Neuromonitoring plays an important role in the management of traumatic brain injury. Simultaneous assessment of cerebral hemodynamics, oxygenation, and metabolism allows an individualized approach to patient management in which therapeutic interventions intended to prevent or minimize secondary brain injury are guided by monitored changes in physiologic variables rather than generic thresholds. This narrative review describes various neuromonitoring techniques that can be used to guide the management of patients with traumatic brain injury and examines the latest evidence and expert consensus guidelines for neuromonitoring...

INTRODUCTION: Thyroid and parathyroid surgery (TPTS) is associated with risk of injury to the recurrent laryngeal nerve, superior laryngeal nerve and voice changes. Intraoperative neuromonitoring (IONM), intermittent or continuous, evaluates the functional state of the laryngeal nerves and is being increasingly used. This means that points of consensus on the most controversial aspects are necessary. OBJECTIVE: To develop a support document for guidance on the use of IONM in TPTS...

Coma is an acute failure of neuronal systems governing arousal and awareness and represents a medical emergency. When encountering a comatose patient, the clinician must have an organized approach to detect easily remediable causes, prevent ongoing neurologic injury, and determine a hierarchical plan for diagnostic tests, treatments, and neuromonitoring. Coma was chosen as an Emergency Neurological Life Support protocol because timely medical and surgical interventions can be life-saving, and the initial work-up of such patients is critical to establishing a correct diagnosis...

OBJECTIVE: Laryngeal electromyography (LEMG) of the thyroarytenoid (TA) muscle alone may not be sufficient in all patients to characterize or prove a recurrent laryngeal nerve (RLN) lesion in cases of vocal fold immobility. LEMG of the posterior cricoarytenoid (PCA) muscle may provide additional information. STUDY DESIGN: Retrospective review. METHOD: Between 2008 and 2016, 339 patients in our laryngeal paralysis clinic were examined by transcutaneous needle TA-LEMG and, if tolerated, by PCA-LEMG...

Anesthesia monitoring currently needs a reliable method to evaluate the effects of the anesthetics on its primary target, the brain. This study focuses on investigating the clinical usability of a functional near-infrared spectroscopy (fNIRS)-derived machine learning classifier to perform automated and real-time classification of maintenance and emergence states during sevoflurane anesthesia. For 19 surgical procedures, we examine the entire continuum of the maintenance-transition-emergence phases and evaluate the predictive capability of a support vector machine (SVM) classifier during these phases...

BACKGROUND: Recurrent laryngeal nerve (RLN) palsy is a serious complication of thyroid surgery. During intraoperative neuromonitoring (IONM) of the RLN in thyroid surgery, repeated shifting between surgical instruments and the nerve stimulator is cumbersome and time-consuming. Therefore, we developed a simple detachable magnetic nerve stimulator that may be connected to all metallic surgical instruments. This study aimed to investigate the feasibility and efficacy of this detachable magnetic nerve stimulator for IONM in a porcine model and humans...

Traumatic brain injury (TBI) is a major cause of disability and death globally. Despite significant progress in neuromonitoring and neuroprotection, pharmacological interventions have failed to generate favorable results. We examined the effect of memantine on serum levels of neuron-specific enolase (NSE), a marker of neuronal damage, and the Glasgow Coma Scale (GCS) in patients with moderate TBI. Patients were randomly assigned to the control group (who received standard TBI management) and the treatment group (who, alongside their standard management, received enteral memantine 30 mg twice daily for 7 days)...

Transoral thyroidectomy (TOT) represents reasonably the desirable minimally invasive approach to the gland due to the scarless non-visible incisions, the limited distance between the gland and the access that minimize tissue dissection and respect of the surgical anatomical planes. Patients are routinely selected according to an extensive inclusion criteria: (I) ultrasonographically (US) estimated thyroid diameter not larger than 10 cm; (II) US gland volume ≤45 mL; (III) nodule size ≤50 mm; (IV) a benign tumor, such as a thyroid cyst, single-nodular goiter, or multinodular goiter; (V) follicular neoplasm; (VI) papillary microcarcinoma without lymph node metastasis...

Reoperations of the thyroid gland are challenging to any surgeon. Such procedures are technically difficult and involve higher risk of complications than primary procedures. Recurrent laryngeal nerve (RLN) palsy is one of such complications The aim of the study was to evaluate the effectiveness of intraoperative neuromonitoring (IONM) in preventing RLN palsy during recurrent goiter operations. MATERIAL AND METHODS: We retrospectively analyzed the results of thyroid reoperation performed at the Department of Endocrine, General and Vascular Surgery of Medical University of Lodz in the period from January 2014 to June 2016...

BACKGROUND AND PURPOSE: The pathogenesis of poor functional outcome after aneurysmal subarachnoid hemorrhage (aSAH) is not fully understood. Microcirculatory dysfunction, which can be indirectly measured by CT perfusion (CTP), is assumed to play a central role. We evaluated the predictive value of early changes in microcirculation for secondary critical perfusion changes. MATERIALS AND METHODS: Out of 351 consecutive aSAH patients, 166 patients with ≥1 CTP within 72h of ictus (early CTP) and ≥3 CTPs in total were included in the retrospective analysis (53...

Functional near-infrared spectroscopy (fNIRS) is an increasingly common neuromonitoring technique used to observe evoked haemodynamic changes in the brain in response to a stimulus. The measurement is typically in terms of concentration changes of oxy- (∆HbO2) and deoxy- (∆HHb) haemoglobin. However, noise from systemic fluctuations in the concentration of these chromophores can contaminate stimulus-evoked haemodynamic responses, leading to misinterpretation of results. Short-separation channels can be used to regress out extracerebral haemodynamics to better reveal cerebral changes, significantly improving the reliability of fNIRS...

PURPOSE OF REVIEW: The current article revises the recent evidence on ICU admission criteria and postoperative neuromonitoring for patients undergoing elective craniotomy. RECENT FINDINGS: Only a small proportion of elective postoperative neurosurgical patients require specific medical interventions and invasive monitoring. Among these, patients undergoing elective craniotomy are frequently admitted to neuro-ICU, specialist postanaesthesia care units or intermediate-level care unit in the postoperative period...
