Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Sufentanil is a classical drug for postoperative analgesia. Dexmedetomidine is a commonly used α2-adrenergic receptor, and it helps provide sedation, analgesia and inhibition of sympathetic activation. The investigators propose to recruit 120 patients who is undergoing the arteriovenous malformation embolism operation in department of Neurosurgery. Patients will be randomly divided into 4 groups(control group, sufentanil and low dexmedetomidine dose group, sufentanil and middle dexmedetomidine dose group, sufentanil and high dexmedetomidine dose group), then the investigators select post-operative records to determine whether dexmedetomidine can take a positive role in neurosurgical analgesia.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
