Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Mechanical ventilation, painful stimulation, and sleep disturbances are important risk factors of delirium in ICU patients. Delirium is an acutely occurred brain dysfunction symdrome characteristized with fluctuating disturbances in attention, cognition, and consciousness, and is reported to occur in up to 80% of ICU patients with mechanical ventilation. Delirium occurrence is associated with worse outcomes, including prolonged mechanical ventilation duration, extended ICU and hospital stays, increased healthcare burden and costs, and elevated mortality risk, as well as long-term sequelae including cognitive decline, reduced quality of life, and decreased survival.
Dexmedetomidine is a highly selective α2-adrenergic receptor agonist with sedative, analgesic, and anxiolytic effects. It exerts effects by activating the endogenous sleep-promoting pathways, inducing a state like non-rapid eye movement sleep. Ketamine is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist. Esketamine, the more potent enantiomer of ketamine, has a higher affinity for the NMDA receptor and is approximately twice as potent as ketamine, with a lower incidence of adverse effects. Both dexmedetomidine and ketamine are recommended for sedation and analgesia in ICU patients. However, sedative dose dexmedetomidine is associated with bradycardia and hypotension. Even low-dose esketamine can induce psychotropic side effects such as dissociation, hallucinations, and nightmares.
The sedative effects of dexmedetomidine can help mitigate the psychiatric side effects of esketamine. Recent studies showed that dexmedetomidine-esketamine combination improved analgesia and sleep quality without increasing psychiatric side effects. It is hypothesized that dexmedetomidine-esketamine combination for sedation and analgesia in ICU patients with mechanical ventilation may reduce delirium and improve respiratory recovery.

Dexmedetomidine-Esketamine Combination
Sedation-analgesia is provided with dexmedetomidine-esketamine combination for up to 14 days or until discharge from the ICU. The formulation consists of dexmedetomidine 200 μg/2 ml and esketamine 100 mg/4 ml, diluted with normal saline to a total volume of 50 ml, resulting in a dexmedetomidine concentration of 4 μg/ml and an esketamine concentration of 2 mg/ml.
Dexmedetomidine-Esketamine Combination
For patients with invasive ventilation, nighttime sedation (20:00-06:00) is provided with an initial infusion rate of \[0.05×kg\] ml/h which is increased by \[0.025×kg\] ml/h every 10 min, until the Richmond Agitation-Sedation Scale (RASS) reaches -2 to -1, maximal infusion rate reaches \[0.175×kg\] ml/h, or adverse reactions occur. Daytime sedation (06:00-20:00) is provided as above when considered necessary by the ICU physicians, with a target RASS score of -2 to +1.
For patients with non-invasive ventilation (including high-flow nasal oxygenation) or without assisted ventilation, nighttime sedation (20:00-06:00) is provided with an initial infusion rate of \[0.0125×kg\] ml/h which is increased by \[0.0125×kg\] ml/h every 10 min, until the RASS reaches -1, maximal infusion rate reaches \[0.05×kg\] ml/h, or adverse reactions occur. Daytime sedation (06:00-20:00) is typically not required but is provided when considered necessary by the ICU physicians, with a target RASS score of -1 to +1.
