The questionnares was used to get patients’ anxiety and depression conditions and their general status.Results①The mean anxiety scores of ICU patients was45.81±8.22, it was significantly higher than the normal samples(29.78±8.22), the difference was statistically significant. Patients those are female, without application of sedation and analgesia, feel lonely obviously for the abscence of relatives’accompany gained a higher score, the difference was statistically significant. As their ages, days in ICU, days of mechanical ventilation, numbers of pipe, severity of disease increased, the score increased, the rate of anxiety increased, the difference was statistically significant. Patients with different occupations gained different score, and their anxiety rate was different, the difference was statistically significant.

As their ages, days in ICU, days of mechanical ventilation, numbers of pipe, severity of disease increased, the SDS score increased, the rate of depression increased. The difference was statistically significant. The depression level of patients with different occupations and medical insurance was significantly different, so was their depression rate. Groups by sedation and analgesia, free expression gained no significant difference in SDS score, but the depression rate was statistically significant.. There were significant difference in SDS score in groups by educational status, while difference in depression rate was not significant..Conclusion:A high level of anxiety and depression existed in ICU patients.
