RESUMEN
BACKGROUND: Postoperative sleep disturbance has a potentially detrimental effect on postoperative recovery. Perioperative patients are affected by several factors. General anesthesia induces a non-physiological state that does not resemble natural sleep. Exposure to propofol/sevoflurane can lead to desynchronization of the circadian rhythm, which may result in postoperative sleep disturbance characterized by mid-cycle advancement of sleep and daytime sleepiness. Dexmedetomidine is a highly selective α2-adrenoceptor agonist with a unique sedative effect that facilitates the transition from sleep to wakefulness. Basic research has shown that dexmedetomidine induces deep sedation, similar to physical sleep, and helps maintain forebrain connectivity, which is likely to reduce delirium after surgery. The aim of this study is to evaluate the influence of exposure to the mono-anesthetic propofol on the development of postoperative sleep disturbance in young and middle-aged female patients undergoing hysteroscopy and whether prophylactic administration of dexmedetomidine influences reducing postoperative sleep disturbance. METHODS: This prospective randomized controlled trial (RCT) will include 150 patients undergoing hysteroscopy at the First Affiliated Hospital of Xiamen University. Participants will be randomly assigned to three groups in a 1:1:1 ratio. The dexmedetomidine group will have two subgroups and will receive a nasal spray of 0.2 µg/kg or 0.5 µg/kg 25 min before surgery, while the control group will receive a saline nasal spray. Three groups will undergo hysteroscopy with propofol-based TIVA according to the same scheme. Sleep quality will be measured using a wearable device and double-blind sleep assessments will be performed before surgery and 1, 3, and 7 days after surgery. SPSS 2.0 is used for statistical analysis. A χ2 test is used to compare groups, and t-test is used to determine statistical the significance of continuous variables. DISCUSSION: The purpose of this study is to investigate the incidence of propofol-associated sleep disorders and to test a combination of dexmedetomidine anesthesia regimen for the prevention of postoperative sleep disorders. This study will help to improve patients' postoperative satisfaction and provide a new strategy for comfortable perioperative medical treatment. TRIAL REGISTRATION: ClinicalTrials.gov NCT06281561.

Cardiovascular diseases are the leading cause of death among urban and rural residents and have become a major global public health problem. The prevention and control of cardiovascular disease risk factors is crucial for preventing, stabilizing, and even reversing cardiovascular disease. Studies have found that certain sleep disorders are directly related to cardiovascular disease and may be induced through pathways such as endothelial dysfunction, dysregulation of autonomic homeostasis, inflammatory response, and metabolic dysfunction. Exercise helps improve sleep disorders and thus reduce the risk of cardiovascular disease, and has irreplaceable advantages over pharmacological treatments for improving sleep. Different types of sleep disorders should be adjusted by factors such as exercise mode, intensity, and duration of exercise. A good sleep state further reduces the risk of cardiovascular disease. Discussing the effect of exercise on the improvement of the risk of cardiovascular disease associated with sleep disorders, and elaborating the mechanism of action of exercise in reducing the risk of cardiovascular disease from the perspective of sleep, can lay a foundation for the treatment of sleep disorders by exercise and propose new directions for reducing cardiovascular disease risk.

As people age, their sleep patterns and needs naturally change in response to developmental and health-related factors. However, attaining sufficient restorative sleep remains crucial for overall well-being in older adults. This manuscript provides an overview of common sleep alterations that tend to emerge with advancing age, such as shifts in circadian rhythms, decreases in deeper sleep stages, fragmented sleep architecture and an association between comorbidities and sleep disruption. Practical recommendations that target environmental, behavioral and lifestyle modifications may optimize sleep initiation, maintenance, and duration for the older population. By enhancing understanding of the sleep changes that occur in the aged population, geriatric nurses are better able to provide respectful, patient-centered care to older adults that are experiencing sleep difficulties.

Sleep disorders are one of the most common acute reactions on the plateau, which can cause serious complications. However, there is no effective and safe treatment currently available. Nimodipine (NMD) is a dihydropyridine calcium channel blocker with neuroprotective and vasodilating activity, mainly used for the treatment of ischemic brain injury. Commercial oral or injectable NMD formulations are not a good option for central neuron diseases due to their poor brain delivery. In this study, nimodipine dissolving microneedles (NDMNs) were prepared for the prevention of sleep disorders caused by hypoxia. NDMNs were composed of NMD and polyvinyl pyrrolidone (PVP) K90 with a conical morphology and high rigidity. After administration of NDMNs on the back neck of mice, the concentration of NMD in the brain was significantly higher than that of oral medication as was confirmed by the fluorescent imaging on mouse models. NDMNs enhanced cognitive function, alleviated oxidative stress, and improved the sleep quality of mice with high-altitude sleep disorders. The blockage of calcium ion overloading may be an important modulation mechanism. NDMNs are a promising and user-friendly formulation for the prevention of high-altitude sleep disorders.

OBJECTIVE: This review aims to evaluate the effectiveness of preventive parental education on infant sleep problems, delivered from pregnancy to 1 month postpartum, on infant sleep, postpartum parental sleep, and depression. INTRODUCTION: Infant sleep problems are likely to persist into childhood if not treated and are associated with difficulties in later development. Parents of children with sleep problems had lower sleep quality and emotional regulation than those without sleep problems. Chronic sleep deprivation and fragmentation increases the risk of maternal depression. Therefore, preventive parental education regarding infant sleep problems can improve the long-term well-being of both children and their parents. INCLUSION CRITERIA: Experimental and quasi-experimental study designs, including preventive parental education about infant sleep problems delivered from pregnancy to 1 month postpartum, will be considered. The outcomes will be infants' sleep, postpartum parental sleep, and parental depression. METHODS: MEDLINE (Ovid), CINAHL (EBSCOhost), PsycINFO (Ovid), the Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi (Japan Medical Abstracts Society) will be searched without restrictions on language or date of publication. Eligible studies will be critically appraised, and data will be extracted by 2 independent reviewers using the JBI methodology. The studies will be pooled for statistical meta-analysis. Where statistical pooling is not possible, the findings will be presented in narrative format. We will use the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to assess the certainty in the quality of evidence. REVIEW REGISTRATION: PROSPERO CRD42023430562.

Background: Perioperative sleep disorders exert a severe adverse impact on postoperative recovery. Recently, some observational studies reported that acupuncture-point stimulation (APS) provided benefits for promoting perioperative sleep quality. However, the effects of APS on perioperative sleep disorders following general anesthesia have not been thoroughly assessed by any systematic study and meta-analysis. Therefore, we conducted this systematic review and meta-analysis to reveal the effects of APS on perioperative sleep disorders. Methods: Eight databases (Chinese: CNKI, VIP, CBM, and Wanfang; English: PubMed, Embase, Web of Science, and Cochrane Library) were thoroughly searched to find randomized controlled trials (RCTs) that indicated a link between APS and the occurrence of perioperative sleep disorders. We applied RevMan 5.4 (Cochrane Collaboration) and Stata 16.0 (Stata Corp) to conduct our meta-analysis. In addition, the trial sequential analysis (TSA) tool was utilized to estimate the validity and reliability of the data. Results: In this study, nine RCTs with 719 patients were conducted. Compared to the control group, APS significantly improved perioperative subjective sleep quality (SMD: -1.36; 95% CI: -1.71 to -1.01; P < 0.00001). Besides, it increased perioperative TST (preoperative period MD = 24.29, 95% CI: 6.4 to 42.18, P = 0.0008; postoperative period MD = 45.86, 95% CI: 30.00 to 61.71, P < 0.00001) and SE (preoperative MD = 3.62, 95% CI: 2.84 to 4.39, P < 0.00001; postoperative MD = 6.43, 95% CI: 0.95 to 11.73, P < 0.00001). The consequence of trial sequential analysis further confirmed the reliability of our meta-analysis results. Conclusion: According to the currently available evidence, APS could effectively improve perioperative sleep quality and play an essential role in decreasing the incidence of perioperative sleep disorders.

BACKGROUND: Hypertensive patients are likelier to have cognitive function decline (CFD). This study aimed to explore physical activity level, sleep disorders, and type of work that influenced intervention effects on cognitive function decline in hypertensive patients and to establish a decision tree model to analyze their predictive significance on the incidence of CFD in hypertensive patients. METHODS: This cross-sectional study recruited patients with essential hypertension from several hospitals in Shandong Province from May 2022 to December 2022. Subject exclusion criteria included individuals diagnosed with congestive heart failure, valvular heart disease, cardiac surgery, hepatic and renal dysfunction, and malignancy. Recruitment is through multiple channels such as hospital medical and surgical outpatient clinics, wards, and health examination centers. Cognitive function was assessed using the Mini-Mental State Examination (MMSE), and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Moreover, we obtained information on the patients' type of work through a questionnaire and their level of physical activity through the International Physical Activity Questionnaire (IPAQ). RESULTS: The logistic regression analysis results indicate that sleep disorder is a significant risk factor for CFD in hypertension patients(OR:1.85, 95%CI:[1.16,2.94]), mental workers(OR:0.12, 95%CI: [0.04,0.37]) and those who perform both manual and mental workers(OR: 0.5, 95%CI: [0.29,0.86]) exhibit protective effects against CFD. Compared to low-intensity, moderate physical activity(OR: 0.53, 95%CI: [0.32,0.87]) and high-intensity physical activity(OR: 0.26, 95%CI: [0.12,0.58]) protects against CFD in hypertension patients. The importance of predictors in the decision tree model was ranked as follows: physical activity level (54%), type of work (27%), and sleep disorders (19%). The area under the ROC curves the decision tree model predicted was 0.72 [95% CI: 0.68 to 0.76]. CONCLUSION: Moderate and high-intensity physical activity may reduce the risk of developing CFD in hypertensive patients. Sleep disorders is a risk factor for CFD in hypertensive patients. Hypertensive patients who engage in mental work and high-intensity physical activity effectively mitigate the onset of CFD in hypertensive patients.

The global phenomenon of population aging presents a significant challenge, affecting both the increasing number of older individuals and their duration of living with disability. Tailored care services are crucial for improving the quality of life of older adults, particularly those with disabilities residing in nursing homes. However, ensuring personalized care and mitigating the risks associated with institutionalization are essential in optimizing care quality. One particular challenge in nursing homes is maintaining residents' personal routines and addressing sleep disturbances linked to neurodegenerative disorders. Non-pharmacological interventions are increasingly recognized as preventive and management strategies for behavioral and psychiatric symptoms in nursing home residents. Sleep disruptions, such as reduced duration and increased nocturnal awakenings, are prevalent among nursing home residents. Excessive nocturnal lighting and frequent caregiver interventions contribute to these disturbances. This study aimed to investigate the impact of implementing smart humancentric lighting on the sleep efficiency of nursing home residents. Data from pressure sensors embedded in mattresses were collected to assess sleep efficiency. The findings suggest that smart humancentric lighting can significantly reduce sleep disturbances and improve sleep quality in nursing home residents. Future research should delve into specific symptoms, care burden, and psychotropic agent utilization to validate the effectiveness of this intervention.

BACKGROUND: Dexamethasone is a cornerstone of paediatric acute lymphoblastic leukaemia (ALL) treatment, although it can induce serious side-effects. Our previous study suggests that children who suffer most from neurobehavioural side-effects might benefit from physiological hydrocortisone in addition to dexamethasone treatment. This study aimed to validate this finding. METHODS: Our phase three, double-blind, randomised controlled trial with cross-over design included ALL patients (3-18 years) during medium-risk maintenance therapy in a national tertiary hospital between 17th May 2018 and 5th August 2020. A baseline measurement before and after a 5-day dexamethasone course was performed, whereafter 52 patients with clinically relevant neurobehavioural problems were randomised to receive an intervention during four subsequent dexamethasone courses. The intervention consisted of two courses hydrocortisone (physiological dose 10 mg/m2/d in circadian rhythm), followed by two courses placebo, or vice versa. Neurobehavioural problems were assessed before and after each course using the parent-reported Strengths and Difficulties Questionnaire (SDQ) as primary end-point. Secondary end-points were sleep problems, health-related quality of life (HRQoL), hunger feeling, and parental stress, measured with questionnaires and actigraphy. A generalised mixed model was estimated to study the intervention effect. RESULTS: The median age was 5.5 years (range 3.0-18.8) and 61.5% were boys. The SDQ filled in by 51 primary caregivers showed no difference between hydrocortisone and placebo in reducing dexamethasone-induced neurobehavioral problems (estimated effect -2.05 (95% confidence interval (CI) -6.00-1.90). Also, no benefit from hydrocortisone compared to placebo was found for reducing sleep problems, hunger, parental stress or improving HRQoL. CONCLUSIONS: Hydrocortisone, when compared to placebo, had no additional effect in reducing clinically relevant dexamethasone-induced neurobehavioural problems. Therefore, hydrocortisone is not advised as standard of care for children with ALL who experience dexamethasone-induced neurobehavioural problems.

The quality of sleep, a key physiological factor that regulates information, memory, decision making, and other vital brain functions, can affect important physiological functions of the human body. According to disease classification systems, sleep disorders can be categorized into more than 90 types, including sleep apnea, insomnia, and hypersomnia. It may cause a variety of adverse consequences, such as depression, anxiety and other emotional disorders, as well as physical diseases such as hypertension, diabetes and stroke. In addition, the relevant cardiovascular and cerebrovascular diseases and cognitive impairment not only harm physical health, but also are associated with workplace accidents and safety problems, constituting public safety hazards. Sleep disorders have become a major social and scientific problem that impacts on the national economy and the livelihood of the people. Research on sleep disorders should be given more attention by researchers and policy makers. Herein, we mainly discussed the latest findings and difficulties concerning research on the prevention and intervention of sleep disorders and proposed strategies and suggestions accordingly.

OBJECTIVE: This single-arm pilot study was designed to generate pilot data on the use of a cooling mattress pad system on vasomotor symptoms (VMS; hot flashes and/or night sweats), self-assessed sleep, and daily hot flash interference among perimenopausal and postmenopausal women. METHODS: A total of 15 perimenopausal and postmenopausal women aged 45 to 59 years experiencing four or more VMS per day were recruited from the community. After completion of baseline questionnaires and a 2-week daily diary to confirm VMS eligibility, all women received a cooling mattress pad system to use at night for 8 weeks, during which time they continued to complete their daily diaries to record VMS frequency and severity. The primary study outcome was change from baseline in VMS frequency. Secondary outcomes were sleep quality, measured by the Pittsburgh Sleep Quality Index, and hot flash interference with daily life, assessed by the Hot Flash Related Daily Interference Scale, where higher sores indicate worse sleep quality and higher interference, respectively. We used repeated-measures methods (analysis of covariance, paired t tests, and McNemar test) to evaluate outcomes. RESULTS: VMS frequency significantly declined by 52% at 8 weeks ( P < 0.0001). Mean total Pittsburgh Sleep Quality Index score significantly declined 3.27 points from 11.14 at baseline to 7.87 at follow-up ( P = 0.011). The total Hot Flash Related Daily Interference Scale score significantly declined from 4.16 at baseline to 1.92 at follow-up ( P = 0.011). CONCLUSIONS: Women who used a cooling mattress pad system experienced significant and clinically meaningful reductions in VMS frequency, sleep disturbance, and hot flash interference with daily activities over an 8-week period. These results provide preliminary evidence suggesting that a cooling mattress pad used while sleeping can provide a nonpharmacological option to reduce VMS and sleep disturbance for women experiencing menopausal hot flashes.

AIM: Parents and professionals receive conflicting recommendations about management of infant sleep problems. The aim of this umbrella review was to provide an overview of summarised research on the prevention and treatment of sleep problems in infants (0-1 year), content of the interventions and the conditions under which they are delivered. METHODS: The umbrella review included five systematic reviews of 24 individual studies, mainly randomised controlled trials. Searches were conducted in PsycINFO, Cochrane, Campbell, Epistemonikos, PDQ-Evidence, IN SUM and the Norwegian Institute of Public Health, for reviews published during 2010-2021. RESULTS: The systematic reviews showed that behavioural interventions increased sleep in infants and parents. Interventions entailed reducing parental disturbances during sleep onset and enabling the infant to fall asleep and maintain sleep on their own. Knowledge about infant sleep and the establishment of positive bedtime routines seemed crucial for preventing and treating sleep difficulties. The interventions can be delivered in a few sessions, typically one-on-one during the postnatal period. CONCLUSION: Behavioural interventions can be recommended and adapted to the individual family. Positive outcomes for the infant and the family depend on a close and coordinated collaboration between child health clinics, community psychologists, general physicians and other services.

Postoperative sleep disorder frequently occurs in patients after surgery. Sleep disturbance aggravates pain, anxiety, and delirium, which is an important risk factor for poor recovery. Circadian rhythm disorder induced by general anesthesia plays important role in postoperative sleep disorders. A large number of clinical studies have shown that various forms and duration of general anesthesia can lead to postoperative sleep disorders. In this study, the effect of prolonged propofol anesthesia on biological rhythm was comprehensively evaluated by wireless physiological telemetry system, and the therapeutic effect of exogenous melatonin pretreatment was further investigated. The results showed that prolonged propofol anesthesia had significant impacts on the circadian rhythm of sleep, body temperature, locomotor activity and endogenous melatonin secretion within 24 h following anesthesia, resulting in diminished oscillation amplitude. In hypothalamus, the expression of circadian factor PER and CRY were inhibited by propofol, possibly through activation of CAMK-CREB signaling pathway. Post-translational factors GSK-3ß, SIRT1, AMPK were also involved in the regulation of circadian factors after propofol anesthesia. Melatonin pretreatment could restore circadian rhythm process by regulating circadian factor expression through post-translational modulation and prohibit the over-synthesis of melatonin in pineal gland. This study verified the effects of anesthetics on circadian rhythm and further evaluated the potential therapeutic effect of melatonin on postoperative circadian rhythm and sleep disorders.

The increasing prevalence of sleep disorders among university students should be taken seriously. Group counseling involving a mindfulness-based strategy may help prevent students from developing insomnia and subsequent mental health disorders. This study aimed to evaluate the ameliorating effects of a mindfulness-based group intervention on sleep problems and emotional symptoms in university students in China. Twenty-one university students (16 females, 22.71 ± 4.28 years) who were not on medication were recruited and assigned to the intervention group based on the criterion of high levels of sleep problems. Additionally, twenty-four university students (19 females, 24.50 ± 0.93 years) were included as a nonrandomized control group. Individuals in the intervention group participated in a two-hour group intervention once a week for eight sessions. All participants completed self-reported questionnaire baseline tests, postintervention tests, and one-month follow-ups on mindfulness, sleep quality, anxiety and depressive symptoms. Repeated-measures ANOVA was performed. The results revealed significant intervention effects, with significant differences observed between the two groups in mindfulness and sleep quality. However, there was no significant effect of the intervention on anxiety and depressive symptoms. This study contributes to a better understanding of the effectiveness of mindfulness-based intervention in addressing sleep problems in university students.

AIMS: Many studies have reported that the production of Lactobacillus brevis is beneficial for sleep, but the underlying mechanism remains unclear. Other known beneficial effects of Lactobacillus brevis include improvement of anxious or depressive symptoms and better modulation of the autonomic nervous system, both of which impact sleep. In this study, we investigated whether the sleep benefit of Lactobacillus brevis was associated with the modulating effects on the autonomic nervous system and anxious/depressive symptoms. MAIN METHODS: Wistar-Kyoto rats were fed the production of Lactobacillus brevis (ProGA28) for the last 2 weeks of treatment before being exposed to case exchange (stress-induced insomnia paradigm). Waking, quiet sleep, and paradoxical sleep states were defined based on polysomnographic measurements. Autonomic functioning was assessed by heart rate variability (HRV). A combined behavioral test was used to evaluate anxiety-like or depressive-like behaviors after the following 2 days. KEY FINDINGS: In exposure to the dirty cage, the control group had significant prolongation of sleep latency, sleep loss during the first 2 h, and decreased parasympathetic activity and increased sympathetic activity during quiet sleep, which were significantly mitigated in the ProGA28 group. In behavioral tests, the ProGA28 group exhibited significantly less anxiety/depression-like motor responses in the elevated plus maze test, the forced swimming test, and the three-chamber social interaction test. Less initial sleep loss in the ProGA28 group was related to higher parasympathetic activity during quiet sleep, and shorter sleep latency in both groups was associated with longer time staying in the open arm in the elevated plus maze test. SIGNIFICANCE: These findings suggest that L. brevis ProGA28 can attenuate stress-related sleep disturbance, which may be associated with increased parasympathetic activity and decreased anxiety-like behaviors.

Objective: The high rate of relapse has become the primary obstacle of drug rehabilitation. In this study, we explored the relationship between sleep disorders and relapse inclination in substance users, as well as the potential mediating mechanisms and corresponding interventions. Methods: A total of 392 male substance users were recruited to complete the questionnaires on sleep disorders, quality of life and relapse inclination. On account of this, 60 participants with sleep disorders were randomly screened and allocated to the intervention and control groups. The former received 12 weeks of Health Qigong aimed at treating sleep disorders, whereas the latter performed their regular production work. Results: Sleep disorders had a positive effect on relapse inclination, quality of life was a potential mediator of this relationship, and 12-week Health Qigong designed to treat sleep disorders improved not only their sleep quality but also their overall quality of life, which in turn reduce the tendency to relapse. Conclusion: Current research not only explores the high-risk factors influencing relapse, but also develops customized intervention strategies, which have theoretical and practical implications for decreasing relapse and increasing abstinence.

Opsins (also called animal rhodopsins) are universal photoreceptive proteins that provide the molecular basis of visual and nonvisual photoreception in animals, including humans. Opsins consist of seven helical α-transmembrane domains and use retinal, a derivative of vitamin A, as a chromophore. In many opsins, light absorption triggers photo-isomerization from 11-cis retinal to all-trans retinal, resulting in activation via dynamic structural changes in the protein moiety. Activated opsins stimulate cognate trimeric G proteins to induce signal transduction cascades in cells. Recently, molecular and physiological analyses of diverse opsins have progressively advanced. This review introduces the molecular basis and physiological functions of opsins. Based on the functions of opsins, I will discuss the potential of opsins as target molecules to treat and prevent visual and nonvisual diseases such as sleep disorder and depression.

Los trastornos del sueño son frecuentes en la población y una causa importante de morbilidad. El objetivo de esta revisión es evaluar las alteraciones del sueño en periodos de emergencia y desastres. A lo largo de la historia, la esfera biopsicosocial y el sueño de las personas ha sido abrumada por múltiples eventos a gran escala, tales como desastres naturales, tragedias provocadas por el hombre, conflictos bélicos, crisis sociales y pandemias, cuya experiencia puede derivar en problemas de salud a corto, mediano y/o largo plazo. En los estudios analizados, se ha observado el impacto negativo de las emergencias y desastres en el sueño, por lo que ha cobrado gran relevancia la difusión y promoción de medidas que incentiven el buen dormir. Debido a la llegada del COVID-19 y a la situación de confinamiento por periodos prolongados en el hogar para prevenir su propagación, han surgido importantes consecuencias a nivel social. Ciertos factores ocupacionales y características de los desastres se asocian a mayor comorbilidad, un alto riesgo de experimentar agotamiento físico, trastornos psicológicos e insomnio en grupos altamente vulnerables, como lo son los profesionales de la salud, rescatistas y socorristas. El insomnio es el trastorno de sueño más frecuente en la población general y su empeoramiento en el contexto de pandemia por COVID-19 representa un nuevo problema en salud pública. Es por ello, que es indispensable promover campañas de prevención de salud física y mental orientados a la pesquisa precoz y manejo de patologías de la esfera psicosocial, dentro de las posibilidades socioeconómicas.
Sleep disorders are common in the population and are major cause of morbidity. The objective of this review is to assess sleep disturbances in times of emergency and disasters. Throughout history, the biopsychosocial field and sleep have been affected by multiple large-scale events, such as natural disasters, man-caused tragedies, armed conflicts, social crises and pandemics, the experience of which can lead to short, medium and/or long term health problems. In several studies, the negative impact of emergencies and disasters on sleep have been analyzed, emphasizing the importance of the diffusion and promotion of measures that encourage good sleep. The arrival of COVID-19 and consequent home confinement for prolonged periods caused important social consequences. Certain occupational factors and characteristics of disasters are associated with greater comorbidity: a high risk of experiencing physical exhaustion, psychological disorders and insomnia, especially in highly vulnerable groups, such as health professionals, rescuers and first aids-responders. Insomnia is the most frequent sleep disorder in the general population and its worsening in the context of the COVID-19 pandemic, represents a new public health problem. It is essential to promote physical and mental health prevention campaigns, aimed at early screening and management of pathologies in the psychosocial sphere, within socioeconomic possibilities.

INTRODUCTION: The circadian rhythm of melatonin secretion is disturbed after general anaesthesia, leading to postoperative sleep disturbance. Small studies investigating the preventive effect of melatonin administration on postoperative sleep disturbance have not reached any conclusions. Therefore, we will conduct a systematic review and meta-analysis to obtain conclusive results. METHODS AND ANALYSIS: We prepared this protocol following the 2015 Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols guidelines. We will conduct a search for randomised controlled trials that evaluated the effect of melatonin and melatonin agonists on postoperative sleep quality in adult patients undergoing general anaesthesia or regional anaesthesia with sedation. We will exclude patients undergoing regional anaesthesia without sedation. Relevant studies will be searched in the following eight databases: MEDLINE, the Cochrane Central Register of Controlled Trials, Embase, Web of Science and four preregistration sites from inception to 1 January 2021. No language restrictions will be applied. Two authors will independently scan and select eligible studies and perform data extraction and assessment of the risk of bias. The Visual Analogue Scale scores for sleep quality will be combined as the mean difference with a 95% CI using a random-effect model; we will use I2 to assess heterogeneity. We will evaluate the quality of trials using the Cochrane methodology and assess the quality of evidence using the Grading of Recommendation Assessment, Development and Evaluation approach. If appropriate, trial sequential analysis will be performed. ETHICS AND DISSEMINATION: No ethical approval is required for this meta-analysis, as it does not include individual patient data. We will disseminate the results of this meta-analysis in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42020180167.
