Spinal cord tumor removal & Neuromonitoring

Spinal cord tumor resection can pose serious risks of
surgical
induced sensory or motor deficits, intraoperative neuromonitoring
of
combined sensory and motor pathways can be useful to prevent potential
damages. Here are some collective articles related to spinal cord tumor resection.

Spinal Cord integerity risk & Tibial single Trial SSEP?

Single trial Tibial Somatosensory SSEP along with H-reflex can be used to monitor the spinal cord integerity and function during surgical procedures that put the cord in risk. The following article
describes how this combination of a single trial SSEP can be
useful?.

When spinal cord functional integrity is at risk during surgery, intraoperative neuromonitoring is recommended.

Tibial Single Trial Somatosensory Evoked Potentials (SEPs) and H-reflex are here used in a combined neuromonitoring method: both signals monitor the spinal cord status, though involving different nervous pathways.
However, SEPs express a trial-to-trial variability that is difficult to track because of the intrinsic low signal-to-noise ratio. For this reason single trial techniques are needed to extract SEPs from the background EEG.

4th and 5th Cervical Laminae-Acute Hemiparesis?

This interesting article published in the "Journal of Bone and Joint Surgery" describes spinal cord injuries at the C4-C5 level caused by a serious head-on vehicle collision in a 18 year old teenager. The accident resulted in invagination of C4-C5 laminae into the spinal canal and also fractures leading to hemiparesis?. Surgical intervention of laminectomy, fusion and stabilization with instrumentation resulted in recovery from right sided weakness and recovery of full neurological functions.

Traumatic invagination of the fourth and fifth cervical laminae with acute hemiparesis
U. R. Hähnle, L. Nainkin
From the University of the Witwatersrand, Johannesburg, South Africa

The patient was initially treated by skeletal traction (3 kg) applied using
Crutchfield tongs. As the neurological deficit did not recover
during the following week operation was undertaken.
Through a posterior approach, exposing the laminae and
lateral masses from C3 to C6, the invagination of the right
laminae of the C4 and the C5 vertebrae was confirmed. All
other posterior elements such as the facet joints, ligamentum
flavum, interspinous ligaments and spinous processes
were intact. The fracture at C2 was not exposed.
Reduction of the invaginated laminae was achieved by
gentle traction on the spinous processes. Mild flexion of the
neck helped to maintain the reduction. As the neck was
extended there was a tendency for the laminae to reinvaginate.
Transverse wiring of the two involved spinous processes
was undertaken with tension towards the left-sided
lateral masses to maintain the position of the reduced
laminae.
Adequate decompression was confirmed on a postoperative
CT scan (Figs 3a and 3b).

How to Calculate Frequency, Duration & Amplitude in EEG?

Bill Byrum writes about how to analyse and evaluate EEG inorder to calculate the frequency, duration etc., in the following article that appeared in the latest ASET newsletter.

Calculating Frequency, Duration, Amplitude, and Voltage Using a Legend
By Bill Byrum, MBA, R. EEG/EP T., CNIM

In this article I want to review with you
how simple it is to use a Legend. You will
need a measurement ruler graduated into
one mm segments. It would also be handy
to have a calculator that can be set to divide
to 3 decimal places. If you perform division
by hand, please be sure to carry the results
to 3 decimal places when calculating
waveform duration.
I strongly recommend whenever you
are doing calculation utilizing a Legend
that you use a referential montage and the
reference is not contaminated with EEG
activity. This is because in a bipolar
montage the waveforms are the result of
two inputs active with EEG activity. The
same can be said of a referential montage if
the reference is contaminated. For complete article, click the linked title?.

NEUROMONITORING COMPANIES IN AMERICA: How Many? & Who are they?

  • Neuromonitoring1 ......is the only place on the internet or offline on any books where you will find list of companies that provide Neuromonitoring in America, it is not clear at this moment how many countries health care system applies this approach (there is no data on it, but I am sure there are only handful of nations like USA, Canada, UK, Sweden, Singapore so far known to employ or have companies doing this service, among them the most widely established neuromonitoring practices occur in US.

  • This list is by far the comprehensive, though it does not reflect one hundred percent of companies in US but certainly most of them with a webaddress and well known names are listed here.
A list of all these neuromonitoring companies are documented at the bottom of this blog under separate topic: Neuromonitoring Companies!!.
You will be able to get more details of those companies such as name brand, directors, office staff, company goals, operating areas and schedules etc., along with the link to each company at the very bottom of this blog under title Neuromonitoring Companies and Centers.
Two of the latest addition are Synapse neuromonitoring and Argos Neuromonitoring, the list will be updated periodically.

The rate of permanent recurrent laryngeal nerve paresis after thyroidectomy for instance comes up to 9%. Almost 40% of patients with acute dissection of the thoracoabdominal aorta suffer from paraplegia after aneurysm repair. Despite a wake-up test 0.7 to 1.6% are paraplegic after corrective procedures for scoliosis. After cardiac procedures with extracorporal circulation there is a 1 to 3% incidence of severe neurologic deficits and an incidence of cognitive deficits running up to 80%. Finally the stroke rate after carotid endarterectomy comes to 7% in well documented series [2, 3 , 4 ,5,7].

Cardiovascular Surgery (like Cardiopulmanory bypass-CPB) & Neuromonitoring!

The following article demonstrates that neuromonitoring is very useful in cardiovascular surgeries, especially in patients with cerebrovascular diseases.

Intraoperative neuromonitoring in cardiac surgical patients with severe cerebrovascular disease
Alexander Kulik, MD, Rosendo A. Rodriguez, MD PhD, Howard J. Nathan, MD and Marc Ruel, MD MPH
University of Ottawa, Ottawa, Canada, E-mail: akulik@ottawaheart.ca

To the Editor:
Patients with severe cerebrovascular disease are at a high risk of neurologic complications during cardiac surgery, as a result of cerebral embolization or hypoperfusion during cardiopulmonary bypass (CPB). Intraoperative neuromonitoring, including transcranial Doppler ultrasound (TCD) and electroencephalography (EEG), may be particularly useful in patients with cerebrovascular disease.1 We hereby present two cases that illustrate the use of intraoperative neuromonitoring during cardiac surgery in patients with severe cerebrovascular disease.

Submitted 7 June 2007; accepted in final form 6 October 2007

Multichannel techniques were used to assess the frequency specificity of activation in the central nucleus of the inferior colliculus (CIC) produced by electrical stimulation of localized regions within the ventral cochlear nucleus (VCN). Data were recorded in response to pure tones from 141 and 193 multiunit clusters in the rat VCN and the CIC, respectively. Of 141 VCN sites, 126 were individually stimulated while recording responses in the CIC.....................

The above article published in the latest issue of "European Journal of Neuroscience, discusses issues on hearing loss and possible involvement of trigeminal nerve?

Abstract:
Hearing loss due to VIII nerve damage or loss of synaptic connectivity of VIII nerve in the cochlear nucleus is a common degenerative changes observed in models of noise damage, similar degeneration of terminals also reported in cases of hearing loss in humans. However, the above article discusses the possiblity of the involement of "Trigeminal Nerve" as a compensatory response to the loss of VIII nerve connections following noise induced hearing loss in animal models. How much of this compensatory response is due to hearing loss or changes in VIII nerve connectivity is not clear, however, it is interesting to note how the neighbouring cranial nerve respond.

The authors observe the following changes in responses to trigeminal stimulation: The guinea pigs with noise-induced hearing loss had significantly lower thresholds, shorter latencies and durations, and increased amplitudes of response to trigeminal stimulation than normal animals. Noise-damaged animals also showed a greater proportion of inhibitory and a smaller proportion of excitatory responses compared with normal. Authors also argue that there is increased inhibitory responses and increased activity of somatosensory response, prompting them to conclude a role of somatosensory inputs in noise induced hearing loss? is yet to be clarified by extensive studies!.

Here is a Science Daily which is jumbing into conclusions of the following kind?.
'Ringing In The Ears' May Be Caused By Overactive Nerves, Acupuncture May Help, Study Suggests

Scoliosis & More

The following article on Scoliosis provide a comprehensive look at what is scoliosis and related surgical interventions. Though, hard to explain the causes for scolisosis, efforts to understand this disease provided us more knowledge. Intraoperative neuromonitoring is extensively used in scoliosis correction surgical procedures.

Scoliosis and Proprioception
Robert Schleip
Published in Rolf Lines, Vol. 28, No.4 (Fall 2000)
Most types of scoliosis are classified as ‘idiopathic scoliosis’ which means that the reasons for this type of rotational deformity of the spine are yet unknown. Nevertheless there are all kinds of assumptions, beliefs and anectdotal reports available in the alternative health community concerning the main causes and driving factors.........................


Central Nervous System Processing in Idiopathic Scoliosis
By Jerry Larson, M.A.
Diplomate, American Board of Neurophysiological Monitoring

"The clinical manifestations of idiopathic scoliosis are well known, yet its causes remain unclear. Several factors have been proposed, including abnormal structural elements of the spine, dysfunctional spinal musculature, genetic factors, alterations of collagen metabolism, and abnormalities of the central nervous system. The most promising investigations appear to implicate the central nervous system, especially those areas involved with postural equilibrium. Spinal cord reflexes play an integral role in the maintenance of posture. These complex polysynaptic segmental reflexes are regulated by a variety of descending suprasegmental systems, by peripheral afferent impulses and within the spinal ....................

David J. Anschel, M.D.
Contributing Editor of MedCompare,

David J. Anschel writes about the developments in "Itraoperative Neurophysiological Monitoring and its medical usage:

IONM has become the gold standard for ensuring patient safety while undergoing operations which place the central or peripheral nervous system at risk. Technological advancements within the last few years have allowed monitoring techniques to evolve. The above robust systems are representative of the best that modern medicine has to offer. Allowing neurologists and surgeons to work together to provide better patient outcomes during more complicated procedures in close proximity to vital neurological tissues.

SAFETY IN THE OR: By Association of Peri Operative Registered Nurses, ALAMEDA county #0501

The Peri-Operative registered Nurses of Alameda country chapter #0501 has this fabulous informative site about what and what not to do in the OR, OR safety and policies. Though it was written for vendors (the suppliers and tech's), it is a great informative sources for anyone in the OR, the neurophysiolgosits and neuromonitoring crew's may find this very useful and informative, I did so. Thanks to the AORN for such a useful resources of knowledge in OR.
Vendor Policy - AORN of Alameda County
VendorsIn The Operating Room

Following completion of the self-directed learning module, the Vendor will be able to:
1. Classify various areas within the surgical suite, (e.g., restricted, semirestricted and unrestricted).
2. Describe proper surgical attire.
3. Describe proper handwashing technique and its importance.
4. Compare and contrast the communicability of HIV, HAV and HBV.
5. Describe steps to follow during a fire in the operating room.
6. Describe basic procedure during electrical outage.
7. Name plans for prevention of tuberculosis exposure.
Aseptic Technique
Aseptic technique is essential in all operating rooms. It should be considered the "law of the land". If breached, the consequences can be far-reaching and potentially devastating to the patient and the reputation of the hospital involved. The patient is particularly at risk for invasion of exogenous bacterial infections because the most significant protective barrier (the skin) is interrupted during surgery. Therefore, this is one of the most important sections in this module.

Remifentenil Reduces Patient Movement during Neurosurgery?

Doctors Guide is a very informative website on various fields of medicine and related subjects, mainly aimed to serve the doctors and information seekers in the allied health field and general public. http://www.docguide.com. It is freely accessible, if you want to personalize, you have to register and it is free.

The following article is relevant and interesting to neurophysiologists who do intraoperative neuromonitoring, also for anesthesiologists and the neurosurgeons who are concerned about patient movement during surgical procedure. In the recent annual meeting of the "American Soceity of Anesthesiologists the following work on Remifentanil was presented. Arushi Sinha, PhD writes about a presentation on how remifentanil can reduce patient movement during neurosurgery.


New Approaches for Reducing Patient Movement During Neurosurgery:
Presented at ASA
By Arushi Sinha, PhDSAN FRANCISO, CA -- October 23, 2007 --
Remifentanil reduces the risk of movement in the absence of muscle relaxants among patients undergoing elective craniotomy, researchers reported here at the Annual Meeting of the American Society of Anesthesiologists (ASA).In the case of neuroanaesthesia surgeries, muscle relaxants may not be indicated, particularly if intraoperative monitoring of motor evoked potentials or electromyography are involved. Alternative agents, such as remifentanil and propofol, may be used in such settings according to recent research.Marco Maurtua, MD, Assistant Professor, Department of Anesthesiology, Cleveland Clinic Foundation, Cleveland, Ohio, United States, and his colleagues designed a study to characterise the role of remifentanil in reducing movement associated with neurosurgical stimuli and to examine the incidence of bradycardia and hypotension in elective craniotomy patients.

Somatosensory and Motor Evoked Potentials during Sevoflurane and Propofol Anesthesia

Michael S. Kincaid, M.D., Michael J. Souter, M.D., Patrick D. Bryan, Mark Klein, Arthur M. Lam, M.D.Anesthesiology, University of Washington, Seattle, Washington

Background and Purpose: Transcranial electrical motor evoked potentials (MEP) have joined somatosensory evoked potentials (SSEP) as an important aspect of neurophysiologic monitoring during both intracranial and spine surgery. General anesthesia is known to diminish the quality of signals with SSEP, decreasing amplitude and increasing latency, with volatile anesthesia having a greater effect than intravenous anesthesia. There is little quantitative information on the comparative effect of volatile and intravenous anesthetics on MEP signal quality, however. The purpose of this study is to describe the effects of propofol and sevoflurane on SSEP and MEP in patients undergoing both spine and neurosurgical procedures.

You do Spine surgery and Do not monitor nerves..Why?



Neuro monitoring (a.k.a.: Neurophysiologic Intraoperative Monitoring) may be one of the most exciting and important €œold€ innovations to come into spine and neuro surgery in decades.

Think of it, what surgeon would dare operate without blood gas monitoring? Or blood pressure monitoring?
So why operate without nerve monitoring?

We recently talked with Debra Zacharko, who teaches neuro monitoring for NeuroMatrix in Atlanta. She described a case in which one of her clients scheduled a straightforward laminectomy and declined to use neuro monitoring. €œSo, I told him that I'€™d perform the monitoring for free,€ said Zacharko, €œand when I showed him the wave form tapes

he was amazed to see how much nerve irritation there is even in a simple laminectomy.€

Surgical Technologist’s Guide to Brain Anatomy

Despite all the research and studies we have, we still do not know all there is to know about the human brain. While there is still much to learn, we do know that the nervous system has many divisions working in conjunction with one another. This article will focus largely on the central nervous system, related neurological pathways and neurolinguistics, with an emphasis on the brain its anatomy. You can find a basic introduction to the peripheral nervous system at Dartmouth University’s Neuroscience department. The central nervous system directs the functions of all tissues of the body and can be seen through many different techniques, including pictures, MRI imaging, cross-sectioning, and labeled diagrams. Below you’ll find a collection of resources categorized by images of the brain, guides to neurolinguistics, studies on neurological pathways and further reading and images about specific parts of the central nervous system, categorized by the forebrain, midbrain, and hindbrain. Included at the very end are links to journals, research and organizations related to brain anatomy.
