The Seeing Stylet: a new device for tracheal intubation

The Clarus Video System as a useful diagnostic tool

“…We agree with Dr Narouze that it is advisable to perform a prescan before performing a stellate ganglion block to familiarise oneself with the relevant anatomy, using colour flow Doppler to detect any vessels and plan a safe path for the needle whether inserted in-plane or out-ofplane [2].…”

“…1). Similar to other stylets [2][3][4], it can be inserted in a conscious and co-operating patient with only mild discomfort, easily managed with topical anaesthesia and minimal sedation.…”

“…Peng and Narouze have outlined the differences in endpoints between the blind stellate block and those performed under fluoroscopic and ultrasound guidance [2]. Using fluoroscopy, a needle may be accurately directed towards Chassaignac's tubercle.…”

“…However, this bony landmark is a surrogate marker for the stellate ganglion, generally being closer to the middle cervical ganglion. The ultrasound method uses the prevertebral fascia as its endpoint [2]. This fascia lies over the vertebral bodies, their anterior transverse processes, the longus colli, capitis and anterior scalene muscles.…”

Initial anatomic investigations of the I‐gel airway: a novel supraglottic airway without inflatable cuff*

“…Endoscopy was performed by sliding a malleable, high resolution, optical stylet (Seeing Optical Stylet, Clarus Medical, Minneapolis, MN) down the main lumen of the I-gel after placement [9]. An endoscopic camera (MedCam Pro, MedCam Technologies, Sunrise, FL) was mounted on the eyepiece of the stylet and the image from the camera was digitally recorded (Sony GDV-900 mini-DV deck, Sony Corporation, Tokyo, Japan).…”
