Total Intravenous Anesthesia for Intraoperative Neurophysiological Monitoring in a Child With Diastematomyelia: A Case Report.
Cureus
December 2024
Radiology, SRM Medical College Hospital and Research Center, Chennai, IND.
Intraoperative neurophysiological monitoring (IONM) has achieved popularity because it facilitates monitoring of the functional integrity of neural structures under general anesthesia. It aids in the early detection of injury and minimizes postoperative neurologic deficit or neurologic morbidity from surgical manipulations of various neurologic structures. The patient mentioned in this case report presented with lower limb radiculopathy and was diagnosed with diastematomyelia Type II, and she was planned for surgical intervention under general anesthesia.

Optically pumped magnetometer-based magnetoencephalography (OPM-MEG) is an novel non-invasive functional imaging technique that features more flexible sensor configurations and wearability; however, this also increases the requirement for environmental noise suppression. Subspace projection algorithms are widely used in MEG to suppress noise. However, in OPM-MEG systems with a limited number of channels, subspace projection methods that rely on spatial oversampling exhibit reduced performance.

Sony Computer Science Laboratories Inc., Tokyo, Japan.
Dexterous motor skills, like those needed for playing musical instruments and sports, require the somatosensory system to accurately and rapidly process somatosensory information from multiple body parts. This is challenging due to the convergence of afferent inputs from different body parts into a single neuron and the overlapping representation of neighboring body parts in the somatosensory cortices. How do trained individuals, such as pianists and athletes, manage this? Here, a series of five experiments with pianists and nonmusicians (female and male) shows that pianists have enhanced inhibitory function in the somatosensory system, which isolates the processing of somatosensory afferent inputs from each finger.

Resuscitation

Department of Critical Care Medicine, Hospital for Sick Children, Department of Paediatrics, University of Toronto, Neurosciences and Mental Health Program, Research Institute Toronto, ON, Canada.
Aim: To evaluate the ability of blood-biomarkers, clinical examination, electrophysiology, or neuroimaging, assessed within 14 days from return of circulation to predict good neurological outcome in children following out- or in-hospital cardiac arrest.
Methods: Medline, EMBASE and Cochrane Trials databases were searched (2010-2023). Sensitivity and false positive rates (FPR) for good neurological outcome (defined as either 'no, mild, moderate disability or minimal change from baseline') in paediatric survivors were calculated for each predictor.
The Influence of Anesthesia on Neuromonitoring During Scoliosis Surgery: A Systematic Review.
NeuroSci
December 2024
Department of Palliative Medicine, Poznan University of Medical Sciences, 61-701 Poznań, Poland.
Article Synopsis
- Intraoperative neuromonitoring (IONM) is essential for ensuring patient safety during scoliosis surgery by monitoring spinal cord and nerve function through motor-evoked potentials (MEPs), with anesthesia type affecting the accuracy of these signals.
- A systematic review was carried out, analyzing studies from major medical databases, which evaluated the impact of various anesthetic techniques on neuromonitoring during scoliosis procedures, narrowing down from 998 articles to 45 for detailed analysis.
- The findings suggest that the Erector Spinae Plane Block (ESPB) offers significant advantages over traditional spinal and epidural anesthesia by improving neuromonitoring accuracy, reducing complications, and providing effective pain management, leading to better patient outcomes.
