Feasibility of Corrected Carotid Flow Time for Predicting Short-term Outcomes After Cardiac Surgery in the Intensive Care Unit
Authors' conclusion
In this pilot cohort, early ccFT measured by a wearable and continuous monitoring carotid Doppler was independently associated with longer MV and ICU LOS and showed good discrimination for 24- and 48-hour endpoints.
Study context
- Population
- Adults (≥18 years) admitted to the intensive care unit (ICU) of a tertiary hospital after cardiac surgery
- Participants
- 43 adults
- Outcome
- Association and discrimination of ccFT for ICU LOS and MV duration
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
- ICU length of stay (LOS); multivariable linear regression, independent risk factor
- B −1.127 (95% CI −1.73 to −0.524); P = 0.001
- Mechanical ventilation (MV) duration; multivariable linear regression, independent risk factor
- B −0.438 (95% CI −0.829 to −0.048); P = 0.029
- ICU LOS ≥24 hours
- AUC 0.844 (95% CI 0.726–0.961)
- ICU LOS ≥48 hours
- AUC 0.891 (95% CI 0.795–0.988)
- MV ≥24 hours
- AUC 0.796 (95% CI 0.651–0.942)
- MV ≥48 hours
- AUC 0.859 (95% CI 0.737–0.982)
- Optimal corrected carotid flow time (ccFT) cutoffs for ICU LOS and MV more than 24 hours, respectively
- 314.5 ms and 309 ms
