NIM 2.0 NERVE MONITORS

NIM 2.0 Nerve Monitors

Indications

This device is intended for use in surgical procedures for patient-connected intraoperative nerve monitoring, ie, assisting the surgeon in locating and mapping motor nerves through the use of electromyographic (EMG) signals and electrical stimulus of nerves. This device is indicated for locating and identifying cranial and peripheral motor nerves during surgery.

Contraindications

The use of paralyzing anesthetic agents will significantly reduce, if not completely eliminate, EMG responses to direct or passive nerve stimulation. Whenever nerve paralysis is suspected, consult an anesthesiologist.

Warnings

The NIM-Neuro™ 2.0 does not prevent the surgical severing of nerves. If monitoring is compromised, the surgical practitioner must rely on alternate methods, or surgical skills, experience, and anatomical knowledge to prevent damage to nerves.

To avoid patient burns:

W2a	Do not activate electrosurgical Instrument while the stimulator is in contact with tissue.
W2b	Do not leave stimulating electrodes or probes in surgical field.
W2c	Do not store stimulating electrodes or probes in electrosurgical Instrument holder.
W2d	Do not allow a second surgeon (ie, fat harvesting) to use electrosurgical instrument while stimulator is in use.
W2e	Special operator attention may be required for stimulus currents exceeding 2 mA RMS/cm2. The RMS value of current is generally lower than the stimulator current setting in mA. To calculate RMS current, waveform morphology, pulse width, repetition rate, and the stimulator current delivered must be considered.

While Muting is activated, auditory and visual monitoring are disabled.

To avoid false negative responses, verify stimulator current setting is high enough, and verify stimulus delivery by tone, voice, or display. Low stimulator current may cause a false negative response.

High stimulator current may cause involuntary patient movement resulting in patient injury.

High stimulator current activating of the fifth cranial nerve or Mastication muscles may cause tongue lacerations.

False negative responses (failure to locate nerve) may result from:

W7a	Shorted EMG electrode or cabling (conductive parts of applied needle electrodes or cables contacting each other).
W7b	Patient Interface fuse blown (32 mA, 250V. Xomed Part No.: 8250615).
W7c	Patient Interface defective.
W7d	Inadequate stimulus current.
W7e	Inadequate current for stimulation of nerve through hardware, such as stimulus dissection instruments, may vary based on the physical size, shape characteristics, and design of the hardware and proximity to the nerve.
W7f	Neuromuscular fatigue from prolonged or repeated exposure to electrical stimuli.
W7g	Inadvertent simultaneous current delivery from both Stimulator (Patient Interface) probe outputs. This may result in current shunting, division between the stimulator probes.
W7h	Shorted internal amplifier (characterized by baseline activity of < 3 μV p-p).

Do not power-on the NIM-Neuro 2.0 when the stimulator is in the surgical field.

To avoid eye injury during electrode placement, the electrode needles should be directed away from the globe and adequately secured with tape.

W10

To avoid the risk of fire or explosion, do not use the NIM-Neuro 2.0 in the presence of flammable anesthetics and/or oxygen rich environments.

W11

To avoid electrical shock, do not attach unapproved components or accessories to the NIM.

W12

To avoid the risk of infection while using the NIM-Neuro 2.0 touchscreen stylus, the user must maintain good sterility practices.

W13

Electrocardiogram monitoring artifacts may be caused by NIM-Neuro 2.0 stimulus current delivery or EMG electrode impedance monitoring.

W14

Direct stimulator contact may disrupt the operation of active implanted devices.

W15

While stimulating, it is recommended to use only approved EMG monitor(s) equipped with active audio and/or visual current delivered feedback systems to ensure delivery of current to intended tissues.

W16

Proper handling, insertion, and placement of electrodes and probes is critical for safe and accurate EMG monitoring:

W16a	Improperly placed or bent needles increase the risk of needle breaking off in the patient.
W16b	Do not attempt to straighten bent needles because this may cause stress and weaken device, causing needle to break off in patient.
W16c	Extreme care must be taken when handling instruments with sharp points or edges.

W17

The surgical practitioner must choose the appropriate size electrodes and probes based on the procedure to be performed and the stimulating current necessary for the application.

W18

Avoid trans-thoracic stimulation; when possible, maintain anode and cathode stimulating sites in close proximity.

W19

Reuse of single use electrodes and probes increase the risk of infection and may cause degraded or ineffective monitoring.

Precautions

Special care must be exercised to distinguish between the high-pitched beep of the Event Tones (EMG activity over threshold), and the Stimulus Warble Tone (indicates the set current is being delivered).

When the “Bleedle Alarm” (BLEE-dle-DEET) sounds, the cause must be identified and eliminated immediately.

To avoid loud, extraneous monitoring noise during electrosurgical unit activation, ensure the Muting Probe is properly attached to the active electrosurgical lead.

Inadequate stimulus current flow may be caused by non-flush contact between the stimulating electrode or probe and the nerve, inadequate stimulator probe electrical contact surface area, or high impedance.

Inability to deliver stimulus current flow may be caused by:

P5a	Stimulator return electrode not connected, or other incomplete electrical connection between the NIM-Neuro 2.0, monitoring electrode and stimulator probe.
P5b	STIM 1 (EMG) Patient Interface fuse blown (32 mA, 250 V, REF 8250615).
P5c	Stimulus set to 0.00 mA.
P5d	Defective stimulating electrode or probe.

To avoid false positive EMG events (stimulus artifacts):

P6a	Ensure the recording electrodes and the stimulator (+) or (-) cabling are routed separately and not tangled.
P6b	Ensure EMG ground (green wire) is physically placed between the stimulator return electrode (white wire with red plug) and the EMG channel input electrodes.

Proper placement and setup of the electrosurgical unit away from the NIM-Neuro 2.0 will reduce or minimize unnecessary muting, interference, and offsets.

Use of unapproved stimulators, stimulus probes, stimulus-dissection instruments or electrodes may result in compromised NIM-Neuro 2.0 operation, such as, but not limited to, decreased accuracy.

Electrode integrity should be checked (on the “electrodes” screen) after electrode insertion and before electrode removal to give additional assurance that electrode continuity was maintained throughout the entire procedure. If electrode impedance is very high, discontinue use and replace.

P10

The Patient Interface cable, and Muting Probe cable should be secured to the floor with tape or other nontrip device.

P11

Excessive or insufficient muting may result from improper muting gain. For excessive muting, move the Muting Probe to a Lower jack number. For insufficient muting, move the Muting Probe to Higher jack number. Standard position is number 3.

P12

To avoid excessive muting:

P12a	Do not place the NIM-Neuro 2.0 in close proximity to the electrosurgical unit.
P12b	Do not place Patient Interface or electrode wires in close proximity to the electrosurgical unit or electrosurgical unit wires.
P12c	Avoid high-power electrosurgical unit monopolar settings. Note that muting caused by electrode charging may last several seconds after electrosurgical Instrument use.
P12d	Be aware of external sources that may induce muting including cellular phones, diathermy, electrocautery used in adjacent operating rooms, or other sources of electromagnetic interference.

P13

Avoid accidental contact between connected but unapplied electrodes and other conductive parts.

P14

Contaminated single use electrodes and probes must be disposed of in an appropriate sharps biohazard container in accordance with hospital or other user facilities policy.

P15

For extra-ocular monitoring, it is recommended that electrode placement be done under the direction of a neurologist or ophthalmologist.

P16

The Patient Interface safety fuse used in all NIM Patient Interfaces Boxes for the Stimulator Output are specifically tested for ECU protection. Use Xomed 11270048 Fuse, 5 x20mm, 32mA, 250 V. Order 8250615 Fuse Kit for replacements.

NIM TRIVANTAGE EMG ENDOTRACHEAL TUBE

NIM TriVantage EMG Endotracheal Tube

Intended Use

The NIM TriVantage™ EMG Endotracheal Tube is intended for use as a means of providing both an open airway for patient ventilation and for intraoperative monitoring of EMG activity of the laryngeal musculature when connected to an appropriate EMG monitor.

Indications for Use

The NIM TriVantage EMG Endotracheal Tube is indicated for use where continuous monitoring of the nerves supplying the laryngeal musculature is required during surgical procedures.

Contraindications

The NIM TriVantage EMG Endotracheal Tube is not intended for postoperative use. The NIM TriVantage EMG Endotracheal Tube should be removed and replaced with a standard endotracheal tube if ventilation is required beyond the surgical procedure.
The use of paralyzing agents will significantly reduce, if not completely eliminate EMG responses to direct or passive neural stimulation.
The NIM TriVantage EMG Endotracheal Tube is not intended for use in infant and neonatal patients.
Do not use the NIM TriVantage EMG Endotracheal Tube in surgical procedures with flammable gases or high temperature generating devices, such as surgical lasers or cauteries inside the airway, to avoid combustion.

Warnings

Do not use local anesthetic gels or creams to lubricate the tube or apply topical anesthetic sprays on the vocal cords. The use of neuromuscular blocking agents will significantly reduce, if not completely eliminate, EMG responses to direct or passive neural stimulation. Whenever nerve paralysis is suspected, consult the anesthesiologist.
Do not attempt to use a NIM TriVantage EMG Endotracheal Tube without first performing a cuff inflation test. Inflate the cuff with air and visually inspect the cuff for any abnormality. Replace with another NIM TriVantage EMG Endotracheal Tube if any adverse abnormality is found.
Failure to use a NIM stimulating device may result in not identifying the location or detecting injury to the nerve. During EMG monitoring only (passive monitoring), neuromuscular tissue may not elicit a response from sharp dissection or all types of manipulation. Use the stimulating device to confirm location and integrity of the nerve.
Avoid false negative responses (failure to evoke a nerve response), which may be caused by:
- Neuromuscular fatigue from prolonged or repeated exposure to electrical stimuli.
- Deep anesthesia, which may suppress neuroelectrical activity of the recurrent laryngeal nerve.
- Insufficient contact between the electrodes and vocal cords due to misplacement or using a tube size that is too small.
- Displacement during the procedure when rotating, flexing, or extending the patient’s head and neck.
Do not use a NIM TriVantage EMG Endotracheal Tube with a high electrode impedance. This may be due to inadequate electrode continuity. Replace with another NIM TriVantage EMG Endotracheal Tube.
Cuff deflation or diffusion of a gas or gas mixture (nitrous oxide, oxygen, air) might result in cuff pressure and volume variation. Monitor the cuff pressure during the procedure.
Do not over-inflate the cuff. Over-inflation may cause cuff deformation, deflation, or rupture resulting in tube blockage and/ or tracheal damage.
Avoid damage to the trachea, larynx, or vocal cords during insertion by inspecting the tube, cuff, and monitoring connections for damage, which may occur if the cuff is over-inflated during set-up testing.
Do not attempt to manipulate a NIM TriVantage EMG Endotracheal Tube with an inflated cuff after insertion. Manipulating a tube with an inflated cuff may cause partial airway blockage at the tip and/or murphy eye, cuff herniation, or tip deflection. Ensure that the cuff is fully deflated before any manipulation and confirm that the airway is free of any potential occlusion after repositioning.
Do not attempt to remove an inflated cuff from the trachea. This may result in cuff deformation and/or injury of the larynx or vocal cords. If resistance is encountered during removal, ensure that the cuff is fully deflated.
Avoid insertion of a suction tube or stylet in a tube that has been distorted by biting or other forces. This may further damage the tube and block the airway.
Do not attempt to straighten bent needles, which may weaken the metal. Improperly placed, weak, or bent needles increase the risk of the needle breaking off in the patient.
Do not excessively bend or flex the electrodes or the electrical integrity may be compromised. Check electrode integrity after insertion.
Avoid inadequate oxygenation and/or tracheobronchial injury, which may be caused by:
- Excessively bending the tube, causing it to kink, or retracting the tube, which may cause it to crush.
- Placement in the right main bronchus (deep intubation) by confirming the correct positioning after intubation.
- A collapsed or blocked tube after performing a test inflation, by inspecting the inner diameter of the tube for patency after test inflation.
Failure to use a bite block may result in patient injury or damage to the tube. The use of a bite block is essential during transcranial motor-evoked potentials (TcMEP) procedures.
To avoid disrupted air supply, confirm, monitor, and maintain anesthesia gas delivery systems and connections at all times.
Do not perform magnetic resonance imaging (MRI) on a patient with a NIM TriVantage EMG Endotracheal Tube in place.
Do not activate the electrosurgical instruments while the stimulator is in contact with tissue or in the surgical field to avoid patient burns.
Do not connect electrode leads to any other types of equipment or connections than EMG recording/monitoring equipment or electrical shock to the patient or user may occur.
Avoid delivery of current to unintended tissues by using an EMG monitor equipped with active audio and/or visual feedback systems for stimulating.
Do not use if sterile package has been opened or is damaged.
Do not attempt to re-sterilize or reuse single use disposable devices. Re-sterilization or reuse may result in device damage and patient injury.
Avoid injury by disposing of the devices in an appropriate sharps biohazard container.
Avoid injury by using extreme care when handling and cleaning instruments with sharp points or edges.

Precautions

It is strongly recommended that the clinician(s) have a thorough understanding of and experience with intraoperative EMG monitoring prior to using the NIM TriVantage EMG Endotracheal Tube in a surgical procedure. This device is not intended to replace the surgeon’s medical judgment or knowledge of neural anatomy and physiology. It is intended to provide the surgeon with an additional tool with which to make better-informed decisions regarding the surgical procedure.
It is strongly recommended that the surgeon consult with the attending licensed medical practitioner who will be administering anesthesia prior to the use of EMG monitoring to review EMG monitoring techniques, goals, and the effects of the administration of anesthesia on neuromuscular activity.
A patient with an implanted electronic device should not be subjected to electrical stimulation unless specialist medical opinion has first been evaluated.
Proper sizing, intubation, and extubation should be in accordance with accepted medical techniques and expert clinical judgment. A tube that is one size larger than standard selection is recommended whenever possible to improve electrode contact with vocal cords. The proper size tube for the patient should be determined prior to intubation by the anesthesia provider and/or surgeon.
For safe and accurate EMG monitoring, proper handling, insertion, and placement of electrodes and probes is critical. Review the appropriate user’s guide for the monitor being used for the procedure.

WARNINGS BEFORE SURGERY

Verify reusable device was sterilized prior to use. If not sterilized, do not use.
Do not use accessory if package is opened or damaged. Broken seal offers no protection against crosscontamination.
Do not operate the XPS 3000 System in the presence of flammable anesthetics. Avoid potential ignition or explosion of gases.
Achieve electrical grounding reliability with proper connections. Connect the XPS 3000 Console to hospital grade receptacles only.
Use adequate irrigation from a separate user-provided irrigating source. The use of a bur without irrigation may cause an inordinate amount of heat buildup resulting in thermal injury to tissue.
When not operating handpiece, ensure that handpiece rests on a non-conductive surface that provides containment for handpiece and blade/bur. Avoid unintended thermal injury by an uncontained handpiece.
When not operating handpiece, eliminate accidental foot control activation. Control energy to and through handpiece to prevent unintended tissue, bone or nerve resection.
This medical device complies with EN60601-1-2 safety standard for electromagnetic compatibility, requirements and test. However, if this equipment is operated in the presence of high levels of electromagnetic interference (EMI) or highly sensitive equipment, interference may be encountered and the user should take whatever steps are necessary to eliminate or reduce the source of the interference. Diminished performance may lengthen operating time for anesthetized patient.
