About this study

Official title: Impact of Intraoperative Goal-directed Blood Pressure Management and Dexmedetomidine on Outcomes of High-risk Patients After Major Abdominal Surgeries: a 2×2 Factorial Randomized Controlled Trial

Perioperative organ injuriy remain an important threat to patients undergoing major surgeries. Intraoperative hypotension is associated with an increase in postoperative morbidity and mortality. Whereas individualized intraoperative blood pressure management is likely to decrease the incidence of postoperative organ injury when compared with standard blood pressure management strategy. Dexmedetomidine, a highly selective alpha2 adrenergic agonist, has been shown to provide organ protective effects. This study aims to investigate the impact of intraoperative goal-directed blood pressure management and dexmedetomidine infusion on incidence of postoperative organ injury in high-risk patients undergoing major surgery.

Read the detailed description

The number of patients undergoing surgeries is increasing worldwide. However, some patients develop complications or even die after surgery. Perioperative organ injury is the leading cause of the unfavorable outcomes.

Hypotension is not uncommon during major surgery and is highly responsible for the inadequate perfusion and organ injury. A recent study showed that individualized blood pressure management decreases the incidence of postoperative organ injury when compared with standard blood pressure management strategy.

Dexmedetomidine is a highly selective alpha2 adrenergic agonist. Previous studies showed that dexmedetomidine provides organ protection in various conditions. In a recent meta-analysis, perioperative dexmedetomidine reduceds the occurrence of postoperative delirium. However, whether it can reduce postoperative complications remains inconclusive.

This study aims to investigate the impact of intraoperative goal-directed blood pressure management and dexmedetomidine infusion on the incidence of postoperative organ injury in high-risk patients undergoing major abdominal surgery.

A Phase 4 study testing Dexmedetomidine, Goal-directed blood pressure management and Routine blood pressure management in people with Blood Pressure and Dexmedetomidine, run by Peking University First Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of organ injury and other complications within 30 days after surgery. (time frame: Up to 30 days after surgery.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03933306, which also lists 32 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jul 2025.
