What is Electronystagmography (ENG)?
Electronystagmography (ENG) is a diagnostic test used to evaluate patients with dizziness, vertigo, or balance disorders. It measures the involuntary movements of the eyes, known as nystagmus, which can be indicative of underlying issues within the vestibular system.
Why is ENG Important in Nursing?
For nurses, understanding ENG is crucial because it helps in assessing patients with balance and dizziness complaints. Proper knowledge of ENG allows nurses to prepare patients for the test, interpret preliminary results, and contribute to the overall management plan.
Preparation: The patient is advised to avoid caffeine, alcohol, and certain medications before the test.
Electrode Placement: Electrodes or goggles are placed around the eyes to record eye movements.
Testing Procedures: The test includes various procedures such as gaze tests, positional tests, and caloric tests. Each aims to provoke nystagmus in a controlled manner.
Providing detailed instructions about dietary and medication restrictions.
Explaining the procedure to alleviate any anxiety.
Ensuring the patient understands the importance of following pre-test guidelines.
Monitoring the patient’s comfort and safety.
Assisting the technician with electrode placement and adjustments.
Documenting any patient reactions or symptoms for further analysis.
Ensure the patient is stable and comfortable before discharge.
Provide post-procedure instructions, including activity limitations if any.
Communicate results and follow-up plans with the patient and the healthcare team.
Conclusion
Understanding electronystagmography (ENG) is essential for nurses involved in the care of patients with balance and dizziness issues. Proper patient preparation, monitoring, and post-test care are critical components of the nursing role in ensuring the efficacy and safety of the ENG procedure.
