The effects on median nerve somatosensory evoked potentials produced by nitrous-oxide (67%) were studied in 20 patients undergoing elective surgery under enflurane or isoflurane anaesthesia. This study demonstrates that nitrous-oxide does not significantly modify spinal (N13) and cortical (N20) component latencies nor central conduction time. The addition of nitrous-oxide to enflurane or isoflurane (up to 1 MAC) causes a significant reduction of N20 amplitude.
在20例接受安氟醚或异氟醚麻醉下择期手术的患者中，研究了氧化亚氮（67%）对正中神经体感诱发电位的影响。本研究表明，氧化亚氮不会显著改变脊髓（N13）和皮质（N20）成分的潜伏期以及中枢传导时间。在安氟醚或异氟醚中加入氧化亚氮（高达1个最低肺泡有效浓度）会导致N20波幅显著降低。
