Ultrasound Guided Vascular Access

This is a prospective randomized clinical trial aiming to compare the success rate, complications, and insertion time between ultrasound-guided brachiocephalic vein (BCV) and internal jugular vein (IJV) cannulation in mechanically ventilated patients in the intensive care unit (ICU). The goal is to determine whether BCV access offers a safer or more effective alternative in critically ill patients requiring central venous catheter placement.
