What is the recommended secure method for applying surface cup electrodes?

The recommended secure method for applying surface cup electrodes involves using collodion combined with compressed air. Collodion is a viscous solution that provides excellent adhesion and can create a strong bond between the electrode and the skin. Its use is particularly beneficial in intraoperative environments, where electrodes must remain securely in place for extended periods or even in the presence of sweat or other conditions that could compromise adhesion.

The application of compressed air additionally enhances the adhesion process, allowing collodion to dry more quickly and securely. This method ensures that the electrodes maintain good contact with the skin, which is crucial for accurate and reliable neurophysiological readings during surgery.

Other options, while viable methods in certain contexts, may not provide the same level of security or reliability essential for intraoperative monitoring.
