Abstract
Background: A large variety of injuries is sustained during vehicular accidents. Blunt cardiac injury (BCI) encompasses a wide spectrum of clinical manifestations, ranging from cardiac concussion to cardiac rupture. Apart from the usual blunt injuries, an uncommon type is the compression injuries of the chest. Such compression results not only in direct damage to the solid organs but also results in blast injury of fluid filled organs due to the variations in the intraluminal pressure, in accordance with laws of fluid dynamics.
Case Report: Here is a rare and interesting case of such nature, in which tangential force over the chest resulted in the massive rise of intraluminal pressure in the ventricles leading to burst of chambers resulting in death.
Conclusion: In this article, we have tried to explain the various factors resulting in bursting of the fluid filled organs and their relations with fluid dynamics.
- Fluid dynamics
- Fluid filled organs
- Compression injuries
- Burst injuries
