摘要
191只大鼠受单纯超压后64只于30min内死亡,心脏病变特点为:①心壁血液循环障碍;②气栓形成,气泡并溢入心肌间质;③心肌变性坏死、断裂及闰盘解离。分析心肌病变主要由于超压直接效应、气栓影响及心肺相互影响所致。防护心肺损伤是避免或减少速发死亡的关键。
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.
