NCT07277881
This clinical trial aims to establish whether reversing remimazolam sedation with flumazenil can prevent postoperative neurocognitive disorders in patients undergoing total hip replacement surgery. The main questions it aims to answer are: * Does administering flumazenil after surgery lead to an improvement in cognitive function (measured by the MoCA scale) at 24 hours post-operation compared to a placebo? * Does this intervention reduce the incidence of postoperative delirium within the first 48 hours? Researchers will compare flumazenil to a placebo (0.9% saline solution) to see if actively reversing sedation leads to better cognitive outcomes and a lower incidence of delirium. Participants will: * Undergo a planned total hip replacement surgery under spinal anesthesia. * Receive sedation with remimazolam during the operation. * At the end of the surgery, receive an intravenous injection of the study drug (flumazenil) or a placebo. * Undergo assessments for cognitive function (using the MoCA scale) and delirium (using the 4AT scale) before and at multiple time points after the surgery. * Complete a questionnaire about their quality of recovery (QoR-15).
NCT07109362
Remimazolam is a novel ultra-short-acting benzodiazepine with extensive evidence supporting its safety and efficacy in clinical anesthesia and sedation. Its perioperative use in patients with glioma is becoming increasingly common. Glioma is the most common primary intracranial tumor and is often associated with neurocognitive impairment, with memory being the most frequently affected domain. Working memory, which integrates temporary storage and information processing, serves as a cognitive workspace. Currently, the impact of anesthetics on neurocognitive function during the perioperative period in glioma patients remains underexplored. This study aims to investigate the effects of remimazolam-induced mild sedation on working memory in healthy subjects and patients with supratentorial glioma by combining behavioral and electrophysiological measurements, focusing on the relationship with the P3b event-related potential amplitude. Furthermore, it explores how remimazolam sedation influences brain network functional connectivity during the encoding, maintenance, and retrieval phases of memory in healthy individuals and patients with supratentorial glioma.

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.
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.

The goal of this clinical trial is to compare the effect of sevoflurane and remimazolam on arterial oxygenation during one lung ventilation in patients undergoing video-assisted thoracoscopic surgery.
NCT05688345
A total of 120 patients (American Society of Anesthesiologist Physical Status 1-3) who signed a consent form among patients aged 19-80 years who are scheduled to undergo brachial plexus block and upper extremity surgery under monitored anesthetic care at our hospital were enrolled. Recruited patients are divided into three groups through computer-generated randomization by using the patient identification number assigned during patient recruitment. (40 people in each group) Standard monitoring is performed when the patient arrives at the operating room. Patients receive oxygen at 5-6 L/min using a simple facial mask, and receive a brachial plexus block under ultrasound guidance. After confirming the success of brachial plexus block, administration of propofol, remimazolam, or dexmedetomidine is started according to the assigned group. Assess the patient's level of consciousness through the MOAA/S (modified observer's assessment of alertness/sedation scale) scale. The drug injection ends when the skin suture is started after the main procedure. The time from the end of injection of each drug until MOAA/S becomes 5 points is measured. After the patient is transferred to the recovery room, the Aldrete score is assessed. The recovery profile, perioperative hemodynamic change, desaturation event, block duration, patient movement during surgery, patient satisfaction, and surgeon's satisfaction were investigated and analyzed for comparison.

NCT05856617
It is known that morbidly obese patients are often accompanied by cardiovascular complications such as hypertension, cardiac hypertrophy, and diastolic dysfunction, and are known to increase the risk of hypotension during anesthesia induction. Remimazolam is widely used in Japan and the United States, and it was approved as a drug for general anesthesia and sedation in Korea in 2021. It was reported that remimazolam caused less hypotension after induction of anesthesia than propofol. However, there is no study on the use of remimazolam in patients undergoing bariatric surgery due to morbid obesity. Therefore, through this study, we plan to check whether remimazolam is safe and effective as an anesthetic-inducing agent for morbidly obese patients undergoing bariatric surgery.
NCT05103696
Studies have shown that etomidate combined with propofol in gastroscopy has high safety and lower incidence of hypoxia and hypotension, suggesting the advantages of etomidate combined with propofol in elderly patients. Remimazolam Besylate is a 1.1 class new drug that acts on GABA receptors and is metabolized by plasma esterase with fast metabolism time, only 1/7 of midazolam, which may be more suitable for elderly patients. Therefore, this study intends to explore the safety and effectiveness of two sedation schemes in gastroenteroscopy for elderly patients.
NCT05891145
Atrial fibrillation (AF) is the most common cardiac severe arrhythmia globally and is associated with an increased risk of mortality and morbidity, with a loss of 6.0 million disability-adjusted life-years worldwide in 2017, conferring 0.24% of total disability-adjusted life-years globally. Due to the absence of knowledge of AF pathogenesis, currently, available therapies do not prevent AF onset or progression in 85% of patients. Despite the identification of novel druggable targets that are involved in the pathogenesis of AF, the translation of these findings to clinical drug studies is limited. Postoperative atrial fibrillation (POAF) is the most common type of secondary AF. The incidence of POAF after coronary artery bypass grafting (CABG) is approximately 30%. About 16% of patients developed POAF in cardiac surgery even with the international guideline recommended perioperative beta-blocker intervention. Remimazolam is a newly approved benzodiazepine sedative indicated for the induction and maintenance of procedural sedation in adults, with significantly reduced sedation and recovery time. It was also found to be with an anti-inflammatory effect and therefore might have an impact on POAF since AF is closely related to the inflammatory response of myocardial tissue and inflammatory factors such as TNF-α. So, the RePAF trial intends to explore whether remimazolam application in induction and maintenance for general anesthesia during cardiac surgery can reduce the incidence of POAF in patients with CABG, and the effect on the postoperative plasma levels of inflammatory factors and stress factors.
NCT05527314
As a novel ultra-short-acting benzodiazepines drugs, Remimazolam has been accepted for induction and maintenance of clinical anesthesia. Compared to the traditional benzodiazepines drugs, Remimazolam combines the safety of midazolam with the effectiveness of propofol, and also has the advantages of acting quickly, short half-life, no injection pain, slight respiratory depression, independent of liver and kidney metabolism, long-term infusion without accumulation, and has a specific antagonist: flumazenil. This study aims to investigate whether Remimazolam reduces the incidence of emergence agitation in children after ophthalmic surgery, compared to sevoflurane (RCT).
NCT05533580
Cerebral autoregulation (CA) is the property of the cerebral vascular bed to maintain cerebral perfusion in the presence of changes in blood pressure. In the case of anesthesia, altered cerebral autoregulation, including altered carbon dioxide and hemodilution, can impair physiological changes in the body and lead to poor postoperative prognosis. As a novel ultra-short-acting benzodiazepines drugs, remimazolam has been accepted for induction and maintenance of clinical anesthesia. Compared to the traditional benzodiazepines drugs, remimazolam combines the safety of midazolam with the effectiveness of propofol, and also has the advantages of acting quickly, short half-life, no injection pain, slight respiratory depression, independent of liver and kidney metabolism, long-term infusion without accumulation, and has a specific antagonist: flumazenil. Our study aimed to investigate the different effects of remimazolam and propofol on dynamic cerebral blood flow autoregulation function during general anesthesia.
