RESUMO

BACKGROUND: Few data are available on patients who have experienced anaphylaxis and were admitted to ICUs. The purpose of this observational study was to describe the epidemiology and management of these patients. METHODS: This was a multicentre retrospective study carried out in 23 French ICUs between 2012 and 2017. All patients who suffered anaphylaxis and were transferred to an ICU were included. Data were collected using an electronic database after approval by an ethics committee. RESULTS: A total of 339 patients were included, and 17 (5%) died secondary to anaphylaxis. The main triggers were drugs (77%), contrast media (11%), and food (7%). Epinephrine was administered before ICU admission in 88% of patients with Grade III anaphylaxis and 100% of patients with Grade IV anaphylaxis. Most patients with Grades III and IV anaphylaxes did not receive the recommended dose of i.v. fluid of 30 ml kg-1 within the first 4 h of ICU admission. The time to epinephrine administration was not statistically different between survivors and non-survivors, but non-survivors received a higher dose of epinephrine (median: 5 [3-10] vs 3 [2-7] mg; P<0.0001), which suggests that some forms of anaphylactic shock may be resistant to epinephrine. In multivariate analysis, only lactate concentration at ICU admission was a predictor of death (odds ratio: 1.47 [1.15-1.88]; P=0.002). CONCLUSIONS: Lactate concentration at ICU admission appeared to be the most reliable criterion for assessing prognosis. Epinephrine is widely used during anaphylaxis, but the volume of fluid resuscitation was consistently lower than recommended. CLINICAL TRIAL REGISTRATION: NCT04290507.

RESUMO

PURPOSE: Noninvasive ventilation (NIV) had proven benefits in clinical trials that included selected patients admitted to highly skilled centers. Whether these benefits apply to every patient and in everyday practice deserves appraisal. The aim of the study was to assess the use and outcomes of NIV over the last 15 years. METHODS: Multicenter database study of critically ill patients who required ventilatory support for acute respiratory failure between 1997 and 2011. The impact of first-line NIV on 60-day mortality was evaluated using a marginal structural model. Follow-up was censored on day 60. RESULTS: Of 3,163 patients, 1,232 (39 %) received NIV. Over the study period, first-line NIV increased from 29 to 42 %, and NIV success rates increased from 69 to 84 %. NIV decreased 60-day mortality [adjusted hazard ratio (aHR), 0.75; 95 % confidence interval (95 % CI), 0.68-0.83; P < 0.0001]. This protective effect was observed in patients with acute-on-chronic respiratory failure (aHR, 0.71; 95 % CI, 0.57-0.90; P = 0.004), but not in patients with cardiogenic pulmonary edema (aHR, 0.85; 95 % CI, 0.70-1.03; P = 0.10) or in patients with hypoxemic ARF, either immunocompetent (aHR, 1.18; 95 % CI, 0.87-1.59; P = 0.30) or immunocompromised (aHR, 0.89; 95 % CI, 0.70-1.13; P = 0.35). NIV failure was an independent time-dependent risk factor for mortality (aHR, 4.2; 95 % CI, 2.8-6.2; P < 0.0001). CONCLUSIONS: The use of NIV increased steadily over the study period. First-line NIV was associated with better 60-day survival and fewer ICU-acquired infections compared to first-line intubation. Survival benefits from NIV occurred only in patients with acute-on-chronic respiratory failure and immunocompromised patients.
