Abstract: Objective To investigate the effect of white noise intervention on the dosage of sedative drugs in ICU patients. Methods A total of 96 patients admitted to the Emergency Intensive Care Unit(EICU)of a level-III first-class hospital in Hebei province from January 1, 2019 to June 30, 2019 were randomly divided into a test group and a control group, 48 patients in each group. During the observation period, the observation group was given 50-60 decibels of white noise for intervention at 22:00-06:00 daily. Patients in the control group were exposed to normal ambient sounds. Results The maintenance dose of dexmedetomidine was(0.34±0.07)μg/(kg·h)in the observation group and(0.40±0.10)μg/(kg·h)in the control group, and the difference between the two groups was statistically significant(P<0.05). Conclusion White noise intervention can enhance the sedative effect of sedative drugs and reduce the dosage of sedative drugs.
