Objective: We studied an ultrasound sign, the fleeting appearance of a lung pattern (lung sliding or pathologic comet-tail artifacts) replacing a pneumothorax pattern (absent lung sliding plus exclusive horizontal lines) in a particular location of the chest wall. This sign was called the "lung point". Design: Prospective study. Setting: The medical ICU of(More)
OBJECTIVES Pneumothorax can be missed by bedside radiography, and computed tomography is the current alternative. We asked whether lung ultrasound could be of any help in this situation. DESIGN Retrospective study. SETTING The medical intensive care unit of a university-affiliated teaching hospital. PATIENTS All patients admitted to the intensive care(More)
Objective: Ultrasound artifacts arising from the lung–wall interface are either vertical (comet-tail artifacts) or horizontal. The significance of these artifacts for the diagnosis of pneumothorax was assessed. Design: Prospective clinical study. Setting: The medical ICU of a university-affiliated teaching hospital. Patients: We compared 41 complete(More)
Can ultrasound be of any help in the diagnosis of alveolar-interstitial syndrome? In a prospective study, we examined 250 consecutive patients in a medical intensive care unit: 121 patients with radiologic alveolar-interstitial syndrome (disseminated to the whole lung, n 5 92; localized, n 5 29) and 129 patients without radiologic evidence of(More)
BACKGROUND The risk of pulmonary edema is the main limiting factor in fluid therapy in the critically ill. Interstitial edema is a subclinical step that precedes alveolar edema. This study assesses a bedside tool for detecting interstitial edema, lung ultrasound. The A-line is a horizontal artifact indicating a normal lung surface. The B-line is a kind of(More)
BACKGROUND Antibiotic prophylaxis is recommended in cardiac surgery. Current debate concerns the type of antibiotic(s), dosing and the duration of prophylaxis. METHODS Systematic review of randomized controlled trials comparing one antibiotic regimen versus another in cardiac surgery. We searched The Cochrane Library, PubMed, LILACS, conference(More)
BACKGROUND The use of extracorporeal life support in trauma casualties is limited by concerns regarding hemorrhage, particularly in the presence of traumatic brain injury (TBI). We report the use of extracorporeal membrane oxygenation (ECMO)/interventional lung assist (iLA) as salvage therapy in trauma patients. High-flow technique without anticoagulation(More)
INTRODUCTION/OBJECTIVE Heat stroke (HS) is a common medical emergency which carries high morbidity and morality. This study was designed to describe the pattern of central nervous system (CNS) changes as detected by brain CT scan in a case series of six patients suffering from classical and exertional HS. METHODS AND PATIENTS All the patients were(More)
