Insights

This review details cardiopulmonary bypass (CPB) coagulopathy, covering its history, CPB circuit components, and current knowledge on pathogenesis, prevention, and treatment strategies.

Area of Science:

  • Cardiovascular Surgery
  • Hematology

Background:

  • Cardiopulmonary bypass (CPB) is frequently associated with coagulopathy, a significant clinical challenge.
  • Numerous publications exist, necessitating a consolidated overview of the topic.

Purpose of the Study:

  • To provide a comprehensive review of cardiopulmonary bypass (CPB) coagulopathy.
  • To summarize the history, components, pathogenesis, prevention, and treatment of CPB-induced coagulopathy.
  • To discuss coagulation monitoring and transfusion support in the context of CPB.

Main Methods:

  • Literature review synthesizing existing publications on CPB coagulopathy.
  • Analysis of historical and current CPB technologies and supportive care.
  • Emphasis on near-patient testing for intra- and postoperative coagulation monitoring.

Main Results:

  • CPB circuits have evolved significantly, impacting coagulopathy.
  • Understanding of CPB coagulopathy pathogenesis, prevention, and treatment has advanced.
  • Near-patient testing and updated transfusion strategies are crucial.

Conclusions:

  • Effective management of CPB coagulopathy requires understanding its multifaceted nature.
  • Technological advancements and monitoring techniques have improved patient care.
  • A comprehensive approach to coagulation management is essential for CPB patients.

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...
Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
