胃肠道为辐射敏感组织之一,在照射后胃肠道症状出现很早,其严重程度与剂量有关。近年来国内研究曾发现急性放射病及其复合伤的病程中,并发肠套叠造成死亡者也为数不少。上述情况表明,急性放射病时有明显的胃肠道运动功能障碍,这种障碍与放射病的发展和转归密切相关。 Gastrointestinal tract is one of the radiation-sensitive tissues, gastrointestinal symptoms appear very early after irradiation, and its severity is related to dosage. In recent years, domestic studies have found that acute radiation sickness and its composite injury in the course of congenital intussusception caused a large number of deaths. The above situation shows that there is obvious gastrointestinal motility dysfunction in acute radiation sickness, which is closely related to the development and prognosis of radiation sickness.
