Intubating and non-intubating supraglottic airways (LMA) for neonates and children are an important tool for managing the emergency pediatric airway. Depending on the product, they have unique features that can help facilitate BVM ventilation, provide gastric suctioning, or allow for intubation directly or over a bronchoscope. Learn how to use the air-Q LMA, LMA Supreme, LMA Fastrach and how they can be incorporated as a critical part of your pediatric airway algorithm.
Understand the workings and tips for best use of ECMO ultrasonic sensors. ECMO centrifugal flow pumps require external sensors to provide accurate measurement of blood flow rates based on differential acoustic transit time due to the Doppler effect. The acoustic mirror of bubbles allow for easy detection of air in the line also.
Prone positioning in ARDS can improve lung compliance and ventilation-perfusion matching which improve oxygenation and may have a mortality benefit. It requires significant effort and staff coordination to perform safely and efficiently. In this article we include tips for preparation, and a detailed checklist for performing proning efficiently and safety.
With centrifugal flow pumps, the ECMO circuit blood flow rate is dependent not only on the pump rotational speed, but also upstream and downstream pressures. Ultrasonic flow transducers provide are able to provide accurate measurements. The ECMO ultrasound flow sensors require a conductive interface between the sensor and the circuit.
Malignant hyperthermia is a life-threatening reaction to volatile anesthetics and the neuromuscular blocking agent succinylcholine, which results in high body temperatures. Dantrolene counters the reaction by blocking the release of calcium from the sarcoplasmic reticulum, and reducing the intracellular calcium.
Hemorrhage is a feared and potentially life-threatening complication following catheterization. This may reflect retroperitoneal hemorrhage, pericardial bleeding including cardiac tamponade, gastrointestinal, intracranial, or hemolysis. However, there can also be benign or procedural causes.
Gas exchange in vv-ECMO is effected by four critical factors. There needs to be adequate effective ECMO blood flow compared to cardiac output and minimal recirculation. Oxygenation can then be set with the blender and carbon dioxide removal is determined by the sweep gas flow rate.
