Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

136
Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Acute Respiratory Failure-III01:30

Acute Respiratory Failure-III

666
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

923
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

1.5K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Acute Respiratory Failure-IV01:23

Acute Respiratory Failure-IV

Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...

Pneumothorax-II01:27

Pneumothorax-II

762
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

    Summary
    This summary is machine-generated.

    Extracorporeal lung support, including extracorporeal membrane oxygenation (ECMO) and extracorporeal carbon dioxide removal (ECCO2R), is a rescue therapy for severe respiratory failure. Current evidence does not show a significant mortality reduction in acute respiratory distress syndrome (ARDS) patients.

    Area of Science:

    • Critical Care Medicine
    • Respiratory Medicine
    • Cardiopulmonary Support

    Background:

    • Mechanical ventilation can be insufficient for severe acute respiratory distress syndrome (ARDS), risking ventilator-induced lung injury (VILI).
    • Hypercapnic respiratory failure in COPD exacerbations and ARDS often necessitates extracorporeal carbon dioxide removal (ECCO2R).
    • Extracorporeal lung support encompasses ECMO and ECCO2R, increasingly used clinically for respiratory failure.

    Purpose of the Study:

    • To review the management of patients requiring extracorporeal lung assist.
    • To focus on the clinical application of Extracorporeal Membrane Oxygenation (ECMO) and ECCO2R.
    • To synthesize current clinical experience and literature regarding these advanced respiratory support modalities.

    Main Methods:

    • Selective literature research.
    • Analysis of clinical experience from the authors.
    • Review of management strategies for extracorporeal lung support.

    Main Results:

    • Extracorporeal lung support is implemented when mechanical ventilation fails or poses risks like VILI.
    • ECCO2R is increasingly used for hypercapnic respiratory failure in COPD and ARDS.
    • No definitive evidence currently supports a significant mortality reduction in ARDS patients with these therapies.

    Conclusions:

    • Extracorporeal lung support, including ECMO and ECCO2R, should be considered a rescue therapy.
    • Further research is needed to establish clear guidelines and demonstrate mortality benefits.
    • Management strategies are based on selective literature and clinical expertise.
