Clinical Study On The Effect Of White Noise On Sleep Quality And Negative Emotion Of Patients After Mechanical Ventilation Extubation In ICU

Objective:To explore the influence of white noise intervention on sleep quality and negative emotions of patients after mechanical ventilation extubation in ICU,a nd to explore a simple and effective nursing intervention for promoting sleep nursing and psychological nursing of patients after mechanical ventilation extub ation in ICU.Methods:A experimental clinical study was conducted to select 66 patients with me chanical ventilation after extubation from general ICU and specialized ICU of t he First Affiliated Hospital of Nanchang University from June 2018 to April 2019.There were 33 cases in the control group and 33 cases in the white nois e group.The control group was given routine nursing,while the white noise g roup was given 40~60DB white noise intervention for one week,three times a day,30 minutes each time on the basis of routine nursing.China Richards C ampbell Sleep Questionnaire(C-RCSQ),China State Anxiety Inventory(C-SAI)and China Self-rating Depression Scale(C-SDS)were used to evaluate the eff ects of white noise on subjective sleep quality and negative emotions in the t wo groups.Sleep breathing screening apparatus was used to monitor the sleepi ng status of the two groups at night.SPSS19.0 software was used for data sta tistical analysis.Counting data were expressed in frequency and percentage,an d?~2 was used for statistical analysis.Measuring data were expressed in mean±standard deviation or quadruple digits,and t test or non-parametric Mann-Wh imey U rank sum test was used for statistical analysis.Results:1.Baseline data:A total of 66 ICU patients(33 in the control group and 33 in the white noise group)completed the data collection.The subjects in the two groups were age,sex,APACHEII score,COPT pain score,type of mechanical ventilation,duration of mechanical ventilation in ICU,intervention site,basic disease system,education,marital status,previous occupation,working status,family income and expenses.There was no significant difference in demographic data and clinical data such as mode and family support(P>0.05).2.Sleep quality evaluation results:(1)There were no significant differences in C-RCSQ scores(sleep depth,difficulty in falling asleep,night waking,difficulty in falling asleep and overall sleep quality,total C-RCSQ scores,Sleep Efficiency Index(SEI)and subjective nocturnal noise perception between the two groups before intervention(P>0.05).There were significant differences in C-RCSQ scores,total C-RCSQ scores,SEI and subjective perception of nocturnal noise between the two groups after intervention(P<0.05).There were no significant differences in C-RCSQ scores,total C-RCSQ scores,SEI and subjective perception of nocturnal noise between the two groups before and after intervention(P>0.05).There was no significant difference in C-RCSQ scores before and after intervention in the white noise group,but there were significant differences in total C-RCSQ scores,SEI and subjective perception of night noise(P>0.05).(2)There were no significant differences in awake period,rapid eye movement period,shallow sleep period,deep sleep period,proportion and sleep efficiency between the two groups before intervention(P>0.05).There were no significant differences in waking time,REM time,shallow sleep time and proportion,sleep efficiency between the two groups(P>0.05),but there were significant differences in deep sleep time and proportion(P<0.05).There were no significant differences in awake period,REM period,shallow sleeping period,deep sleeping period time and proportion,and sleep efficiency before and after intervention in the control group(P>0.05).There was no significant difference in waking time,rapid eye movement time,shallow sleep time,proportion of rapid eye movement and proportion of shallow sleep period before and after intervention in white noise group(P>0.05),but there were significant differences in time and proportion of deep sleep period,proportion of waking period and sleep efficiency(P<0.05).3.There was no significant difference in C-SAI score and C-SDS score between the two groups before intervention(P>0.05).There were significant differences in C-SAI score,C-SDS score and difference between the two groups after intervention(P<0.05).There were significant differences in C-SAI score and C-SDS score between the two groups before and after intervention(P<0.05).The level of anxiety and depression in the control group increased after intervention,while that in the white noise group decreased after intervention.Conclusion:1.Sleep quality of patients with mechanical ventilation in ICU is poor after extubation.White noise intervention can reduce the sensitivity of patients with mechanical ventilation in ICU to environmental noise,improve the subjective sleep quality of patients,increase the time and proportion of deep sleep recovery after mechanical ventilation in ICU,and improve the sleep efficiency of patients..2.Patients with ICU mechanical ventilation after extubation have a certain degree of anxiety and depression negative emotions,and increase with the length of hospitalization.White noise intervention can reduce the level of anxiety and depression in patients with ICU mechanical ventilation after extubation,and stabilize the psychological state of patients.
