See if reintubation risk can be predicted after major surgery
Official title: Assessment of Reintubation Risk Using Multiple Parameters in Postoperative Intensive Care Unit Patients
Run by Prof. Dr. Cemil Tascıoglu Education and Research Hospital Organization · NCT07672106 · Data updated 2026-11-12
This observational study tests whether ultrasound measurements of the diaphragm and chest muscles, plus the ROX index, can help predict which adults in the ICU after major surgery might need reintubation.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years and older who are extubated in the operating room and admitted to the ICU with spontaneous breathing after major surgery.
✕Probably not a fit
Patients who remain stable without risk indicators or who do not require reintubation may see limited direct benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
In this prospective observational study, adult postoperative ICU patients who were extubated in the OR and are breathing spontaneously will undergo bedside ultrasound assessments of diaphragm thickness, parasternal intercostal muscle thickness, and lung ultrasound score within the first hours after ICU admission. The ROX index will be calculated from oxygen saturation, inspired oxygen, and respiratory rate, and perioperative fluid balance will be recorded. Patients will be followed for 48 to 72 hours to see if reintubation is required. This study aims to identify early markers that could indicate reintubation risk in a real-world ICU setting without intervening treatments.
Why it matters
Potential benefit: If successful, the findings could help clinicians identify patients at higher risk of reintubation and tailor monitoring and care accordingly.
How similar studies have gone: Previous work in similar areas has shown promise for using ultrasound and clinical indices to predict reintubation, but this exact combination in this context is relatively novel.

Inclusion Criteria: Adult patients aged 18 years and older Patients requiring postoperative intensive care follow-up after major surgery, including abdominal, vascular, orthopedic, or ear, nose, throat, head and neck surgery Patients extubated in the operating room and admitted to the intensive care unit with spontaneous breathing Patients without any clinical condition preventing the planned measurements within the first 0-2 hours after ICU admission (T0 and T1) Patients for whom written informed consent can be obtained from the patient or legally authorized representative Patients admitted to the intensive care unit within the specified study period after ethics committee approval and enrolled consecutively Exclusion Criteria: Patients younger than 18 years of age Patients who leave the operating room intubated or are admitted to the intensive care unit while intubated Patients with a tracheostomy Patients with a history of diaphragmatic paralysis Patients with a significant neuromuscular disease, such as ALS, myasthenia gravis, or similar conditions Patients with conditions that significantly prevent ultrasound measurements, including marked subcutaneous emphysema, large dressings or bandages covering the measurement area, inability to access the measurement site due to drains or the surgical field, or inability to obtain technically adequate images Patients in whom the planned measurements cannot be performed due to clinical instability requiring emergency intubation immediately after ICU admission Patients from whom informed consent cannot be obtained, or patients or legally authorized representatives who refuse participation
