May 5, 2024 updated by: The First Affiliated Hospital with Nanjing Medical University

Safety and Efficacy of Esketamine Combined With Dexmedetomidine for Sedation of Mechanically Ventilated Patients in the ICU: a Prospective, Randomized, Single-center Study

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Dexmedetomidine is a highly selective α2-adrenoceptor agonist with rapid onset of action, easy to wake up, no accumulation in the body, little inhibition of respiration, sedative, hypnotic and anxiolytic effects, and also has a certain analgesic effect.Clinical studies have shown that the use of dexmedetomidine for sedation in ICU patients is beneficial in reducing the duration of mechanical ventilation and the incidence of delirium is low, but the sedative effect of dexmedetomidine is relatively weak, and has the side effects of slowing down heart rate and lowering blood pressure, so its clinical application is limited.Esketamine is an isomer of ketamine, its effect is stronger than ketamine, and glutamate N-methyl D-aspartate (NMDA) receptor binding, play a sedative, hypnotic, analgesic effect, rapid onset, strong effect, and small respiratory inhibition, bronchodilator effect, the disadvantage is that there is a vasoconstrictor effect can cause increased blood pressure, increased heart rate.

The combination of esketamine and dexmedetomidine can provide effective sedation and analgesia with the advantages of maintaining hemodynamic stability, maintaining stable spontaneous breathing and reducing psychiatric symptoms, and has been successfully used in clinical operations such as endoscopy, pediatric anesthesia and outpatient tooth extraction.

The effectiveness and safety of esketamine in combination with dexmedetomidine for the sedation of mechanically ventilated patients in the ICU has not been evaluated. In this study, a prospective, randomized, controlled, single-center study was conducted to evaluate the efficacy and safety of esketamine in combination with dexmedetomidine for the sedation of mechanically ventilated patients in the ICU.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
