INTRODUCTION Benzodiazepines and alpha2 adrenoceptor agonists exert opposing effects on innate immunity and mortality in animal models of infection. We hypothesized that sedation with dexmedetomidine (an alpha2 adrenoceptor agonist), as compared with lorazepam (a benzodiazepine), would provide greater improvements in clinical outcomes among septic patients(More)
INTRODUCTION Non-intensive care unit (ICU) cohorts have shown an association between inflammatory disturbances and delirium, though these relationships have not been studied in critically ill patients. This study sought to investigate the relationship between two inflammatory biomarkers, procalcitonin and C-reactive protein (CRP), and duration of acute(More)
Critically ill patients are frequently prescribed sedatives and analgesics to ensure patient safety, to relieve pain and anxiety, to reduce stress and oxygen consumption, and to prevent patient ventilator dysynchrony. Recent studies have revealed that these medications themselves contribute to worsening clinical outcomes. An evidence-based organizational(More)
Critically ill patients are routinely provided analgesia and sedation to prevent pain and anxiety, permit invasive procedures, reduce stress and oxygen consumption, and improve synchrony with mechanical ventilation. Regional preferences, patient history, institutional bias, and individual patient and practitioner variability, however, create a wide(More)
[1], we noted typographical errors in our tables and in the labelling of Figure 3. Th ere have been no changes to the results or their interpretation. In Tables 1, 2 and 3 the number of dexmedetomidine patients without sepsis should read 21 instead of the published 20. Th e numbers in the corresponding text are correct. Th e corrected tables can be found(More)
There is wide variability in the methods of follow up of patients with colorectal cancer. For the majority of patients follow up comprises regular clinical assessment and measurement of carcinoembryonic antigen (CEA) with interval colonoscopy. Regular CT examinations will additionally detect distant disease such as liver and pulmonary metastases as well as(More)
