Vagus Nerve Monitoring is employed during surgeries risking vagus nerve injury, crucial for heart rate, digestion, and vocal functions. Using specialised electrodes to continuously measure the vagus nerve’s electrical activity provides real-time feedback to the surgeon. Particularly valuable in thyroidectomy, parotidectomy, and other neck or chest surgeries, where inadvertent vagus nerve damage can lead to serious complications. By identifying and preserving the vagus nerve, this monitoring technique helps prevent postoperative complications such as voice changes, swallowing difficulties, and irregular heart rhythms, thereby enhancing patient safety and surgical outcomes.
