What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing whether adding a cold atmospheric plasma device to standard wound care helps different types of wounds heal better. The device uses low-temperature plasma to kill bacteria and promote healing. Researchers will compare 500 patients who get plasma therapy plus standard care with 500 who get standard care alone, tracking healing rates, pain, and scarring for up to 6 months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cold atmospheric plasma device
What this could lead to
If it works, this could provide a new, non-drug way to help wounds heal faster and with less pain.
What could go wrong
This is an observational study, not a controlled trial, so results may be less reliable. The device is still experimental and may not work for all wound types.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will be recruited from patients presenting with acute wounds, chronic wounds, post-grafting wounds, or sutured wounds at the wound care centers, burn units, or plastic surgery departments of 10 participating tertiary hospitals across China. Eligible participants are those who require wound management and meet the inclusion criteria. Patients in the plasma device group will be enrolled prospectively from those receiving standard wound care plus plasma device therapy as part of their routine clinical care. Control group participants will be derived from either: (1) concurrent patients receiving standard wound care alone at the same centers, or (2) retrospectively identified patients from medical records who received standard wound care without plasma therapy. Propensity score matching will be applied to balance baseline characteristics between the two groups. No special restrictions on gender, race, or socioeconomic status will be applied.
