OBJECTIVE In a recent randomized controlled trial, lowering blood glucose levels to 80-110 mg/dl improved clinical outcomes in critically ill patients. In that study, the insulin infusion protocol (IIP) used to normalize blood glucose levels provided valuable guidelines for adjusting insulin therapy. In our hands, however, ongoing expert supervision was(More)
Strict glycemic control improves clinical outcomes in critically ill patients. However, practical tools for frequent monitoring of blood glucose (BG) levels in the intensive care unit (ICU) are limited. The Continuous Glucose Monitoring System (CGMS, Medtronic MiniMed, Northridge, CA) is currently approved for detecting glycemic excursions in outpatients(More)
RATIONALE Microvascular injury, inflammation, and coagulation play critical roles in the pathogenesis of acute lung injury (ALI). Plasma protein C levels are decreased in patients with acute lung injury and are associated with higher mortality and fewer ventilator-free days. OBJECTIVES To test the efficacy of activated protein C (APC) as a therapy for(More)
The intensivist should think of delirium, or acute central nervous system dysfunction, as the brain's form of "organ dysfunction.'' Delirium is extremely common in intensive care unit (ICU) patients due to factors such as comorbidity, critical illness, and iatrogenesis. This complication of hospital stay is extremely hazardous in older persons and is(More)
Imaging in the ICU plays a crucial role in patient care. The portable chest radiograph (CXR) is the most commonly requested radiographic examination, and, despite its limitations, it often reveals abnormalities that may not be detected clinically. Recent advances in CT technology have made it possible to obtain diagnostic-quality images even in the most(More)
The vascular growth factor angiopoietin 2 (Ang-2) is known to promote inflammation and endothelial dysfunction, but its prognostic capacity and relationship to outcomes in human sepsis are unknown. This is a prospective observational cohort study of 66 patients newly admitted to a tertiary care medical intensive care unit (ICU), which included ICU patients(More)
BACKGROUND The diagnosis of esophageal atresia may be suspected on prenatal ultrasound scan in fetuses with a small or absent stomach or unexplained polyhydramnios. However, these findings are thought to have a low positive predictive value and clinical decisions affecting timing or site of delivery may be made erroneously. The authors evaluated the(More)
OBJECTIVES To determine the rates of psychiatric illness in next of kin following the death of a relative in a medical intensive care unit. DESIGN Cross-sectional survey. SETTING A university teaching hospital, New Haven, CT. PATIENTS Forty-one next of kin who had served as primary surrogate decision makers before the death of their loved one in the(More)
BACKGROUND Safe and timely oral alimentation is crucial for optimum patient care. OBJECTIVE To determine the short-term success of recommending specific oral diets, including drinking thin liquids, to acute care hospitalized patients at risk for dysphagia based on passing a 3-ounce water swallow challenge protocol. DESIGN Prospective single group(More)
