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 …

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 …

Introduction The anatomy of the internal jugular vein (IJV) may be influenced by the position
of the patient. A head‐down‐tilt or Trendelenburg position could potentially increase the size …

Background: Obese subjects are considered to be a difficult group for central vein
cannulation. We investigated the optimal position for right internal jugular vein (IJV) …

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 …

Background Cannulation of the internal jugular vein may be associated with inadvertent
puncture of the common carotid artery. Systematic use of ultrasound guidance has improved …

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 …

METHODS We recruited 100 American Society of Anesthesiologists physical status class I
patients aged 2–12 years. The patients' heart rate, blood pressure, peripheral oxygen …

INTRODUCTION Complications occur in over 15% of central venous cannulations, often a
result of anatomical variations. This study aimed to determine the anatomical variations of …

INTRODUCTION: The right internal jugular vein is commonly preferred for securing central
venous access, and success of cannulation shows a positive correlation with veins diameter …
