脑卒中(stroke)是指急性脑部血液循环障碍所导致的局限性或全面性脑功能损害综合症,是导致人类死亡的三大疾病之一~([1])。脑卒中患者常伴有意识障碍,为保证机体营养成分及药物的及时供给,留置胃管进行鼻饲,已成为脑卒中患者综合治疗的重要手段~([2])。鼻饲病人鼻饲前需监测胃内残留量(gastric residual volume,GRV),判断肠内营养是否耐受~([3])。临床观察发现,胃管留置长度会影响GRV的监测。改良法测
Stroke is a limited or comprehensive syndrome of brain damage caused by acute blood circulation disorders in the brain. It is one of the three major causes of human death (1). Stroke patients often accompanied by disturbance of consciousness, in order to ensure the body’s nutrients and drugs in a timely manner, leaving the tube for nasal feeding has become an important tool for comprehensive treatment of stroke patients (2). Nasal feeding patients need to monitor the gastric residual volume (GRV) before nasal feeding to determine if the enteral nutrition is tolerable ~ ([3]). Clinical observation found that gastric tube indwelling length will affect the monitoring of GRV. Improved law test
