Spinal Cord Injury ll: Pathophysiology01:14

Spinal Cord Injury ll: Pathophysiology

23
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...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

5.1K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Flail Chest-II

1.0K
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Secondary Spinal Cord Injury llI: Pathophysiology

51
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Flail Chest-I

1.2K
Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

28
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Area of Science:

  • Public Health
  • Transportation Safety
  • Trauma Research

Background:

  • Cycle rickshaws are a vital urban transport mode in India.
  • Vulnerable road users, including rickshaw occupants and pullers, face high injury and fatality risks.
  • Road traffic accidents (RTAs) pose a significant public health challenge in India.

Purpose of the Study:

  • To investigate the characteristics of cycle rickshaw-related crashes.
  • To analyze the nature of injuries sustained in these accidents.
  • To identify risk factors associated with cycle rickshaw trauma.

Main Methods:

  • A hospital-based observational study was conducted over one year.
  • Data collected from patients presenting to a trauma center emergency department.
  • Information gathered included patient demographics, trauma circumstances, and injury types.

Main Results:

  • The average patient age was 32.1 years, with rickshaw pullers and occupants comprising the study group.
  • Overloading (more than two passengers) was observed in 28.5% of cases.
  • Collisions with moving vehicles (56%) and falls from rickshaws were the most common causes of injury, with overloading being a key contributing factor.

Conclusions:

  • Cycle rickshaw users and pullers are highly susceptible to RTAs.
  • Targeted preventive measures are crucial to reduce injury and mortality.
  • Further research is needed to better understand and mitigate cycle rickshaw-related risks.
