Answer 1

Seldinger technigue

Question 2

Answer 2

it punctures the vessel

Question 3

Who developed the Seldinger technique and when?

Answer 3

Sven Ivan Seldinger 1953

Question 4

This technique involves the use of the needle, guidewire, catheter

Answer 4

Seldinger Technique

Question 5

Enumerate all the steps in the Seldinger Technique

Answer 5

1. Record all pulses & blood pressure of both extremities
2. The peripheral vessels are palpated and their pressures recorded
3. Site is cleaned & area draped
4. Physician administers a local anesthetic in the perivascular tissue
5. Local Anesthesia, use 2 ml syringe & 2% lidocaine
6. Small incision of about 2mm is made in the skin approx. 1-2cm below the intended puncture site
7. Needle is placed in the incision 7 artery is located
8. Pulsations felt against the needle allow the physician to locate the artery
9. When needle is centered on the artery, the needle is advanced
10. To place the needle in the lumen of the artery, the needle is angled so that it is parallel to the skin and is slowly withdrawn until there’s a backflow of blood
11. The flexible end of the guidewire is inserted through the needle and advanced at least 6 to 10 cm in the vessel.
12. The needle is removed over the guidewire while pressure is applied to the puncture site
13. A vessel dilator is placed over the guidewire and inserted in the artery.
14. A vessel dilator is placed over the guidewire and inserted in the artery.
