Disorders of Erythrocytes01:27

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
Factors Affecting Respiration01:24

Factors Affecting Respiration

Respiration is a crucial physiological function involving exchanging oxygen (O2) and carbon dioxide (CO2) between an organism and its environment. Various factors can impact this essential process:
Hemodialysis II: Procedure and Complications01:24

Hemodialysis II: Procedure and Complications

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,...
Hemoglobin01:24

Hemoglobin

Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...
Hypoxia01:23

Hypoxia

Hypoxia is a medical condition characterized by an inadequate oxygen supply to body tissues. It typically manifests as a bluish discoloration of the skin and mucosae, especially in fair-skinned individuals, when hemoglobin (Hb) saturation drops below 75%.
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...

Area of Science:

  • Internal Medicine
  • Hematology

Context:

  • Hospital-acquired anemia is a frequent complication, particularly in critically ill patients.
  • Limited data exists on its prevalence and risk factors in general ward populations.
  • This study investigates hospital-acquired anemia and hemoglobin drop in non-critical care settings.

Purpose:

  • To determine the prevalence and characteristics of hospital-acquired anemia.
  • To identify clinical factors associated with anemia development and hemoglobin concentration decrease (≥ 2 g/dl) in hospitalized patients.
  • To analyze risk factors for a significant drop in hemoglobin levels.

Summary:

  • A prospective study of 192 general ward patients found anemia in 72.4%, with 26% developing it during hospitalization.
  • A hemoglobin drop of ≥ 2 g/dl occurred in 24.48% of patients.
  • Independent predictive factors for hemoglobin decrease included leukocytosis, extended hospitalization (≥ 7 days), high-volume parenteral hydration (≥ 1500 ml/day), and central venous access.

Impact:

  • Highlights the high prevalence of hospital-acquired anemia in general wards.
  • Identifies key modifiable and non-modifiable risk factors for hemoglobin decline.
  • Informs clinical practice for anemia prevention and management strategies in hospitalized patients.
