The authors describe the special tracheal intubation technique used in two patients with a difficult airway. These are the translaryngeal retrograde wire-guided and fiberoptic intubation. The authors show how to use both to facilitate intubation. The authors modified the technique by passing a guide-wire in a retrograde manner from the trachea to the nose and then a fiberoptic laryngoscope with...

Central venous catheter (CVC) placement is an essential component of modern-day critical care. Its use was first documented by Werner Forssman in 1929, and Seldinger perfected the technique in 1953.(1) Although CVC insertion is a routine practice, it is not devoid of complications. We report a rare event in which the introducer needle shaft was fractured from its hub during CVC insertion in the...

We present a method to suppress the roughness of the potential of a wire-based, magnetic atom guide: modulating the wire current at a few tens of kHz, the potential roughness, which is proportional to the wire current, averages to zero. Using ultracold 87Rb clouds, we show experimentally that modulation reduces the roughness by at least a factor five without measurable heating or atom loss. Thi...

In neuro-interventional surgeries, physicians rely on fluoroscopic video sequences to guide tools through the vascular system to the region of interest. Due to the low signal-to-noise ratio of low-dose images and the presence of many line-like structures in the brain, the guide-wire and other tools are difficult to see. In this work we propose an effective method to detect guide-wires in fluoro...
