Prehospital airway management using the laryngeal tube : An emergency department point of view.
Competence in airway management and maintenance of oxygenation and ventilation represent fundamental skills in emergency medicine. The successful use of laryngeal tubes (LT, LT-D, LTS II) to secure the airway in the prehospital setting has been published in the past. However, some complications can be associated with the use of a laryngeal tube. ⋯ Although the laryngeal tube is considered to be an effective, safe, and rapidly appropriable supraglottic airway device, it is also associated with adverse effects. In order to prevent tongue swelling, after initial prehospital or in-hospital placement of laryngeal tube and cuff inflation, it is important to adjust and monitor the cuff pressure.

Previous studies have suggested that when using several emergency systems and air rescue prehospital and on-scene times are extended, depending on the dispatch strategy. Emergency medical services (EMS) in Germany are delivered by ambulances (AMB) staffed by paramedics alone or with physicians (EMD) and by helicopter emergency medical services (HEMS) always staffed by both. The advantages of HEMS in countries with short transport distances and high hospital density are controversial. The best dispatching strategy for HEMS has not been determined ⋯ OST varies significantly depending on the number of EMS involved and the dispatch strategy. Sequential dispatching of ground and later HEMS wastes time. Getting an emergency physician to the scene as quickly as possible, reducing transport time to an appropriate hospital and caring for more complex emergencies are the main indications for HEMS. If HEMS appears likely to be needed, it should be dispatched immediately.

Securing the airway using a tube exchanger catheter is an important and useful technique in anesthesia. Its success is mainly hampered by tube tip impingement of laryngeal structures. Advancing the tracheal tube along its normal curvature via a tube exchanger catheter has a high risk of tube tip impingement mainly of right laryngeal structures. The authors achieved successful clinical experience by rotating the tracheal tube 90° anticlockwise (ventral tube tip position) before railroading the tube via a tube exchanger catheter or a fiber optic bronchoscope through the larynx. ⋯ Tube insertion via an airway exchange catheter or a fiberoptic bronchoscope is a basic technique in anesthesia. Knowledge about the difficulties and their prevention are essential for every anesthetist. The gap between the airway exchange catheter, the fiber bronchoscope and the tube diameters is one of the major reasons for tube tip impingement. This investigation showed that intubation success via a tube exchange catheter, as investigated in an intubation mannequin, is considerably influenced by the tracheal tube tip position. A 90° anticlockwise rotation, placing the tracheal tube tip ventrally, considerably increased intubation success. This is of particular importance if an anesthesia department has no appropriately sized tube exchange catheters or fiber bronchoscope for every age group of patients.

A uvular edema can be associated with angioedema, urticaria and anaphylaxis. Furthermore, it can be caused by medications, such as angiotensin-converting enzyme (ACE) inhibitors, non-steroidal anti-inflammatory drugs and angiotensin II receptor antagonists. ⋯ This article presents the case of a patient who underwent kidney transplantation and developed extensive edema of the uvula that occurred postoperatively after general anaesthesia. The case report describes the diagnosis and therapy of this rare disease.
