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)
We developed a screening questionnaire to be used by nurses to decide which patients should see an anaesthetist for further evaluation before the day of surgery. Our objective was to measure the accuracy of responses to the questionnaire. Agreement between questionnaire responses and the anaesthetist's assessment was assessed. For questions with a(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)
BACKGROUND To transfuse blood products safely, health care workers must accurately identify patients, blood samples, and the blood components. A comprehensive bar code-based computerized tracking system was developed and implemented to identify and prevent transfusion errors. STUDY DESIGN AND METHODS A data network, wireless devices, and bar-coded labels(More)
graphical 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 overleaf. In Figure(More)
PURPOSE OF REVIEW The autonomic nervous system functions to control heart rate, blood pressure, respiratory rate, gastrointestinal motility, hormone release, and body temperature on a second-to-second basis. Here we summarize some of the latest literature on autonomic dysfunction, focusing primarily on the perioperative implications. RECENT FINDINGS The(More)
Therapeutic hypothermia has been shown to be effective in out-of-hospital cardiac arrest, and use of this therapy has been expanded to involve in-hospital cardiac arrest. The utility of hypothermia in cardiac arrest after hemorrhage is not known. We describe a case of successful neurological and functional outcome after in-hospital pulseless electrical(More)
The use of transesophageal echocardiography (TEE) for resuscitation after burn injury has been reported in small case studies. Conventional TEE is invasive and often requires a subspecialist with a high level of training. The authors report a series of surgeon-performed hemodynamic TEE with an indwelling, less bulky, user-friendly probe. Records of patients(More)
