Article
Full-text available
Objective: Dynamic tests of fluid responsiveness have been developed and investigated in clinical trials of goal-directed therapy. The impact of this approach on clinically relevant outcomes is unknown. We performed a systematic review and meta-analysis to evaluate whether fluid therapy guided by dynamic assessment of fluid responsiveness compared...

Blastomyces dermatitidis is a dimorphic fungus endemic to North America capable of causing fatal respiratory failure. Acute respiratory distress syndrome (ARDS) complicates up to 10% of pulmonary blastomycosis in hospitalized patients and carries a mortality of 50-90%. This report describes the clinical course of four consecutive patients with blas...
Article
The objective of our study was to evaluate the efficacy of 24/7 in-house intensivist care for patients requiring prolonged intensive care unit (ICU) stay following cardiac surgery. A propensity-matched retrospective before-and-after observational study comparing 2 models of ICU physician staffing was undertaken. Previously, residents (with intensiv...
Article
Objectives: To explore variation in the use of diagnostic testing in ICUs, with emphasis on differences between teaching and nonteaching ICUs. Design: Retrospective review of a prospective clinical ICU database. Setting: Five teaching and four nonteaching ICUs in Winnipeg, Canada, during 2006-2010. Patients: All adults admitted to the nine I...
Article
Intensive care unit (ICU) physician staffing models for cardiac surgery patients vary widely and correlate poorly with outcomes. Clinical outcomes associated with 24-hour, in-house intensivists working in a dedicated post-cardiac surgical unit has not been previously investigated. We sought to examine the safety and efficacy of such a model. A retr...
Article
Significant progress in critical care medicine has been the result of tireless observation, dedicated research, and well-timed serendipity. This article provides a historical perspective for four meaningful therapies in critical care medicine: blood transfusion, fluid resuscitation, vasopressor/inotropic support, and antibiotics. For each therapy,...

Fluid resuscitation is a key factor in restoring hemodynamic stability and tissue perfusion in patients with severe sepsis. We sought to examine associations of the quantity and type of fluid administered in the first six hours after identification of severe sepsis and hospital mortality, intensive care unit (ICU) mortality, and organ failure. A re...
Article
This study was designed to examine the efficacy of low-dose intrathecal morphine (ITM) on extubation times and pain control after cardiac surgery. 43 patients undergoing elective cardiac surgery were enrolled in this prospective, randomized, double-blind placebo controlled trial. Patients were given a pre-induction dose of ITM (6 microg x kg(-1) pe...

Purpose This study was designed to examine the efficacy of low-dose intrathecal morphine (ITM) on extubation times and pain control after cardiac surgery. Methods 43 patients undergoing elective cardiac surgery were enrolled in this prospective, randomized, double-blind placebo controlled trial. Patients were given a pre-induction dose of ITM (6 μ...
Article
To propose a strategy for the management of patients admitted to critical care units after resuscitation from cardiac arrest. Prior to the conference relevant studies were identified via literature searches and brief reviews circulated on the following topics: glucose and blood pressure management; therapeutic hypothermia; prearrest outcome predict...
Article
Optimizing perioperative mechanical ventilation remains a significant clinical challenge. Experimental models indicate that "noisy" or variable ventilation (VV)--return of physiologic variability to respiratory rate and tidal volume--improves lung function compared with monotonous control mode ventilation (CV). VV was compared with CV in patients u...
Article
ANAPHYLAXIS is a life-threatening immunologically mediated reaction related to the administration of a substance that causes mast cell degranulation. We report a case of life-threatening anaphylaxis after topical application of bacitracin to the nasal mucosa at the conclusion of an anesthetic.
Article
To compare the utilization and cost of common laboratory and imaging tests following admission to the intensive care unit (ICU) after coronary artery bypass surgery in two hospitals. The hospitals use different strategies to order tests postoperatively: one hospital uses a mandated protocol while the other does not. Demographic and testing data wer...
Article
To identify and discriminate between patient and institutional determinants of investigation costs in the ICU. Retrospective survey. All seven hospitals in the city of Winnipeg, Manitoba, Canada. One hundred consecutive admissions to each of 11 ICUs. Two teaching hospitals (TH1 and TH2) each have three units (medical, surgical, and coronary care),...
Article
A retrospective review of consecutive admissions (n = 285) to a university hospital intensive care unit (ICU) following cardiopulmonary resuscitation was conducted to determine long-term outcome, length of stay (LOS), and ICU resource consumption. Ninety-four patients (33%) survived to hospital discharge. Hospital survivors had longer ICU LOS than...
Article
To determine if the application of an information-based management system in adult intensive care units (ICU) can produce sustained decreases in the use of laboratory resources and costs. Interventional study with prospective data collection on consecutive patients admitted during three time periods. A 10-bed adult surgical ICU and an eight-bed adu...
Article
Arterial hypoxemia, hypercapnic respiratory failure, hypotension, and depressed level of consciousness are the usual reasons for admitting a patient with pneumonia to an intensive care unit (ICU). Once the decision has been made to manage the patient in the ICU, age has little effect on the immediate goals of therapy, which include correction of hy...
Article
A 20-yr-old man is described with the rare presentation of antibasement membrane antibody (ABMA) disease confirmed on renal biopsy, but with normal renal function and urinary sediment. This distinct subgroup of ABMA appears to have an excellent prognosis. The relevant literature is reviewed and summarized.
