Abstract Background This study evaluated the ability of diaphragmatic excursion (DE), measured 2 h after extubation, to predict need for resumption ventilatory support within 48 in surgical critically ill patients. Methods prospective observational included adult patients intubated > 24 and extubated a successful spontaneous breathing trial. Sonographic measurement DE was performed extubation. Patients were followed up extubation divided into reintubation group weaning group. The primary...

The prevalence of extensively drug resistant gram negative bacilli (XDR-GNB) is rapidly progressing; however in Egypt data are sparse. We conducted the present study to quantify incidence, risk factors and outcome patients harboring XDR-GNB.A one year prospective was done by collecting all bacteriological reports for cultures sent from surgical intensive care unit, Cairo university teaching hospital. XDR-GNB were defined as any three or more classes antimicrobial agents. Patients with...

Academic self-efficacy (ASE), influenced by various sociodemographic, lifestyle, and psychological factors, is a critical determinant of academic performance in medical students. In Egypt, the education system underwent recent drastic changes. Therefore, we aim to explore effects these changes on variables above and, subsequently, ASE among national sample Egyptian We conducted cross-sectional study across 30 colleges using validated electronic Arabic survey evaluate lifestyle behaviors,...

<h3>BACKGROUND:</h3> Sepsis-induced diaphragmatic dysfunction is one of the main risk factors failure to liberate patients from mechanical ventilation. Several studies addressed ultrasound as a valuable tool in assessment function during liberation ventilation different populations. However, none these examined use predict subjects with sepsis <h3>METHODS:</h3> A prospective observational study was done on and abdominal sepsis. The thickening fraction, excursion, rapid shallow breathing...

The outcome of patients in septic shock has been shown to be related changes within the microcirculation. Modern imaging technologies are available generate high resolution video recordings microcirculation humans. However, evaluation is not yet implemented routine clinical monitoring critically ill patients. This mainly due large amount time and user interaction required by current analysis software. aim this study was validate a newly developed automated method (CCTools®) for...

Abstract Background Intradialytic hypotension is a serious complication during renal replacement therapy in critically ill patients. Early prediction of intradialytic could allow adequate prophylactic measures. In this study we evaluated the ability peripheral perfusion index (PPI) and heart rate variability (HRV) to predict hypotension. Methods A prospective observational included 36 patients with acute kidney injury their first session intermittent hemodialysis. addition basic vital signs,...

Prediction of fluid responsiveness (FR) is a critical step in management patients with septic shock. Using ultrasound detection inferior vena cava (IVC) diameters and collapsibility established mechanically ventilated patients; however its use spontaneous breathing still controversial [1]. Few studies reported correlation between internal jugular vein dimensions central venous pressure (CVP) [2, 3] but no data are available about the IJV FR.

According to the product information for parenteral paracetamol, fewer than 1% of patients will have more severe adverse effects like hypotension. However, a number studies suggest that prevalence paracetamol induced hypotension may be higher drug's producers.
