Objectives : This study was carried out to determine whether the state anxiety may affect sleep on the night before surgery. Methods : The researcher examined the clinical charts of patients who were scheduled to receive surgery by general anesthesia the following day and then had semistructural interview with patients. In addition Spielberger's State Anxiety Inventory(1972), presleep questionnaire and postsleep questionnaire were administered to the patients. One hundred patients who responded to the questions were divided into three groups based on the state anxiety scores; low(n=35), middle(n=27) and high(n=38). Demographic and clinical characteristics of patients, some possible factors affecting sleep, daytime status and nighttime sleep before surgery were compared among three groups. Results : 1) There was no significant difference in demographic characteristics and some possible factors affecting sleep on the night before surgery among three groups. 2) In terms of clinical characteristics, the expectancy of surgical result was significantly different among three groups. More patients in low anxiety group than in middle and high anxiety groups, predicted surgical results as good, while more patients in middle and high anxiety groups than in low anxiety group could not predict their surgical results. 3) For daytime status, high anxiety group felt more tired compared to low anxiety group, but there was no significant difference in daytime nap among three groups. 4) For nighttime sleep before surgery, high anxiety group expected poor sleep and in fact, waked more frequently during sleep than low anxiety group. However there was no difference in bed time, sleep latency, rise time, total sleep time, sleep depth and sleep quality among three groups. 5) The need for hypnotics was higher before bedtime and also after rise in high anxiety group compared to low anxiety group. Conclusions : These results indicate that the individuals with high state anxiety before surgery have poor sleep and furthermore suggest that anxiolytics and/or hypnotics may be required to decrease anxiety and improve sleep for those with high state anxiety.

Purpose: This study was performed to evaluate the quality of sleep in snoring obese children without obstructive sleep apnea (OSA); and to study the possible relationship between sleep interruption and gastroesophageal reflux (GER) in snoring obese children. Methods: Study subjects included 13 snoring obese children who were referred to our sleep lab for possible sleep-disordered breathing. Patients underwent multichannel intraluminal impedance and esophageal pH monitoring with simultaneous polysomnography. Exclusion criteria included history of fundoplication, cystic fibrosis, and infants under the age of 2 years. Significant association between arousals and awakenings with previous reflux were defined by symptom-association probability using 2-minute intervals. Results: Sleep efficiency ranged from 67-97% (median 81%). A total of 111 reflux episodes (90% acidic) were detected during sleep, but there were more episodes per hour during awake periods after sleep onset than during sleep (median 2.3 vs. 0.6, p=0.04). There were 279 total awakenings during the sleep study; 56 (20.1%) of them in 9 patients (69.2%) were preceded by reflux episodes (55 acid, 1 non-acid). In 5 patients (38.5%), awakenings were significantly associated with reflux. Conclusion: The data suggest that acid GER causes sleep interruptions in obese children who have symptoms of snoring or restless sleep and without evidence of OSA.

Purpose: The purpose of this study was to identify the relationship of job stress, state of sleep, and depression and to identify factors influencing depression of emergency medical technicians. Methods: The research was a cross-sectional, descriptive study. Data collection were done using self-report questionnaires with 162 emergency medical technicians working in hospitals who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression with the SPSS/WIN 18.0 Program. Results: Depression had significant negative correlations with state of sleep, (r=-482, p<.001) and positive correlations with job stress (r=.196,p=.013). State of sleep had significant negative correlations with job stress (r=-.168, p=.033). The variance for life satisfaction was 23.7% (F=25.964, p<.001). Variable of state of sleep significantly predicted depression of emergency medical technicians. Conclusion: Considering these results, for emergency medical technicians' job stress, state of sleep, and depression, further studies are needed. Furthermore, there is a need to develop and implement new strategies to improve depression among emergency medical technicians.

Purpose: The study was done to identify factors influencing the sleep of elderly women. Methods: Data were collected by questionnaires from 203 elderly women in Seoul and Gyeong-gi province. Measures were physical health state, family support, life satisfaction, sleep, depression, and quality of life. Data were analyzed using Pearson correlation coefficients, t-test, ANOVA, and stepwise multiple regression with SPSS/WIN 13.0 version. Results: The mean score for sleep for elderly women was 39.04. Sleep for elderly women according to religion, education level, spouses, and monthly income showed significant differences. Sleep for elderly women showed significantly positive correlations to physical health state, family support, life satisfaction, and quality of life. The significant factors influencing sleep of elderly women were physical health state, family support, depression, and quality of life, which explained about 70.4% of the variance. The strongest factors influencing the sleep was physical health state. Conclusion: The results suggest that in developing nursing interventions and practice for sleep pattern of elderly women spouses and family support should be considered.

Objectives : Insomnia is significantly influenced by the pre-sleep arousal, self efficacy, sleep hygiene, depression and anxiety. The authors tried to explore how these factors are related with the clinical features of sleep. Methods : Fifty three patients diagnosed as insomnia by DSM-IV criteria were studied. They filled up the pre-sleep arousal scale(PSAS), sleep efficacy scale(SES), sleep hygiene awareness and practice scale, BDI, and state and trait anxiety scales. Results: 1) The mean values of sleep-related variables were as follows : Sleep latency,136.89 minutes ; frequences of awakening during a night, 2.28 ; minutes to get back to sleep, 42.70 ; total sleep time, 180.19 minutes ; duration of illness, 72.00 months. 2) The mean scores of scales were as follows : PSAS(cognitive), 22.40 ; PSAS(somatic), 17.32 ; SES, 20.16 ; sleep hygiene knowledge, 25.96 ; caffein knowledge, 59.78 ; sleep hygiene practice, 42.12 ; BDI. 18.2 ; state anxiety, 41.24 ; trait anxiety ; 44.50. 3) In the subjects with superimposed depression, the mean frequency of awakening during a night and the mean pre-sleep arousal scale score were higher than in those without depression. 4) Frequency of awakening were correlated positively with a PSAS(a tight tense feeling in your muscle) and sleep hygiene awareness. PSAS(cognitive) were correlated positively with a PSAS(somatic). BDI correlated positively with a PSAS item(a jittery, nervous feeling in your body)and a SES item (not allow a poor night's sleep to interfere with daily activities). Anxiety scales were correlated positively with sleep hygiene practice scale sleep, and PSAS were correlated negatively with SES. Conclusions : The mean scores of PSAS, SES, sleep hygiene awareness and practice scale, BDI, state and trait anxiety scales of insomniacs were correlated either positively or negatively in insomnia patients. These factors seem to contribute to the development and maintainence of insomnia.

Purpose: Most of postoperative patients experience pain, state anxiety and sleep disturbance. These problems negatively influence the recovery of postoperative patients. So alleviating these problems has been one of the nurses' central roles. The purpose of this study was to examine the effects of back massage on pain, state anxiety and quality of sleep of postoperative gastrectomy patients. Methods: A non-synchronized non-equivalent control group pre and post-test design was used. The research instruments used in this study were the Numerical Rating Scale (NRS) for pain, the State-Anxiety Inventory (STAI) for anxiety and the Verran and Synder-Halpern scale for quality of sleep. The subjects were patients admitted to a university hospital located in D city. Twenty-nine patients in the experimental group had a 10 minute manual back massage stimulation for 5 days from the 1st day to the 5th day after their operation, and 25 patients in the control group did not. Results: The degree of pain was significantly reduced according to post operation day and quality of sleep was significantly increased. However state anxiety was not significantly reduced. Conclusion: Back massage is a partially effective nursing intervention for postoperative patients with gastrectomy who experience pain and sleep disturbance.

The sleep homeostatic response significantly affects the state of anesthesia. In addition, sleep recovery may occur during anesthesia, either via a natural sleep-like process to occur or via a direct restorative effect. Little is known about the effects of isoflurane anesthesia on sleep homeostasis. We investigated whether 1) isoflurane anesthesia could provide a sleep-like process, and 2) the depth of anesthesia could differently affect the post-anesthesia sleep response. Nine rats were treated for 2 hours with $ad$ $libitum$ sleep (Control), sleep deprivation (SD), and isoflurane anesthesia with delta-wave- predominant state (ISO-1) or burst suppression pattern-predominant state (ISO-2) with at least a 1-week interval. Electroencephalogram and electromyogram were recorded and sleep-wake architecture was evaluated for 4 hours after each treatment. In the post-treatment period, the duration of transition to slow-wave-sleep decreased but slow wave sleep (SWS) increased in the SD group, but no sleep stages were significantly changed in ISO-1 and ISO-2 groups compared to Control. Different levels of anesthesia did not significantly affect the post-anesthesia sleep responses, but the deep level of anesthesia significantly delayed the latency to sleep compared to Control. The present results indicate that a natural sleep-like process likely occurs during isoflurane anesthesia and that the post-anesthesia sleep response occurs irrespective to the level of anesthesia.

The purpose of this study was to investigate relationship among the depression, physical condition, daily living activities, and sleep state among old people at elderly care facilities. The subjects include old people aged 65 or older residing at an elderly care facility. At elderly care facilities, the depression of old people was related with the state of vision, mastication ability, quality of sleep, and sleep state. The degree of relation was high in the group with a poor vision, the one with a bad condition of teeth, the one that considered their quality of sleep to be poor, and the one with somnipathy. Their depression had negative correlations with age and positive ones with mastication ability and assessment of quality of sleep. At elderly care facilities, the depression of old people was highly connected with the state of vision, mastication ability, sleep state, and hearing ability. In short, the depression of old people at elderly care facilities is highly connected to the health state perceived individually. The findings point to the importance of close interest in individual health state and management of old people in poor vision, mastication ability in healthcare and nursing intervention.

Purpose: The study aimed to examine the effects of aroma hand massage on state sanxiety, depression, quality of sleep, and blood pressure levels of palliative patients in hospice. Methods: This study was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 48 palliative patients in hospice (experimental group: 24, control group: 24). The aroma hand massage was given to the experimental group once a day for 5 days. Data were collected between December 2017 to February 2018. Data were analyzed using SPSS 20.0 program with the chi-square test, Fisher's exact test, independent t-test, and repeated measurement analysis of variance(ANOVA). Results: There were significant differences in state anxiety levels (t=2.41, p=.020) and quality of sleep (F=14.29, p<.001). However, significant differences in the levels of depression (t=1.59, p=.119), systolic blood pressure (F=0.37, p=.695), and diastolic blood pressure (F=0.37, p=.695) were observed. The aroma hand massage was effective in improving the quality of sleep and state anxiety levels of palliative patients in a hospice. Conclusion: The aroma hand massage was effective in improving the quality of sleep and state anxiety in a hospice.
