Objective To investigate the effects of Stilnox on brain electrical activity in patients with insomnia using QUISI sleep instrument. Methods QUISI sleep instrument was employed  for 32 patients with insomnia for 3 consecutive nights, among whom 10 mg Stilnox was administrated before sleep on the third night, and the changes of AUISI parameters were observed after Stilnox administration. Another 28 normal controls were selected, and received one night of acclimatization and the other night of baseline QUISI monitoring. Results There were significant differences in QUISI parameters between patients with insomnia and normal controls before Stilnox administration (P<0.05 or P<0.01). Compared with those before Stilnox administration, patients with insomnia had improved sleep efficiency [(87.7±7.3%)% vs (91.4±3.8)%], reduced awake time [(40.5±15.5) min vs (22.1±6.1) min], reduced S1 [(29.9±18.3)% vs (16.1±6.5)%], increased S2 [(43.9±17.3)% vs (59.1±4.7)%] and shortened sleep latency [(35.7±17.0)min vs (21.1±11.0)min] after Stilnox administration(P<0.05 or P<0.01). Conclusion Stilnox not only can improve the subjective evaluation on sleep, but also have effects on brain electrical activity in night in patients with insomnia.
