March 6, 2017 updated by: Nan Jiang

Effects of Dexmedetomidine on Post-operative Blood Pressure in Patients Undergoing Brain Arteriovenous Malformation Embolization

Aim of this trial is to study the effect of Dexmedetomidine on post-operative blood pressure in patients undergoing brain arteriovenous malformation embolization. The patients were randomized allocated to either Dexmedetomidine group or Control group. Patients in Dexmedetomidine group will receive intravenous Dexmedetomidine while the control group will receive normal saline. Post-operative anti-hypertensive drug, Visual analogue score,post-operative analgesics consumption, Quality of Recovery score, Ramsay score, and adverse events were recorded.

Detailed Description

Aim of this trial is to study the effect of Dexmedetomidine on post-operative blood pressure in patients undergoing brain arteriovenous malformation embolization. The patients were randomized allocated to either Dexmedetomidine group or Control group according to a random number. Patients in Dexmedetomidine group will receive intravenous Dexmedetomidine while the control group will receive normal saline. Post-operative anti-hypertensive drug, Visual analogue score,post-operative analgesics consumption, Quality of Recovery score-15 items, Ramsay score, and adverse events were recorded.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
