EMG Risk Management & Mitigation 2

Question 1

A patient with a pacemaker is referred for EMG. What is the primary risk management concern?

Accepted Answer

Electromagnetic interference potentially affecting pacemaker function

Answer

EMG electrical stimulation can cause electromagnetic interference with pacemakers, requiring coordination with the patient's cardiologist and use of bipolar electrodes when necessary.

Question 2

Which action best mitigates the risk of cross-contamination between patients during EMG procedures?

Accepted Answer

Using single-use disposable needle electrodes for each patient

Answer

Single-use disposable needle electrodes eliminate the risk of bloodborne pathogen transmission between patients and are the standard of care in EMG practice.

Question 3

During an EMG, a patient suddenly reports dizziness and appears pale. What is the most likely cause and appropriate response?

Accepted Answer

Vasovagal syncope — recline patient, elevate legs, monitor vitals

Answer

Vasovagal syncope is a common reaction to needle procedures; placing the patient supine and elevating the legs restores cerebral perfusion.

Question 4

What is the recommended waiting period before performing EMG on a patient who received thrombolytic therapy?

Accepted Answer

At least 10 days

Answer

Thrombolytic therapy significantly increases bleeding risk, and most guidelines recommend waiting at least 10 days before performing needle EMG to reduce hematoma risk.

Question 5

A patient is found to have INR of 4.5 on the day of their EMG. Which muscle group poses the GREATEST bleeding risk if needle examination is performed?

Accepted Answer

Paraspinal muscles

Answer

Paraspinal muscles are located near major vascular structures and deep compartments, making hematoma formation in this region particularly dangerous in anticoagulated patients.
