AI Article Synopsis
Article Abstract
Before percutaneous tracheostomy, rabbits were anesthetized and placed in the supine position with the head extended. A needle cricothyroidotomy was then performed. With the help of a guidewire and vessel dilator, a sheath introducer with sideport extension was secured into the airway. This system provided airway access for introduction or sampling of materials while the animal was breathing around the sheath introducer or through the sideport. This simple procedure was used successfully in more than 25 rabbits that recuperated and lived for several days without ongoing medical support.

Introduction: Hemorrhage is the leading cause of preventable deaths in trauma patients, resulting in 1.5 million deaths annually worldwide. Traditional trauma assessment follows the ABC (airway, breathing, circulation) sequence; evidence suggests the CAB (circulation, airway, breathing) approach to maintain perfusion and prevent hypotension.

There is a lack of clear guidance on whether to retain or remove a previously inserted supraglottic airway device (SAD) before eFONA. We aimed to study the effect of both neck extension and insertion of an SAD on sagittal cricothyroid membrane (CTM) height.

Nasal adhesions, or synechiae, commonly occur following surgical procedures, resulting in nasal airway obstruction and patient discomfort. While various packing materials are available to prevent adhesion formation post-surgery, there is limited guidance on effectively dividing existing adhesions and determining the optimal packing materials to maintain separation afterward. We treated a 59-year-old man with severe adhesions in the anterior nasal cavity.

Background: High-flow nasal cannula (HFNC) therapy has developed as a valuable tool for respiratory support in pediatric critical care. It offers an intermediate level of support between traditional low-flow oxygen and non-invasive ventilation (NIV). Studies suggest its effectiveness in improving oxygen delivery, work of breathing, and secretion clearance.

Background: The insertion of a tracheostomy is an established technique used to wean patients off ventilatory support, manage secretions in complex conditions, and as a potentially life-saving procedure to bypass upper airway obstruction. Life-threatening complications during aftercare are not uncommon and may be influenced by a lack of education of carers or healthcare providers of children and young people living with a tracheostomy. Education programmes designed and supported by the National Tracheostomy Safety Project are effective, but resources are not available to educate the workforce at scale.
