For internal jugular vein (IJV) central venous cannulation using the central approach, the needle is directed toward which surface landmark?
- A Ipsilateral anterior superior iliac spine
- B Ipsilateral nipple at a 45° angle ✓
- C Sternal notch (jugular notch)
- D Contralateral nipple
Explanation
In the central approach to IJV cannulation, the needle is inserted at the apex of the triangle formed by the two heads of sternocleidomastoid and the clavicle, directed toward the ipsilateral nipple (at approximately 30–45° to the skin). This angles the needle inferolaterally toward the confluence of IJV and subclavian vein. Directing toward the sternal notch risks carotid artery puncture. The landmark is used with ultrasound guidance in current practice to reduce complications.
