OBJECTIVE To determine the efficacy of the Mortality in Emergency Department Sepsis (MEDS) score in the stratification of patients who presented to the emergency department (ED) with severe sepsis. METHODS Adults who presented to the ED with severe sepsis were retrospectively recruited and divided into group A (MEDS score <12) and group B (MEDS score > or =12). Their outcomes were evaluated w...

The effect of Positive End Expiratory Pressure (PEEP) on the hepatic elimination of low to moderate extraction ratio drugs has not been clearly defined. We prospectively investigated the effect of PEEP on the clearance of theophylline in 30 (20 males and 10 females) intubated critically ill adult patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). The Mean (±SD) age ...

Severity of pancreatitis is an important consideration for ED clinicians making admission judgments. The early identification of severe AP is important for the management and for improving outcomes. Validated scoring systems can be a helpful tool in this process. A multitude of predictive models has been developed to predict the severity of AP based on clinical, laboratory, and radiologic risk ...

OBJECTIVES Mortality prediction scores have been used for a long time in ICUs; however, numerous studies have shown that they over-predict mortality in the obstetric population. With sepsis remaining a major cause of obstetric mortality, we aimed to look at five mortality prediction scores (one obstetric-based and four general) in the septic obstetric population and compare them to a nonobstetr...

INTRODUCTION Despite the integral role played by tracheostomy in the management of trauma patients admitted to intensive care units (ICUs), its timing remains subject to considerable practice variation. The purpose of this study is to examine the impact of early tracheostomy on the duration of mechanical ventilation, ICU length of stay, and outcomes in trauma ICU patients. METHODS The followi...

background: an increased oxidative stress in patients under treatment with high concentrations of oxygen (hyperoxia) is considered to be one of the major mechanisms of lung injury. between different mediators, transition metal ions especially iron, by generation of very reactive free radicals play an important role in oxidative stress process. disruption of normal iron hemostasis has been repor...

introduction: deep vein thrombosis (dvt) is a major cause of morbidity and mortality in intensive care unit (icu) patients despite use of prophylactic anticoagulant therapy. the aim of the present study was to determine the incidence of dvt among medical and surgical icu patients. methods: in this cross sectional study, patients older than 18 years who were hospitalized in the icu of imam hosse...

BACKGROUND Several prognostic systems have been developed and validated in general Intensive Care Units (ICUs). No assessment of these scores was performed in specialized Gastroenterology Intensive Care Units (GICUs). AIM To assess the prognostic accuracy of Acute Physiology and Chronic Health Evaluation (APACHE) II, Simplified Acute Physiology Score (SAPS) II and Sequential Organ Failure Ass...
