Can a Pain Monitor Predict When Postoperative Intensive Care Unit Patients Are Ready to Breathe on Their Own? A Pilot Study

NCT07771101

RecruitingN/A

Sponsor: Seoul National University Hospital

Conditions: Ventilator Weaning, Airway Extubation, Respiration, Artificial

Countries: South Korea

The goal of this observational study is to learn if a chest monitor that tracks heart rhythm can help predict whether adults on a breathing machine after surgery will be able to breathe on their own once the breathing tube is removed. It is being done in adults recovering from surgery in the intensive care unit (ICU). The main questions it aims to answer are: Can heart rhythm patterns, measured soon after ICU admission and during a breathing test, show whether a patient is likely to breathe well without the machine? Do these patterns change in a helpful way when the breathing tube is removed? Participants will: Have soft, sticky patches placed on their chest, similar to those used for a regular heart monitor Have their heart rhythm recorded for 5 minutes at four times: soon after ICU admission, before a breathing test, during the breathing test, and right after the breathing tube is removed Continue to receive their usual ICU care; doctors will not see the monitor's readings, so these readings will not affect any treatment decisions

Sex: ALL

Age: 18 Years to —

Healthy volunteers: No

Study type: OBSERVATIONAL

Eligibility criteria

Inclusion Criteria:

* Age 18 years or older
* Admitted to the surgical intensive care unit (ICU) after surgery
* Currently on a breathing machine (mechanical ventilation) through a tube in the airway
* Receiving dexmedetomidine as the main sedative medication, with a stable, predefined level of sedation
* Participant or their legal representative agrees to take part in the study

Exclusion Criteria:

* Permanent irregular heart rhythm (atrial fibrillation or atrial flutter)
* Complete heart block or a heart rhythm that is fully controlled by a pacemaker
* Already has a tracheostomy (a breathing tube placed through the neck)
* A decision has already been made at ICU admission to withhold or withdraw life-sustaining treatment
* Deeply sedated without receiving any sedative medication, suggesting the low alertness may be due to a brain-related problem rather than medication
