Comparison between landmark and ultrasound-guided techniques for internal jugular vein cannulation: A prospective observational study.

Internal jugular vein cannulation still has complications especially with landmark (LM) technique where no imaging used. Therefore, it is of interest to compare ultrasound-guided (USG) and LM techniques in 70 patients. USG group showed better first-attempt success, shorter flash time, faster cannulation and less complication. Arterial puncture, hematoma, pneumothorax and catheter displacement were seen only in LM group proving USG safer and faster for central venous access.
