An in vivo rat model for comparing selective blockade between sensory and motor nerve conduction.

ABSTRACT: Sensory-selective nerve blockade is highly useful for pain management in clinical practice, but developing such blockers remains challenging. A major handicap is the lack of objective in vivo animal models to evaluate motor and sensory nerve conduction simultaneously. Due to anatomical structures, motor evoked potentials (MEPs) and/or somatosensory evoked potentials (SSEPs) may be used to assess nerve conduction. MEPs were elicited by stimulating motor cortex and recorded from contralateral hind limb. SSEPs were generated by stimulating sciatic nerve and recorded from contralateral sensory cortex. Amplitude/latency changes were recorded under various physiological conditions (e.g., anesthesia, durations, temperatures, and oxygen) and drug interventions for validation. Compared to sevoflura
