脑死亡患者早期肠内营养不耐受与肠道缺血坏死:3例病例报告及文献复习OA

Brain-dead patients are a significant source for organ transplantation,but complications such as intestinal ischemia and necrosis often affect organ quality.This study retrospectively analyzed the clinical data of three patients who became brain-dead following brain injuries due to different etiologies.All three patients rapidly developed severe enteral nutrition intolerance after early initiation of enteral nutrition,and subsequent organ procurement surgeries confirmed varying degrees of intestinal ischemic necrosis.The occurrence of severe intolerance following early enteral nutrition in brain-dead patients may signal the presence of intestinal ischemia and necrosis.Clinicians should be vigilant regarding such signs,promptly assess intestinal perfusion and structural damage,and further research is needed in the future to optimize nutritional support strategies for brain-dead patients and improve the quality of organs obtained.
