1. Indications

Severe Heart and Lung Dysfunction ECMO/ECLS is indicated for patients experiencing critical conditions that severely impair heart and lung function, necessitating temporary mechanical support.

Respiratory Failure This procedure is often performed in cases of acute respiratory failure where conventional ventilation methods are insufficient to maintain adequate oxygenation and carbon dioxide removal.

Cardiac Failure ECMO/ECLS may be indicated in instances of cardiac failure, particularly when the heart is unable to pump effectively, leading to inadequate blood circulation.

Congenital Heart Defects Neonates and young children with congenital heart defects may require ECMO/ECLS to support their cardiovascular system during surgical interventions or while awaiting corrective procedures.

2. Procedure

Step 1: Patient Preparation The procedure begins with the careful preparation of the patient, which includes obtaining informed consent and ensuring that all necessary equipment is ready for use. The patient is typically monitored closely to assess vital signs and overall stability prior to the procedure.

Step 2: Vein Localization Using ultrasound guidance, the physician locates the appropriate vein for cannulation, which is often the right jugular vein or the right femoral vein, depending on the chosen technique for ECMO/ECLS.

Step 3: Venous Puncture A hollow needle is then used to puncture the selected vein. This step is critical as it allows for the introduction of a guidewire into the vessel.

Step 4: Guidewire Insertion After puncturing the vein, a guidewire is carefully introduced. The placement of the guidewire is confirmed using fluoroscopy to ensure accurate positioning within the vascular system.

Step 5: Vessel Dilation The vessel is then serially dilated to create sufficient space for the cannula or introducer unit. This dilation is performed gradually to minimize trauma to the vessel.

Step 6: Cannula Insertion Once the vessel is adequately dilated, the cannula or introducer unit is advanced over the guidewire into the correct position. The positioning is again confirmed using fluoroscopy to ensure optimal placement.

Step 7: Circuit Connection After confirming the correct placement of the cannula, the guidewire and introducer are removed. The cannula is then clamped, and the previously primed ECMO/ECLS circuit is connected to initiate the life-sustaining treatment.

3. Post-Procedure

Post-procedure care involves close monitoring of the patient for any complications related to cannulation, such as bleeding, infection, or thrombosis. Continuous assessment of hemodynamic status and oxygenation levels is essential to ensure the effectiveness of the ECMO/ECLS support. The healthcare team will also monitor for any signs of cannula displacement or malfunction. Regular imaging may be performed to assess the position of the cannula and the function of the ECMO/ECLS circuit. The duration of support typically ranges from three to ten days, depending on the patient's clinical condition and response to treatment. Once the underlying issue is resolved, a careful weaning process from ECMO/ECLS will be initiated, followed by appropriate follow-up care to ensure recovery.
