Insights

Partial exchange transfusion (PET) for polycythemia hyperviscosity syndrome (PHS) in infants showed no change in usage over time. PHS and PET are linked to complications, necessitating further research on their long-term risks and benefits.

Area of Science:

  • Neonatology
  • Pediatric Hematology

Background:

  • Polycythemia hyperviscosity syndrome (PHS) is a condition affecting newborns.
  • Risk factors for PHS include maternal diabetes, and it can lead to significant complications.

Purpose of the Study:

  • To analyze the trends in partial exchange transfusion (PET) for PHS in infants.
  • To evaluate the associated risk factors and complications of PHS and PET.

Main Methods:

  • Retrospective review of 141 infants treated with PET for PHS between 1986 and 2007.
  • Data collected included patient demographics, PHS risk factors, PET indications, and complications.

Main Results:

  • No significant change in the number of PET procedures performed over the 20-year study period.
  • Maternal diabetes decreased as a risk factor over time.
  • Forty percent of patients experienced PHS complications pre-PET; 18% had PET-related complications. Life-threatening events were rare.

Conclusions:

  • PHS remains a concern in neonatal intensive care units, especially in high-risk infants.
  • Both PHS and PET are associated with notable complications.
  • Further long-term studies are required to fully understand the risks and benefits of PET for PHS.

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

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...

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
Blood Transfusion01:15

Blood Transfusion

Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...
Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
