delivery...

BACKGROUND: Induced hypotension (IH) had been used for decades in neurosurgery to reduce the risk for intraoperative blood loss and decrease blood replacement. More recently, this method fell out of favor because of concerns for cerebral and other end-organ ischemia and worse treatment outcomes. Other contributing factors to the decline in its popularity include improvements in microsurgical technique, widespread use of endovascular procedures, and advances in blood conservation and transfusion protocols...

Critical care medicine came into sharp focus in the second part of the 20th century. The care of acutely ill neurologic patients in the USA may have originated in postoperative neurosurgical units, but for many years patients with neurocritical illness were admitted to intensive care units next to patients with general medical or surgical conditions. Neurologists may have had their first exposure to the complexity of neurocritical care during the poliomyelitis epidemics, but few were interested. Much later, the development of neurocritical care as a legitimate subspecialty was possible as a result of a new cadre of neurologists, with support by departments of neurosurgery and anesthesia, who appreciated their added knowledge and expertise in care of acute neurologic illness...

Although some studies have examined the efficacy and safety of remifentanil in patients undergoing neurosurgical procedures, none has examined its safety in transsphenoidal operations specifically. In this study, all transsphenoidal operations performed by a single author from 2008 to 2015 were retrospectively reviewed to evaluate the safety of remifentanil in a consecutive series of patients. During the study period, 540 transsphenoidal operations were identified. Of these, 443 (82.0%) patients received remifentanil intra-operatively; 97 (18...

OBJECTIVE: To describe the anesthetic considerations in patients undergoing laser interstitial thermal therapy (LITT) for neurosurgical procedures. BACKGROUND: LITT for neurosurgical procedures is being increasingly used in a variety of central nervous system diseases. Several studies have demonstrated promising results including a shorter hospital stay. Given the rising trend for the use of LITT, anesthesiologists need to be familiar with the anesthetic considerations to provide care for patients undergoing these types of procedures...

BACKGROUND: Studies have suggested that both the degree and the duration of hyperglycemia are independent risk factors for adverse outcome both in pediatric anesthesia and in critically ill children. In a recent paper, we combined intraoperative glycemic variations and length of surgery creating a metabolic glucose-related stress index called "Glycemic Stress Index" (GSI). AIM: To validate GSI for predicting PICU stay in a population of children undergoing different major neurosurgical procedures...
