Cardiac Arrest and Mortality Related to Intubation Procedure in Critically Ill Adult Patients: A Multicenter Cohort Study

Objectives: To determine the prevalence of and risk factors for cardiac arrest during intubation in ICU, as well as the association of ICU intubation–related cardiac arrest with 28-day mortality. Design: Retrospective analysis of prospectively collected data. Setting: Sixty-four French ICUs. Patients: Critically ill patients requiring intubation in the ICU. Interventions: None. Measurements and Main Results: During the 1,847 intubation procedures included, 49 cardiac arrests (2.7%) occurred, including 14 without return of spontaneous circulation (28.6%) and 35 with return of spontaneous circulation (71.4%). In multivariate analysis, the main predictors of intubation-related cardiac arrest were arterial hypotension (systolic blood pressure 25 kg/m2; odds ratio = 2.005 [1.017–3.951]; p = 0.0445), and age more than 75 years old (odds ratio = 2.251 [1.080–4.678]; p = 0.0297). Overall 28-day mortality rate was 31.2% (577/1,847) and was significantly higher in patients who experienced intubation-related cardiac arrest than in noncardiac arrest patients (73.5% vs 30.1%; p
