RESUMO
BACKGROUND: Haloperidol is frequently used to treat delirium in patients in the intensive care unit (ICU), but evidence of its effect is limited. METHODS: In this multicenter, blinded, placebo-controlled trial, we randomly assigned adult patients with delirium who had been admitted to the ICU for an acute condition to receive intravenous haloperidol (2.5 mg 3 times daily plus 2.5 mg as needed up to a total maximum daily dose of 20 mg) or placebo. Haloperidol or placebo was administered in the ICU for as long as delirium continued and as needed for recurrences. The primary outcome was the number of days alive and out of the hospital at 90 days after randomization. RESULTS: A total of 1000 patients underwent randomization; 510 were assigned to the haloperidol group and 490 to the placebo group. Among these patients, 987 (98.7%) were included in the final analyses (501 in the haloperidol group and 486 in the placebo group). Primary outcome data were available for 963 patients (97.6%). At 90 days, the mean number of days alive and out of the hospital was 35.8 (95% confidence interval [CI], 32.9 to 38.6) in the haloperidol group and 32.9 (95% CI, 29.9 to 35.8) in the placebo group, with an adjusted mean difference of 2.9 days (95% CI, -1.2 to 7.0) (P = 0.22). Mortality at 90 days was 36.3% in the haloperidol group and 43.3% in the placebo group (adjusted absolute difference, -6.9 percentage points [95% CI, -13.0 to -0.6]). Serious adverse reactions occurred in 11 patients in the haloperidol group and in 9 patients in the placebo group. CONCLUSIONS: Among patients in the ICU with delirium, treatment with haloperidol did not lead to a significantly greater number of days alive and out of the hospital at 90 days than placebo.

BACKGROUND: Intravenous fluids are recommended for the treatment of patients who are in septic shock, but higher fluid volumes have been associated with harm in patients who are in the intensive care unit (ICU). METHODS: In this international, randomized trial, we assigned patients with septic shock in the ICU who had received at least 1 liter of intravenous fluid to receive restricted intravenous fluid or standard intravenous fluid therapy; patients were included if the onset of shock had been within 12 hours before screening. The primary outcome was death from any cause within 90 days after randomization. RESULTS: We enrolled 1554 patients; 770 were assigned to the restrictive-fluid group and 784 to the standard-fluid group. Primary outcome data were available for 1545 patients (99.4%). In the ICU, the restrictive-fluid group received a median of 1798 ml of intravenous fluid (interquartile range, 500 to 4366); the standard-fluid group received a median of 3811 ml (interquartile range, 1861 to 6762). At 90 days, death had occurred in 323 of 764 patients (42.3%) in the restrictive-fluid group, as compared with 329 of 781 patients (42.1%) in the standard-fluid group (adjusted absolute difference, 0.1 percentage points; 95% confidence interval [CI], -4.7 to 4.9; P = 0.96). In the ICU, serious adverse events occurred at least once in 221 of 751 patients (29.4%) in the restrictive-fluid group and in 238 of 772 patients (30.8%) in the standard-fluid group (adjusted absolute difference, -1.7 percentage points; 99% CI, -7.7 to 4.3). At 90 days after randomization, the numbers of days alive without life support and days alive and out of the hospital were similar in the two groups. CONCLUSIONS: Among adult patients with septic shock in the ICU, intravenous fluid restriction did not result in fewer deaths at 90 days than standard intravenous fluid therapy.

OBJECTIVE: Recent reviews strongly discourage the routine use of gastric lavage in oral poisonings, but the authors suspected that gastric lavage might still be in widespread use in Denmark. We wished to estimate the extent to which gastric lavage in cases of medical drug poisoning, reported in inquiries to the Danish Poison Information Centre (DPIC) from 2007 to 2010, was performed according to international recommendations and whether adherence to recommendations improved over the period. METHODS AND MATERIALS: Inquiries from hospital and emergency departments (EDs) concerning medical drug poisonings were identified in the DPIC database. Patients receiving gastric lavage prior to inquiry were identified, and demographic and poisoning characteristics were retrieved. Indication for gastric lavage was determined from a predefined set of criteria. RESULTS: 10 740 inquiries from hospitals and EDs were identified, of which 1091 cases received gastric lavage. In logistic regression, the frequency of lavage fell significantly from 13.5% in 2007 to 7.9% in 2010 (odds ratio (OR) 0.547, confidence interval (CI) 0.455-0.659). All criteria for gastric lavage were fulfilled in 60 lavaged cases (5.5%), and the fraction did not improve significantly over the period (OR 1.717, CI 0.791-3.724). No individual criterion for lavage showed consistent improvement over the period. CONCLUSION: Gastric lavage is still widely used in Denmark, mostly on questionable grounds where the procedure is unlikely to be beneficial. Recommendations for gastrointestinal decontamination may need to be promoted more actively, and clinicians should be encouraged to seek toxicological advice before performing gastric lavage.

BACKGROUND: The Losartan Intervention For Endpoint reduction in hypertension (LIFE) study has previously demonstrated a beneficial effect of losartan compared to atenolol-based antihypertensive treatment in patients with essential hypertension and left-ventricular hypertrophy (LVH). However, patient age often influences the choice of antihypertensive drugs. Therefore, we investigated the influence of age on the effects of losartan versus atenolol-based antihypertensive treatment. METHODS: A total of 9193 hypertensive patients with LVH aged 45-83 years were followed for a mean of 4.8 years. Blood pressure, high-density lipoprotein cholesterol (HDL-C), Sokolow-Lyon voltage, Cornell voltage-duration product and urine albumin-creatinine ratio (UACR) were measured yearly throughout the study. Patients were divided into two age groups according to the median age of 67 years and the effects of losartan versus atenolol-based antihypertensive treatment on the primary composite endpoint (CEP) consisting of cardiovascular death, nonfatal stroke or nonfatal myocardial infarction were investigated. RESULTS: The beneficial effect of losartan versus atenolol-based treatment was greater in the group of patients older than 67 years [hazard ratio 0.79 (0.69-0.91), Pâ=â0.001] compared to the group of patients younger than 67 years [hazard ratio 1.03 (0.82-1.28), Pâ=â0809], Pâ=â0.045 for interaction. The beneficial effects of losartan versus atenolol-based antihypertensive treatment on pulse pressure, HDL-C, UACR, and Cornell and Sokolow-Lyon voltage were not more pronounced in patients older than 67 years compared to patients younger than 67 years. All five risk factors considered as time-varying covariates predicted CEP independently (Pâ<â0.01) with the exception of pulse pressure (Pâ=â0.37) and the interaction between age and treatment on outcome remained significant (Pâ=â0.042). CONCLUSIONS: We showed a greater beneficial effect of losartan versus atenolol-based antihypertensive treatment in the group of patients older than 67 years compared to the group of patients younger than 67 years. This difference was not explained by a more pronounced effect of losartan-based treatment on any of the cardiovascular risk factors demonstrated to have independent prognostic importance.
