Transcranial magnetic motor evoked potentials were recorded from the extensor carpi radialis muscle of the forelimbs and from the cranial tibial muscle of the hindlimbs of anaesthetised dogs. The dogs were premedicated with droperidol and fentanyl and a light plane of anaesthesia was induced and maintained with sufentanil and nitrous oxide. The potentials recorded under sufentanil and nitrous oxide anaesthesia were suppressed in comparison with baseline recordings under droperidol and fentanyl sedation: their latencies were significantly increased and their amplitudes significantly decreased (P < 0.05). However, the potentials could be recorded reliably in all the dogs and with very good reproducibility. This narcotic anaesthesia also allowed sensory evoked potentials to be recorded reliably.
在麻醉犬的前肢桡侧腕伸肌和后肢胫前肌记录经颅磁运动诱发电位。犬只先用氟哌利多和芬太尼进行预处理,然后用舒芬太尼和氧化亚氮诱导并维持浅麻醉状态。与氟哌利多和芬太尼镇静下的基线记录相比,舒芬太尼和氧化亚氮麻醉下记录的电位受到抑制:其潜伏期显著延长,波幅显著降低(P<0.05)。然而,所有犬只均能可靠记录到电位,且重复性很好。这种麻醉方法也能可靠记录感觉诱发电位。
