Impact Dexmedetomidine on Postoperative Delirium in Patients After Intracranial Operation for Brain Tumor

10. januar 2021 opdateret af: Jian-Xin Zhou, Capital Medical University

Impact of Prophylactic Use of Dexmedetomidine on Postoperative Delirium in Patients After Intracranial Operation for Brain Tumor: a Pilot Randomized Controlled Trial

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.

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Placebo komparator: Normal saltvandsgruppe
Kontinuerlig intravenøs infusion af normalt saltvand med en hastighed på 0,025 ml/kg/time startede umiddelbart efter indskrivning indtil kl. 08:00 på den postoperative dag ét.
Medicin: 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.
Andre navne:
  • 0,9% natriumchlorid
Eksperimentel: Dexmedetomidine group
Continuously intravenous infusion of dexmedetomidine hydrochloride at a rate of 0.1 μg/ kg/hour (0.025 ml/kg/hour) started immediately after enrollment until 08:00 AM on the postoperative day one.
Medicin: Dexmedetomidin
Dexmedetomidinhydrochlorid (200 μg/2 ml) fortyndes med normalt saltvand til 50 ml og infunderes kontinuerligt intravenøst ​​med en hastighed på 0,025 ml/kg/time (dexmedetomidin 0,1 μg/kg/time). Den intravenøse infusion begynder umiddelbart efter indskrivning indtil kl. 08.00 på den postoperative dag ét.
Andre navne:
  • Dexmedetomidin hydrochlorid

Foranstaltningsbeskrivelse
Tidsramme
Incidence of study agent interruption during the study
Tidsramme: From the start of study agent infusion to postoperative day 1
Predicted adverse events in the present study included bradycardia (defined as heart rate lower than 50 beats/min), hypotension (defined as systolic blood pressure lower than 90 mmHg), tachycardia (defined as heart rate greater than 100 beats/min), hypertension (defined as systolic blood pressure greater than 160 mmHg) and hypoxemia (defined as pulse oxygen saturation lower than 90%). The treatment of adverse events was determined by the responsible attending ICU physicians, who could stop the study agent infusion when the treatment failure or other conditions deemed necessary.
From the start of study agent infusion to postoperative day 1
