Using the Peripheral Perfusion Index to predict extubation success

Official title: The Role of Peripheral Perfusion Index as a Predictive Factor During Weaning Process

Run by Gaziosmanpasa Research and Education Hospital · NCT07120672 · Data updated 2026-11-12

This will test whether the Peripheral Perfusion Index (PPI) can help predict if adult ICU patients will be successfully extubated after a spontaneous breathing trial.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) in the ICU who have been on mechanical ventilation for at least 48 hours and are scheduled for extubation after a spontaneous breathing trial are ideal candidates.

Probably not a fit

Patients with peripheral vascular disease, prior hand surgery, persistent hemodynamic instability, or those not planned for extubation are unlikely to benefit from this approach.

What this trial studies

This is a prospective, single-center observational study in the Anesthesia ICU at Gaziosmanpaşa Training and Research Hospital that will enroll adult patients ventilated for at least 48 hours who undergo a spontaneous breathing trial. PPI will be measured and its ability to predict extubation failure will be compared with standard weaning criteria such as RSBI, PaO2/FiO2 ratio, and respiratory rate. Spontaneous breathing trials will be performed using pressure support (5 cmH2O) and PEEP (5 cmH2O), with extubation decisions made by the attending intensivist; patients will be monitored for reintubation for 48 hours. The study excludes patients with peripheral vascular disease, recent hand surgery, ongoing hemodynamic instability, or those who cannot be followed during the study period.

Why it matters

Potential benefit: If successful, PPI could offer a simple, noninvasive bedside measure to better predict extubation outcomes and potentially reduce reintubation and related complications.

How similar studies have gone: Small observational studies have reported correlations between PPI changes and weaning or perfusion status, but PPI is not yet validated in large multicenter trials for predicting extubation outcomes.
