Abstract
Background: Patients in the intensive care unit (ICU) often experience poor sleep quality. Pharmacologic sleep aids are frequently used as primary or adjunctive therapy to improve sleep, although their benefits in the ICU remain uncertain. This review aims to provide a comprehensive assessment of the objective and subjective effects of medications used for sleep in the ICU, as well as their adverse effects. Methods: PubMed, Web of Science, Scopus, Embase, and Cochrane Central Register of Controlled Trials were systematically searched from their inception until June 2023 for comparative studies assessing the effects of pharmacologic sleep aids on objective and subjective metrics of sleep. Results: Thirty-four studies with 3498 participants were included. Medications evaluated were melatonin, ramelteon, suvorexant, propofol, and dexmedetomidine. The majority of studies were randomized controlled trials. Melatonin and dexmedetomidine were the best studied agents. Objective sleep metrics included polysomnography (PSG), electroencephalography (EEG), bispectral index, and actigraphy. Subjective outcome measures included patient questionnaires and nursing observations. Evidence for melatonin as a sleep aid in the ICU was mixed but largely not supportive for improving sleep. Evidence for ramelteon, suvorexant, and propofol was too limited to offer definitive recommendations. Both objective and subjective data supported dexmedetomidine as an effective sleep aid in the ICU, with PSG/EEG in 303 ICU patients demonstrating increased sleep duration and efficiency, decreased arousal index, decreased percentage of stage N1 sleep, and increased absolute and percentage of stage N2 sleep. Mild bradycardia and hypotension were reported as side effects of dexmedetomidine, whereas the other medications were reported to be safe. Several ongoing studies have not yet been published, mostly on melatonin and dexmedetomidine. Conclusions: While definitive conclusions cannot be made for most medications, dexmedetomidine improved sleep quantity and quality in the ICU. These benefits need to be balanced with possible hemodynamic side effects.

Abstract
Anesthesia is critical to pediatric care, ensuring the safety and comfort of children undergoing medical procedures. With a growing interest in alternative anesthetic agents, melatonin has emerged as a promising candidate due to its sedative, analgesic, anti-inflammatory, and neuroprotective properties. This comprehensive review explores the potential applications of melatonin in pediatric anesthesia. We delve into the pharmacological characteristics of melatonin, its anesthetic properties, and its clinical applications in pediatric care, including preoperative sedation, adjunct to general anesthesia, postoperative pain management, and prevention of emergence delirium. Additionally, we discuss the safety profile of melatonin, potential adverse effects, and comparative analysis with traditional anesthetics. Finally, we highlight future research directions to provide insights into melatonin's role in pediatric anesthesia and its implications for clinical practice.

Pharmaceuticals (Basel) 2023; 17:37. [PMID: 38256871 PMCID: PMC10819646 DOI: 10.3390/ph17010037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 12/15/2023] [Accepted: 12/21/2023] [Indexed: 01/24/2024] Open
Abstract
Volatile anesthetics (VAs) are medicinal chemistry compounds commonly used to enable surgical procedures for patients who undergo painful treatments and can be partially or fully sedated, remaining in an unconscious state during the operation. The specific molecular mechanism of anesthesia is still an open issue, but scientific evidence supports the hypothesis of the involvement of both putative hydrophobic cavities in membrane receptors as binding pockets and interactions between anesthetics and cytoplasmic proteins. Previous studies demonstrated the binding of VAs to tubulin. Since actin is the other major component of the cytoskeleton, this study involves an investigation of its interactions with four major anesthetics: halothane, isoflurane, sevoflurane, and desflurane. Molecular docking was implemented using the Molecular Operating Environment (MOE) software (version 2022.02) and applied to a G-actin monomer, extrapolating the relative binding affinities and root-mean-square deviation (RMSD) values. A comparison with the F-actin was also made to assess if the generally accepted idea about the enhanced F-to-G-actin transformation during anesthesia is warranted. Overall, our results confirm the solvent-like behavior of anesthetics, as evidenced by Van der Waals interactions as well as the relevant hydrogen bonds formed in the case of isoflurane and sevoflurane. Also, a comparison of the interactions of anesthetics with tubulin was made. Finally, the short- and long-term effects of anesthetics are discussed for their possible impact on the occurrence of mental disorders.

Efficacy and Safety of Preoperative Melatonin for Women Undergoing Cesarean Section: A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Trials. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1065. [PMID: 37374268 PMCID: PMC10302920 DOI: 10.3390/medicina59061065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 05/26/2023] [Accepted: 05/27/2023] [Indexed: 06/29/2023]
Abstract
Background: Cesarean section (CS) has been linked to a number of negative effects, such as pain, anxiety, and sleeping problems. The aim of this systematic review and meta-analysis was to investigate the safety and efficacy of preoperative melatonin on postoperative outcomes in pregnant women who were scheduled for elective CS. Methods: We systemically searched 4 electronic databases (PubMed, Scopus, Web of Science, and Cochrane Library) from inception until 10 March 2023. We included randomized controlled trials (RCTs) comparing melatonin and placebo for postoperative outcomes in CS patients. For risk of bias assessment, we used the Cochrane Risk of Bias 2 tool. Continuous variables were pooled as mean difference (MD), and categorical variables were pooled as a risk ratio (RR) with a 95% confidence interval (CI). Results: We included 7 studies with a total of 754 pregnant women scheduled for CS. The melatonin group had a lower pain score (MD = -1.23, 95% CI [-1.94, -0.51], p < 0.001) and longer time to first analgesic request (MD = 60.41 min, 95% CI [45.47, 75.36], p < 0.001) than the placebo group. No difference was found regarding hemoglobin levels, heart rate, mean arterial pressure, total blood loss, or adverse events. Conclusions: Preoperative melatonin may reduce postoperative pain in CS patients without side effects. This research offers a safe and affordable pain management method for this population, which has clinical consequences. Further research is needed to validate these findings and determine the best melatonin dosage and timing.

Abstract
BACKGROUND Melatonin and dexmedetomidine have both been used as a premedication to decrease emergence delirium in children. The effectiveness of oral melatonin, compared with atomised intranasal dexmedetomidine, in this role is not well studied. OBJECTIVE To study the efficacy of pre-operative atomised intranasal dexmedetomidine versus oral melatonin in children scheduled for ophthalmic surgery under sevoflurane. DESIGN A prospective, randomised, double-blind trial. SETTING Ophthalmic surgery in a university teaching hospital, April 2021 to October 2021. PATIENTS A total of 120 children undergoing ophthalmic surgery with sevoflurane anaesthesia. INTERVENTION Children were randomised to receive pre-operative intranasal dexmedetomidine 2 μg/kg via an atomiser device (dexmedetomidine group) or oral melatonin 0.5 mg kg -1 (melatonin group), 45 min before surgery. OUTCOMES MEASURED The primary outcome was the incidence of emergence delirium assessed by the Paediatric Anaesthesia Emergence Delirium scale. Secondary outcomes included pre-operative sedation, quality of inhalational induction, postoperative sedation and pain. RESULTS The incidence of emergence delirium was lower in the dexmedetomidine group than in the melatonin group (17 versus 37%, relative risk 0.45, 95% CI: 0.24 to 0.88; P = 0.01). Children in the dexmedetomidine group were more sedated following premedication and in the postanaesthesia care unit ( P < 0.05). Postoperative pain scores were lower in the dexmedetomidine group than in the melatonin group: 0 [0 to 3] versus 2.5 [0-4], ( P = 0.01). The requirement for and dose of rescue fentanyl analgesia postoperatively was comparable between the two groups. CONCLUSION Atomised intranasal dexmedetomidine significantly reduced emergence delirium in paediatric opthalmic procedures under sevoflurane anaesthesia compared to oral melatonin.

Abstract
Background Despite advances in surgical and anesthesiology techniques, many patients continue to experience postoperative pain after lumbar disc surgeries. The aim of this study was to investigate the effect of preoperative oral melatonin on the severity of postoperative pain after lumbar laminectomy/discectomy. Methods In this double blinded randomized controlled clinical trial 80 patients undergoing an elective mini-open microdiscectomy surgery at Imam Khomeini educational hospital in Sari, Iran, were selected and randomly assigned into one of four groups. Patients in group A, B, C, and D received 3, 5 and 10 mg melatonin or placebo tablets one hour before surgery, respectively. Using the visual analogue scale (VAS) the severity of pain, nausea and vomiting, pruritus, and use of narcotics were assessed immediately after surgery and before leaving the post-anesthesia care unit, 6, 12 and 24 hours postoperatively. Results In all three groups receiving melatonin at all three different doses, postoperative pain was significantly less than the placebo group (P<0.01). There were no statistically significant differences in postoperative pain level between the three groups receiving melatonin (P>0.05). The amount of opioid received by the patients within 24 hours after surgery had statistically significant differences within the groups (P=0.043, F=2.58). The results of post hoc analysis in terms of postoperative pain intensity showed statistically significant differences between the two groups receiving melatonin at a dose of 5 mg and the placebo group (P=0.04). No serious side effects reported in four groups. Conclusion The use of oral melatonin with a dose of 5 mg, 1 hour before the surgery as an inexpensive method can effectively reduce pain intensity as well as the amount opioid use after lumbar laminectomy and discectomy.

Abstract
BACKGROUND Pre-operative anxiety is a risk factor for emergence delirium in children and a multimodal approach including sedatives and nonpharmacological measures is the current strategy to tackle this anxiety. The efficacy of oral melatonin as a component of multimodal anxiolytic strategy to decrease emergence delirium is not well studied. OBJECTIVE The aim of this study was to evaluate the efficacy of a multimodal anxiolytic strategy including oral melatonin or midazolam to decrease emergence delirium after sevoflurane anaesthesia. DESIGN A randomised, double-blind, parallel arm, placebo-controlled trial. SETTING Tertiary care teaching hospital from July 2019 till January 2020. PARTICIPANTS Children in the age group of 3 to 8 years who received sevoflurane anaesthesia for elective ambulatory procedures. INTERVENTIONS Children were randomised to receive oral premedication with either melatonin 0.3 mg kg-1, midazolam 0.3 mg kg-1 or honey as placebo. All the children received standardised nonpharmacological measures involving multiple techniques to allay anxiety. The anaesthetic plan was also standardised. MAIN OUTCOME MEASURES The primary outcome was the incidence of emergence delirium as assessed by the Watcha scale in the postanaesthesia care unit. The secondary outcomes were pre-operative anxiety assessed using a modified Yale Preoperative Anxiety scale, patient compliance with mask induction using the Induction Compliance Checklist and postoperative sedation. RESULTS Data from 132 children were analysed. Melatonin significantly reduced the incidence of emergence delirium compared to placebo: 27 vs. 50%, respectively, an absolute risk reduction of 23.3 [95% confidence interval 3.7 to 42.9), P = 0.03]. Melatonin also significantly reduced the risk of emergence delirium compared with midazolam: 27 vs. 56%, respectively, an absolute risk reduction of 29.2 (95% CI 9.5 to 48.8). The midazolam group had a similar incidence of emergence delirium as placebo. Sedation scores were similar in the three groups postoperatively. The incidence and score of pre-operative anxiety as well as the compliance with mask induction were similar in the three groups. CONCLUSIONS A multimodal anxiolytic approach including oral melatonin, as opposed to oral midazolam, significantly reduced emergence delirium after sevoflurane anaesthesia.

Abstract
Background Abolished circadian rhythm is associated with altered cognitive function, delirium, and as a result increased mortality in critically ill patients, especially in those who are mechanically ventilated. The causes are multifactorial, of which changes in circadian rhythmicity may play a role. Melatonin plays a crucial role as part of the circadian and sleep/wake cycle. Whether sedation effects circadian regulation is unknown. Hence, the objective of this study was to evaluate the melatonin concentration in critically ill patients randomized to sedation or non-sedation and to investigate the correlation with delirium. Methods All patients were included and randomized at the intensive care unit at the hospital of southwest Jutland, Denmark. Seventy-nine patients completed the study (41 sedated and 38 non-sedated). S-melatonin was measured 3 times per day, (03.00, 14.00, and 22.00), for 4 consecutive days in total, starting on the second day upon randomization/intubation. The study was conducted as a sub-study to the NON-SEDA study in which one hundred consecutive patients were randomized to sedation or non-sedation with a daily wake-up call (50 in each arm). Primary outcome: melatonin concentration in sedated vs. non-sedated patients (analyzed using linear regression). Secondary outcome: risk of developing delirium or non-medically induced (NMI) coma in sedated vs. non-sedated patients, assessed by CAM-ICU (Confusion Assessment Method for the Intensive Care Unit) analyzed using logistic regression. Results Melatonin concentration was suppressed in sedated patients compared to the non-sedated. All patients experienced an elevated peak melatonin level early on in the course of their critical illness (p = 0.01). The risk of delirium or coma (NMI) was significantly lower in the non-sedated group (OR 0.42 CI 0.27; 0.66 p < 0.0001). No significant relationship between delirium development and suppressed melatonin concentration was established in this study (OR 1.004 p = 0.29 95% CI 0.997; 1.010). Conclusion Melatonin concentration was suppressed in sedated, critically ill patients, when compared to non-sedated controls and the frequency of delirium was elevated in sedated patients.

Abstract
Background: Intracerebral hemorrhage (ICH) is one of the most debilitating kinds of stroke. Recent evidence shows that the proper initiation of neuroprotective agents might save at risk neurons and improve the outcome. Objectives: The focus of this study is to evaluate the neuroprotective effect of melatonin on patients with hemorrhagic stroke. Methods: Forty adult patients with confirmed nontraumatic ICH, who were admitted to the ICU within 24 hours of the stroke onset were enrolled in this study. Subjects in the melatonin group received 30 mg of melatonin every night for 5 consecutive nights. In order to evaluate the intensity of the neuronal injury, S100B was assessed once on day 1 and, day 5 post ICU admission. Additionally, the length of ICU stay, mortality, and the duration of mechanical ventilation were also recorded. Results: Forty patients completed the study. In both groups the plasma concentrations of S100B decreased after 5 days compared with their baseline values. However, this reduction was more significant in the melatonin compared to the control group (P-value < 0.05). The duration of mechanical ventilation and length of ICU stay was shorter in the melatonin group, and this difference was statistically significant for the length of ICU stay (P-value < 0.05), and marginally significant for the duration of mechanical ventilation (P-value = 0.065). The in-ICU mortality rate of the melatonin group was 15%, almost half of that of the control group (30%). However, this difference was not statistically significant. Conclusions: In conclusion, melatonin can be considered as a harmless and effective nueroprotective agent with some unique features which has made it an appropriate adjunctive medicine for critically ill intubated patients.

Abstract
The analgesic benefit of melatonin and vitamin C as primary or adjuvant agents has been reported in various studies; however, their analgesic effects in the treatment of postoperative pain remain unclear. Thus, we aimed to evaluate the effect of single preoperative dose of oral melatonin or vitamin C administration on postoperative analgesia. In this study, we recruited 165 adult patients undergoing elective major abdominal surgery under general anesthesia. Patients were randomly divided into three equal (n = 55) groups. One hour before surgery, patients received orally melatonin (6 mg) in group M, vitamin C (2 g) in group C, or a placebo tablet in group P. Pain, sedation, patient satisfaction, total morphine consumption from a patient-controlled analgesia device, supplemental analgesic requirement, and the incidence of nausea and vomiting were recorded throughout 24 h after surgery. The mean pain score and total morphine consumption were found significantly lower in both M and C groups compared with group P (p < 0.001). There were no significant differences between group M and C with respect to pain scores (p = 0.117) and total morphine consumption (p = 0.090). Patients requested less supplemental analgesic and experienced less nausea and vomiting in groups M and C compared with group P. In conclusion, preoperative oral administration of 6 mg melatonin or 2 g vitamin C led to a reduction in pain scores, total morphine consumption, supplemental analgesic requirement, and the incidence of nausea and vomiting compared with placebo.

Abstract
Melatonin is involved in regulation of a variety of physiologic functions, including circadian rhythm, reproduction, mood, and immune function. Exogenous melatonin has demonstrated many clinical effects. Numerous clinical studies have documented improved sleep quality following administration of exogenous melatonin. Recent studies also demonstrate the analgesic, anxiolytic, antiinflammatory, and antioxidative effects of melatonin. This article reviews the principal properties of melatonin and how these could find clinical applications in care of the critically ill patients.

Abstract
OBJECTIVE Higher serum melatonin levels have previously been found in patients with severe sepsis who died within 30 days of diagnosis than in survivors. The objective of our study were to determine whether serum melatonin levels during the first seven days of severe sepsis diagnosis could be associated with sepsis severity and mortality. METHODS Multicentre study in eight Spanish Intensive Care Units which enrolled 308 patients with severe sepsis. We determined serum levels of melatonin, malondialdehyde (as biomarker of lipid peroxidation) and tumor necrosis factor-alpha at days 1, 4 and 8 of severe sepsis diagnosis. The study's primary endpoint was 30-day mortality. RESULTS A total of 103 patients had died and 205 survived at 30 days of severe sepsis diagnosis, with the non-survivors presenting higher serum melatonin levels at days 1 (p<0.001), 4 (p<0.001) and 8 (p<0.001) of severe sepsis diagnosis than the survivor patient group. The multiple logistic regression analysis found that serum melatonin levels at days 1, 4 and 8 of severe sepsis diagnosis (p<0.001, p=0.01 and p=0.001, respectively) were associated with mortality adjusted for age, serum lactic acid, SOFA score and diabetes mellitus. CONCLUSIONS The novel and more interesting findings of our study were that serum melatonin levels during the first seven days of severe sepsis diagnosis are associated with sepsis severity and mortality.

Abstract
Objective: Although mechanical ventilation is frequently a life-saving therapy, its use can result in unwanted side effects. It has been well documented that the choice of sedating agent may influence the duration of mechanical ventilation. Melatonin is a sedative and analgesic agent without any respiratory depressant effect which makes it an attractive adjuvant for sedation in the intubated patients. The aim of this study is to evaluate the effect of melatonin on the duration of mechanical ventilation in patients with hemorrhagic stroke. Methods: Forty adult intubated patients with hemorrhagic stroke, who were admitted to the Intensive Care Unit (ICU) within 24 h of onset, were enrolled in this randomized double-blind study. Subjects in the melatonin group received 30 mg of melatonin every night throughout the nasogastric tube. Length of ICU stay, mortality, and duration of mechanical ventilation were recorded for all patients. Findings: The duration of mechanical ventilation and length of ICU stay were shorter in patients who received melatonin in comparison with the control group, and this difference was statistically significant for the length of ICU stay and marginally significant for the duration of mechanical ventilation. Although not statistically significant, the mortality rate of the control group was 30%, almost double that of the study group (15%). Conclusion: Melatonin possesses hypnotic, analgesic, anti-inflammatory, and anti-oxidative properties that distinguish it as an attractive adjuvant in patients under mechanical ventilation. In conclusion, the administration of melatonin may facilitate the weaning process through decreasing the consumption of sedatives with respiratory depressant properties as well as preventing ventilator-associated lung injury.

Abstract
BACKGROUND AND AIMS Laryngoscopy and endotracheal intubation are considered as potent stimuli which lead to an increase in heart rate and blood pressure. Melatonin (N-acetyl-5-methoxytryptamine) has been studied for pre-operative anxiolysis and sedation in Intensive Care Unit. We made a hypothesis that melatonin can provide haemodynamic stability during laryngoscopy and intubation when given 120 min before the procedure. METHODS Sixty American Society of Anesthesiologists physical status Grade I and II patients of either gender, 20-45 years old, 40-65 kg body weight, scheduled to undergo elective surgical procedures under general anaesthesia were assigned into two equal groups - Group C (control) and Group M (melatonin). They received oral placebo or melatonin tablets 6 mg, respectively, 120 min before surgery. The haemodynamic parameters were recorded preoperatively, during laryngoscopy and endotracheal intubation and thereafter at 1, 3, 5 and 10 min. Unpaired t-test was used for between-group comparison of ratio and interval scale data. For within-group comparison of ratio and interval scale data, repeated-measures ANOVA and post hoc Bonferroni t-tests were used. RESULTS It was observed that in the control group, there was a significant increase in heart rate and blood pressure at laryngoscopy and intubation and persisted till 10 min post-intubation. In melatonin group, there was an insignificant increase in heart rate at the time of laryngoscopy and intubation which however settled within 1 min post-intubation. CONCLUSION Melatonin is an effective drug for attenuation of cardiovascular responses to laryngoscopy and endotracheal intubation.

Abstract
Background: The natural hormone melatonin has sleep inducing properties. Insomnia in cancer patients is common. So far, melatonin has been seldom tried for the improvement of sleep in patients with malignancies. Keeping this in mind, we planned and conducted a double-blind study to test the efficacy of melatonin in promoting sleep in patients with malignancies suffering from insomnia. Objective: To assess the hypnotic efficacy of oral melatonin in cancer patients with insomnia. Materials and Methods: After Ethical Committee approval, 50 patients (age range 20-65 years) from our pain clinic NIVARANE who met the Diagnostic and Statistical Manual of Mental Disorders 4th edition criteria for primary insomnia were randomized to receive melatonin 3 mg or placebo at 7 pm orally every day for 14 days from our pharmacist. After 1, 7, 14 days, the patients were reviewed with the Athens insomnia scale oral questionnaire to document the subjective sleep quality. The patients and we, the investigators were blinded to the study drug. Results: There were 2 drop outs (one from each group) as they failed to complete visit on day 14. Significant differences in favor of melatonin treatment were found in clinically relevant improvements in insomnia (46.53%; P = 0.00001 vs. 11.30%; P = 0.1026) There was improvement in sleep from 1 to 7 days (19.91%; P = 0.00001 vs. 0.98%; P = 0.2563). More significant improvements were seen between 7 and 14 days (33.24%; P = 0.00001 vs. 10.42%; P = 0.1469). Conclusion: We conclude that daily intake of oral melatonin 2 h before bedtime improves sleep induction and quality in cancer patients with insomnia.

Abstract
Chronic fluorosis is a widespread disease-related to the ingestion of high levels of fluoride through water and food. Prolonged ingestion of fluoride adversely affects the teeth, bones and other organs and alters their anatomy and physiology. Fluoride excess is a risk factor in cardiovascular disease and other major diseases, including hypothyroidism, diabetes and obesity. Although anaesthesiologists may be aware of its skeletal and dental manifestations, other systemic manifestations, some of which may impact anaesthetic management are relatively unknown. Keeping this in mind, the topic of chronic fluorosis was hand searched from textbooks, scientific journals and electronically through Google, PubMed and other scientific databases. This article concentrates on the effect of chronic fluorosis on various organ systems, its clinical features, diagnosis and the anaesthetic implications of the disease.

Abstract
AIM Melatonin has been proposed as a premedication alternative to midazolam, preceding anaesthesia induction. However, to our knowledge, data concerning interaction between melatonin and intravenous anaesthetic drugs in children are not available. The aim of this prospective, randomized, double-blind pilot study was to investigate the possible effect of melatonin premedication, in comparison to midazolam, on the required infusion of propofol in children undergoing surgery. As a secondary outcome, the effect of oral melatonin on the preoperative sedation level and on the post anaesthesia recovery score was evaluated. METHODS Children between the age of 5 and 14 years, scheduled for elective surgery, were prospectively enrolled between January 2012 and December 2013, and randomly assigned to two groups based on whether they received oral melatonin (0.5 mg/kg) or oral midazolam (0.5 mg/kg) premedication before induction of anaesthesia with propofol. Degree of sedation before and after anaesthesia was also evaluated. RESULTS Ninety-two patients were studied, 46 for each group. We found that oral administration of melatonin significantly reduced doses of propofol required for induction of anaesthesia in paediatric patients, more than midazolam (P < 0.001). No statistically significant differences were found in the pre- and post-anaesthesia sedation score (P = 0.387 and P = 0.525, respectively) between the two groups. CONCLUSIONS The present study demonstrates that melatonin enhances the potency of propofol also in paediatric patients. Moreover, considering the paediatric level of sedation, melatonin was equally as effective as midazolam. These data support the use of melatonin as a premedicant in paediatric surgical patients.

Abstract
Background and Aims: Melatonin (MT), a naturally occurring pituitary hormone has a sleep promoting effect. There are very few studies on pre-operative oral MT (0.2–0.5 mg/kg) in children. We planned a study to assess the efficacy of oral MT in two doses and compare it with oral midazolam and placebo for pre-operative anxiolysis, sedation, maintenance of cognition and psychomotor skills, parental separation behaviour and venepuncture compliance. Methods: This prospective double-blind randomised study was conducted after ethical committee approval on 100 children aged 5–15 years, American Society of Anaesthesiologists physical status I and II undergoing elective surgery at our hospital from January 1, 2014, to December 31, 2014. Mentally disordered children were excluded from the study. They were randomised into four groups of 25 each (A, B, C, D) to receive either oral MT 0.5 mg/kg or 0.75 mg/kg or oral midazolam 0.5 mg/kg or placebo 45–60 min, respectively, before induction. The child's anxiety, cognition and psychomotor function before and after pre-medication, behaviour during the parental separation and venepuncture were appropriately scored. Kruskal–Wallis analysis of variance for intergroup and Wilcoxon matched pairs tests for intragroup comparisons of data were applied. Results: The four groups were comparable regarding mean age, weight and sex. The anxiety score reductions in the three groups when compared to placebo were statistically significant. Children receiving MT 0.75 mg/kg had maximum anxiolysis and venepuncture compliance (P < 0.05). Cognition was decreased with maximum sedation, successful parental separation and psychomotor impairment in the midazolam group (P < 0.05). Conclusion: Oral MT (0.5 mg/kg and 0.75 mg/kg) in children decreases pre-operative anxiety without impairing cognitive and psychomotor functions, the 0.75 mg/kg dose being most effective.

Abstract
OBJECTIVE Melatonin in septic patients has been scarcely explored and only in studies of small sample size (maximum 20 patients). Thus, the objective of this study was to determine whether serum melatonin levels are associated with severity, oxidant and inflammatory state, and mortality in a large series of septic patients. METHODS A prospective, observational, multicenter study was performed in 6 Spanish intensive care units with 201 severe septic patients. Serum levels of melatonin were measured at moment of severe sepsis diagnosis. The end point was 30-day mortality. RESULTS Non-surviving patients (n = 71) showed higher serum melatonin levels (P < .001) than survivors (n = 130). Multiple logistic regression analysis showed that serum melatonin levels were associated with 30-day mortality (odds ratio, 1.022; 95% confidence interval, 1.001-1.043; P = .04), controlling for serum tumor necrosis factor-α levels, serum interleukin 6 levels and age. Serum melatonin levels were positively associated with serum levels of malondialdehyde as biomarker of oxidative stress, interleukin-6 and lactate, and with SOFA score. CONCLUSIONS The novel finding of our study was that serum melatonin levels are associated with mortality in septic patients.

Abstract
Sepsis is a systemic inflammatory response to infection. Sepsis, which can lead to severe sepsis, septic shock, and multiple organ dysfunction syndrome, is an important cause of mortality. Pathogenesis is extremely complex. In recent years, cell hypoxia caused by mitochondrial dysfunction has become a hot research field. Sepsis damages the structure and function of mitochondria, conversely, mitochondrial dysfunction aggravated sepsis. The treatment of sepsis lacks effective specific drugs. The aim of this paper is to undertake a narrative review of the current experimental treatment for mitochondrial dysfunction in sepsis. The search was conducted in PubMed databases and Web of Science databases from 1950 to January 2014. A total of 1,090 references were retrieved by the search, of which 121 researches met all the inclusion criteria were included. Articles on the relationship between sepsis and mitochondria, and drugs used for mitochondrial dysfunction in sepsis were reviewed retrospectively. The drugs were divided into four categories: (1) Drug related to mitochondrial matrix and respiratory chain, (2) drugs of mitochondrial antioxidant and free radical scavengers, (3) drugs related to mitochondrial membrane stability, (4) hormone therapy for septic mitochondria. In animal experiments, many drugs show good results. However, clinical research lacks. In future studies, the urgent need is to develop promising drugs in clinical trials.
