NCT07389954
Many patients report dreams during intravenous (IV) propofol sedation, but it is uncertain whether listening to music changes how often dreams occur or how pleasant they feel. This single-center randomized study compared three auditory conditions during propofol sedation for elective surgery under spinal anesthesia or peripheral nerve block: (1) patient-selected preferred music, (2) matched non-preferred music, and (3) silence (headphones only). Music or silence was delivered through identical closed-back headphones starting 1-2 minutes before sedation and continuing until the end of sedation. The main outcomes were (1) whether a dream occurred (yes/no) assessed by a neutral modified Brice interview in the post-anesthesia care unit (PACU), and (2) dream pleasantness rated on a 0-10 scale among participants who reported a dream. Additional outcomes included coded dream content features, patient satisfaction, sedative dose, hemodynamic variability, early recovery measures, postoperative symptoms, and adverse events.

The objective of this study is to evaluate the effect of adding dexmedetomidine on evoked potentials in adult patients undergoing spinal surgery under intravenous anesthesia
NCT07259291
Remifentanil is commonly used as an opioid during general anesthesia. In recent years, several pharmacokinetic/pharmacodynamic (PK/PD) models for target-controlled infusion (TCI) have been developed, with the Eleveld model being one of the most recent and designed for broad applicability. The aim of this study is to compare the Eleveld TCI model with the routinely used Minto model, in order to evaluate potential differences in the predicted effect-site concentrations (CeR) required to achieve equivalent analgesia levels, as measured by qNOX (CONOX monitor) and the Analgesia Nociception Index (ANI). Post-Tetanic Count (PTC) was also assessed during the maintenance phase to investigate possible differences in nociceptive index responses between the two TCI models.
NCT07239687
This prospective observational study aims to compare the clinical performance of two target-controlled infusion (TCI) models, Eleveld and Schnider, for propofol sedation in mechanically ventilated intensive care unit (ICU) patients. The study evaluates sedation depth, hemodynamic stability, and recovery profiles using the Bispectral Index (BIS) and Riker Sedation-Agitation Scale. Secondary outcomes include awakening time, total propofol dose, and incidence of delirium after sedation withdrawal. The findings may help identify the most reliable pharmacokinetic model for safe and effective ICU sedation.

NCT06862245
Propofol has significant hemodynamic side effects. It is a lipophilic agent and is generally used at a dose of 2-2.5 mg/kg for induction. In patients with a body mass index (BMI) greater than 25, it can lead to serious complications. This patient group often has comorbidities such as hypertension, coronary artery disease, left ventricular hypertrophy, stroke, and obstructive sleep apnea. Hemodynamic profile changes are influenced by both the rate of propofol administration and the total dose. Therefore, it is necessary to investigate the appropriate dose and infusion rate of propofol during anesthesia induction. The primary aim of this study is to compare the effects of propofol induction doses, determined based on total body weight and lean body weight (calculated using tomography), on anesthesia depth using BIS and SedLine monitoring in patients with BMI \>25. The secondary aim of the study is to compare propofol induction doses calculated using two different methods in terms of: * Mean arterial pressure (MAP), * Frequency of hypotension (MAP \<65), * Frequency of Trendelenburg position or vasopressor requirement and their response, * Tachycardia (heart rate \>100 bpm), * Frequency of hypertension (SBP \>140). Additionally, the sensitivity and delay rates of BIS and SedLine monitoring in determining anesthesia depth were compared. A total of 120 patients undergoing general anesthesia for urological surgeries at our hospital were included in the study. Patients were randomized into two groups (Group T/Group L). All patients were taken to the operating room, and in addition to routine monitoring, BIS and SedLine monitoring were provided. All patients received 1 mcg/kg of fentanyl. * Group T received propofol at a dose of 2-2.5 mg/kg based on total body weight. * Group L received propofol at a dose of 2-2.5 mg/kg based on lean body weight, which was calculated from CT imaging by a radiologist. * Propofol was administered at a rate of 100 mg/min. The laryngeal mask will be placed once an adequate depth of anesthesia is achieved. All data were recorded at 2-minute intervals for 6 minutes before and after induction. The collected data were statistically analyzed for comparison.

NCT06716840
Intensive care medicine is vital in managing patients after cardiac surgery with endotracheal intubation，in order to provide extensive monitoring to assure clinical stabilization. During this time of recovery, sedation is frequently employed. However, prolonged sedation risks negative sequelae.At present,propofol, benzodiazepines, and dexmedetomidine are typical drugs used for sedation of patients in intensive care unit.Each has its own advantages and disadvantages.The investigators try to find near-ideal agents for sedation,characterized by good sedative effect,minimal adverse effects and rapid awakening facilitating earlier extubation.Remimazolam appeared to be an effective and safe sedative for short term sedation. Study participants were predicated on age (\> 18 years), admission following cardiac surgery, still mechanical ventilation within 48 hours,and prior informed consent.Participants were randomized to receive remimazolam besylate or propofol in a 1:1 ratio for sedation with a target sedation depth before extubation.Finally，the investigators will compare the sedation effect and safety between the 2 groups ，to prove if remimazolam is appropriate for sedation in patients after cardiac surgery in intensive care unit.

Perioperative anesthesia can affect postoperative cognitive function. In our previous study, intraoperative dexmedetomidine (Dex) infusion reduced the incidence of delirium within the first 5 days after brain tumor. However, the mechanism is still unclear. With the development of neuroimaging, multimodal neuroimaging technology provide a new method to explore the underlying mechanism. Therefore, the purpose of this study is to analyze the alterations of brain network under sedation and anesthesia by different anesthetics in patients with supratentorial glioma and their association with cognition.
NCT06775366
This study want to observe the effects of remimazolam and propofol for general anesthesia on postoperative rhythm and cognitive function. The observation group was given remimazolam for general anesthesia, and the control group was given propofol for general anesthesia. Both drugs are commonly used as intravenous anesthetics for general anesthesia and have been shown to be safe for use in general anesthesia. The investigators hope can understand the effects of remimazolam and propofol for general anesthesia on rhythm status and cognitive function through this study, further reduce the occurrence of postoperative cognitive function impairment, and enable subjects to better recover.

Dental pain and anxiety are quite common in pediatric patients. However, due to children's inability to express their fears and lack of knowledge about the procedures to be performed, these symptoms have often been misunderstood and inadequately treated in pediatric settings. Children have consistently experienced high rates of emergence anxiety during the recovery process after general anesthesia. Emergence anxiety can be harmful to the patient, leading to bleeding at the surgical site, displacement of intravenous catheters, parental anxiety, additional care needs, and delays in hospital discharge. Inhalation anesthetics are preferred for pediatric surgeries because they promote faster recovery. However, inhalation anesthetics often lead to a high rate of emergence anxiety, ranging from 25% to 80% depending on the scoring scale used, the child's age, and the type of surgery performed. Additional sedative or analgesic drugs, such as midazolam, dexmedetomidine, or propofol, have been used to prevent emergence anxiety. Dexmedetomidine is a selective α2-agonist with sedative and analgesic effects, but it can cause mild respiratory depression. Numerous studies have shown that intranasal dexmedetomidine is more effective than other adjunctive drugs. It has been found to be beneficial in reducing emergence anxiety during pediatric anesthesia with minimal blood pressure or respiratory depression. However, although intranasal dexmedetomidine initially has relatively rapid absorption, the absorption process may take longer compared to intravenous administration, implying that the child's hemodynamic status is more stable and a longer effective absorption time may have a clinical advantage in preventing emergence anxiety. The aim of this study is to compare and investigate the effectiveness of nasal dexmedetomidine and intravenous propofol applications used to reduce agitation in pediatric cases following extubation in clinical practice.
NCT06729892
The propofol-remifentanil closed-loop TCI system based on EEG guidance has been clinically verified, which enables more precise anesthetic dosing. As an adjunct to anesthesia, esketamine has been shown to stabilize hemodynamics, reduce opioid use, and reduce postoperative nausea and vomiting. However, due to its specific electroencephalographic excitatory effect, esketmine's clinical use in close-loop system has been limited. The aim of this experiment was to determine the specific impact of esketamine on EEG and thus obtain a new EEG baseline for close-loop system, which can broaden the application of close-loop TCI system in combination with other drugs.

NCT06386965
Stress is defined as hormonal and metabolic changes in the biological system that follow any injury. The stress response occurs as a general systemic response to injury and includes a wide range of endocrinological, immunological and hematological effects. The level of stress in the surgical process can affect not only the patients outcome but also the overall health system. The two main agents used in maintenance for general anesthesia are inhalation and intravenous anesthetics. Both inhalation anesthesia and TIVA (Total Intravenous Anesthesia) approaches provide general anesthesia suitable for surgical operations. However, the mechanisms of action of these two methods differ and are not fully understood. The aim of investigators' for this study was to investigate the effect of different anesthetic agents on stress inflammatory response in the preoperative, peroperative and postoperative periods.
NCT06522711
The goal of this clinical trial is to learn if virtual reality can reduce propofol requirements in adult, female patients undergoing elective breast surgery under regional anesthesia. The main question it aims to answer is: Can virtual reality immersion reduce intra-operative propofol requirements in adult female patients undergoing elective breast surgery under regional anesthesia? Researchers will compare time and weight-adjusted average propofol requirements in both the intervention group and the control group to see if there is a reduction in sedative usage in the group using the virtual reality device. Participants will be randomly assigned to either a virtual reality (intervention) group or a control group. * The patients in the virtual reality group will have a virtual reality headset on during the surgery with a preselected scenario of their choice. * Both groups will have access to patient-controlled sedation under the supervision of an anesthesiologist and will be permitted to self-administer propofol boluses as needed.
