Video-based, student tutor- versus faculty staff-led ultrasound course for medical students - a prospective randomized study.

Background: Ultrasound education is propagated already during medical school due to its diagnostic importance. Courses are usually supervised by experienced faculty staff (FS) with patient bedside examinations or students among each other but often overbooked due to limited FS availability. To overcome this barrier, use of teaching videos may be advantageous.

[Ultrasound visualization of the guidewire and positioning of the central venous catheter : A prospective observational study].

Background: After insertion of a central venous catheter (CVC) the catheter position must be controlled and a pneumothorax ruled out.

Objective: The aim was to examine whether the use of two standard acoustic windows known from emergency sonography examination techniques is feasible to 1) verify the correct intravenous localization and direction of the guidewire before final CVC insertion and 2) correctly predict the required CVC length for positioning of the catheter tip in the lower third of the superior vena cava.

Material And Methods: This single center prospective observational study included adult patients (age ≥18 years) with an indication for CVC insertion after institutional ethics approval was obtained.

Why Asplenic Patients Should Not Take Care of the Neighbour's Dog? A Fatal Course of Sepsis.

(CC) belongs to the family Flavobacteriaceae which physiologically occurs in the natural flora of the oral mucosa of dogs and cats. In patients with a compromised immune system, CC can induce a systemic infection with a fulminant course of disease. Infections with CC are rare, and the diagnosis is often complicated and prolonged.

Determination of respiratory system compliance during pressure support ventilation by small variations of pressure support.

In mechanically ventilated patients, measurement of respiratory system compliance (C) is of high clinical interest. Spontaneous breathing activity during pressure support ventilation (PSV) can impede the correct assessment of C and also alter the true C by inducing lung recruitment. We describe a method for determination of C during PSV and assess its accuracy in a study on 20 mechanically ventilated patients.

Assessment of respiratory system compliance with electrical impedance tomography using a positive end-expiratory pressure wave maneuver during pressure support ventilation: a pilot clinical study.

Introduction: Assessment of respiratory system compliance (Crs) can be used for individual optimization of positive end-expiratory pressure (PEEP). However, in patients with spontaneous breathing activity, the conventional methods for Crs measurement are inaccurate because of the variable muscular pressure of the patient. We hypothesized that a PEEP wave maneuver, analyzed with electrical impedance tomography (EIT), might be suitable for global and regional assessment of Crs during assisted spontaneous breathing.
