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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a wearable device that measures lactate levels in sweat for critically ill patients with sepsis or septic shock. High blood lactate is a key sign of tissue oxygen shortage, but current sweat sensors cannot detect the high levels seen in these patients. The new sensor aims to provide a non-invasive way to track lactate continuously, potentially reducing the need for frequent blood tests.

What this could mean

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

Active substance
a wearable sweat sensor that measures lactate levels in sweat
What this could lead to
If successful, this could enable non-invasive, continuous monitoring of lactate in critically ill patients, potentially replacing frequent blood draws.
What could go wrong
This is an early-stage validation study with only 86 participants, so the sensor may not prove accurate or reliable enough for clinical use.

Who can take part

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

Who is studied

Critically ill patients admitted to the surgical intensive care unit (ICU) of the First Affiliated Hospital of Xi'an Jiaotong University with blood lactate concentration greater than 1.5 mmol/L, indicating hyperlactatemia associated with conditions such as sepsis or septic shock. Eligible patients will be assigned to either a sweat collection group or a wearable device monitoring group for concurrent measurement of blood and sweat lactate concentrations.

Ages

16 years and older

Sex

Anyone
