High Voltage and Train-Surfing Injuries: A 30-Year Retrospective Analysis of High-Voltage Trauma and Its Impact on Cardiac Biomarkers.

: High-voltage electrical injuries (HVEIs) represent a complex and life-threatening entity, frequently involving multi-organ damage. While traditionally linked to occupational hazards, train surfing-riding on moving trains-and train climbing-scaling stationary carriages-have emerged as increasingly common causes among adolescents. Popularized via social media, these behaviors expose individuals to the invisible danger of electric arcs from 15,000-volt railway lines, often resulting in extensive burns, cardiac complications, and severe trauma.

Non-occlusive mesenteric ischaemia: the prevalent cause of gastrointestinal infarction in patients with severe burn injuries.

Background: Gastrointestinal complications occur frequently in intensive care patients with severe burns. Intestinal infarction and its deleterious consequences result in high mortality despite rapid surgical intervention. Our objective was to evaluate the aetiology of gastrointestinal infarction in intensive care patients with severe burns.

Development of demographics and outcome of very old critically ill patients admitted to intensive care units.

Purpose: To evaluate the development of demographics and outcome of very old (>80 years) critically ill patients admitted to intensive care units.

Setting: All consecutive patients admitted to 41 Austrian intensive care units (ICUs) over an 11-year period.

Methods: We performed a retrospective cohort study of prospectively collected data.

Intrinsic positive end-expiratory pressure at various frequencies of supraglottic jet ventilation in a model of dynamic upper airway obstruction.

Background: Supraglottic jet ventilation (JV(S)) with injectors above airway stenoses may result in inadvertent high lung pressures. We designed this study to investigate intrinsic positive end-expiratory pressure (PEEP(i)) during jet ventilation via a distant injector in a model of dynamic upper airway obstruction.

Methods: Respiratory pressure-time curves were recorded during JV(S) in a tracheal lung model using a pig's trachea and an embolectomy catheter's air-filled balloon to simulate 60 and 80% airway obstruction.

Airway stenosis-related increase of pulmonary pressure during high-frequency jet ventilation depends on injector's position.

Background: High-frequency jet ventilation (HFJV) can lead to high-airway pressures under certain conditions. In this laboratory study, we evaluated the influence of the injector's position relative to a fixed airway obstruction on peak pressures in a tracheal-lung model.

Methods: We administered HFJV via a metal jet injector at varying distances from connectors simulating laryngotracheal airway stenosis.
