Conditions
Esketamine
Consciousness Disorders
Interventions
Drug: normal saline
Registration Number
NCT06389344
Lead Sponsor
Beijing Tiantan Hospital
Brief Summary

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 Hospital. 0.3mg/kg esketamine or saline will be infused will be infused intravenously at a constant speed within 30 min after tracheal intubation/pneumatectomy fixation. Coma recovery scale-revised, Glasgow coma scale, Full Outline of UnResponsiveness scores, SedLine multi-channel electroencephalogram and perioperative adverse events after surgery will be investigated.

Primary Outcome Measures
NameTimeMethod
Coma recovery scale-revised(CRS-R)3±1 day after surgery

The CRS-R ranges from 0 to 23, with a higher score indicating a better state of consciousness.

Secondary Outcome Measures
NameTimeMethod
Coma recovery scale-revised(CRS-R)1,3,6 months after surgery

The CRS-R ranges from 0 to 23,with a higher score indicating a better state of consciousness.

Glasgow coma scale(GCS)3±1 day, 1,3,6 months after surgery

The GCS ranges from 3 to 15,with a higher score indicating a better state of consciousness.

Original EEGduring surgery and 3±1 day after surgery
