OBJECTIVE: To explore the method of detecting somatosensory evoked potential of beagle penis under general anesthesia and the change of somatosensory evoked potential during dorsal penile nerve resection, so as to provide reference for further research.
Method: The somatosensory evoked potentials of the glans of the penis and the dorsal nerve of the penis were detected during general anesthesia under general anesthesia of the dorsal penile nerve in 5 beagle dogs, and the waveforms and parameter values were observed.
Results: The GPSEP and DNSEP waveforms of beagle dogs were relatively stable under general anesthesia. The average incubation period of GPSEP in 5 beagle dogs under general anesthesia was (41.84±1.41) ms, and the average amplitude was (1.56±0.26) μV; the average incubation period of DNSEP was (33.46±2.45)ms, average amplitude (1.80±0.52)μV. During the resection of the dorsal penile nerve in Beagle dogs, the latency of DNSEP and GPSEP changed, and the difference was significant (P<0.05).
Conclusion: The detection of penile somatosensory evoked potential under general anesthesia is feasible, and the waveform is relatively stable; DNSEP and GPSEP latency may change during dorsal penile nerve resection, which is expected to provide experimental animal basis for further research.
