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 Results may not be published yet.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

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.

Summary

This study tested whether the position of a child's head (neutral, sniffing, or beyond sniffing) affects how well a laryngeal mask works during anesthesia. Researchers measured air leaks and ease of insertion in 205 children aged 2-19. The goal is to find the best head position for safer airway management in kids.

What this could mean

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

Active substance
laryngeal mask insertion in different head positions
What this could lead to
If successful, this could help anesthesiologists choose the best head position for children to improve airway management during surgery.
What could go wrong
This is a small, completed trial with no phase, so results may not apply to all children or situations. It only measures air leak, not overall safety or outcomes.

This is an AI summary of the original study and may miss details. Read our disclaimer.
