NCT ID NCT05998564

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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested two non-invasive monitors that track pain in children aged 1-12 during surgery. The monitors measure skin conductance and a pain index to see how well they detect pain events. Researchers compared their readings to find which one is more reliable for guiding pain treatment.

What this could mean

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

What this could lead to
If successful, this could help doctors choose the best pain monitor for children under anesthesia, improving pain management.
What could go wrong
This is a small, completed observational study with only 50 children. Results may not apply to all surgeries or ages, and neither monitor is proven to improve outcomes.

Who is studied

A total of 50 patients. 25 patients aged 1-4 years old, and 25 patients aged 5-12 years old that are scheduled to undergo elective surgery under general anaesthesia. Patients will be enrolled after obtaining written informed consent. We decided to evaluate the SCA and NOL index in two age groups because of the significant differences of maturations of the bodies across different ages that might influence the measurements made by the SCA and NOL monitor. Furthermore the maturation of the brain of a paediatric patient also differs significantly across different ages. Leading to significant differences in EEG patterns and corresponding BIS monitor values across age groups 1-4 and groups 5-11. Therefore, assessing the NOL and SCA in these two difference age groups results in a better ability to assess the homogeneity of the population as we will also be able to quantify and compare the depth of anesthesia through BIS monitor in these two age groups.
