About this study
Official title: Effects of Remote Ischemic Preconditioning in Cutaneous Microcirculation of Different Wounds
In plastic and reconstructive surgery, treatment strategies of second-degree burns, superficial wounds and chronic wounds aim at reducing infection and improving microcirculation. Although previous studies indicate that remote ischemic preconditioning (RIPC) can accelerate wound healing, only a few studies focused on the elucidation of its mechanisms of action. Therefore, the aim of this study is to evaluate the microcirculatory effects of remote ischemic preconditioning on second-degree burns, superficial and chronic wounds in a human in-vivo setting for the first time.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intervention: Remote Ischemic PreconditioningProcedure or surgery
Remote Ischemik Preconditioning is performed using a Blood Pressure Cuff with a pressure slightly above patients' blood pressure on the upper arm.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in microcirculation (composite measure)
- capillary blood flow [arbitrary units AU]

Measured: Baseline and 1 minute post-dose
Secondary outcomes (1)
Change in microcirculation (areolar measure)

Questions about this trial
What is this clinical trial studying?
A study testing Intervention: Remote Ischemic Preconditioning in people with Burn Injury and Acute Wound, run by University Hospital Schleswig-Holstein at 1 site in Germany.
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 4 inclusion and 14 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 24 Feb 2023. 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 Germany. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
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?
Change in microcirculation (composite measure) (time frame: Baseline and 1 minute post-dose). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 24 Feb 2023.
