Ketamine is particularly desirable for pediatric patients during Transcranial Electrical Motor Evoked Potential (TCeMEP) monitoring due to its unique pharmacological properties. One of the key advantages of ketamine is its ability to provide sedation while preserving airway reflexes and cardiovascular stability, which is essential in the pediatric population. This characteristic allows for easier management of the airway and reduces the risk of respiratory depression compared to other agents.

Additionally, ketamine is known for its analgesic properties, which can contribute to a more comfortable experience for younger patients undergoing surgery. Its dissociative effects can also facilitate smoother induction and emergence from anesthesia, which can be beneficial in maintaining a stable neuromonitoring environment during TCeMEP.

While other anesthetic agents such as isoflurane, propofol, and etomidate are used in various clinical scenarios, they may not be as favorable in the context of TCeMEP. Isoflurane, for instance, can significantly depress motor evoked potentials, making it less desirable. Propofol, although commonly used for its quick onset and recovery, may lead to more pronounced hypotension and respiratory depression. Etomidate, known for its hemodynamic stability, is primarily utilized for its minimal
