By integrating pharmacokinetic parameters, adverse drug reactions (ADRs), and clinical complications, the study will analyze variations in sufentanil kinetics under different body composition conditions. Under the guidance of research personnel, participants will undergo non-invasive body composition assessment using the nBody S10 analyzer. Key metrics collected will include, but are not limited to, mineral content, muscle mass, lean body mass (LBM), total body weight, and body fat percentage (BFP).

The elderly patients have poorer overall conditions and have lower tolerance to trauma, anesthesia, and surgery. Therefore, the incidence of postoperative complications is relatively higher. In non-cardiac surgeries, approximately 20% of elderly patients experience postoperative complications, and the incidence of postoperative delirium (POD) is 23.8%. This may lead to prolonged hospital stays, increased hospital costs, and affect prognosis and even mortality. The investigators plan to conduct a prospective cohort study by systematically collecting biological samples and clinical information of elderly patients during the perioperative period to explore the possible risk factors and pathogenesis of postoperative delirium and postoperative complications in elderly surgical patients, and to construct a risk prediction model for postoperative complications.

Researchers hypothesized that Bifidobacterium breve Supplement could reduce the progression rate of idiopathic scoliosis in children and potentially prevent the occurrence of new cases of scoliosis.

This is a prospective observational study involving adult patients with severe infection who are admitted to the intensive care unit (ICU). Severe infection and sepsis are major causes of death worldwide. Many patients experience uncontrolled inflammation or immune suppression, but current tests are limited in identifying which patients are at highest risk. This study focuses on specialized pro-resolving mediators (SPMs), a group of naturally occurring lipid molecules that help the body turn off inflammation and promote healing. Blood samples that are collected during routine clinical care will be used to measure levels of SPMs. No additional blood draws or experimental treatments will be performed. The purpose of this study is to understand how SPM levels change over time in patients with severe infection and how these changes relate to organ function and outcomes such as survival. By combining SPM measurements with routine laboratory results, immune cell counts, and imaging findings, the study aims to identify different clinical phenotypes and to develop tools that may help doctors recognize high-risk patients earlier in the future. All participants will receive standard medical care determined by their treating physicians. No experimental drugs or interventions are given as part of this study.

The goal of this observational study is to learn how changes in immune cells are linked to outcomes in adults with severe infection who are treated in the intensive care unit (ICU). Severe infections, including sepsis, can affect how the immune system works and may lead to poor recovery or death. Researchers want to better understand these immune changes so that people at higher risk can be identified earlier. The main questions this study aims to answer are: Are certain immune cell patterns linked to survival or death within 28 days? Are these immune patterns linked to organ failure or longer stays in the ICU? Participants will be adults with severe infection who are admitted to the ICU as part of their routine medical care. This study does not change or add to their medical treatment. Participants will: Have small blood samples collected at several time points during their ICU stay Allow researchers to review their medical records, including test results and outcomes Researchers will analyze immune cells in the blood and relate these findings to clinical outcomes. The results may help improve future risk assessment and understanding of immune changes in people with severe infection.

Emergence delirium (ED) stands out as a prevalent postoperative complication among paediatric patients, correlating with extended hospitalization periods, escalated healthcare expenses, and increased incidence of postoperative maladaptive behaviours (POMBs). There is a lack of well-established pharmacological or non-pharmacological interventions demonstrating efficacy in reducing the occurrence of ED. Therefore, our objective is to assess the potential of family-centred perioperative care for anaesthesia (FPCA) in mitigating the incidence of ED in children, compared with routine anaesthesia.

For pediatric patients undergoing general anesthesia, poor anesthesia induction compliance often has adverse effects on individual behavior in the early postoperative period. Dexmedetomidine can reduce the cardiovascular responses and postoperative mental adverse reactions caused by esketamine anesthesia induction \[6\]. This study aims to explore the ED50 and ED95 and clinical effects of the combination of dexmedetomidine and esketamine nasal drops for preoperative sedation in children of different ages undergoing general anesthesia, providing a theoretical basis for the combined use of dexmedetomidine and esketamine for preoperative sedation in children undergoing general anesthesia.

The goal of this study is to conduct analyses the changes of cell growth factors, inflammatory factors, metabolites, plasma proteome, etc. in the blood of patients with ACS (acute coronary syndrome), as well as their correlations with the disease prognosis, based on multi-omics or other related research methods. The main questions it aims to answer are: The growth factors that have significant changes in the peripheral blood of the ACS population, especially fibroblast growth factors? Inflammatory factors and chemokines related to the onset of ACS? The metabolites and proteins that are significantly altered in the peripheral blood after the onset of ACS? Researchers will compare ACS population to CCS (Chronic Coronary Syndrome) population, and control group (patients without coronary artery stenosis, valvular heart disease, structural heart disease, or any other kind of cardiomyopathy).The peripheral venous blood from the participants will be collected within 24 hours after their admission to the hospital.

Hypothermia is a common complication in pediatric anesthesia. Hypothermia will prolong the recovery time of anesthesia, and may also lead to increased oxygen consumption, prolonged blood coagulation time, and affect the metabolism of anesthetic drugs and postoperative immune function. Sevoflurane is the most commonly used inhaled anesthetic in children. This study explored the effect of sevoflurane on the sweat threshold of pediatric patients and analyzed the characteristics of body temperature regulation in children of different ages under anesthesia, which will help to understand the mechanism of body temperature regulation in children under anesthesia, and also provide a scientific basis for clinical anesthesia temperature management.

To observe and study the clinical effect of Huperzine A Injection on reducing postoperative delirium in elderly patients undergoing non-cardiac surgery

General anesthesia is the preferred choice for pediatric patients, but the induction of volatile anesthetics via face mask may cause preoperative anxiety and postoperative delirium. Total intravenous anesthesia (TIVA) is more suitable for pediatric patients, as it can effectively alleviate preoperative anxiety, reduce the risk of postoperative delirium and mania, shorten hospital stay, reduce medical burden, and increase parental satisfaction. Propofol, although effective for anesthesia, has drawbacks such as injection pain and respiratory and circulatory suppression. Remimazolam is a novel ultra-short-acting benzodiazepine drug, which has no injection pain, minimal impact on respiration and circulation, and rapid onset and elimination, making it suitable for children. However, research on remimazolam in children is limited. This study aims to compare the effect of propofol and remimazolam intravenous anesthesia combined with regional or caudal block on respiratory depression in preschoolers.

The effect of Remimazolam on brain electrical activity. Previous studies have shown that in healthy male volunteers, EEG changes during Remimazolam infusion are characterized by an initial increase in the beta band and a later increase in the delta band. When monitoring the depth of anesthesia, the commonly used Bispectral Index in clinical practice was originally developed for propofol. Therefore, studies have shown that the correlation between the depth of sedation of benzodiazepines such as midazolam and Bispectral Index is weak. In contrast, the beta wave ratio is considered a more suitable EEG indicator for monitoring the sedative effect of Remimazolam. The above indicates that Remimazolam has a specific pattern of influence on EEG activity, especially in the regulation of anesthesia depth, with unique characteristics.

Sevoflurane is one of the most commonly used volatile anesthetics in children because of its rapid induction, recovery and recovery properties. Clinical studies using noninvasive brain monitoring have shown that general anesthetics and hypnotics generate electroencephalogram (EEG) oscillations in specific spatial tissues that are fundamentally related to the structure and function of neural circuits. Slow-wave-delta (0.1-4 Hz) oscillations were present in children of all ages, and the advantage of frontal α-wave oscillations appeared at approximately 6 months, began to be consistent at 10 months, and persisted at older ages. Another study, which analyzed EEG under sevoflurane general anesthesia in children aged 0-6 months, found that Theta and alpha wave power decreased with a decrease in sevoflurane concentrations in infants between 4 and 6 months of recovery. However, these studies lack detailed characterization of the neural circuit activity associated with anesthesia, especially at specific developmental ages that are highly correlated with brain plasticity. The aim of this study was to explore electroencephalogram (EEG) of children of different ages under sevoflurane general anesthesia (including anesthesia induction, maintenance and recovery) . By analyzing these EEG data in detail, we hope to be able to better understand the EEG characteristics of children of different ages under sevoflurane anesthesia, and thus develop a neurophysiology pediatric anesthesia status monitoring strategy.
