Early Deep-to-light vs. Continuous Light Sedation for ICU Patients with Mechanical Ventilation

sciencedirect.com October 15, 2024

Compared to the continuous light sedation, early deep-to-light sedation strategy was associated with improved patient outcomes, and continuous deep sedation was confirmed with poorer patient outcomes.

In total, 6700 patients (2627 ICU-HAI, 4073 MIMIC) were included in the cohort study, of whom 2689 received CLS, 2079 CDS and 1932 DTLS.

Compared to CLS, DTLS was associated with lower ICU mortality (9.3% vs. 11.0%; pooled adjusted HR 0.78, 95% CI 0.66-0.94) and hospital mortality (16.0% vs. 14.1%; 0.86, CI 0.74-1.00); and CDS was associated with higher ventilator mortality (32.8% vs. 7.0%; 4.65, 3.91-5.53), ICU mortality (40.6% vs. 11.0%; 3.39, 2.95-3.90) and hospital mortality (46.8% vs. 14.1%; 3.27, 2.89-3.71) than CLS. All HRs were qualitatively consistent in both cohorts.
