Abstract:
Objective To explore the effects of ICU night noise management on ICU nighttime noise, patient sleep quality and delirium incidence. Methods ICU of a Class Ⅲ Grade A hospital in Harbin has implemented comprehensive noise management measures since January 2017. A total of 82 patients were recruited before implementation (October to December 2016), and 78 patients were recruited after implementation (February to April 2017). ICU nighttime noise, patient sleep quality and delirium incidencewere compared after the implementation of ICU nighttime noise management. Results The equivalent sound level of ICU nighttime noise was (58.34±6.21) dB before the implementation of nocturnal noise management and (46.33±4.17) dB after the implementation, and the difference was statistically significant (t=15.139, P＜0.05). The sleep quality was (72.9±2.9) after the intervention, which was higher than before. The amount of sedative drugs was (67.6±6.3) mg, which was lower than before. The differences were statistically significant (t=-20.476, 13.285;P＜ 0.05). The incidence of delirium in patients was before and after intervention was 51.3% and 29.3% respectively, and the difference was statistically significant (χ2=5.403, P＜0.05). Conclusions Noise management measures at night in ICU ward can reduce noise at night, improve sleep quality and reduce the incidence of delirium. It is of great significance to improve nursing effect.
