Perioperative Dexmedetomidine on Postoperative Delirium in Patients With Brain Tumors

Study Purpose

Neurosurgery is a risk factor for delirium. Dexmedetomidine might reduce delirium by reducing neuroinflammation, improving postoperative analgesia and sleep quality. The the primary hypothesis is that perioperative administration of dexmedetomidine can reduce the incidence of postoperative delirium

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06164314
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A

Additional Details

The investigators will be required to attend the professional training before recruitment and strictly adhere to the study protocol. All the raw data will be recorded in the case report forms. Data will be entered doubly performed by two investigators and monitored securely in an electronic database with password protection at the medical center. The data base will be locked after all data have been cleaned. All the original fles will be maintained in storage for 5 years after completion of the study.

Arms & Interventions

Arms

Experimental: Dex group

Subjects assigned to Dex group will receive a continuous dexmedetomidine infusion (0.4 ug/kg/h) after anesthesia induction until dural closure, and then received an intravenous analgesia pump with dexmedetomidine(0.08ug/kg/h), sufentanil and antiemetic until 48 hours postoperatively

Placebo Comparator: Placebo group

Subjects in the Placebo group were given comparable volumes of normal saline during the surgery, and intravenous analgesia pump also contains sufentanil and antiemetic, but no dexmedetomidine used until 48 hours postoperatively.

Interventions

Drug: - Dexmedetomidine

In Dex group, dexmedetomidine will continue to be used during and after surgery, with a infusion of 0.4ug/kg/ h from anesthesia induction to dural closure, and then 0.08ug/kg/ h to 48 hours postoperatively.In placebo group, equivalent normal saline will be injected during operation, and the intravenous analgesia pump will not contain dexmedetomidine after operation
