Temporary transvenous pacing guided by the combined use of ultrasound and intracavitary electrocardiography: a feasible and safe technique.
Temporary transvenous pacing is a crucial procedure in emergency and critical care medicine. While fluoroscopy guidance is considered the gold-standard to place the temporary pacing electrode catheter (EC), its use is usually limited by equipment availability and time. ⋯ However, many times, in spite of visualizing the EC in the right ventricle using US, the pacing capture and sensing are not optimal, and thus, having an easily applicable method for best assessing this issue is desirable, especially if it could be combined with US without difficulties. With the purpose of illustrating the points made previously, the combined US-intracavitary electrocardiography technique is described in detail in this paper.

ReviewA narrative review of diaphragm ultrasound to predict weaning from mechanical ventilation: where are we and where are we heading?
The use of ultrasound to visualize the diaphragm is well established. Over the last 15 years, certain indices of diaphragm function, namely diaphragm thickness, thickening fraction and excursion have been established for mechanically ventilated patients to track changes in diaphragm size and function over time, to assess and diagnose diaphragmatic dysfunction, and to evaluate if these indices can predict successful liberation from mechanical ventilation. In the last 2 years, three meta-analyses and a systematic review have assessed the usability of diaphragmatic ultrasound to predict successful weaning. Since then, further data have been published on the topic. ⋯ The aim of this narrative review is to briefly describe the common methods of diaphragmatic function assessment using ultrasound techniques, before summarizing the major points raised by the recent reviews. A narrative summary of the most recent data will be presented, before concluding with a brief discussion of future research directions in this field.

Fat embolism in right internal jugular vein: incidental ultrasound finding during internal jugular vein cannulation.
We report a case study of fat embolism seen on ultrasound at right internal jugular vein during central venous cannulation in a patient diagnosed with fat embolism syndrome. This case demonstrates the importance of ultrasound for evaluation of trauma cases with suspicion of fat embolism. ⋯ Point-of-care ultrasound findings of fat embolism in central vein can facilitate and increase the suspicion of fat embolism syndrome.
