Ultrasound Guidance vs Landmark Technique for Internal Jugular Vein Catheterization

Central venous catheterization (CVC) is a fundamental procedure in anesthesiology and reanimation practice for critical clinical processes such as hemodynamic monitoring, vasoactive drug infusion, and fluid resuscitation. The internal jugular vein (IJV) is frequently preferred due to its superficial anatomical location and ease of access. This study aims to observe and compare the ultrasound (USG) guidance and the landmark method in patients scheduled for IJV catheterization.
