Trendelenburg position does not increase cross-sectional area of the internal jugular vein of the obese patients

Background and Aim: Obesity is one of the health issues that recently increasing worldwide result increased health care. Venous access is one of the important issues for surgical obese patients. A central venous catheter may be necessary if there is difficulty of finding a viable peripheral venous access in the operative setting. Trendelenburg positioning is a common approach used during internal jugular vein (IJV) cannulation. No evidence indicates that Trendelenburg positioning significantly increases the cross-sectional area (CSA) of the IJV in obese patients. The primary aim of this study was to determine the effectiveness of Trendelenburg positioning on the CSA of the right internal jugular vein assessed by ultrasound measurement in obese patient.
