在平时,创伤是致死的第四位原因,在战时,因枪炮等武器所造成的创伤占战伤中的绝大部分。预测今后不论平时或战时,创伤均有增加的趋势。因此,创伤是现代医学中一个很重要的研究领域。近年来,我国在这方面进行了大量的基础研究,现将部分研究成果介绍如下。一、创伤弹道学研究七十年代后期,中国开始了系列的创伤弹道学实验研究。自1981～1993年,中国先后召开过四次全国性创伤弹道学术交流会。1988年,中国还主持召开过第6届国际创伤弹道学会议。其主要研究成果有以下几方面:1.远达效应:对385只狗和30只猪的实验观察,发现不同部位(后肢、下腹部、头颅、颌面)致伤后,其远隔部位发生斑块状或条索状出血及血肿者占50%以上。以7.62mm 和5.56mm 弹分别射击狗头颅和后肢,射击前 In normal times, trauma is the fourth cause of death. In wartime, wounds caused by guns and other weapons account for the vast majority of war injuries. It is predicted that there will be an increasing trend of trauma regardless of peacetime or wartime. Therefore, trauma is a very important research field in modern medicine. In recent years, our country has conducted a great deal of basic research in this area. Some of the research results are as follows. I. Traumatic Ballistics Study In the late seventies, China began a series of experimental studies on wound ballistics. From 1981 to 1993, China held four national trauma ballistic academic exchanges. In 1988, China also chaired the 6th International Conference on Wound Trajectory. The main research results are as follows: 1. Far-reaching effect: The experimental observation of 385 dogs and 30 pigs, found that different parts (hindlimb, lower abdomen, head, maxillofacial) after injury, the remote site occurred Plaque or cord-like hemorrhage and hematoma accounted for more than 50%. To 7.62mm and 5.56mm shells were shot dogs head and hind, before shooting
