Most guidelines fail to specify patient positioning during central venous catheterization. The
objective was to determine the effects of head‐down tilt (Trendelenburg position) and head …

To determine the effect of Trendelenburg position on the diameter or cross-section area of
the internal jugular vein (IJV) a systematic review and metanalysis was performed. Studies …

Aims: The aim of this study is to determine the head-down tilt angle, which ensures the
absence of the respiratory-based IJV excursion. Subjects and Methods: Prospective study …

OBJECTIVE: Central venous access remains a cornerstone procedure for a variety of clinical
conditions. Ultrasound studies suggest that rotation of the head increases the magnitude of …

Optimal head rotation angle for safe right internal jugular vein catheterization using out-of-plane
approach: an ultrasonography Page 1 Med Ultrason 2019, Vol. 21, no. 4, 435-440 DOI: Original …

Background The Trendelenburg position is used to distend the central veins, improving both
the success and safety of vascular cannulation. The purpose of this study was to measure …

Background: Central venous cannulation is an invasive procedure commonly used by many
physicians. The aim of this study was to evaluate the effects of the right lateral tilt position on …

Objectives The aim of this study was to determine the degree of head rotation that creates
the maximal anatomic separation between the right internal jugular vein and the carotid …

We undertook a prospective laboratory study to examine the effect of head position on the
relative positions of the carotid artery and the internal jugular vein (IJV). Volunteers (n= 12) …

BACKGROUND This study evaluated the position and relationship between the right internal
jugular vein (IJV) and the surrounding external landmarks using ultrasonography …
