Comparing the effect of sedation with dexmedetomidine and propofol on sleep quality of patients after cardiac surgery: A randomized clinical trial.

Sleep quality is the main concern of patients after cardiac surgery. We compared the effect of two routinely used sedatives on the sleep quality of patients admitted to the intensive care unit (ICU) after cardiovascular surgery. It is a prospective, controlled, randomized clinical trial. A total of 120 patients, after cardiac surgery were enrolled. During extubating, patients were randomized into two groups: 60 patients received an infusion of dexmedetomidine (precede; 0.5 μg/kg/h), and 60 patients received 50 μg/kg/min propofol for 6 hours. Baseline characteristics were compared between the groups. The patients completed the St. Mary's Hospital Sleep Questionnaire, and the scores were compared between the groups. The groups were not different in terms of demographics, underlying diseases, smoking/drug abuse/alcohol, number of vessels involved, history of non-cardiac surgery, and mean levels of serum parameters (P>0.05). Most of the medications used were similar between the groups (P>0.05), except calcium channel blockers (more frequently used in the propofol group [P=0.027). The details of surgery were not statistically significant different (P>0.05); but, the mean volume of platelet received after the surgery was higher in propofol group (P=0.03). The propofol group had less problems with last night's sleep (0 vs 0.1±0.66), felt more clear-headed (4.9±0.6 vs 4.68±0.58, were more satisfied with their last night's sleep (52.1% vs 47.9%), but spent more time getting into sleep (0.38±1.67 vs 0 ) (P<0.5). The sleep quality of patients under the influence of propofol seemed to be better than dexmedetomidine after cardiac surgery.

Associations of Subjective Sleep Quality with Wearable Device-Derived Resting Heart Rate During REM Sleep and Non-REM Sleep in a Cohort of Japanese Office Workers.

Associations between subjective sleep quality and stage-specific heart rate (HR) may have important clinical relevance when aiming to optimize sleep and overall health. The majority of previously studies have been performed during short periods under laboratory-based conditions. The aim of this study was to investigate the associations of subjective sleep quality with heart rate during REM sleep (HR REMS) and non-REM sleep (HR NREMS) using a wearable device (Fitbit Versa). This is a secondary analysis of data from the intervention group of a randomized controlled trial (RCT) performed between December 3, 2018, and March 2, 2019, in Tokyo, Japan. The intervention group consisted of 179 Japanese office workers with metabolic syndrome (MetS), Pre-MetS or a high risk of developing MetS. HR was collected with a wearable device and sleep quality was assessed with a mobile application where participants answered The St. Mary's Hospital Sleep Questionnaire. Both HR and sleep quality was collected daily for a period of 90 days. Associations of between-individual and within-individual sleep quality with HR REMS and HR NREMS were analyzed with multi-level model regression in 3 multivariate models. The cohort consisted of 92.6% men (n=151) with a mean age (± standard deviation) of 44.1 (±7.5) years. A non-significant inverse between-individual association was observed for sleep quality with HR REMS (HR REMS -0.18; 95% CI -0.61, 0.24) and HR NREMS (HR NREMS -0.23; 95% CI -0.66, 0.21), in the final multivariable adjusted models; a statistically significant inverse within-individual association was observed for sleep quality with HR REMS (HR REMS -0.21 95% CI -0.27, -0.15) and HR NREMS (HR NREMS -0.21 95% CI -0.27, -0.14) after final adjustments for covariates. The present study shows a statistically significant within-individual association of subjective sleep quality with HR REMS and HR NREMS. These findings emphasize the importance of considering sleep quality on the individual level. The results may contribute to early detection and prevention of diseases associated with sleep quality which may have important implications on public health given the high prevalence of sleep disturbances in the population.

Associations Between Repetitive Negative Thinking and Objective and Subjective Sleep Health in Cognitively Healthy Older Adults.

Poor sleep and high levels of repetitive negative thinking (RNT), including future-directed (ie, worry) and past-directed (ie, brooding) negative thoughts, have been associated with markers of dementia risk. The relationship between RNT and sleep health in older adults is unknown. This study aimed to investigate this association and its specificities including multiple dimensions of objective and subjective sleep. This study used a cross sectional quantitative design with baseline data from 127 cognitively healthy older adults (mean age 69.4 ± 3.8 years; 63% female) who took part in the Age-Well clinical trial, France. RNT (ie, worry and brooding) levels were measured using the Penn State Worry Questionnaire and the Rumination Response Scale (brooding subscale). Polysomnography was used to assess sleep objectively, and the Pittsburgh Sleep Quality Index and the St. Mary's Hospital Sleep Questionnaire were used to measure sleep subjectively. In primary analyses the associationsbetween RNT and sleep (ie, objective sleep duration, fragmentation and efficiency and subjective sleep disturbance) were assessed via adjusted regressions. Higher levels of RNT were associated with poorer objective sleep efficiency (worry: β=-0.32, p<0.001; brooding: β=-0.26, p=0.002), but not objective sleep duration, fragmentation, or subjective sleep disturbance. Additional analyses, however, revealed differences in levels of worry between those with short, compared with typical and long objective sleep durations (p < 0.05). In cognitively healthy older adults, RNT was associated with sleep characteristics that have been implicated in increased dementia risk. It will take additional research to ascertain the causal link between RNT and sleep characteristics and how they ultimately relate to the risk of developing dementia.

Stellate Ganglion Block Improves Postoperative Sleep Quality and Analgesia in Patients with Breast Cancer: A Randomized Controlled Trial.

Postoperative impaired sleep quality and pain are associated with adverse outcomes. Stellate ganglion block (SGB) has shown promising results in enhancing sleep quality and alleviating neuropathic pain. This study aimed to investigate the effects of ultrasound-guided SGB on postoperative sleep quality and pain in patients undergoing breast cancer surgery. This study is a parallel-group randomized controlled clinical trial with two groups: SGB and control. Fifty female patients undergoing breast cancer surgery were randomized in a 1:1 ratio to receive preoperative ultrasound-guided single-injection SGB (SGB group) or just an ultrasound scan (control group). All participants were blinded to the group assignment. The primary outcome was postoperative sleep quality, assessed by the St. Mary's Hospital Sleep Questionnaire and actigraphy 2days postoperatively. The secondary outcome was postoperative pain, measured by thevisual analog scale. A total of 48 patients completed the study, with 23 patients in the control group and 25 in the SGB group. The postoperative St. Mary's Hospital Sleep Questionnaire scores were significantly higher in the SGB group than in the control group on 1day postoperative (30.88 ± 2.44 versus 27.35 ± 4.12 points, P = 0.001). The SGB also increased the total sleep time and sleep efficiency (main actigraphy indicators) during the first two postoperative nights. Compared with the control group, preoperative SGB reduced postoperative pain and the incidence of breast cancer-related lymphedema (20% versus 52.2%, P = 0.02, odds ratio 0.229, 95% confidence interval 0.064-0.821). There were no adverse events related to SGB. Preoperative ultrasound-guided SGB improves postoperative sleep quality and analgesia in patients undergoing breast cancer surgery. SGB may be a safe and practical treatment to enhance the postoperative quality of life in patients with breast cancer. The study was registered in the Chinese Clinical Trial Registry (ChiCTR2100046620, principal investigator: Kai Zeng, date of registration: 23 May 2021).

Influence of nursing care intervention on quality of sleep in hospitalized patients at Riyadh, Saudi Arabia

Background: In clinical practice, patients' sleep is disrupted by medical professionals' care or evaluations both at night and during the day. Multiple factors contribute to this sleep disruption resulting in poor clinical outcomes. Aims: This study aims to determine the quality of sleep perceived by patients admitted to various hospital settings, as well as the factors affecting sleep quality. Settings and Design: Descriptive explorative design involving purposive convenient sampling of 90 hospitalized admitted at King Khalid General Hospital, Al Majmaah, and General Hospital, Zulfi. Methodology: St. Mary's Hospital Sleep Questionnaire used to assess patients' sleep and sleep-disturbing scale. Statistical Analysis Used: The Chi-square test was used to compare the different parameters related to sleep. Results: Subjective conclusions suggested that 38 (26.4%) patients slept lightly, 67 (46.5%) were moderately satisfied with their last night's sleep, and only 9 (6.3%) were mildly dissatisfied. Continuous light, uncomfortable Pillow, strange fragrances (P = 0.004), hearing frequent sound (P = 0.018), telephone (P = 0.046), and machine alarms (P = 0.006) were the elements impacting sleep pattern connected to the patient themselves. Tubings, monitor leads, pain, and fear of death all significantly influenced sleep pattern. Many of the healthcare workers' behaviors such as awakening by doctors and nurses (χ 2 = 13.08, P = 0.02), making loud noise (χ 2 = 15.85, P = 0.007), assessing vitals (χ 2 = 12.90, P = 0.02), hygiene care (χ 2 = 5.24, P = 0.14), feeding (χ 2 = 9.82, P = 0.09), tubing and drain (χ 2 = 17.92, P &lt; 0.002), and suctioning (χ 2 = 21.30, P = 0.0001) had significant influence on sleep pattern. Conclusion: Based on the results, nurses can minimize the factors that cause sleep interference in hospitalized patients and avoid the possible negative effects caused by sleep deprivation.

The efficacy and safety of intravenous chlorpromazine treatment for sleep disturbance in patients with incurable cancer, with oral administration difficulty: a 1-week, prospective observational study.

Sleep disturbance is a common psychiatric disorder in patients with cancer. However, many patients with incurable cancer have difficulty receiving oral administrations, which limits treatment options during disease progression. The aim of the present study was to assess the efficacy and safety of intravenous chlorpromazine treatment for sleep disturbances in patients with incurable cancer, with oral administration difficulty. A prospective observational study was conducted among 52 patients with incurable cancer, with oral administration difficulty received daily intravenous chlorpromazine treatment for sleep disturbance from 2018 to 2020 at a single-unit university hospital. St. Mary's Hospital Sleep Questionnaire (SMHSQ) compared sleep before and after intravenous chlorpromazine administration. The primary endpoint was the efficacy rate of sleep quality [defined as a score of ≥4 (range, 1-6)] 7 days after receiving chlorpromazine. Beginning the day after receiving chlorpromazine, sleep quality significantly improved from a mean score of 1.6±0.7 to 4.3±1.2, and 80.8% [95% confidence interval (CI): 66.5-89.1%] and 69.2% (95% CI: 53.8-79.6%) of patients reported good sleep quality 3 and 7 days after receiving chlorpromazine, respectively. The patients reported increased total sleep time and fewer awakenings during sleep, and satisfaction with sleep and difficulty falling asleep improved. Some adverse events occurred [akathisia (n=2), dry mouth (n=2), and somnolence (n=3)]; all were Grade 1 (CTCAE ver5.0) and improved with chlorpromazine discontinuation. Systolic blood pressure and heart rate displayed no clinically problematic changes. Intravenous chlorpromazine has a high tolerability and effectively treats sleep disturbances in patients with incurable cancer with oral administration difficulties.

Sleep time differs among people who co-use cocaine and cannabis compared to people who only use cocaine

ObjectivePeople who use cocaine experience numerous sleep problems and often use cannabis to mitigate these problems. However, co-using cocaine and cannabis may result in worse sleep outcomes when compared to using cocaine only. The current study examined group differences in subjective sleep outcomes among people who use cocaine and people who co-use cocaine and cannabis. MethodsParticipants were 82 individuals with cocaine use disorder who were enrolled in a randomized clinical trial for cocaine treatment. Sleep outcomes, assessed at baseline prior to treatment, were measured with the Saint Mary's Hospital Sleep Questionnaire and included total sleep time, perceived sleep quality, difficulty falling asleep, and daytime alertness. Analysis of covariance and Kruskal-Wallis tests were used to compare sleep outcomes between participants with urine samples that tested positive for both cocaine and cannabis at baseline, those who tested positive for cocaine only, and those who tested negative for all drugs. ResultsTotal reported sleep time was highest among those with a drug negative urine, followed by those with a cocaine positive urine and those who tested positive for cocaine and cannabis. There were no differences in perceived sleep quality, difficulty falling asleep, or daytime alertness between groups. ConclusionsPeople who co-use cocaine and cannabis may report reduced sleep time relative to those who only use cocaine. Co-use of cannabis may exacerbate sleep difficulties in people who use cocaine by decreasing total sleep time, although it is important to note that the groups each reported similar sleep quality. Implications for treatment and directions for future research are discussed.

Effect of rosa damascene aromatherapy on anxiety and sleep quality in cardiac patients: A randomized controlled trial

IntroductionAnxiety and sleep disorders are the most common disorders of patients admitted to the cardiac care units. The purpose of this study is to investigate the effect of Rosa damascene fragrance on anxiety and sleep quality of hospitalized patients in the cardiac care units. MethodsIn this Randomized clinical trial, 60 patients who had the inclusion criteria were conveniently sampled and randomly allocated to the experimental and control groups. Patients were enrolled in the study 24 h after hospitalization. Those diagnosed with dysrhythmia, ACS, and CHF were included. Patient recruitment lasted from October 2018 to December 2019. In these groups, in addition to the routine care, the intervention was performed for three consecutive nights from 22:00 to 06:00. In the experimental group, patients inhaled five drops of Rosa damascene essence 40% in distilled water, while in the control group, patients inhaled five drops of distilled water as placebo. In both groups, anxiety and sleep quality were examined before and after three consecutive nights using the St. Mary's Hospital Sleep Quality Questionnaire (SMHSQ) and the Spiel Berger State-Trait Anxiety Inventory (STAI) questionnaire. ResultsThe results of this study showed that the use of Rosa damascene aroma in patients hospitalized in the cardiac care unit significantly reduces anxiety and increases the improvement of sleep quality in the experimental group compared to the control group (P < 0.05). The significance level for anxiety and sleep quality was (P = 0.001). ConclusionAromatherapy with Rosa damascene reduces anxiety and increases the sleep quality of patients hospitalized in the cardiac care unit. Therefore, along with other treatment measures, Rosa damascene can be used as a complementary method to reduce anxiety and improve sleep quality.

Effect of Guided Imagery Along With Breathing Relaxation on Sleep Quality of the Elderly Patients Under Abdominal Surgery: A Randomized Clinical Trial.

Elderly patients undergoing surgery often suffer from sleep disorder. Holistic therapies might help them sleep better. The aim of this research was to determine the effect of guided imagery along with breathing relaxation on sleep quality in elderly patients undergoing abdominal surgery. A double-blind randomized clinical trial was conducted on 90 elderly patients undergoing abdominal surgery in 2 educational hospitals in 2018, Mashhad, Iran. The elderly patients with different abdominal surgical procedures were distributed to the wardrooms and then the rooms were randomly assigned into 2 groups. In the intervention group, the patients learned breathing relaxation the day before surgery and then an audiotape was provided to perform the guided imagery from the day before surgery for 5 days (twice) along with breathing relaxation. St Mary's Hospital Sleep Inventory was completed the night before, 48 hours and 96 hours after the surgery. Data analysis was done using SPSS 21 through analytical tests. Results of the test indicated that the score of sleep quality was significantly higher in the intervention group the night before surgery (P = .001). The total scores of sleep quality in the intervention group 48 and 96 hours after the surgery were significantly higher (P < .001). Based on results of generalized estimating equation model, the score of sleep quality for patients was 8.76 units higher in the intervention group than in the control group by controlling for the effects of time. Guided imagery along with breathing relaxation improved the sleep quality of the elderly patients undergoing abdominal surgery.Trial registration: IRCT20180731040652N1.

Pediatric psycho-oncology in Russia: Caregiver mental health and sleep outcomes on the oncology wards.

Caregivers are at risk of poor sleep and elevated distress during their child's cancer treatment. Russia is currently underrepresented in the international psycho-oncology field, with no identified psychosocial standards of care, and limited or inconsistent psychological service provision, particularly for caregivers. This study aimed to determine the prevalence of Russian caregivers' psychological distress and identify factors associated with caregiver sleep duration when staying on the pediatric oncology ward. We recruited 74 caregivers of children with cancer and 74 comparison caregivers in Rostov-on-Don, Russia. Participants completed a survey assessing clinical outcomes, sleep (St Mary's Hospital Sleep Questionnaire), and psychological distress (Depression Anxiety Stress Scales-21 [DASS-21]). Caregivers of children with cancer reported significantly higher scores for all DASS-21 subscales and higher depression (48.6% vs. 24.6%), anxiety (47.3% vs. 12.3%), and stress (45.9% vs. 0%) scores from "moderate" to "extremely severe." Caregivers of children with cancer reported significantly shorter sleep duration (5.82 vs. 7.49 h, t[143] = -6.22, p = 0.002), more night-time awakenings (3.20 vs. 1.25, t[135] = 6.94, p < 0.001) and worse sleep quality (46.5% vs. 9.6%; x2 [1] = 24.4, p < 0.001) than comparison caregivers. Caregivers with a higher total DASS-21 score (B = -1.32, p = 0.032) and those who were closer to diagnosis (B = -1.53, p = 0.012) reported shorter sleep duration. Russian caregivers of children with cancer experience high rates of psychological distress and poor sleep on the oncology ward. These findings provide an important target for future research and culturally relevant clinical interventions to improve caregivers' mental health and capacity for care.

The effect of foot reflexology massage on burn-specific pain anxiety and sleep quality and quantity of patients hospitalized in the burn intensive care unit (ICU)

BackgroundBurn-specific pain anxiety and sleep disorders are common factors in burned patients that affect wound healing process, as well as the severity of burn pain. This study aimed to investigate the effect of foot reflexology massage on burn-specific pain anxiety and sleep condition of patients hospitalized in the burn ICU. MethodIn this randomized controlled clinical trial, 52 patients were assigned by permuted block randomization 1:1 to the intervention (n=26) and control (n=26) groups. The intervention group received 20min of foot reflexology massage during 3 days on their third, fourth and fifth days of hospitalization and 15min before changing wound dressings. Patients in the control group merely received routine care. The Burn-Specific Pain Anxiety Scale (BSPAS) was completed for three consecutive days before and after changing wound dressings, and St. Mary's Hospital Sleep Questionnaire (SMHSQ) was filled out for four consecutive days before changing wound dressings for patients in both groups. The data were analyzed by IBM SPSS 16 software, Chicago, independent t, Chi-square, Friedman, Mann–Whitney and Wilcoxon tests. FindingsWe found no significant difference between pain-anxiety in the two groups before the intervention. The trend of different days in each groups were compared with Friedman test and showed that pain anxiety (p<0.001), sleep latency (p<0.001), duration of the last day's sleep (p<0.001) and satisfaction of the last night sleep (p<0.001) had a significant difference. In addition, Mann–Whitney test results showed that there were significant differences between the two groups at different times in terms of the above variables (p<0.05). The effect size was=0.82 for pain anxiety between group after the intervention. ConclusionBased on the results, foot reflexology massage can effectively reduce pain anxiety levels and improve sleep quality and quantity of patients with burn injuries; therefore, this non- pharmacological therapeutic method is recommended to be used in the burn ICUs. (Clinical trial’s registration code: IRCT20110906007494N27)

A comparative study on the effects of aromatherapy with orange and Citrus aurantium extracts on sleep quality in patients with acute coronary syndrome

Introduction: Patients with heart disease suffer from sleep disorders due to the disease process. Aromatherapy is one of the ways to treat sleep disorders. The aim of this study was to compare the effect of aromatherapy with orange and citrus aurantium on sleep quality in patients with acute coronary syndrome. Materials and Methods: This clinical trial study was performed on 120 patients admitted to selected hospitals of Shahid Beheshti University of Medical Sciences (Tehran, Iran) in 2019. The samples were randomly divided into four groups of aromatherapy with Orange extract, Citrus aurantium extract, Orange-Citrus aurantium extract and the control. The control group received only routine care. Data collection tools included St. Mary's Hospital Sleep Quality Questionnaire and demographic profile form. Results: The mean sleep time in the Citrus aurantium group (6.5 ± 0.3 hours), the orange group (8 ± 0.7 hours) and the Orange-Citrus aurantium group (8 ± 0.8 hours) was significantly higher than the control group (5.4 ± 0.4 hours) (p=0.000). The mean score of sleep quality in the orange, Citrus aurantium and Orange-Citrus aurantium groups was significantly better than the control group (p=0.0008). The sleep quality score in the combined aromatherapy group was significantly higher than each group alone (P<0.05). No significant differences were found in the sleep quality between Orange and Citrus aurantium groups. Conclusion: Aromatherapy with the combined Orange and Citrus aurantium extracts and each extract alone has a positive effect on sleep quality and can be used as a complementary measure in nursing care. © 2020, Semnan University of Medical Sciences.

The effect of Benson’s relaxation response on sleep quality and anorexia in cancer patients undergoing chemotherapy: A randomized controlled trial

Background and objectivesPatients with cancer experience many side effects due to its nature and usual treatments. Sleep disorders and anorexia are the most commonly reported symptoms in cancer patients undergoing chemotherapy. The present study aimed to investigate the effect of Benson's Relaxation Response (BRR) on sleep quality and anorexia in cancer patients undergoing chemotherapy. Methodology and participantsIn the present clinical trial, a total of 84 patients were enrolled and randomly divided into two groups of experimental and control. Benson's relaxation response was administered to the experimental group twice a day over 5 consecutive days. Data was collected using St. Mary's Hospital Sleep Questionnaire (SMHSQ) and anorexia questionnaire with Visual Analog Scale (VAS). ResultsThe results of our study showed a significant improvement in the sleep quality in the experimental group at 24 (p = 0.02) and 48 (p = 0.001) hours after the intervention compared to the control group. Benson's relaxation response (BRR) also had a significant effect on the anorexia in the experimental group at 24 (7.5 ± 1.6) and 48 (6.9 ± 2.1) hours after the intervention compared to the control group. No side effects were reported during the study and follow-up period. ConclusionBenson's relaxation response as a complementary method may improve sleep quality and anorexia in cancer patients undergoing chemotherapy. Further studies with greater sample size and longer follow-up period are needed to confirm the current findings.

The Effects of Deep-Breathing Exercises on Postoperative Sleep Duration and Quality in Patients Undergoing Coronary Artery Bypass Graft (CABG): a Randomized Clinical Trial.

Introduction: Disordered sleep occurs frequently in patients who have undergone coronary bypass graft surgery, and it contributes to increased morbidity, mortality, and resource utilization. The present study aimed to determine the effects of deep-breathing exercises on postoperative sleep duration and quality in patients undergoing coronary artery bypass graft.Methods: This study was a clinical trial. The study sample included 64 patients who were coronary artery bypass graft hospitalized from January 2015 to April 2015 in Qazvin Booali-Sina hospital. The patients were selected by convenient sampling and then the participants were randomly allocated to the intervention and control groups. The baseline and postoperative (day 7) sleep duration and quality metrics were measured. The St Mary's Hospital Sleep Questionnaire was used to evaluate sleep quality in two groups.Results: Baseline night sleep duration was 5.72 (1.63) hours in the control group and 5.58 (1.07) hours in the intervention group. The initial findings showed that the mean of sleep quality score of patients in the intervention and control groups were 19.72 (2.68) and 18.22 (3.81) respectively. These measurements did not decline postoperatively in the intervention group while night sleep duration and quality declined in the control group. Deep breathing exercise program had a significant effect on sleep quality score in the intervention group compared to the control group.Conclusion: The results indicated that deep breathing exercises prevent decline in sleep quality postoperatively. It seems to be a safe method with no side effects for these patients. Furthermore, it is a simple method to implement and does not impose a high cost.

The Effect of Warm Footbath on the Quality of Sleep on Patients with Acute Coronary Syndrome in Cardiac Care Unit.

Introduction: This study aimed to determine the effect of warm footbath before bedtime on the quality of sleep on patients with acute Coronary Syndrome in Cardiac Care Unit.Methods: This study was conducted on 120 patients admitted to CCU at Mazandaran Heart Center and randomly divided into two groups of intervention and control. In the intervention group, warm footbath was performed after the second night in hospital before bed time by 41 C water for 20 minutes for three consecutive nights; in contrast, the control group did not receive anything of this sort. The next day, St Mary's Hospital Sleep Questionnaire was completed to evaluate sleep quality. Then, the obtained data were analyzed using SPSS software and Friedman, Wilcoxon exact statistical tests.Results: The quality of sleep in the first night of hospitalization was different from the third night after the intervention in both groups and the improvement process of sleep quality was observed in both groups. Most patients had moderate impairments (23-36), which had not changed during the intervention. In intervention groups, 8 patients had severe sleep disorders (greater than 37), which declined to 1 after three nights of intervention. While, in the control group this number fell from 10 patients with severe sleep disorders to 5. Warm footbath had a great positive impact on patients suffering from severe sleep disorders (P<0.05).Conclusion: Although warm footbath did not improve the quality of sleep in all patients, it reduced the number of patients who had severe sleep disturbances.

Richards-Campbell sleep questionnaire: psychometric properties of Chinese critically ill patients.

Sleep abnormalities occur frequently in critically ill patients. Nurses are strategically placed, specifically in intensive care units, to promote sleep in such patients. Currently, an effective sleep assessment tool in Chinese is not available for intensive care settings. This study aimed to assess the reliability and validity of the Chinese version of the Richards-Campbell Sleep Questionnaire (RCSQ-C). It also aimed to evaluate patient-nurse reliability and agreement of the RCSQ-C in the intensive care unit (ICU). We translated the original RCSQ into Chinese and then back-translated it into English to ensure its accuracy of translation. Internal consistency, discrimination validity and construct validity of the RCSQ-C were examined in 150 critically ill patients. The convergent validity of the RCSQ-C was evaluated in 44 of 150 critically ill patients, and data from the RCSQ-C were compared with those of the Chinese version of St Mary's Hospital Sleep Questionnaire (SMHSQ). Comparisons were also made between RCSQ-C scores obtained from patients and their nurses. Cronbach's α of the RCSQ-C was 0.923; thus, it showed high reliability. The corrected item-total correlation coefficient was in the range of 0·680∼0·805, which showed that the items were homogeneous for evaluating sleep. The content validity was 0·84. One factor was extracted with a cumulative contribution rate of 76·597%. Confirmatory factor analysis showed that the original single-factor structure proposed by Richards adequately fit the data. The RCSQ-C could discriminate poor and good sleepers, which supported discriminant validity. There was a close correlation between the scores obtained from the RCSQ patient's version and those from the SMHSQ. The intraclass correlation coefficients of the patient and nurse ranged from 0·315 to 0·609. The psychometric properties of the RCSQ-C suggest its utility in critically ill patients. Patient-nurse reliability on the RCSQ-C was "fair" to "substantial", with nurses tending to overestimate patients' perceived sleep quality. If the validity of this questionnaire is supported in other ICU samples, RCSQ-C could be used as a routine evaluation instrument to distinguish good and poor sleepers and then direct nurses to form corresponding treatment plans to promote sleep.

Three nights leg thermal therapy could improve sleep quality in patients with chronic heart failure.

Sleep quality is often impaired in patients with chronic heart failure (HF), which may worsen their quality of life and even prognosis. Leg thermal therapy (LTT), topical leg warming, has been shown to improve endothelial function, oxidative stress, and cardiac function in patients with HF. However, its short-term influence to sleep quality has not been evaluated in HF patients. Eighteen of 23 patients with stable HF received LTT (15min of warming at 45°C and 30min of insulation) at bedtime for 3 consecutive nights and 5 patients served as control. Subjective sleep quality was evaluated by St. Mary's Hospital Sleep Questionnaire, Oguri-Shirakawa-Azumi Sleep Inventory, and Epworth sleepiness scale, and also objectively evaluated by polysomnography. LTT significantly improved subjective sleep quality indicated by depth of sleep (p<0.01), sleep duration (p<0.05), number of awaking (p<0.01), nap duration (p<0.01), sleep quality (p<0.05), and sleep satisfaction (p<0.05). It was also objectively affirmed by a slight but significant decrease of sleep stage N1 (p<0.01), and increase in sleep stage N2 (p<0.05). No significant changes occurred in the controls. Hence, the short-term LTT could improve subjective and objective sleep quality in patients with HF. LTT can be a complimentary therapy to improve sleep quality in these patients.

The Effect of Lavender Extract on Sleep Quality in Patients Undergoing Angiography Admitted to Cardiac Care Unit

Inadequate sleep quality is one of the most common problems in patients admitted to Cardiac care units (CCUs). Therefore, this research aimed to investigate with the effect of lavender essential oil in sleep quality in candidates for angiography who were hospitalized in an CCU in Iran. This randomized clinical trial was conducted in 60 patients undergoing angiography who were hospitalized in the CCU of a hospital in Ilam City, Iran. Patients were randomly assigned 1:1 to either a case group or a control group (each group, n = 30). Data were collected using the St. Mary's Hospital Sleep Questionnaire, which was completed before and after the intervention. The case group received 15 drops of lavender essential oil 24 hours prior to angiography and every 8 hours thereafter; the control group received its previous routine care. After the intervention, the data were analyzed via descriptive and inferential statistical tests using SPSS statistical software v19. The demographic characteristics of the case and control groups were similar (P>0.05). There was no statistically significant difference before the intervention in sleep quality between the case group and the control group (P>0.05). Additionally, no statistically significant difference was observed in the case or the control group with respect to sleep quality before and after the intervention (P>0.05). Due to the lack of effect shown by lavender essential oil in sleep quality, further studies should be conducted to the effects of lavender and other essential oils.

Valuation of Sleep Quality and Related Factors In Hospitalized Elderly People in Shahid Beheshti Hospital of Kashan

Introduction and purpose: Hospitalizations can affect the sleep quality in the elderly. A variety of of factors contribute in sleep quality changes. The aim of this study was to evaluate sleep quality and its associated factors in hospitalized elderly patients in hospital. Materials and Methods: This cross-sectional study was conducted in 2015. 200 elderly martyr Beheshti hospital were selected by available sampling to be.St. Mary's hospital sleep quality questionnaire (SMHSQ), respectively.
