Conditions

Consciousness Disorders, Esketamine

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.

Interventions

DRUGEsketamine

Esketamine ( 50mg, dissolved in 50ml normal saline ) 0.3mg / kg will be infused intravenously at a constant speed within 30 min after tracheal intubation/pneumatectomy fixation.

DRUGnormal saline

Same amount of normal saline will be infused intravenously at a constant speed within 30 min after tracheal intubation/pneumatectomy fixation.
