An Experimental Study of the Spinal Cord Injury Caused by the Remote Effects of Shock Waves in Head Gunshot with 7. 62 mm Bullet in Dogs
Lei Peng, et al( Department of Newosurgery, Changzheng Hospital)
Thirty dogs were made into the experimental models of penetrating craniocerebral injury, and tangential brain and skull injuries, respectively. The shooting distance was 20 m. The indexes in physiology and roentgenology were observed, and the contents of spinal cord water, Evans blue dye, and sodium and potassium were estimated. Moreover, the pathological changes in spinal cord were examined. The results show that not only the brain itself but also the spinal cord could be damaged. So the injury of spinal cord should not be neglected in the treatment of the wound. The spinal cord injury may by related to the transmission of the bullet kinetic energy and the remote effect of shock waves.
