Procedure

1. Table setup:

Protip:
Separate Coons dilators. We use the 16 and 20 French. The other can go to the back table for standby. This eliminates confusion during the rapid access portion of the procedure. Protip:
Arrange instruments. Have tubing clamps and heavy trauma shears immediately available to the physician. Needle driver and Mayo scissors are used for suturing after cannula are in place.

1. Arterial access with ultrasound and micro puncture (Usually left groin)
2. Short sheath wire and 8fr. dilator
3. Pre-close
4. Stiff wire inserted
5. 16fr. Coons dilator
6. Arterial (Aortic) Cannula inserted
7. Pull wire and dilator while MD clamps
8. Venous access (Daniels uses big needle and ultrasound)(Usually right groin)
9. Stiff wire inserted (Usually no pre-close)
10. 20fr. Coons dilator
11. Venous cannula inserted (Hold dilator in place in cannula while advancing)
12. Pull wire and dilator while MD clamps
13. CST hands over sterile portion of circuit
14. Clamp circuit while MD cuts tubing
15. Assist MD in cutting and untwisting circuit
16. Use irrigation syringe to assist MD in air-free connection between circuit and cannula
17. 0-Prolene used to create purse-string closures around each cannula
18. 0-Ethibond used to secure cannulas to skin
19. Suture-locks used ~12” down tubing to further secure circuit
20. Carrot-top cut to ~5” used to protect Perclose sutures from being pulled or cut
21. Bio-patches placed
22. Clean and dress both sites

Securement and anti-bleeding protocol

At the Skin:

• 0-Prolene purse-strings on both cannula secured with Woggle devices.
• Additional deep 0-Prolene stitch through a 3” long carrot-top secured to the cannula with white nylon ties. (Minimum 2 nylon ties)
• Arterial cannula secured with 0-Ethibond at the skin in the provided suture ring.

At the tubing connection

• 0-Ethibond deep skin sutures double-wrapped and tight around the cannula. Both sides.

~8-10”down

• 0-Ethibond deep skin sutures double-wrapped and tight around the cannula. Both sides.

• Suture locks can be used above the knees for further strain relief.

Note: Surgicel can be used at the skin for further bleeding control.

Septostomy

See Septostomy page

Antegrade Perfusion

• Use Arrow short braided sheath on ECMO cart
• Ultrasound and micro puncture used to access SFA below arterial cannula
• Use double-male lure adaptor to attach sheath side-port to arterial cannula vent.
