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.

In this study, the subjects are divided into two groups (group I: intervention group = the nasotracheal tube inserted with the bevel of the nasal tube facing the direction of the patient's...
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...
We have performed quantum-based molecular dynamics (MD) simulations in conjunction with multiscale shock technique (MSST) to investigate the initial chemical processes and the anisotropy of shock sens...
When perforated by a projectile, sandwich bones typically exhibit wounds with a distinct conoidal morphology that is widely utilised both in wound diagnosis and trajectory determinations. However, the...
Research is described that determines the direction that a powered wheelchair will take, using the Preference Ranking Organization METHod for Enrichment of Evaluations II (PROMETHEE II). This is the f...
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...
High-tech simulators are gaining popularity in surgical training programs because of their potential for improving clinical outcomes. However, most simulators are static in nature and only represent a...
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)
