Increased Intracranial Pressure ll: Pathophysiology

2
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

14.9K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Spinal Cord Injury ll: Pathophysiology

7
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...

Healing II: Complications01:24

Healing II: Complications

22
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Pneumothorax II: Pathophysiology01:08

Pneumothorax II: Pathophysiology

21
Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance...

Cellular Injury I: Introduction

6
Cellular injury occurs when a cell cannot maintain homeostasis or adapt to stressors such as hypoxia, toxins, or trauma. Depending on severity and duration, injury may be reversible, allowing recovery, or irreversible, leading to cell death.General Mechanisms of Cell InjuryAlthough causes vary, most cellular injuries arise from a few key mechanisms that disrupt essential functions and often amplify one another. Cell survival depends on the extent and balance of these disturbances.ATP depletion...

Summary
This summary is machine-generated.

Pressure induced deep tissue injury (DTI) results from direct cell deformation within minutes or blood vessel occlusion over hours. Understanding these mechanisms is key for preventing DTI.

  • Biomedical Engineering
  • Cell Biology
  • Tissue Mechanics

Background:

  • Pressure ulcers are a significant clinical concern.
  • Deep tissue injury (DTI) is a specific type of pressure ulcer.
  • The underlying mechanisms of DTI require further elucidation.

Purpose of the Study:

  • To investigate the mechanisms of pressure induced deep tissue injury (DTI).
  • To understand the cellular and tissue-level responses to pressure.
  • To correlate experimental findings with clinical observations.

Main Methods:

  • A multi-scale approach was utilized, encompassing in vitro cell cultures.
  • Tissue-engineered muscle models were employed.
  • In vivo studies using small animal models were conducted.

Main Results:

  • Two primary damage mechanisms were identified: direct deformation and ischemic damage.
  • Direct deformation, caused by high strains, leads to rapid cell damage (minutes).
  • Ischemic damage, due to blood vessel occlusion, develops over several hours.

Conclusions:

  • The study clarifies the distinct temporal and mechanical pathways leading to DTI.
  • Findings provide a basis for developing novel preventative strategies for DTI.
  • Clinical implications for pressure ulcer management are discussed.
