Bone Marrow Sampling and Transplants

788
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Hemodialysis II: Procedure and Complications

532
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Summary
This summary is machine-generated.

Image-guided percutaneous core needle biopsies (PCNBs) often cause a moderate drop in haematocrit (Ht) and haemoglobin (Hb) levels. This decrease is usually not clinically significant and does not indicate bleeding if no hemodynamic compromise is present.

Area of Science:

  • Interventional Radiology
  • Oncology
  • Hematology

Background:

  • Image-guided percutaneous core needle biopsies (PCNBs) are crucial for diagnosing various lesions.
  • Monitoring changes in haematocrit (Ht) and haemoglobin (Hb) post-biopsy is important for patient safety.

Purpose of the Study:

  • To assess the clinical significance of haematocrit (Ht) and haemoglobin (Hb) variations after image-guided PCNBs.
  • To establish expected Ht and Hb level changes post-biopsy.

Main Methods:

  • Retrospective analysis of 105 patients undergoing image-guided PCNBs.
  • Comparison of pre- and post-procedural Ht and Hb values.
  • Evaluation of complication rates and correlation with Ht/Hb changes.

Main Results:

  • A significant mean decrease in Ht (38.75% to 36.49%) and Hb (12.79 g/dl to 12.03 g/dl) was observed post-PCNB (p<0.0001).
  • 88.6% of patients showed decreased Ht, and 89.5% showed decreased Hb.
  • Minor bleeding (3.8%) occurred without hemodynamic compromise, even with >4% Ht or ≥1.5 mg/dl Hb decrease in some cases.

Conclusions:

  • A moderate post-PCNB decrease in Ht and Hb is expected.
  • Such decreases are generally not indicative of significant bleeding unless accompanied by hemodynamic instability.
  • Clinical monitoring should focus on signs of hemorrhage rather than solely on Ht/Hb values.
