To test the hypothesis that approaching the internal jugular vein with the needle bevel down would produce less injury to the vessel wall compared to the bevel up approach during central venous catheterization.

40000 patients are hemodialysis each year in France . In the case of chronic care, 78% of patients have an arteriovenous fistula. In order to perform the hemodialysis session, 2 technique...
Ultrasound (US)-guided central venous catheterization is now considered standard of care according to recent clinical evidence, at least considering jugular vein approach. Recent trials su...
The purpose of this study is to compare the differences in central venous catheter insertion time, success rate, and complication between the Seldinger and modified Seldinger technique for...
Total of 89 patients undergoing elective cardiac surgery will be enrolled. Right CVC insertion begins at their intersection of the cricoid cartilage level and the triangular point where t...
The anatomy and ultrasound image of infraclavicular region was investigated on cadavers and healthy volunteers, respectively. Structures，route，position and complications were discussed ...
Participant direction allows people with intellectual and developmental disabilities (IDD) and/or their families to direct services; in doing so, participant direction shifts participants from passive...
Visualizing the needle tip using the short-axis (SA) ultrasound-guided central venous catheterization approach can be challenging. It has been suggested to start the process with the SA approach and t...
The insertion of a central venous line in children and adolescents is technically more difficult, due to the smaller size of the structures. This can lead to an increase in immediate complications, wh...
Direction selectivity is a fundamental computation in the visual system and is first computed by the direction-selective circuit in the mammalian retina. While landmark discoveries on the neural basis...
Seeing the direction of motion is essential for survival of all sighted animals. Consequently, nerve cells that respond to visual stimuli moving in one but not in the opposite direction, so-called 'di...
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life.

Surgical reshaping of the gingivae and papillae for correction of deformities (particularly enlargements) and to provide the gingivae with a normal and functional form, the incision creating an external bevel. (Dorland, 28th ed)
Flaps within the VEINS that allow the blood to flow only in one direction. They are usually in the medium size veins that carry blood to the heart against gravity.
Misalignment of the visual axes of the eyes. In comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. In noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target. (Miller, Walsh & Hoyt's Clinical Neuro-Ophthalmology, 4th ed, p641)
