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 Results may not be published yet.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.

Summary

This study checks whether three common ways of measuring body temperature during surgery give matching results. It compares a nasopharyngeal probe (the standard), an ear thermometer, and a forehead sensor in adults having elective surgery under general anesthesia. The goal is to see if the simpler devices can be used safely instead of the probe, helping prevent complications from low body temperature during operations.

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 the devices agree closely, doctors could safely use simpler, less invasive temperature monitors during surgery, reducing discomfort and risk.
What could go wrong
This is an observational study, not a treatment trial. It may find that the devices do not agree well, and results may not apply to all patients or surgeries.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years * We will include 3 independent groups of patients receiving general anesthesia with tracheal intubation: Group 1: Cardiac surgery Group 2: Thoracic surgery Group 3: General surgery, including neurosurgery * Expected surgical duration ≥ 60 minutes * ASA Physical Status Classification I- III * Able to provide written informed consent Exclusion Criteria: * Prior nasal surgery, nasal polyps, deviated nasal septum, or significant epistaxis history precluding safe nasopharyngeal probe insertion * Otitis media, tympanic membrane perforation, significant cerumen impaction, or external auditory canal deformity that would prevent reliable infrared tympanic temperature measurement * Facial or forehead skin lesions, burns, or known adhesive hypersensitivity at the planned 3M SpotOn™ application site, craniotomy, and head and neck surgery. * Baseline core temperature \< 35.0°C or \> 38.5°C at preoperative assessment * Planned use of neuraxial anesthesia as the primary or adjunct technique * Emergency procedures, pregnancy, or procedures involving deliberate hypothermia or cardiopulmonary bypass.
