What advantage do platinum epidural electrodes have over other types?

Platinum epidural electrodes are known for their biocompatibility, which significantly reduces the risk of neurotoxicity compared to other materials, such as stainless steel or gold. This biocompatibility stems from platinum's inert nature, meaning it does not easily react with body tissues or fluids, thereby minimizing potential inflammatory responses or damage to neural structures. As a result, when these electrodes are used for monitoring or stimulation in neurophysiological procedures, they provide a safer option for patients, particularly in sensitive contexts such as intraoperative monitoring.

In contrast, while other electrode types may offer various benefits, such as cost-effectiveness or ease of placement, they do not consistently provide the same level of safety concerning neurotoxic effects. Reducing neurotoxicity is crucial, particularly in sensitive environments such as the epidural space, where local reactions could lead to complications or alter the patient’s neurological status. Hence, the primary advantage of using platinum in this context is its ability to lower the risks associated with neurotoxicity.
