Extracorporeal Carbon Dioxide Removal (ECCOR) is a medical procedure involving removing carbon dioxide (CO2) from the blood outside the body. It is a form of extracorporeal membrane oxygenation (ECMO) therapy that temporarily supports patients with severe respiratory failure. ECCOR focuses explicitly on removing excess CO2 while maintaining sufficient oxygenation levels. Removing CO2 from the blood helps improve respiratory function and reduce lung strain.

ECCOR works by using a specialised device known as a membrane lung. This device acts as an artificial lung, allowing blood to flow through it and exchange CO2 and oxygen across a semipermeable membrane. The CO2 is diffused from the blood into a gas phase, while oxygen is absorbed into the blood. By aiding in CO2 removal, ECCOR supports respiratory function, potentially reducing the need for invasive ventilation and associated risks in critically ill patients.

How Does It Help?

ECCOR is primarily used in the management of acute respiratory failure, especially in patients with ailments such as acute respiratory distress syndrome (ARDS) or severe exacerbations of chronic obstructive pulmonary disease (COPD). These conditions can lead to dangerously high levels of CO2 in the blood, causing respiratory distress and organ dysfunction. ECCOR helps to alleviate these symptoms by effectively removing excess CO2 and restoring normal acid-base balance.

ECCOR allows lungs to rest and heal by reducing their workload. It is particularly beneficial in cases where mechanical ventilation alone may not be sufficient or cause further lung damage. ECCOR provides a gentler and more controlled approach to managing CO2 levels, allowing for better patient outcomes and potentially reducing the duration of mechanical ventilation.

Preparation

  • Preoperative Analysis: Before undergoing ECCOR, a patient will typically undergo a thorough evaluation to assess their suitability for the procedure. This evaluation may include medical history and various tests such as blood examinations, imaging studies, and lung function tests. 

  • Patient Preparation: Once deemed eligible for ECCOR, the patient will be prepared for the procedure. It includes the placement of arterial and venous catheters, which allow for the withdrawal and return of blood during the ECCOR process. 

  • Fasting: Doctors may advise fasting or refraining from eating or drinking for a specific time before the procedure to minimise the risk of aspiration during sedation or anaesthesia.

The medical staff will closely monitor the patient during the procedure to ensure their safety and well-being.

Treatment

During ECCOR treatment, blood is withdrawn from the patient's body through the venous catheter and passed through the membrane lung. In the membrane lung, the blood is exposed to a gas mixture that facilitates the removal of CO2 and the addition of oxygen. The arterial catheter returns the oxygenated blood to the patient's body.

ECCOR treatment is typically conducted in an intensive care unit (ICU) or a specialised ECMO centre. The duration of treatment can vary and depends on the patient's condition and response to therapy. Continuous monitoring of the patient's vital signs, blood gases, and other parameters is essential to ensure the effectiveness and safety of the ECCOR treatment.

Post-Treatment

After ECCOR treatment, patients may require ongoing monitoring and support to ensure a smooth recovery. These may involve close observation in the ICU, continued mechanical ventilation, and additional treatments as necessary. The patient's progress will be closely monitored to assess their response to ECCOR and to determine the appropriate next steps in their care.

Healthcare professionals may recommend physical rehabilitation and respiratory therapy to help the patient regain optimal lung function and overall health. Follow-up appointments with healthcare providers will be scheduled to assess the long-term outcomes of ECCOR and to provide any necessary ongoing care.

Benefits

ECCOR offers several key benefits in the management of respiratory failure: 

  • It provides a more targeted approach to CO2 removal, allowing for better control of acid-base balance. These can help prevent complications related to high CO2 levels, such as respiratory acidosis and organ dysfunction.

  • ECCOR reduces the strain on the lungs by providing temporary respiratory support. It can be particularly advantageous in patients with severely compromised lung function, where mechanical ventilation alone may not be sufficient or may cause further damage. 

  • ECCOR allows the lungs to rest and heal, potentially improving overall lung function and reducing the need for prolonged mechanical ventilation.

  • ECCOR has the potential to improve patient outcomes and survival rates in cases of severe respiratory failure. By effectively managing CO2 levels and maintaining adequate oxygenation, ECCOR can support the body's vital organs and give patients a better chance of recovery.

Risks

As with any medical procedure, ECCOR carries certain risks and potential complications. These can include bleeding, infection, damage to blood vessels, and adverse reactions to anticoagulant medications used during ECCOR. There is also a risk of air embolism, where air bubbles enter the bloodstream and cause blood vessel blockages.

Additionally, ECCOR requires close monitoring and specialised care. Not all medical facilities have the expertise and resources to perform ECCOR, so access to this treatment may be limited in certain locations. It is crucial for patients to receive ECCOR in a centre with experienced healthcare professionals who can effectively manage any potential complications.

What makes it so unique

ECCOR stands out as a unique and specialised treatment modality for patients with severe respiratory failure. Its ability to selectively remove CO2 and provide oxygenation support sets it apart from other interventions. ECCOR offers a tailored approach to managing CO2 levels, allowing for better control and preventing complications.

The use of ECCOR also highlights the importance of a multidisciplinary approach to patient care. It requires the collaboration of various healthcare professionals, including intensivists, respiratory therapists, perfusionists, and nurses, to ensure the safe and effective delivery of ECCOR. This teamwork and expertise contribute to the success and unique nature of ECCOR as a treatment modality.

FAQs

‍What is Extracorporeal CO2 Removal (ECCO2R)?

ECCO2R is a medical procedure that assists in removing carbon dioxide (CO2) from a patient's blood when their lungs cannot adequately perform this vital function. The procedure involves circulating a portion of the patient's blood through an extracorporeal circuit, where it passes through a membrane gas exchanger. This device separates CO2 from the blood and replaces it with oxygen, similar to the gas exchange that occurs naturally in the lungs.

How does ECCO2R differ from extracorporeal membrane oxygenation (ECMO)?

While both ECCO2R and extracorporeal membrane oxygenation (ECMO) are forms of extracorporeal life support (ECLS), they serve different purposes and operate in various capacities. ECMO provides oxygenation and CO2 removal for patients experiencing severe respiratory or cardiac failure. It is a form of heart-lung bypass outside the body.

ECCO2R, on the other hand, focuses primarily on removing CO2 from the blood. It is typically used when a patient's primary issue is hypercapnia (excess CO2) rather than hypoxemia (low oxygen levels). As such, ECCO2R requires less blood flow than ECMO, which makes it less invasive and potentially lowers the risk of complications.

What are the indications for ECCO2R therapy?

ECCO2R therapy is primarily indicated for patients with acute respiratory failure who have hypercapnic complications. Common conditions that warrant the use of ECCO2R include acute exacerbations of chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and status asthmaticus when conventional therapies have failed or are contraindicated.

How does ECCO2R help in managing respiratory failure?

ECCO2R helps manage respiratory failure by taking over part of the gas exchange function the compromised lungs struggle to perform. By removing CO2 from the blood extracorporeally, the therapy allows the lungs to rest and potentially recover, reducing the risk of ventilator-induced lung injury (VILI).

Is ECCO2R invasive or non-invasive?

ECCO2R is an invasive procedure because it requires vascular access to allow blood to flow from the patient to the extracorporeal circuit and back again. It is typically achieved by inserting catheters into large veins or sometimes arteries, depending on the specific ECCO2R system and the patient's condition.

Despite its invasive nature, ECCO2R is often considered less invasive than ECMO due to its requirement for lower blood flow rates and the potential for using smaller cannulas. It can lower the risk of complications associated with vascular access and anticoagulation.

What are the components of an ECCO2R system?

An ECCO2R system comprises several essential components. The system's core is the gas exchange device or membrane gas exchanger, similar to the artificial lung and the pump, which propels the blood through the circuit. The system also includes tubes or cannulas connecting the patient's circulation to the extracorporeal circuit and back. Monitoring devices are also an integral part of the ECCO2R system. They continuously measure parameters such as blood flow, oxygenation, and CO2 levels, ensuring the safety and effectiveness of the therapy.

How does ECCO2R work in removing carbon dioxide from the blood?

The principle behind ECCO2R is straightforward. Blood is drawn from the patient through a venous catheter and pumped through the extracorporeal circuit. As the blood passes through the membrane gas exchanger, CO2 diffuses out of the blood and is replaced with oxygen.

Can ECCO2R be used in patients with acute exacerbations of COPD?

ECCO2R can be particularly beneficial for patients experiencing acute exacerbations of COPD. These patients often suffer from acute or chronic hypercapnic respiratory failure, where the body accumulates excessive CO2 due to the inability of the lungs to expel it effectively. By reducing the levels of CO2, ECCO2R can alleviate breathing problems and allow for more protective mechanical ventilation settings. It can be crucial in preventing further lung injury and allowing patients to recover from an exacerbation. ECCO2R also holds the potential to avoid intubation in certain COPD exacerbations, which can improve patient comfort and outcomes.

What are the advantages of ECCO2R over invasive mechanical ventilation?

ECCO2R offers several advantages over invasive mechanical ventilation, particularly for patients who are at risk of ventilator-associated lung injuries. ECCO2R reduces the stress and strain on the lungs by allowing for lower tidal volumes and pressures. It also minimises the risk of barotrauma, volutrauma, and biotrauma associated with mechanical ventilation.

ECCO2R also facilitates a more "lung-protective" ventilation strategy, which is beneficial in conditions like ARDS, where the lung tissue is particularly fragile. Furthermore, ECCO2R may provide a means for patients to be more awake and interactive, improving their quality of life during treatment.

What types of ECCO2R devices are available?

Several types of ECCO2R devices are available, each designed to cater to different patient needs and clinical scenarios. These devices vary in gas exchange efficiency, blood flow requirements, and cannula size used for vascular access.

Some ECCO2R devices are designed for short-term use and are ideal for emergencies or acute exacerbations of chronic conditions. Others are built for longer-term support and can be beneficial in cases where prolonged respiratory assistance is needed, such as bridge-to-transplant scenarios.

How long can ECCO2R therapy be utilised in a patient?

The duration of ECCO2R therapy can vary widely depending on the patient's condition, response to treatment, and underlying disease process. Some patients may require ECCO2R for only a few days, while others may need it for weeks or even months.

Can ECCO2R be used as a bridge to lung transplantation?

ECCO2R can be used as a bridge to lung transplantation for patients with end-stage lung disease who experience acute respiratory decompensation. This therapy can stabilise the patient's gas exchange and hemodynamics, allowing them to remain viable candidates for transplantation while waiting for suitable donor lungs.

Is ECCO2R used in paediatric patients?

ECCO2R is used in paediatric patients, although its application is less common than in adults. Healthcare professionals may carefully tailor this therapy to children's unique physiological characteristics, including their smaller blood volume and different metabolic rates. Paediatric use of ECCO2R requires specialised equipment and expertise to ensure its safety and effectiveness.

Can ECCO2R improve outcomes in patients with acute respiratory distress syndrome (ARDS)?

ECCO2R can potentially improve outcomes in patients with ARDS by enabling lower tidal volumes and pressures during mechanical ventilation, which aligns with lung-protective ventilation strategies. It can reduce the risk of ventilator-induced lung injury and allow the lungs to heal.

What are the contraindications for ECCO2R therapy?

Contraindications for ECCO2R therapy include conditions that increase the risk of complications from the procedure, such as severe coagulopathy, active bleeding, or a high risk of bleeding due to anticoagulation therapy required for ECCO2R. Other contraindications may include severe hemodynamic instability and terminal illnesses where ECCO2R is unlikely to provide a meaningful benefit.

Is ECCO2R associated with any complications?

Like all invasive medical procedures, ECCO2R has a few potential complications. These can include bleeding, infection, thrombosis, technical issues with the equipment, and hemodynamic instability. The risk of complications can be mitigated by proper patient selection, meticulous insertion and maintenance of vascular access, and rigorous monitoring during therapy.

How is blood access achieved for ECCO2R therapy?

Blood access for ECCO2R therapy is typically achieved by inserting cannulas into large central veins, such as the femoral, jugular, or subclavian veins. However, healthcare providers may also use arterial access, depending on the ECCO2R system and the patient's circulatory needs.

Can ECCO2R be performed in the ICU setting?

ECCO2R is primarily performed in the intensive care unit (ICU) setting, where critically ill patients can be closely monitored and managed by a multidisciplinary team. The ICU provides the necessary infrastructure, including advanced monitoring and support equipment and the specialised staff required to manage ECCO2R therapy.

How does ECCO2R affect haemodynamics?

ECCO2R can affect a patient's haemodynamics, depending on the system used and the patient's condition. In some cases, ECCO2R can improve cardiac output by reducing the work of breathing and the intrathoracic pressures associated with mechanical ventilation.

However, ECCO2R can also lead to hemodynamic instability due to factors such as changes in intravascular volume, the effects of anticoagulation, and alterations in systemic vascular resistance. Careful monitoring and managing fluid status and cardiovascular support are essential during ECCO2R therapy.

Is ECCO2R a replacement for mechanical ventilation?

ECCO2R is not a replacement for mechanical ventilation but rather a complementary therapy. It can be used in conjunction with mechanical ventilation in patients who are not adequately managed by conventional ventilation strategies alone. By taking over a portion of the gas exchange process, ECCO2R can allow for more protective ventilation settings.

What parameters are monitored during ECCO2R therapy?

During ECCO2R therapy, the medical staff continuously monitor several parameters to ensure the safety and efficacy of the treatment. These include blood flow through the extracorporeal circuit, CO2 removal rates, oxygenation levels, blood pressure, heart rate, and anticoagulation status. Monitoring also includes regular assessments of the patient's respiratory function, blood gases, and overall clinical condition.

Can ECCO2R be used in patients with chronic respiratory failure?

ECCO2R can be used in patients with chronic respiratory failure, mainly when acute exacerbations occur or when other therapies do not adequately manage chronic hypercapnia. In these cases, ECCO2R can provide temporary support to improve gas exchange and reduce breathing work while other treatments are optimised or until the patient recovers from the exacerbation.

How does ECCO2R impact patient outcomes?

ECCO2R has the potential to positively impact patient outcomes by improving gas exchange, reducing the intensity of mechanical ventilation, and potentially preventing complications associated with conventional ventilation strategies. 

Is ECCO2R used in conjunction with other respiratory support therapies?

ECCO2R is often used with other respiratory support therapies, including mechanical ventilation, non-invasive ventilation, inhaled medications, and prone positioning. The combination of these therapies is tailored to each patient's individual needs and clinical condition.

Can ECCO2R be utilised outside of the ICU?

Currently, ECCO2R is predominantly used in the ICU due to the critical nature of the patients who require this therapy and the need for intensive monitoring and management. However, as technology advances and becomes more portable, there may be potential for ECCO2R to be used in other settings in the future.

How does ECCO2R therapy affect oxygenation?

While ECCO2R primarily focuses on removing CO2, it can also contribute to oxygenation. The membrane gas exchanger adds oxygen to the blood by removing CO2, which can help improve a patient's oxygen levels. However, additional oxygenation support, such as ECMO, may be necessary if a patient has severe hypoxemia.

What is the role of ECCO2R in weaning patients from mechanical ventilation?

ECCO2R can facilitate weaning patients from mechanical ventilation by allowing for lower ventilator settings and reducing the work of breathing. It can benefit people who have difficulty tolerating reduced support due to the buildup of CO2.

Can ECCO2R prevent ventilator-induced lung injury?

ECCO2R can help prevent ventilator-induced lung injury (VILI) by enabling lower tidal volumes and pressures during mechanical ventilation. Reducing the stress and strain on the lungs through ECCO2R can minimise the risk of barotrauma and other forms of VILI.

Is ECCO2R compatible with prone positioning?

ECCO2R is compatible with prone positioning, a technique often used to manage ARDS and improve oxygenation. When used together, ECCO2R and prone positioning can enhance overall respiratory support and improve patient outcomes.

Can ECCO2R be used in patients with hypercapnic coma?

ECCO2R may be used in patients with hypercapnic coma, where excess CO2 decreases consciousness. By rapidly reducing CO2 levels, ECCO2R can help reverse the coma and stabilise the patient's condition.

What is the cost of ECCO2R therapy?

The cost of ECCO2R therapy can vary depending on the duration of treatment, the type of device used, and the specific healthcare setting. As a specialised and resource-intensive therapy, ECCO2R can be expensive, but the potential benefits for certain critically ill patients may justify the cost.

Can ECCO2R be utilised in patients with status asthmaticus?

ECCO2R can be considered in patients with status asthmaticus who do not respond to conventional treatments. By removing CO2 and reducing the work of breathing, ECCO2R can help stabilise these patients and prevent complications from severe bronchospasm.
