The present study was designed to evaluate the effects of the controlled sleeping environment and the stress of laparotomy patients in ICU.
In the first study, 40 patients who were operated on laparotomy in K General Hospital were allocated to the experimental group or the control group, however, 5 patients in control group who had insufficient data had been eliminated from the list. 15 experimental group and 20 control group performed this designed true experiment. For treatment efficiency, 20 isolated bed type were given to the experimental group and rest 20 control group were assigned to the open bed type according to the order of precedence.
Environmental factors such as noise, light, temperature of ICU were controlled for experimental group. On the contrary, for control group, physical factors like treatment and pain, emotional factors like emotional support were controlled. To easily control environment factors such as temperature, humidity, light, noise, odor, aesthetic elements, isolated bed type were allocated to the experimental group.
Measurements were undertaken using VSH(verran & synder-Halpern) sleep scale and VAS(Visual Analogue Scale). And quality of sleep, subjective stress, and objective stress were measured through Serum Cortisol.
Collected data was using the SPSS WIN 20.0 program and the general characteristics of the subjects are calculated as a percentage of real number and the percentage. The general characteristics of the group and homogeneity was used the mean and standard deviation, χ2-test, t-test. test for difference in the measured variable were analyzed by t-test and two-way repeated measure ANOVA.
Conclusion
1. The general characteristics of the study subjects, disease characteristics, and homogeneity of the measured variables all results were homogeneous.
2. Compared by measuring the quality of sleep before and after two groups, showing a significant higher quality of sleep was sleeping environment mediated the experimental group than the control group.
3. Compared by measuring Subjective stress before and after two groups, showing a significant low-stress (was sleeping environment mediated) the experimental group than the control group.
4. Compared by measuring Objective stress (Cortisol Before and After) in the two groups, showing a significant lower levels of cortisol the experimental group than the control group.
Significant
1. this study is demonstated improve the quality of sleep and effective in the reduction of stress the physical, emotional, and environmental areas of sleep disturbance factors of physical and emotional factors alone than sleep Intervention conducted a comprehensive environmental sleep interventions that
2. this study is suggested physiological basis of subjective stress, by measured at the same time subjective stress associated sleep and cortisol.
3. by evaluating the quality of sleep and stress, we could confirm the importance of the intervention for sleep environment in ICU.
4. this study provide basic date to prepare for sleep and stress the need for further studies and clinical guidelines alert patient without limited laparotomy patients in ICU
5. we observed the effectiveness of the intervention for sleep environment in ICU.
