Electrocautery and Spinal Cord damage- loss of motor activities..!

Nerve damages or spinal cord damage during brain and spine surgical procedures depends upon various myraids of factors, one of them is mechanical. However, how many of you even thought of an electrocautery can produce spinal cord damage resulting EMGs and motor activity loss?. This report published in an porcine model discusses a case. I have not read a human case yet, but it is a real possibility, it can happen during surgery.  If anyone knows a human case or clinical scenario's, please post a comment below.

Spinal cord injury from electrocautery: observations in a porcine model using electromyography and motor evoked potentials. Stanley A. Skinner, et al  Journal of Clinical Monitoring and Computing November 2012

Abstract

We have previously investigated electromyographic (EMG) and transcranial motor evoked potential (MEP) abnormalities after mechanical spinal cord injury. We now report thermally generated porcine spinal cord injury, characterized by spinal cord generated hindlimb EMG injury activity and spinal cord motor conduction block (MEP loss). Electrocautery (EC) was delivered to thoracic level dural root sleeves within 6–8 mm of the spinal cord (n = 6). Temperature recordings were made near the spinal cord. EMG and MEP were recorded by multiple gluteobiceps intramuscular electrodes before, during, and after EC. Duration of EC was titrated to an end-point of spinal motor conduction block (MEP loss). In 5/6 roots, ipsilateral EMG injury activity was induced by EC. In 4/5 roots, EMG injury activity was identified before MEP loss. In all roots, a minimum of 20 s EC and a temperature maximum of at least 57 °C at the dural root sleeve were required to induce MEP loss. Unexpectedly, conduction block was preceded by an enhanced MEP in 4/6 trials. EMG injury activity, preceding MEP loss, can be seen during near spinal cord EC. Depolarization and facilitation of lumbar motor neurons by thermally excited descending spinal tracts likely explains both hindlimb EMG and an enhanced MEP signal (seen before conduction block) respectively. A thermal mechanism may play a role in some unexplained MEP losses during intraoperative monitoring. EMG recordings might help to detect abnormal discharges and forewarn the monitorist during both mechanical and thermal injury to the spinal cord.

Brain Awarness Week- Spread the Word..!

Best Wishes to Brain Awareness Week Program, the people behind and to Sharp Brains, Thanks, DrMuni Muni,      How will you be cel­e­brat­ing Brain Aware­ness Week next week (March 11th-17th , 2013)? Here's a sug­ges­tion: you can start watching, at a spe­cial 95% pric­ing dis­count, more than 25 hours of exclu­sive pre­sen­ta­tions from over 40 lead­ing minds as they discuss the latest on applied neu­ro­plas­tic­ity and brain health. These pre­sen­ta­tions, which took place dur­ing the 2012 Sharp­Brains Vir­tual Sum­mit, shed light on some of the most impor­tant ques­tions about the cur­rent and future state of brain health and wellness: How can the health indus­try bet­ter incor­po­rate the body's most vital organ -- the brain? How are con­sumer beliefs and behav­iors towards brain health and brain train­ing evolving? Which pro­fes­sional groups are ide­ally posi­tioned to become "brain fit­ness coaches"? How can neu­ro­science inform spe­cial education? How can Big Data and global inter­net access trans­form brain health practices?   -> You can ORDER A $15 PASS NOW (reg­u­lar price is $295).

App for remote Neurominotoring (IONM)?

 APP for biking track, app for walking, app for finding what song it is and now an App for remote neuromontioring?, interesting!.

inomed Remote Viewer by Netop Supports Neuromonitoring,  February 26, 2013New app enables physicians and clinical staff to remotely monitor real-time data from intraoperative neurophysiological monitoring (IONM) devices via an iPad.

COPENHAGEN – inomed, a leading medical technology provider based in Germany, has announced the availability of an app that enables hospital staff to remotely monitor the signals of a patient’s intraoperative nerve activity during surgery. The app, Remote Viewer, was developed for inomed by Netop and is based on their remote access application, Netop Remote Control Mobile for iOS. With inomed Remote Viewer, doctors and hospital personnel can securely and remotely track neuromonitoring signals - recorded on an inomed IONM device - in real-time.

“We’re pleased to be working with inomed on the Remote Viewer,” said Kurt Bager, CEO, Netop. “This is not only an example of how our remote access solutions can be leveraged across industry verticals to serve the evoling needs of our customers and partners, but also how our solutions perform in critical environments where reliability is an absolute necessity.”

With Netop’s remote access software solution now preinstalled on all inomed neuromonitoring devices, the app allows inomed to expand its product offerings and provide its customers with additional service levels. To activate the functionality users will need to purchase an inomed license for the company’s neuromonitoring device, but the Remote Viewer app is free and available for iOS devices at the App Store.

Vascular Complications During Thoracic Pedicle Screw Placement: What?. Is this even Possible, yes!.

Surgery insight: During surgical performance or surgical procedures and providing patient care, there is nothing like oh you mean that?, well that is very simple or take for granted in a casual way, one must show at most attention and care in every small to big steps, so do the neuromonitoring and anesthesia professionals, you can be of great help to surgeon when you detect changes or unusual activity that can get surgeons attention right away. Ofcourse for surgeons, there is no room for error but absolutely there is no room for Oh I have done 1000s of surgery, pricking a nerve or artery during my pedicle screw insertion is not going to happen, oh well, it did. The following paper describes a case and death of a patient two weeks after the surgery, so be diligent.

While reading this article :Thoracic pedicle screw placement: Free-hand technique  by Yongjung J. Kim, Lawrence G. Lenke regarding Scoliosis and thoraci pedicle screw placement, I came across the two back reference that startled me, an important and interesting reference about how vascular complications can occur by careless pedicle screw placement?..

What is O-Arm, is the X-Ray imaging finally getting a Facelift in tech?

Interesting tech developments seems to be happening in X-Ray imaging, came across news about O-Arm today and also noticed the fluoroscopic ultra-imaging developments and check those below, as well as the link to Hologic?...This area or technology can be quite useful to surgeons and hospitals, this is something they better look at for efficient surgical procedures and precision detection.

Here is the O-Arm, will this help surgeon view different angles, depth and positioning of pedicle screws and so on?.

Have you seen the O-arm™ Imaging System before? We haven’t. Until today, that is. We learned about it this morning when a company’s rep left O-arm™ brochures (and no food) in our physicians’ lounge. The device byBreakaway Imaging, LLC, of Littleton, MA, was FDA-cleared last year and is now distributed by Medtronic.
So here’s the scoop about the device that has a robotics-assisted positioning system:
