How often should a transcutaneous electrode site be changed?

Changing the transcutaneous electrode site every 4 hours is important for maintaining skin integrity and ensuring the effectiveness of the stimulation. This frequency helps to prevent skin irritation and potential skin breakdown that can occur with prolonged contact of the electrodes in the same location.

Transcutaneous electrical nerve stimulation (TENS) and other forms of nerve stimulation involve the application of electrodes that can impact the skin's health over time. If electrodes are left in the same place for too long, the skin may not have adequate time to recover between applications. Rotating the electrode site at regular intervals allows for healing and decreases the risk of adverse skin reactions.

Other options suggest longer intervals, which might increase the risk of skin complications, and do not align with best practices in managing patient care for those using transcutaneous electrodes. Therefore, changing the site every 4 hours is optimal for patient comfort and safety.
