RESUMEN
BACKGROUND: Cardiopulmonary complications are common after endoscopy for upper GI (UGI) hemorrhage in the intensive care unit (ICU). OBJECTIVE: To evaluate the practice and outcome of elective prophylactic endotracheal intubation before endoscopy for UGI hemorrhage in the ICU. DESIGN: Retrospective, propensity-matched case-control study. SETTING: A 24-bed medical ICU in a tertiary center. PATIENTS: ICU patients who underwent endoscopy for UGI hemorrhage. MAIN OUTCOME MEASUREMENTS: Cardiopulmonary complications, ICU and hospital length of stay, and mortality. In a propensity analysis, patients who were intubated for airway protection before UGI endoscopy were matched by probability of intubation to controls who were not intubated before UGI endoscopy. RESULTS: Of 307 patients, 53 underwent elective prophylactic intubation before UGI endoscopy. The probability of intubation depended on the Acute Physiology and Chronic Health Evaluation III (APACHE III) score (OR 1.4; 95% CI, 1.2-1.6), age (OR 0.97; 95% CI, 0.95-0.09), the presence of hemetemesis (OR 1.9; 95% CI, 0.8-5.1), previous lung disease (OR 2.1; 95% CI, 0.8-4.9), and the number of transfusions (OR 1.1; 95% CI, 1.0-1.1 per unit). Nonintubated matched controls were identified for all but 4 patients with active massive hemetemesis, who were excluded from matched analysis. Cumulative incidence of cardiopulmonary complications (53% vs 45%, P = .414), ICU length of stay (median 2.2 vs 1.8 days, P = .138), hospital length of stay (6.9 vs 5.9 days, P = .785), and hospital mortality (14% vs 20%, P = .366) were similar. CONCLUSIONS: Cardiopulmonary complications are frequent after endoscopy for acute UGI bleeding in ICU patients and are largely unaffected by the practice of prophylactic intubation.

OBJECTIVE: The optimal role of vasopressor therapy in septic shock is not known. We hypothesized that the variability in the use of vasopressors to treat hypotension is associated with subsequent organ failures. DESIGN: Retrospective observational single-center cohort study. SETTING: Tertiary care hospital. PATIENTS AND PARTICIPANTS: Consecutive patients with septic shock. MEASUREMENT AND RESULTS: Ninety-five patients were enrolled. Serial blood pressure recordings and vasopressor use were collected during the first 12h of septic shock. Median duration of hypotension that was not treated with vasopressors was 1.37h (interquartile range [IQR] 0.62-2.66). Based on the observed variability, we evaluated liberal (duration of untreated hypotension < median) vs. conservative (duration of untreated hypotensionn > median) vasopressor therapy. Compared with patients who received conservative vasopressor therapy, patients treated liberally had similar baseline organ impairment [median Sequential Organ Failure Assessment (SOFA) score 8 vs. 8, p = 0.438] were more likely to be younger (median age 70 vs. 77 years, p = 0.049), to require ventilator support (78 vs. 49%, p < 0.001), and to have progression of organ failures after 24h (59 vs. 37%, p = 0.032). When adjusted for age and mechanical ventilation, early therapy aimed at achieving global tissue perfusion [odds ratio (OR) 0.33, 95% confidence interval (CI) 0.11-0.88), and early adequate antibiotic therapy (OR 0.27, 95% CI 0.09-0.76), but not liberal vasopressor use (OR 2.13, 95% CI 0.80-5.84), prevented progression of organ failures. CONCLUSIONS: In our retrospective study, early adequate antibiotics and achieving adequate global perfusion, but not liberal vasopressor therapy, were associated with improved organ failures after septic shock. Clinical trials which compare conservative vs. liberal vasopressor therapy are warranted.
