Abstract:
One hundred and ninety-one rats were injured with blast super-pressure and 64 out of the 191 died within 30 minutes after injury.The characteristics of the myocardial damages of the rats were as follows:(1)Disturbance of myocardial circulation;(2)Air embolism and interstitial emphysema;(3)Degeneration and necrosis of the myocardium; severance of myocardial fibers ;and separation of intercalated discs.It was speculated that the causes of these myocardial pathological changes are the direct damage of blast superpressure and the secondary effects of pulmonary damages.Protection of the heart and the lungs from blast super-pressure injury is the key to reduce the number of immediate death in blast injury.
