Effect of Esketamine on Conscious State in Patients With pDoC
The goal of this clinical trial is to learn about the effect of intraoperative infusion of subanesthetic dose of esketamine on conscious status in patients with prolonged disorders of consciousness under sevoflurane anesthesia. Participants will be patients with prolonged disorders of consciousness undergoing surgery with general anesthesia at Beijing Tiantan …
Sedation With Dexmedetomidine-esketamine Combination and Delirium in ICU Patients
Patients in the intensive care unit (ICU) often develop anxiety and agitation, sleep disturbances, and delirium. Delirium occurrence is associated with worse early and long-term outcomes. Dexmedetomidine and ketamine are recommended for sedation and analgesia in postoperative ICU patients, but each may induce side effects. The sedative effects of dexmedetomidine …
Different Dose Esketamine and Dexmedetomidine for Supplemental Analgesia and Longterm Outcomes
Chronic postsurgical pain (CPSP) refers to pain that occurs or increases after surgery and lasts longer than 3 months. Severe acute postoperative pain is one of the major risk factors of CPSP. Spinal correction surgery is associated with severe pain due to large trauma and long duration. Ketamine and esketamine …
Different Dose Esketamine and Dexmedetomidine Combination for Supplemental Analgesia After Scoliosis Correction Surgery
Scoliosis correction surgery is associated with severe pain. Patients after scoliosis correction surgery usually require high dose opioids and long duration analgesia, which may increase side effects and drug tolerance. In a recent trial, mini-dose esketamine and dexmedetomidine combination as a supplement to sufentanil significantly improved analgesia and subjective sleep …
Subanesthetic Esketamine in Modified ECT for Severe Depression in Adolescents: Clinical and Mechanistic Study
The study design was a randomized, double blind, parallel controlled trial.The goal of this clinical trial is to learn if esketamine-assisted modified electroconvulsive therapy (ESK-MECT) works to treat severe depression in adolescents. It will also learn about the safety of ESK-MECT. The sample size was calculated based on the response …
Anesthesia Techniques, Neuroprotection and Surgical Field in FESS Under Controlled Hypotension
This prospective, randomized controlled trial investigates the effect of four different anesthetic maintenance techniques on surgical field conditions, hemodynamic stability, and neuroprotection during functional endoscopic sinus surgery (FESS) performed under controlled hypotension. Patients are randomly assigned to receive either total intravenous anesthesia with propofol-remifentanil, propofol-remifentanil with adjunct ketamine and magnesium, …
Immunoinflammatory Regulation of Esketamine in Septic Patients
Studies have shown that excessive systemic inflammatory response and concomitant immunosuppression are the main cause of early death in patients with sepsis. Therefore, it is very important to reduce excessive inflammation and improve immunosuppression in the acute phase of sepsis. Clinical studies have shown that esketamine combined with propofol for …
Safety and Efficacy of Esketamine Combined With Dexmedetomidine for Sedation of Mechanically Ventilated Patients
A prospective, randomized controlled study was conducted to compare the effects of esketamine combined with dexmedetomidine in the sedation and analgesia treatment of mechanically ventilated patients in the ICU on the time to awaken, time to extubation, time to mechanical ventilation, time in the ICU, and on delirium.
Mini-dose Dexmedetomidine-Esketamine Supplemented Analgesia in Patients at High-risk of OSA
Patients with obstructive sleep apnea (OSA) are at increased risk of developing sleep disturbances after surgery. Dexmedetomidine is a highly selective α2-adrenergic agonist with sedative, analgesic, and anxiolytic effects. Ketamine is a noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist. Esketamine is the S-enantiomer of racemic ketamine and twice as potent as racemic …
Esketamine on Postoperative Sleep Disturbance of Patients Undergoing Spinal Surgery
The goal of this clinical trial is to learn about the effect of intraoperative esketamine infusion on postoperative sleep disturbance(PSD) of patients undergoing spinal surgery. The main aims to answer are: To explore the effect of intraoperative infusion of esketamine on the incidence of postoperative sleep disturbance and sleep quality …
