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.
Traditionally, IJV catheterization applied with a blind technique based on anatomical landmarks is increasingly being replaced by USG-guided applications. However, the landmark method is still actively and widely used in the field due to equipment limitations or practical habits. A total of 144 patients aged 18-75 who are operated on in the general operating room unit and have a central venous catheter inserted will be included in this prospective study. Patients will be divided into two groups: those receiving USG-guided catheterization (n=72) and those receiving the landmark technique (n=72). All patients will receive standard general anesthesia after an 8-hour fasting period. The physician performing the cannulation with USG will have at least 2 years of USG experience and/or a certificate.

The study population consists of patients aged 18 to 75 years who are scheduled to undergo surgery in the general operating room unit at Dicle University Faculty of Medicine Hospital and require the insertion of a central venous catheter. All included patients will receive standard general anesthesia following an 8-hour fasting period
