Median nerve somatosensory evoked potentials (SSEP) were studied in 10 ASA I patients during general anaesthesia with propofol, vecuronium and fentanyl after premedication with diazepam. N14 and N20 latencies, central conduction time (CCT) and corresponding interpeak amplitudes were assessed at induction, after intubation, during steady state, at re-commencement of spontaneous breathing and during early recovery. Data were compared with pre-induction values. Median nerve SSEP were reproducible throughout the procedure and wave forms were suitable for assessment of neurological disorders. Intra-individual changes were considerable for latencies and amplitudes.
在10例ASA I级患者中,在使用地西泮进行术前用药后,采用丙泊酚、维库溴铵和芬太尼进行全身麻醉期间,研究正中神经体感诱发电位(SSEP)。在诱导期、插管后、稳态期、自主呼吸重新开始时以及早期恢复期间,评估N14和N20潜伏期、中枢传导时间(CCT)以及相应的峰间振幅。将数据与诱导前值进行比较。在整个手术过程中,正中神经SSEP具有可重复性,波形适合评估神经系统疾病。潜伏期和振幅的个体内变化相当大。
