We demonstrate and discuss a liquid pumping effect based on the interaction between periodically generated cavitation microbubbles and a millimeter diameter tube. The bubbles are generated by the heat of laser adsorption at the tip of an optical fiber immersed in liquid. When the bubbles are generated well away from the tube, a steady streaming flow with a relatively large and energetic ring vo...

Mechanical ventilation with an endotracheal tube is frequently used in the ICU setting (including paediatric ICUs, or PICUs). Although complications seldom occur, they can be life-threatening. We report on the case of a 10-year-old boy who developed pneumomediastinum and extensive subcutaneous emphysema due to severe tube obstruction caused by kinking of the endotracheal tube. The kinking proba...

Nasotracheal intubation should be performed in patients with jaw fractures because maxillomandibular fixation is required. However, when there are concomitant fractures of the nose and facial bones, an intubation tube positioned at the nose makes it difficult to perform an intricate surgery. In order to overcome these problems, a variety of ways to change the position of the tube have been intr...

During insertion of the double lumen tube in patients with ankylosing spondylitis, cervical neutral position should be maintained to avoid vertebral and spinal injuries. Although flexible fiberoptic bronchoscopic intubation is the gold standard, available FOB size is not compatible with that of the endobronchial lumen of the double lumen tube. This problem should be solved according to institut...

Methods This study was conducted on 100 patients who were admitted to Critical Care Medicine Department in Alexandria Main University Hospital with an indication of endotracheal tube placement. All patients were examined by ultrasonography “linear probe” after endotracheal tube insertion. Results were compared with capnometric readings (end tidal CO2). After confirmation of endotracheal tube po...

BACKGROUND Nasogastric tube insertion may be difficult in anesthetized and intubated patients with head in the neutral position. Several techniques are available for the successful insertion of nasogastric tube. The primary aim of this study was to investigate the difference in the first attempt success rate of different techniques for insertion of nasogastric tube. Secondary aim was to investi...

A 14 year-old adolescent with achondroplasia and Jeune's syndrome (asphyxiating thoracic dystrophy) presented for cervical spine surgery in the prone position. Due to the need for home mechanical ventilation at night, the patient had a tracheostomy in place. With the first surgical procedure, the cuffed tracheostomy tube was left in place during prone positioning. Difficulties encountered with ...

RAPID and accurate diagnosis of the misplacement of an endotracheal tube in the esophagus remains one of the most important problems in anesthesia and intensive care. Clinical signs observed through auscultation, inspection of thoracic excursions, refilling of the breathing bag, or water vapor condensing at the endotracheal tube may be misleading in as many as 30% of patients. ' Although end-ti...
