Summary

Postoperative delirium is one of the most common serious complications after major surgery and is associated with undesirable consequences. Prevention of postoperative delirium is recommended in the clinical guidelines and consensus statements. Dexmedetomidine, a highly selective α2-adrenergic receptor agonist, has been investigated as a pharmacological intervention to prevent postoperative delirium. Several randomized controlled trials have shown that prophylactic use of low-dose dexmedetomidine may decrease the incidence of postoperative delirium in patients after cardiac and non-cardiac operations. However, neurosurgical patients are often excluded from previous studies due to potential consciousness and cognition impairment. The investigators design this pilot study aiming to clarify the feasibility and safety of use of low-dose dexmedetomidine for prevention of postoperative delirium in patients after intracranial operation for brain tumor.

Detailed description

Postoperative delirium is one of the most common serious complications after major surgery and is associated with undesirable consequences. Prevention of postoperative delirium is recommended in the clinical guidelines and consensus statements. Dexmedetomidine, a highly selective α2-adrenergic receptor agonist, has been investigated as a pharmacological intervention to prevent postoperative delirium. Several randomized controlled trials have shown that prophylactic use of low-dose dexmedetomidine (0.1 ug/kg/hour without loading infusion) may decrease the incidence of postoperative delirium in patients after cardiac and non-cardiac operations. However, neurosurgical patients are often excluded from previous studies due to potential consciousness and cognition impairment. The investigators design this pilot randomized controlled trial aiming to clarify the feasibility and safety of use of low-dose dexmedetomidine for prevention of postoperative delirium in patients after intracranial operation for brain tumor.

Conditions

• Central Nervous System Diseases

Interventions

Type	Name	Description
DRUG	Dexmedetomidine	Dexmedetomidine hydrochloride (200 μg/2 ml) is diluted with normal saline to 50 ml and is continuously intravenous infused at a rate of 0.025 ml/kg/hour (dexmedetomidine 0.1 μg/kg/hour). The intravenous infusion begins immediately after enrollment until 08:00 AM on the postoperative day one.
DRUG	Normal saline group	Normal saline is also diluted with normal saline to 50 ml and is continuously intravenous infused at a rate of 0.025 ml/kg/hour, which is the same with the dexmedetomidine group. The intravenous infusion begins immediately after enrollment until 08:00 AM on the postoperative day one.
