Flail Chest-I01:24

Flail Chest-I

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...
Free-falling Bodies: Example01:05

Free-falling Bodies: Example

An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.

Cellular Injury I: Introduction01:00

Cellular Injury I: Introduction

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...
Cellular Injury II: Classification01:21

Cellular Injury II: Classification

Cellular injury is any process that disrupts a cell’s ability to maintain homeostasis, leading to structural or functional changes. It is broadly classified based on etiology (cause) and mechanism of damage.Classification by EtiologyCellular injury may result from several causes. Hypoxic injury happens due to reduced oxygen delivery, most commonly from inadequate blood supply, such as arterial obstruction; for example, coronary artery thrombosis can cause myocardial infarction. Chemical injury...
Free-falling Bodies: Introduction01:07

Free-falling Bodies: Introduction

All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is not the case.
Cellular Injury IlI: Cellular Death01:11

Cellular Injury IlI: Cellular Death

Cell death is the irreversible loss of cellular structure and function, representing the final stage of severe injury. It plays a key role in both normal physiology and disease.Types of Cell DeathThe two main types are necrosis and apoptosis, though others like necroptosis and pyroptosis also exist.Necrosis:Necrosis is an unregulated form of cell death caused by severe injury such as trauma, toxins, or ischemia. It is characterized by cell swelling, membrane loss, rupture, and leakage of...

Summary

Falls from height significantly increase mortality risk, with greater heights and chest/head injuries correlating with higher Injury Severity Scores (ISS) and death. Deliberate falls also increase mortality risk.

Area of Science:

  • Trauma Surgery
  • Emergency Medicine
  • Public Health

Background:

  • Falls from height (FFH) are a significant cause of severe injury and mortality.
  • Understanding predictors of mortality in FFH is crucial for effective emergency response and prevention strategies.

Purpose of the Study:

  • To investigate the relationship between height fallen, Injury Severity Score (ISS), and mortality.
  • To identify other predictors of mortality, including fall intent and injured body regions.

Main Methods:

  • Retrospective observational study of patients aged 16+ from London Helicopter Emergency Medical Services (HEMS) database (Jan 2008-July 2009).
  • Data included patient demographics, height fallen, ISS, injury patterns, and mortality outcomes.
  • Statistical analyses were performed to determine significant predictors of mortality.

Main Results:

  • 117 patients were included; 29% died. Mean ISS was 28.6, mean height fallen was 9.9m.
  • Height fallen (p < 0.001) and chest/head injuries (p < 0.05) were significant predictors of mortality.
  • Deliberate falls were associated with higher ISS and increased mortality risk.

Conclusions:

  • Height fallen is a significant predictor of mortality and correlates with ISS in FFH.
  • Chest and/or head injuries substantially increase mortality risk following FFH.
  • Findings can inform triage protocols, emergency response, and injury prevention efforts for falls from height.
