Summary
Blood suspension stability is significantly reduced following upper gastrointestinal tract obstruction. This rapid red blood cell separation indicates altered physicochemical blood properties after conditions like cardiac end of stomach, pylorus, or jejunum obstruction.
Area of Science:
- Biomedical science
- Physiology
- Hematology
Background:
- Upper gastrointestinal tract obstruction can impact systemic physiological functions.
- Understanding blood's response to obstruction is crucial for patient management.
Purpose of the Study:
- To investigate the impact of upper gastrointestinal tract obstruction on blood suspension stability.
- To determine if obstruction affects the rate of red blood cell sedimentation.
Main Methods:
- Studied blood samples from subjects with induced obstruction at specific sites (cardiac stomach, pylorus, jejunum).
- Measured the rate of red blood cell separation from plasma (sedimentation time).
Main Results:
- Blood samples from obstructed subjects showed significantly faster red blood cell separation compared to normal.
- Observed variations in sedimentation time correlated with changes in blood's physicochemical status.
Conclusions:
- Upper gastrointestinal tract obstruction adversely affects blood suspension stability.
- Altered physicochemical properties of blood are the underlying cause of rapid sedimentation post-obstruction.

01:07Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
01:29Intestinal Obstruction I: Introduction
Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
01:22Lifecycle of Erythrocytes
Erythrocytes, also known as red blood cells, constantly move through blood capillaries. As a result, they damage their plasma membrane due to the continuous friction. Typically, after 100 to 120 days, erythrocytes become rigid and fragile as they wear out. As they pass through small vessels in the spleen and liver, they can get trapped and break apart into fragments.
The resident phagocytic macrophages deal with these damaged cells by engulfing them and separating their globin and heme groups.

01:24Factors Affecting Erythropoiesis
The cardiovascular system regulates the number of erythrocytes in the bloodstream to ensure optimal oxygen transport. It also prevents over-proliferation of these cells, which helps to maintain blood viscosity and flow rate.
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
