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 < 90 mm Hg) prior to intubation (odds ratio = 3.406 [1.797-6.454]; p = 0.0002), hypoxemia prior to intubation (odds ratio = 3.991 [2.101-7.583]; p < 0.0001), absence of preoxygenation (odds ratio = 3.584 [1.287-9.985]; p = 0.0146), overweight/obesity (body mass index > 25 kg/m; 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 < 0.001). After multivariate analysis, intubation-related cardiac arrest was an independent risk factor for 28-day mortality (hazard ratio = 3.9 [2.4-6.3]; p < 0.0001).

CONCLUSIONS: ICU intubation-related cardiac arrest occurs in one of 40 procedures with high immediate and 28-day mortality. We identified five independent risk factors for cardiac arrest, three of which are modifiable, possibly to decrease intubation-related cardiac arrest prevalence and 28-day ICU mortality.
