| Fecha: | 2022 |
| Resumen: | OBJECTIVES: To characterize clusters of double triggering and ineffective inspiratory efforts throughout mechanical ventilation and investigate their associations with mortality and duration of ICU stay and mechanical ventilation. DESIGN: Registry-based, real-world study. Background: Asynchronies during invasive mechanical ventilation can occur as isolated events or in clusters and might be related to clinical outcomes. Subjects: Adults requiring mechanical ventilation greater than 24 hours for whom greater than or equal to 70% of ventilator waveforms were available. INTERVENTIONS: We identified clusters of double triggering and ineffective inspiratory efforts and determined their power and duration. We used Fine-Gray's competing risk model to analyze their effects on mortality and generalized linear models to analyze their effects on duration of mechanical ventilation and ICU stay. MEASUREMENTS AND MAIN RESULTS: We analyzed 58,625,796 breaths from 180 patients. All patients had clusters (mean/d, 8. 2 [5. 4-10. 6]; mean power, 54. 5 [29. 6-111. 4]; mean duration, 20. 3 min [12. 2-34. 9 min]). Clusters were less frequent during the first 48 hours (5. 5 [2. 5-10] vs 7. 6 [4. 4-9. 9] in the remaining period [p = 0. 027]). Total number of clusters/d was positively associated with the probability of being discharged alive considering the total period of mechanical ventilation (p = 0. 001). Power and duration were similar in the two periods. Power was associated with the probability of being discharged dead (p = 0. 03), longer mechanical ventilation (p < 0. 001), and longer ICU stay (p = 0. 035); cluster duration was associated with longer ICU stay (p = 0. 027). CONCLUSIONS: Clusters of double triggering and ineffective inspiratory efforts are common. Although higher numbers of clusters might indicate better chances of survival, clusters with greater power and duration indicate a risk of worse clinical outcomes. |
