Veno-venous extracorporeal membrane oxygenation: cannulation techniques.

Area of Science:

• Critical Care Medicine
• Cardiopulmonary Support
• Medical Technology

Background:

• Extracorporeal membrane oxygenation (ECMO) provides an alternative for severe cardiac/respiratory failure unresponsive to conventional therapies.
• Veno-venous ECMO (VV-ECMO) offers comprehensive respiratory support but carries risks like bleeding and infection.
• ECMO management involves multidisciplinary teams for critically ill adult patients.

Purpose of the Study:

• To review indications for VV-ECMO.
• To discuss patient assessment and ultrasound-guided cannulation.
• To explore different VV-ECMO configurations: single, double, and triple cannulation.

Main Methods:

• Review of current literature on VV-ECMO techniques.
• Focus on patient selection and procedural aspects.
• Analysis of advanced cannulation strategies including triple cannulation.

Main Results:

• VV-ECMO configurations range from single to triple cannulation.
• Triple cannulation (VAV/VAPa) expands VV-ECMO applications but increases complexity.
• Ultrasound guidance is crucial for safe vessel puncture.

Conclusions:

• VV-ECMO is a vital tool in intensive care for respiratory failure.
• Understanding different cannulation strategies is key to optimizing VV-ECMO therapy.
• Advanced techniques like triple cannulation require careful consideration of risks and benefits.
